MYSQL :: MySQL Slow Starting Up

I feel quite stupid I cannot seem to get MYSQL to even run on my Mac (OS X 10.4)

I have installed MYSQL and then went to terminal and entered

cd /usr/local/mysql

then

sudo ./bin/mysqld_safe

then my password as prompted

which is followed by

Starting mysqld daemon with databases from /usr/local/mysql/data

- at this point as it just seems to stop

What next? I have tried entering mysql -u grifkerry -p but nothing happens! I have left it for a while but still nothing.

I need to transfer a database from one computer to another. Both computers are Macintoshes running OS X Panther. Both computers are running MySQL through localhost. The computer to which I am transferring the database has MySQL up and running perfectly fine.

The computer from which I want to get the database is able to query the database through a web application using Perl but when I try to run MySQL from the Unix command line using the following text: "mysql -h localhost -u root -p" I get the following response "-sh: mysql: command not found."

As far as I know, MySQL is installed correctly on this machine (I would assume it has to be in order for the web application to access the database through Perl and MySQL). If I can start and run MySQL, I know that I can dump the database using the "mysqldump" command. Does anyone have any suggestions on what I need to do to get the mysql command to execute correctly so that I can run the program?

im a complete novice regarding mysql

im am trying to start mysql with

c:
et start mysql

and get the system error 1067

I used to have an older version of Mysql (4.0) that I started by starting
Winmysqladmin. Now I replaced this with the newest version: 4.1.12 and that
doesn't have Winmysqladmin. After some experimentation I found out that
MYSQLD.EXE seems to start mysql. I can then use phpMyAdmin.

However, my own application still does not work (I can log in, but my
queries give no results). A possible explanation is that I selected the
UTF-8 fontset.

I would like to have advice of what causes this problem and how I can solve
this. I a using Windows ME.

I am using window xp, I installed mysql 4.0 and it was working fine.
last week, I uninstalled mysql 4.0 and install 4.1 and it's no longer starting.

before, error message said, "mysql failed start, wait 30 then try again"
then I messed around with it. the error message is gone

right now, it doesn't start, it doesn't give me any error message and I can't even get mysql 4.0 working.

I had to reload mysql 4.0.17 on to a Fedora Core machine that was previously
working in the same configuration. Now though I can't get the server to run
with the either of the following commands:

../mysql.server start - the command line reappears with no error but no
running process in the system monitor
/usr/local/mysql/bin/mysqld_safe -user=mysql - this command does not return
to the command prompt so when I hit the enter key I get "Starting mysqld
daemon with databases from /var/lib/mysql 0404124 00:13:21 mysqld ended.

It looks to me as if it attempts to start but fails with no error. What am I
missing on the reinstall?

This may be a very simple question and possibly could have a very simple
solution to it.Since I have been using mysql for less than 2 months,I
still consider myself a newbie.I still cannot execute certain
commands from my dos prompt, but I can run queries easily using
phpmyadmin.I have purchased MYSQL Second Edition (Paul Dubois) so I
hope to put it to good use soon.

The question that is of concern to me this morning is the prefered way
to start mysql.I seem to think that I always have a problem because
when I start my PC,mysql is already running as a service.But I am
thinking that because I login to my PC as any user other than the dbase
username,I have a problem afterwards.

Must I always log on to my PC (Win2K) as the same user as the created
user in my DBase in order for mysql to run properly?

I type in the password and mysql closes. When I reinstall it as an anonymous user mysql asks me to type in my password. I've reinstalled the program a few times. I tried to reset the root password. None of these things work. I also saw that I have a file called prod.err. I open up the file and I see a bunch of stuff that I don't understand. I greatly appreciate anyone who could help me solve this problem. I've run out of ideas.

I installed mysql on a Mac OSX 1.3.9. It worked and ran with no problems. The machine was restarted and mysql will no longer start up. I have tried everything and nothing works. If I look at the logs it basically tells me that mysql starts and then shuts itself off.

i'm trying to change the mysql data path. to do this, i have to shoot down mysql and restart it. i tryed to restart mysql with the program mysqld (i'm using windows xp, mysql server 5.0), but it doesn't work. why? is there any different way to start mysql? there was no error message or something like this. if i start it with mysqld --standalone, it works, but the command window doesn't replay anymore.

I installed mysql with apache but after a while mysql stoped starting. I even reinstalled both mysql and apache but still i can not start mysql. could any one tell me how to fix this problem.

I am just starting to work with MySQL and I have it installed on a separae PC at my home as well. I downloaded and installed it, MySQL Administrator and the query analyzer as well. But I need to know how to create an initial database or does mysql come with a default database?

