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 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 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.

Remote Connection To MySQL
Trying to connect to a MySQL server from my desktop.

Specs:

My Desktop - XP OS - MySQL Administrator.
Server - Red Hat Linus OS - MySQL version 4.x

From the MySQL I am getting an error code 2003 "Can't connect to MySQL server (10060)".  I am using the default port 3006.

Any suggestions?  What additional information do you need to help me out here?

MySql Remote Connection
I'm having problems in trying to remote connect to a database and it's driving me nuts.

Database is on server, trying to connect to it through internet using MySQL Control Center with following settings:

Name: Lucca
HostName: IP address of server
UserName: Beeps
Password: """"
Port: 3306

I've made sure that the firewall will allow entry and can successfully ping the server, but I get the following error:

Error 2003: Can't connect to MySQL server on "ip" (10060)

Remote MySQL Connection Fails
I have two XP computers, with the same version of MySQL on each. I
have the same database structure and data on each. Each computer has
the same user name, and each MySQL database has the same user names.
Locally on each, I can connect and work with the data. I can ping
each computer from the other computer. My problem is that when I try
to connect from one computer to the other I get the following error:
Host 'XXX.XXX.XX.XX' is not allowed to connect to this MySQL server.
This happens on both computers. I can not find the reason for the
error.

Remote Connection To Mysql Database Using JDBC?
I am trying to set up OpenOffice Base to connect to a remote os x server with mysql on it.

It has the default mySQL JDBC driver class set to com.mysql.jdbc.Driver

It also asks for server URL, should this be the ip address?
Port number? Default is set to 3306.

When I set the class it says that the JDBC driver could not be loaded.

Remote Connection To MySQL DB Server From Client With No MySQL DB
I have MySQL server running on a Solaris machine. I have a Perl tool that is run on multiple operating systems (Linux, Solaris, MKS on windows, CYGWIN on windows). I would like to post to the MySQL database on the Solaris machine from this script when it is run on the different local clients. All these clients share a single network share (available via Samba on windows).

Is there a Perl module that I can install in the network share that I can use to connect remotely to the server DB?

Slow Connection
I build an application and installed it on many machines. In every machine except two, the program works without problems. On this two, the connection with database is too slow.

I saw the opened doors with 'netstat' and the computer opens about 5 or 6 ports (to the port 3306 of the mysql server) before sucessfuly connect with MySql Database and execute the sql. I don't know what could be happening. I realy need to fix this because the progrm is too slow with this error. Could anyone know what could be happening??

Remote SQL Connection
I am trying to access my database on the server with a MYSQL front-end
client on my computer (not the server). I have the correct username,
password and database name. I tried every possible hostname, even its ip
addy, but each time, I am rejected by the server, which says something
like - access denied. I can access the database in my php code with
'localhost', but that's of course because the code is actually running on
the server. Is there anything I have to specify on the MYSQL server in order
to gain access to it remotely?

Remote Connection
First of all hey guys i'm new to this forum and hope to get some help on getting me fully started with mySQL.

Alrite i've really briefly used mySQL with java but only with a local database.

I need help on how to create remote connections via the internet to mySQL. Basically i've been trying to test out connecting via the internet from my home machine where mySQL is installed, i've tried this through windows command line and doing:

mysql -h myip -u myuser -p

also tried with --port=3306

but it doesn't work. Does the fact that i'm behind a router and have a different local ip matter? Or does the fact that i'm doing this from the machine that holds the mySQL database but i'm using the internet IP address to make it go through the internet. I've already opened up the port in my routers firewall.

I wanted to create a java application that can access a mySQL database over the internet so I thought i'd try out remote connections on windows command line first.

I'm very new to mySQL so any help in the right direction and/or what i'm doing wrong with some explanation will help me give a better understanding.

Remote Connection
just that. and DONOT point me to any documentation ive been through it all mysql will NOT let me give any host persmissions it keeps giving me the syntax crap and to check the menual when i did it just like the friggen manual said

GRANT ALL PRIVILEGES TO db.*
-> root@'host';

and its really pissing me off.
im runing mysql 4.1.8 any ideas?
i also put the host in my hosts file and still nogo

Remote Connection
I'm having a problem connecting to mysql on a remote host because it truncates my user name (dbm.stetsonband.org):

ERROR 1045 (00000): Access denied for user: 'dbm.stetsonband.@d199-126-224-237.abhsia.telus.net' (Using password: YES)

Is there something I need to set in my mysql prefs somewhere?

Remote Connection Through Php Script
I have a mysql server running at the office on <officeip>:3306

I have a site hosted by a provider at domain.it

I have granted privileges for existing user office as office@domain.it and office@domainip

I wrote a php script using the parameters:

$host='<officeip>'

$user=office

$pass='<thepass>'

$db='<mydb>'

to connect to the office db from the website.

I get a 'Lost connection' error (no query to execute just connecting so no time-out problem)

What do you believe is wrong with it?

Remote Connection To Sql Server
I've set the remote website, dotbooks.org (207.44.234.74) as an "Access Host" in cPanel.

I'm trying to connect to wiishare.org (70.86.206.218)

The connection string I'm trying is:

<?php

$user = "username";
$password = "password";
$database = "database";

$link = mysql_connect("70.86.206.218", $user, $password);
mysql_select_db($database, $link);
echo mysql_errno($link) . ": " . mysql_error($link). "
";
?>

The string works with localhost, but not like this. It just times out

Establishing A Remote Connection
I'm trying to enable remote connections to my mysql database. I'm getting a
java.sql.SQLException: Unable to connect to any hosts due to exception: java.net.ConnectException: Connection refused

error when I try establish a jdbc connection. I'm supplying the correct user/pass information.

A quick google tells me that I need to enable connections from places other than localhost.
okay, so I do a:

mysql> GRANT ALL PRIVILEGES ON *.* to raghav@'%' identified by 'blah';

As can be seen from the table below, i've tried doing it for anonymous accounts as well, when all of this didn't work. I've flushed privileges, and restarted the mysql server. no luck. Code:

Query Browser When Opened Via Remote Desktop Connection
I have a MySQL database that I set up by running a couple of .sql scripts.

The .sql files are fine and not corrupted.

But they are located on our server in headoffice.  When I try to open them in MySQL Query Browser (also installed on the headoffice server) via Remote Desktop Connection, the Query Browser opens a new script tab but does not display anything (i.e. no text in the scipt tab).

Also, I'm sure this is related, I can enter a query in to the execute box and execute it, but you cannot see the text as it is being typed.  However it is there as when I click the Execute button the query runs fine.

Any ideas why I am not able to see any entered text in the Query Browser window?  I have tried uninstalling and reinstalling Query Browser a few times, but this has not cured the problem.

MySQL Remote Backups - No Access To FTP Or Remote Command Line
I have a mySQL database located on a remote host's server. I would
like to schedule a task on my local Windows computer to retrieve a
backup/dump of this remote database.

I have contacted my host, and they indicated that the server is only
open to the Internet via mySQL. Therefore, even if I did have access
to that server's command line (which I don't) to create dumps via
mysqldump, I would not be able to retrieve via FTP.

Does anybody have any ideas as to how I can generate backup files from
my local computer through a local command-line interface? I have done
it through a GUI (DBTools), but I would like to have it done via DOS
batch, so that I can schedule it. Does anyone know of any mysql backup
GUIs with command line switches? Or can somebody recommend an
alternate means of getting a local backup?

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.

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.

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 Slow: Configuration To Blame/fix?
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?

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 &lt; 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

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)

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