Optimizing MySQL
Aug 12, 2007i run a popular forum with at least 1000-1200 users online at any given time which reaches 2000-2500 at peak times...
i am using Invision Power Board.
Problem:
Server seems to lose connection with mysql server at peak loads with server load going upto 30.
The server is good enough for these type of loads...
Server Specs:
Code:
Dual AMD Opteron 248
4 GB RAM
CENTOS Enterprise 4.5 i686
Cpanel
The my.cnf file is as follows:

any changes that would bring down the server load?
Also, some entries from httpd.conf are as follows:

Optimizing Large MySQL Table
Nov 2, 2009I optimized a mysql table of 2 million records and about 500MB.. it took about 15 minutes.. However, on the same DB now i have another huge table of 88 million records, it size is 2.2 GB and it has about 30 MB to optimize... my questions..
1.- How can I speed up the optimization process so it can take the less possible time? any tweaks to my.cnf?
2.- Should I repair it using phpmyadmin or just from the shell?
3.- Should I stop http traffic during this optimization?
This is a dedicated db mysql server that handles a large VB forum with 5-8 users online average:

Optimizing MySQL On A Busy Server (4 Gigs Of Ram)
Dec 8, 2008it's getting to the point where I need to optimize MySQL to better handle a busy server.
These days it seems MySQL is using 30% - 60% CPU almost constantly. But, the good news is that I've got 4 gigs of ram on this box and their seems to be an access of 600mb free constantly throughout the day.
Is it possible to tweak MySQL to a little more RAM dependent and take some of the load off the CPU? It seems MySQL wont go over 300mb of ram at any given time.. I'm already working on optimizing the SQL Querys on the web page itself.
my.cnf (4.1.22-standard):
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
# old_passwords=1
# [mysql.server]
# user=mysql

Optimizing These Particular MySQL Slow Queries In WordPress
Jun 14, 2008What I did here was create /var/log/mysqld.slow.log for queries that are taking one second or longer. After around 36 hours, here is what I came up with. Since the file size of /var/log/mysqld.slow.log was 219KB, posting it in its entirety it not practical. Therefore, I used a program, the perl script known as mysql_slow_log_parser found on www.retards.org, to parse the mysqld.slow.log to make it easier to interpret and read. The result was that the original filesize of 219KB was converted to the smaller size of 14KB....

May 11, 2009Are there any services where an ADMIN can monitor DB usage on system and make some recommendations or even find SQL that is poorly written ...
I have a DUAL harpertown, 10GB RAM, and RAID
I have a typical, gallery, busy VB forum, and video script...
THe site traffic has not increased much but my Memory keeps getting chewed up... i already did some tuning that VBULLLETIN suggested... but the memory still goes... i need a tool or someone to just monitor the server for a day and grab as much diagnostic info as possible..
I suspect that its a single query giving problems cuz i have some custom coded pages...
I don't want to split the DB and HTTP request on diff servers cuz the traffic that i get shouldn't warrant it... for now...
VPS Optimizing
Feb 13, 2007I have a 512mb cPanel VPS and would like to try and save a bit more ram, I have made the below changes to the httpd.conf and have also turned spamd, entropychat, melange, mailman, the only webstats I have is AWStats
Code:
MinSpareServers 2
MaxSpareServers 5
StartServers 3
Can anyone recommend any other changes to save some more ram ?
For anyone wanting to know, the VPS is being used to serve my websites
Optimizing Apache
Jun 27, 2008I have a server facing to 150+ requests/sec. Using apache 1.3.39. The current config here

KeepAliveTimeout 5
MinSpareServers 15
MaxSpareServers 20

I wonder if I can change anything to make site is faster? Currently, it's very slow. It's one core2duo box with 2GB RAM
Optimizing A VPS Server
Sep 6, 2008A friend of mine has a VPS server from godaddy, the site he is hosting on this VPS is quite slow and times out a lot.
What would be the best option? Move out of godaddy? Upgrade the plan? or hire someone to optimize the server (apache/mysql).
If you would recommend the third option, it would be great if you can let me know about companies that provide this service.
Optimizing Httpd.conf...
May 26, 2008I remember seeing a website/forum where you couldn't post your server stats and httpd.conf settings and experts would give advice on settings you should use.
Does anyone know the url to this site, or site similar to it
Optimizing Dedicated Server
May 24, 2007Are there some simple things that we can do or perhaps request our server management to do to optimize our server? Not sure where to start or what to ask so would like to learn some more before speaking with the server management company. Often times, you need to know the right questions to ask.