I am asking because I tried to get in throughthe MySQL Administrator and it prompted for a database name initially that it can be linked to, but I realized there were no databases created. How can I create an initial database or is there some sort of utility window that comes with the MySQL download that I can access the database with? BTW, this is installed on Windows OS.

I have an Excel spreadsheet which has been my source document for the past several years for a collection I own. It has about 2000 entries (records) and each record has ~20 fields. Photographs of each item in the database are an integral part of this.
What I'd like to do is move all of this knowledge onto the web in database fashion and provide a means to allow users to search the database.
I found DaDaBIK which seems to be perfect for the show and tell phase of my project, but I need to create the database properly first.
I can make a mysql database with my hosting account, but I don't know where to start. I know databases can be tricky; at least what I know of Access is tricky, so I want to do this right.

I'm looking for help, maybe a simple tutorial, that will guide me through the process of transforming my Excel data and photos into a mysql database online.

I have googled for this, but there are so many articles, and it is all over my head anyway.

I shutdown my MySQL server using MySQL Administrator 1.0. My problem is that i dont know how to start up the MySQL Server again. I tried to run mysqld-nt.exe by double clicking it but my server will not be up. If i restart my computer then thats the time my MySQL server will be up. Unlike MySQL 4.0.22 if i double click on winmysqladmin.exe my server will be up.

Is there a way to put the server up without restarting my computer?

I have a mysql db (Version: '4.0.22' FreeBSD port: mysql-server-4.0.22) running on an Verio VPS, and I am having an issue: After a power failure on Verio that meant restarted servers, etc, I saw that Mysql was not coming up.

I checked the logs / etc and I got this message on /var/db/mysql/<hostname>.err:

060925 00:15:53 mysqld started
060925 0:15:53 bdb: Recovery function for LSN 1 29049 failed

mysqld in free(): warning: chunk is already free
060925 0:15:53 Can't init databases
060925 0:15:53 Aborting

There is no ./testperl/testab.db anywhere I can see, but OTOH, there should only be a few dbs and none of them is called testperl... Honestly, I have no idea of what might be hapening, but having the db is quite a PITA.

I am in the process of creating a database which will serve as a backend for the registration of users' details and to handle account activation via the use of php scripts. I really need help with starting MySql. I have scoured various forums and followed instructions from the mysql.com, and other such tutorials.

I am creating the website using dreamweaver on a windows 2000 pc but I am planning to place it on the linux box where the apache web server will handle it (if you know what I mean). The linux server is where the php and Mysql are installed. Incidentally the php installation is located in the /etc directory - and it works.

I downloaded the Mysql binary file version 4.0.25 recently. Followed the installation instructions to the letter up to the change of ownership stuff. Code:

I have debian running and this is how I have it setup

# ls -ld /var/lib/mysql
drwxr-xr-x 4 mysql mysql 4096 Aug 19 11:29 /var/lib/mysql

I was shown how to setup a password for user mysql here
http://dle.ascendant.ca/restoring-mysql-root-HOWTO.txt,

because at one time all I would have to do it hit enter after
# mysql -h localhost -p -u mysql
Enter password: (no password is added I just hit enter)
Welcome to the MySQL monitor. Commands end with ; or g.
Your MySQL connection id is 16 to server version: 4.0.14-log

Type 'help;' or 'h' for help. Type 'c' to clear the buffer.

mysql> ( can do whatever I want now???)

If I type in the correct password it lets me in, if I type in no passowrd it
lets me in, if I type in the INCORRECT password it does NOT let me in. How
can I make it so that if no password is typed it still treats it as
incorrect?

I'm starting to play around with MySQL. How can I prevent it from starting up whenever my computer starts? It slows down the startup some, and I'm not always wanting to use it. besides, I can start it myself if I need it.I've had a look on Google for theis, and found quite a few results, but they were fo Linux or Unix. I'm ruinning Windows XP.

i have been running mysql on windows server 2003 for the last almost 2 years (its a really early version of mysql 4 anyway) but now all of a sudden mysql service stopped starting, i can go to services, press start and then refresh and its off again! i have a feeling that someone deleted the core mysql table (mysql) as it is now totally empty.

im not too good with my sql as i generally use mssql or whatever, infact mysql never really installed properly, the only user i could ever use was root but i didnt mind this so i just left it and it was fine for 2 years but now its just stopped all of a sudden and i cant get it back on.

i have enabled the mssql php exension as a backup system but i cant transfer any databases across without enabling mysql.. but it wont turn on! i tried several exes in e:mysqlin but none got it on (well one of them made the little winmysqladmin light go on for half a second)

I have created a user called mysql to administer the mysql installation.

