MYSQL :: MySQL Slow: Configuration To Blame/fix?

Configuration Of MySQL
Everytime I start a new session of MySQL, it prompts me for my password and then boots me out. After I go through the "MySQL Server Instance Config Wizard" and reconfigure everything and reset my password, MySQL lets me back in. Is there anyway to fix it so I don't have to reconfigure everything?

MySQL Configuration
I have recently installed the MySQL5 on my Windows XP. When I try to configure it using the provided configuration wizard, at the last stage "Apply security setting" it gives me the following error:
Quote: The security settings could not be applied.
Error Number 1045.
Access denied for user 'root'@'localhost'(using password:YES)

Problem With MySQL Configuration On IIS With PHP
Everytime I try to read from any MySql database in PHP, I get a blank screen or just a blank response.

I dunno what the problem is. is it the configuration?

When i use phpinfo(), MySql has its own section, which is shown. doesn't this mean it has been configured already?

I have done the configuration of the php.ini file and have removed the quotes before the mysql extensions. I have also included my c:php directory to the path section of my environment variables in control panel and copied libmysql.dll to my windows directory. I just can't seem to get around this problem.

I don't think its my code because i have literally copied code listings from this site and pasted them as trials but still the same thing.

I would appreciate something like a checklist for configuring mysql to work with iis and php to confirm my configuration.

Mysql Configuration File
I just installed a Mysql server version 4.1. I'm trying to set up replication between two servers. The instructions ask me to modify the my.cnf or my.ini file, but there's no such file in my computer.

MySQL Configuration Error
I am trying to get MySQL set up on my Windows server.
The server is running Windows 2003 Server Enterprise Edition and IIS 6.0

I have installed MySQL successfuly but run into problems when configuring it. I get all the way to the Start Server page and click execute.

When I do this I get a tick in the Prepare COnfig and Write Config File boxes but then when it tries to start the server it comes up with the error:
'Could not start the service MySQL' .

PHP5 MySql 4.1 IIS 5.O Configuration Error.
Finally, I decided to go fully into PHP. I downloaded PHP 5 on the PHP site. I also downloaded MySQL 4.1. I'm running IIS on a WinXP professional (SP2) machine. I installed both according to instructions. Tested PHP, it worked fine. Tested MySQL through command prompt and it also worked fine. Now my problem came when trying to get PHP to use MySQL, I got this error
Warning: PHP Startup: Unable to load dynamic library 'c:/php/ext/php_mysql.dll' - The specified procedure could not be found. in Unknown on line 0
I googled and discovered this situation was common all over the internet. It looks like it's peculiar to PHP5. I tried all solutions I saw but none worked. I copied all the relevant dlls to C/winnt and C/winnt/system32 as well as uncommenting the path variable in PHP.ini Still,

JNDI Datasource Configuration Fo MySQL 4.1
I am now in charge of of Java web application that is hitting a MySql database version 3.1. We are in the process of setting up a new box with MySql 4.1. The developer who wrote the application is using technology from the Apache foundation to connect to the database via jsp's (ie. no struts). The technology is referred to as Database Connection Pool Configuration.

Configuration Of MySQL - ORDER BY Clause Problems
Edit:
Solved! Single quotes around the column name were the problem... red herring... didn't spawn an error, probably because single quotes would be valid for an alias?

Anyway, for reference there must be a MySQL setting that tells MySQL to ignore the single quotes in an ORDER BY clause and call the column if there's no matching alias. If anyone knows what *that* setting is, I'm still interested...

I'm stumped! A simple PHP application with a filter using ORDER BY has been moved from a remote server on to a local Debian (Etch) machine running XAMPP. On the remote server it worked fine. On the local server the ORDER BY is ignored. It looks like this:

SELECT *
FROM contacts
WHERE Forenames REGEXP '^{name}'
ORDER BY '{column_name}'
Where {name} is user entered data and {column_name} is determined by which column header in the returned data was clicked in the interface. For example:

SELECT *
FROM contacts
WHERE Forenames REGEXP '^Jake'
ORDER BY 'Company'
As I say, this *was* fine... but now on the local machine the ORDER BY is totally ignored by MySQL. I know the problem is with MySQL because I get the same result in the MySQL Query Analyser, so it's not a PHP/Apache issue.

Is there a config option for switching ORDER BY on/off like there is in MS Access? I'm 99% sure this is a MySQL config problem...

MySQL Server Instance Configuration Installation
Hi everyone. I just tried installing MySQL Community Edition, but it has frozen up during the final step (MySQL Server Instance Configuration). I'm installing it on Windows XP, and I used all the default settings, except that I changed "Detailed Configuration" to "Standard Configuration". The installation window now says "Not Responding" and I don't know what to do. I guess if I shut it down manually, MySQL won't be configured properly. I don't know if this will corrupt the installation, or if the installation part has already finished.

MySQL Server Instance Configuration Wizard
I just downloaded and installed MySQL 5.0 on a P4, Windows XP Pro system and followed the Server Instance Configuration Wizard. Once I have selected the default settings, and clicked Execute, I get an error message

Cannot create Windows service for MySQL. Error: 0

MySQL 4.0.18 InnoDB Configuration Issues On SuSE 9.1 Pro
I've tried resolving this issue in a SuSE newsgroup, but after trying
their suggestions and working on this issue for far too long already, I
decided to try this list as it may be a more appropriate discussion area.