I can run mysqld_safe as the mysql user without any problems, however, when I try to run it as the root user with --user=mysql the process does not start and the following error message appears in the error log.

040706 17:03:06  mysqld started
Fatal error: Can't change to run as user 'mysql' ;  Please check that the user exists!
040706 17:03:06  Aborting

The user does exist, does anyone have any ideas what I am doing wrong?

I had downloaded a few years back mySQL v3.51 installed but never used it. Now I wanted to convert some B-TREE databases to mySQL and did some testing via ODBC to insert 70,000 records: My results:

MS ACCESS: ~60,000 msecs
MYSQL v3.51 ~18,000 msecs

Impressed with the speed, I went ahead and got the latest MySQL v5.1. Uninstalled the older version, I had nothing there to preserve, so I did a simple new install with MySQL v5.1. I noticed the size of the files and BINEXE increasted by 1,000,000%. Ok, Bulky. Not a problem.

I reran the same ODBC test, and now I got:

MYSQL v5.1: ~450,000 msecs or 7.5 freaking MINUTES!

What the hell happen? Nothing was done. I'm knew to MYSQL. I just installed it with all the defaults. I did choose "developer's machine" for the "optimizer wizard"

I can't redistribute MYSQL v3.51 and force it down people's throats! I have to use what they are using already, if already installed. Not even my current system takes 1 minute to add 70,000 records. Why 7.5 minutes? All it is simple inserts/free statements.

I have this one site that slows down all my others because the queries are so massive.

For example one of these queries I use to-do a search by a user's account number. I also get the position he is at on the list, and in order to-do that I need to select ALL the rows.

For example, I filter out the other queries in php.
CODE$num = 1;
$q = mysql_query('SELECT * FROM lists');
while($r = mysql_fetch_assoc($q))
{

   if($r['account']=='accountNum')
   {
         print 'You are at pos. num '.$num.'<br>';
   }
   $num++;
}

I just changed to use MySQL few days ago but it was a bad idea. My server now is running very slowly with the database. I'm using Perl5 and DBD::Mysql in my script. The system is Linux9, Apache2.

I looked at these mysql pid and saw a lot of activities (about 400) while there are more 100 users online at this moment and lots of running under a the same pid number.

I have the long query time set to 15 yet MySQL is still showing results with a query time of 0 in the slow query log.

It says enter time in "seconds" in the MySQL Administrator but did it mean in milliseconds??

mySQL has been running very slowly and I am getting errors. First I did 2 things I raised the ServerLimit number (apache) to allow for more connections, I also raised the max conncetions in my.cnf. I do not know if this took effect? That should have worked. But basically in phpmyadmin i get this error frequently. I am getting more traffic so I think it is that.

MySQL said: Documentation
#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)

I was wondering if any one can help me out, I am literally tearing my
hair out with an availability search I have written.

Previously I was selecting all the records from two databases but
noticed the response time was very slow anything up to 20 secs.

I tried to streamline the search by only selecting the columns I
needed from the tables and created indexes for each of the tables for
the required rows but now the results are executing in around 50 - 60
secs, which is ultimately alot slower.

The SQL query I am using at the moment is this:

SELECT villas.id, villas.resort, villas.beds, villas.owner,
villas.air_con, villas.walk_beach, villas.walk_shop, pricing.id,
pricing.week, pricing.price, pricing.availability FROM villas LEFT
OUTER JOIN pricing ON villas.id = pricing.id WHERE pricing.week =
1073088000 AND pricing.availability = 1 AND villas.beds > 0 AND
pricing.price > 0 AND ( villas.resort = 'cala_dor' OR villas.resort =
'pollenca' ) GROUP BY villas.id ORDER BY villas.owner DESC ,
villas.beds ASC

I am running the Apache web server, MySQL v4, and PHP on an NT4 server.
Apache runs great, but the auction software I am using (Web2035 Auction
software written in PHP) is very, very slow.

Sometimes it takes 20-30 seconds to bring up an auction page from the items
table which has less than 200 records in it.

Can anyone can give me some pointers on where to start looking? (I don't
know if the bottleneck is with MySQL or PHP or what I might need to look at
to enhance the performance of either package.)

It just seems that my system is slow, adding records, etc. I tried to optimize it, saw that there was a my-medium.ini file, read that is was for medium sized system. I replaced it with my.ini (yes I did make a backup, thankfully) and restarted mysql.

Pretty much it hangs. I tried to connect with QueryBrower, did a Select Count(*) and just froze. I admit that I didn't wait for ever, yes I know I Select Count(*) takes a long time but I gave up after waiting 3x as long as I normal did. Also the logs screen froze in administrator.

I have the following INSERT SQL, which runs very slow (For 2 full days it had not done anything) on a 2 processor Compaq machine running Suse Linux. Code:

I'm hoping someone may have an idea what could be causing the slow loading pages of my web-site. I'm not positive, but I'm relatively sure that it's related to a problem with MySQL database.

I purchased a program called Sam3 for broadcasting our radio signal over the internet. The software requires the use of MySql in order to set up web pages for our web site.

The problem is, that while everything works GREAT (requests can be made from the site, songs can be searched, the history of what we've played shows up) the pages load PAINFULLY slow. Other users of this software have had no such problems so I'm at a loss.

I know from testing that the PHP script for the web pages is fine, I have plenty of bandwith both upload and download available on my DSL line, and while the computer running MySQL is behind a router I have tried plugging the DSL line DIRECTLY into the host computer and it makes no difference.

For all appearances it seems the problem is that it takes MySQL forever to gather and provide the information needed for these pages. Does anyone have any idea what I should be looking at to solve this problem?

I do not know the MySQL program at all, so I get somewhat lost when people start throwing out technical terms, but this has been really frustrating because no one else seems to have the problem and everyone so far has just told me to check the things I've already checked.

I have been developing an application in Visual Basic that accesses a MySQL database either on the local machine, or a remote machine. Locally, database connections run smoothly. However, when I try to connect to the remote system (another computer on my local network) some databases take longer to connect than others (sometimes 10 - 20 seconds).

The application usses the myvbql.dll (sorry lost the link, found it through google) wrapper around the libmysql.dll file to perform database actions. The application seems to hang when it tries to actually make the connection to the datatbase. This is only happening on the remote database server, and does not happen on every connection to that server.

I have a sql table with more then 20,000 rows in a table called summary and when I run "select * from summary" it returns a exucutions time of 0.5 seconds in php which is kinda slow if you ask me, now I know that the * type for select isnt the fastest way to fetch data but its the most convenient for me.

I have a website on a dedicated server that was running really slow, so I got another, much faster server and transferred the MySQL database to this server. However, now when I connect to the faster server's database using the slower server's PHP web pages, the overall page loads much slower than when the database was on the slower server.

Any ideas why this would be? Right now the host name is just an IP address. Does it need an actual resolved hostname to be fast? MySQL on the faster server is supposedly tweaked for fast service (my-huge.cnf).

I installed mysql 5.0 and need to set up slow-query-log and other logging options.

Here is what I did. But I dont see it working yet.

1. cd /var/db/mysql
2. chown mysql slowquery.log
3. touch /usr/local/etc/my.cnf
4. chown mysql /usr/local/etc/my.cnf

vi my.cnf

[mysqld_safe]
-u mysql
--log-slow-queries=/var/db/mysql/slowquery.log

so now when I type:

mysqladmin shutdown
and than

mysqld_safe &
my sql restarts but the log files are not being used.
also - how do I know if my my.cnf is being used at all?

I recently upgraded mysql from 3.23 to 4.0 and found that my websites using the mysql db had a 5 second delay, or latency. I searched for 2 days and found no answer to my latency problem until just a moment ago. I'd like to share the answer in case someone else finds this occurring to them as well.

I was using my real static ip in my website mysql address instead of 'localhost', localhost should have been used initially anyways. I am not real sure what my reasoning was when I initially chose to put in my static IP.

So, If you are like me and keep your stuff on your local machine, use 'localhost' instead of your static IP. At least it fixed my delay issues.

I have MySQL 5 running on a PC, and have grown used to the startling slowness of MySQL joins. The most recent disappointment is a straightforward self-join of a not-too-big (700K rows), indexed (on very-high-cardinality column FILE) table

create table temp2 as
select a.*, b.time as time2,
from temp1 a left join temp1 b
on a.file = b.file
and timestampdiff(HOUR,a.time,b.time) = 1;

that completed in 10 hours. (Indexing resulting table took 20 minutes). If this is not a problem with the programmer, or with MySQL, could it be a result of a mismanaged installation, one that could be fixed with a judicious re-configuration/choice of MySQL options?