I've installed and configured MySQL 4.0.18 on a SuSE 9.1 system using
the default RPM's that came with the distribution.

I created a simple database (one table with InnoDB engine type) and have
tried running some ODBC source against it to test transactions, but I
get the error that the server does not have transactions enabled.

I was directed to enable transactions in the configuration file
(/etc/my.cnf) by uncommenting the lines for innoDb use. However, after
uncommenting these lines and running mysqld from the commandline
(according the online Manual), to generate InnoDB support tables, I get
the following error:

mysqld: ERROR: unknown variable 'innodb_data_home_dir=/var/lib/mysql/'

I've tried removing the RPM's and starting from scratch, but cannot get
past this error and successfully test transactions in my unit tests.

MySQL Entry Level Server Hardware Configuration
We have a web site statistics database running on a dedicated PC (P4 1GB RAM, 1xSATA, Windows Xp 32 bit). It's updated daily and used by a single user to get some reports. While it's mostly SELECTs, some temporary tables can be built.

As the database get bigger and bigger (few gigabytes), it works slower and slower. Currently the HDD is the bottleneck, but the PC is not upgradeable, so I'll have to build a new server. Reliability is NOT #1 in my list, while the speed is - it'd be easier (and chipper) for me to copy the data across rather than to build a 4+ dsik monsters.

What would be the suggestions for hardware and OS? Or may be a URL to detailed review?

MySQL Slow
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.

MySQL Very Slow.
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++;
}

Why Does MySQL So Slow
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.

MySQL Slow Log
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??

Slow MySQL
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)

Slow Response From MySQL
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

MySQL Slow In Windows NT4
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.)

MySQL Is Slow, Trying To Optimize
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.

MySQL Slow Starting Up
I am using a Windows 2003 Web Edition Server running IIS and MySQL 4.1. I had to restart the server the other day and it took MySQL almost 2 hours to come back up. I was watching it on my task manager and it went up to approximately 60,000k in 10k increments before I was able to access MySQL.

My CPU usage was hovering around 3% all this time. Everything else came up on the server just fine. This happens every time I have to restart my server. The reason I have to restart my server most of the time, is because MySQL locks up on me.

Is there any settings I can change that would help me here? Any help would be greatly appreciated.

One more thing to add. I am using the default my.ini file. We have almost 100 different databases on the server and have around 20000 tables within all of these databases combined. All of these tables are InnoDB tables.

MySQL Running Very Slow
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:

Slow Running MySQL?
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.

MySQL Connection Sometimes Slow
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.

Slow Mysql Select *,
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.

Remote MySQL Connection Slow
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).

Mysql 5.0 - Using My.cnf - Unix / Slow-query-log
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?

Delay, Latency, Slow Mysql
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.

MySQL ODBC 3.51 Driver Very Slow!
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.

Mysql -s -u Root Bmd < Db.dump2 Slow
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

My MySQL Back-end Works Very Slow
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.

MySQL Timing Out? Really Slow Queries, Already Indexed.
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?

VER VERY VERY Slow MySQL Query HELP URGENTLY NEEDED
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

MySQL Redhat Slow Responding To Connections
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.

Mysql Running Slow On Mandrake Linux 10.0 For AMD 64
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:

Slow Performance After Falling Back To MySQL 3
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:

MySQL Slow To Connect To Remote Database
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?

MySQL Slow With 4GB Memory - Tuning Required?
I am using MySQL 4.1 on Linux (IBM Open Power Server). The Server has 4GB memory, 380GB hard drive.

I have a Java based application that runs in Tomcat in a Windows environment using SQL Server. As part of a customer project I have got the application to work on Tomcat on Linux with MySQL.

Both databases have a large amount of data in some of the tables, e.g. 500,000+ records in some of the tables. Some of the tables have indexes on them.

There is a specifc part of the application that is slow when running against MySQL (10 seconds to write a record to a table with 500,000+ records in it.) The same bit of functionality running against SQL Server is instance, e.g. 2 secomds max. The code is doing an insert statement. Once the insert has taken place we need to get the ID for the inserted record. This is using SELECT MAX....... The ID column is set as the Primary Key and is indexed. Code:

User Admin In Mysql-administrator Slow On Linux
We have a MySQL 5.0.16 server installed on a RedHat 8.0 machine.
mysql-administrator v1.0.22 is installed on RH Linux FC3 from the
mysql-administrator-1.0.22a-1.rh9.i386.rpm.

Everything seems to run fine except User Administration is *extremely*
slow. If I click on "User Administration" in the sidebar, it takes
about 2 minutes (seems like forever) before the window comes back with
the infomation. All the other functions seem to function fine.

Is it because I'm using mysql-administrator on a remote host? Do I need
to move and rebuild the server to a newer Linux version? mysqlcc
doesn't have this problem at all. (It's using the libraries from MySQL
4.1 that the databases were migrated to.)

What Will Be The Best My.cnf Configuration?
I have a MySQL 5.0.27-standard-log slave server running on a server with

Processor: Dual Xeon E5372 Quad Core (Clovertown)
RAM 12GB
Hd1: 120GB
OS: Linux - CentOS 4

I have 15GB+ data with MyISAM and InnoDB tables. InnoDB tables are not in much use, we perform user searches on MyISAM tables which have FULLTEXT.

Question: What will be the best my.cnf configuration? Below is the current my.cnf ....