I am using the MySQL ODBC 3.51 driver to link three relatively small MySQL
tables to a Microsoft Access 2003 database. I am finding that the data from
the MySQL tables takes a hell of a long time to load making any kind linkage
with my Access data virtually useless.

I have the MySQL driver setup in as a USER DSN. The MySQL data is sitting
out on a server and the Access database is running locally.

I've been sent a dump of a database and am trying to restore it with the
command in the subject line. It's progressing, but very slowly. The
problem is that the database is 40GB.

Now if mysql is doing database-y thing like allowing access while building
tables this might be slowing it a little. Is this the case and is there any way
round the problem and slurp the the whole thing in isolation.

Background: debian sarge

mysql-server-4 4.1.11a-4sarge

I really *am* a mysql newbie - tell me I'm silly for starting at 40GB

I have installed my MySQL Server in a Window XP platform running in a Pentium4 machine. When I access the database on the machine, it is working in a normal speed. But when I access the database from a client machine (still running in windows platform), it runs very slow.

For whatever reason, MySQL does not seem to be executing. So, I ran a few stat functions and here is what I got:

Uptime: 220372
Threads: 39
Questions: 18748899
Slow queries: 808
Opens: 28723
Flush tables: 1
Open tables: 4096
Queries per second avg: 85.078

The "open tables" worries me for a few reasons. First, because it is 4kb (exactly, since it is divisible by 1024, evenly). This makes me think that maybe I am hitting a ceiling.

Second, there are a few variables in MySQL that equal this, and maybe it's a cap on something. Here are the variables that equal 4096:
query_cache_min_res_unit = 4096
table_cache = 4096
transaction_prealloc_size = 4096

Do any of those have anything to do with this? Am I even close? Are any of those values from mysql_stat a big deal?

I have the following MySQL query, but it is VERY VERY slow and seems to be crashing the server. There are 300,000+ records in the 'tracker' table.

SELECT sites.*, SUM(if(tracker.type='view',1,0)) AS numberOfViews, SUM(if(tracker.type='click',1,0)) AS numberOfClicks, SUM(tracker.revenue) AS totalRevenue FROM sites LEFT JOIN tracker ON tracker.site_id = sites.id GROUP BY sites.id ORDER BY sites.domain_name

I have installed MySQL 3.53 on two RH7.3 and one RH9.0 boxes.
On one of the 7.3 and the 9.0 box, when I try to connect remotely, it
takes about 45 seconds to connect, whereas the other 7.3 box connects
almost immediately.

The fast box has standard install of 7.3 with tomcat added.
The 9.0 box is straight RH9.0 standard install.

I can't find anything in common between the slow boxes, but not on the
fast one.

I'm having a problem with a new machine running Mysql version 4.0.18
on the AMD64 version of Mandrake 10.0. The new machine has got 64bit
AMD processor and 2GB of RAM.

Nearly all queries(updates are especially slow) are running 20/30 or
more times slower than on an inferior(32 bit processor, 1.5GB RAM)
machine runnning Mysql 3.23.56 on mandrake 9.0.

As far as I can tell mysql is configured correctly for the power of
the machine. The my.cnf file looks like this: Code:

Yesterday I have upgraded my linux box with a pair of Xeon 1G CPU and
reinstalled everything (it was a sinle Xeon 700). The default RH9
installation comes with MySQL 3.23.54. After the reinstallation I
found the machine was not as responsive as before. (It's not very
slow, but some lagging is noticed)

I was running Mysql-max 4.0.11 and the performance was ok, except the
slowness during the peak hours, which was regarded as normal. I would
like to know the differences between Mysql 3 and 4. Is the new version
making a significant jump in performance?

I also noticed the system eats up memory faster than before. With the
old setting the system never used up 60% of physical memory, even at
extremely high loading (30+). Now it easily used up 70% of memory.

The server is running Mysql only. It's equipped with 2 Xeon 1G and 2G
of memory. The kernel version is 2.4.20-8smp #1 SMP. Also attached the
my.cnf for a clearer picture: Code:

I was running a PHP/MySQL web site with the database on the local web server. I needed to move the database off the webserver (located in the firewall DMZ) and onto its own machine (behind the firewall on our private network)

Now when I run my web site it goes really slow. I ran mysql from the command line on the web server and connected through to the database machine behind the firewall using
webserver:/# mysql -h 192.168.1.7 -u www-data -p

After I enter the password, it takes around 5-7s before I see the mysql> prompt.

Is mysql trying to do reverse dns on the IP address and timing out? I added the machine details to /etc/hosts so it would be recognized but no improvement. Or do I have something wrong with my mysql configuration?