Apache Goes Down + Optimizing Dedicated Server
Oct 4, 2007I am having problems with apache going down at least once a day. In Plesk there is a watchdog that monitors the service and then restarts it, but tries 5 times and fails, so apache will still be down and monitoring released. I really don't know what is causing this problem, maybe I could get some help? (Server specs at bottom of post, hope this is all you need)

Optimizing Server For Proxy Hosting
Mar 21, 2007i have a Pentium D 820, 2GB Ram at LT where i am hosting a few proxies. Using Centos and Directadmin.
It's realy fast and i am happy with it. The only problem i am facing is that load is jumping up to 60 sometimes but just for a few seconds. Especially when a lot of people are using the proxy and it slows down a bit. That affects only the proxified pages and not a few personal html sites i also host there.
At the moment i am seeing in top that the CPU usage varies from 0,2 to 8, 12, 21 etc but just for a second or two
here is the top output
Quote:
[root@server ~]# top
top - 12:46:18 up 23 days, 2:36, 1 user, load average: 0.36, 0.44, 0.29

and another output

and the number of connections on port 80

[root@server ~]#
is there any way to tweak or optimize the server so than it can cope better when a lot of people are using the proxy.

Optimizing Lighttpd For Large Files (180mb Avg)
May 9, 2008I have four servers with a quad xeon, 4gb ram, and 2x300GB SAS 15K RAID0 harddrives, pushing a total of 1.6gbits. It serves a lot of zip files with an average flesize of 180mb. My question is, how can I optimize lighttpd 1.4.19 to push its max with very low IO-wait. I've looked up some stuff and only found options that deal with lighttpd 1.5 and use Linux-AIO for the backend network. Currently I use writev with 16 workers and an read/write idle timeout of 10s. Logging is off, too.

Jul 7, 2008I am running a SQL test server here that is piping HUGE amounts of data for a test project I am running.
Approximately 30 queries a second - constantly. That's over 2.5M queries a day -- so we are talking big (I think?)
I am currently running this test on a
AMD Phenom 9300, 4GB RAM - SATA 500GB HDD and I am running MySQL 5.0.51a i386 on CentOS
I have programmed a process control for our applications purpose - basically it controls the launching of our SQL intense applications, and stops launching when the Load is greater than 2.5
I have plans to optimize the number of queries (I will build in a cache to some of the applications - and run INSERT statements all together) however I am looking for SQL tweaks that will improve performance. Would running the 64bit version work better?

Installed MySQL In /usr/local/mysql But Error In /var/lib/mysql
Jan 21, 2007I installed the MySQL binary packages in /usr/local/mysql/ after removing the MySQL RPM package. MySQL is functioning when I executed /usr/local/mysql/bin/safe_mysqld. I reinstalled MySQL before I installed PHP. When I used a PHP script to access a MySQL database, it outputs an error:
Code:
Warning: mysqli::mysqli() [function.mysqli-mysqli]: (HY000/2002): can't connect to local mysql server through socket /var/lib/mysql/mysql.sock in index.php on line 2
However, I installed MySQL in /usr/local/mysql, not in /var/lib/mysql. How do I fix MySQL?

View 5 Replies View RelatedHow To Restore Mysql Databases From /var/lib/mysql/user_database/ Files Only
Feb 11, 2008I recently had a harddrive failure and luckliy I can still access certain directories on this failed drive. I can still access the /var/lib/mysql/ directory which holds all the users databases and have backed all these up separately using tar.
Now what I need to know is how do you restore these database files to another server? I tried simply untar'ing one of these to the new servers /var/lib/mysql/ direcotry and it stuffed Mysql up - it went offline. I had to get a cpanel tech to bring Mysql back online.
how can I get these database files to fully work on a new server?

View 5 Replies View RelatedMySQL Monitor Shows MySQL As Offline When It's Not
Jan 15, 2007I've been racking my brains with this problem for the last couple of months and have made zero progress. I've asked a lot of people if they know what might be wrong here, but none of them have any idea.
Basically, the problem is that any sort of service monitor I put on my server shows MySQL as being down/offline, even when I know for sure it's up and running perfectly fine. All other services report a green light.
The mysqld service is running on port 3306, which is open both inbound and outbound on my APF config, so as far as I can tell it's nothing to do with the firewall (I won't rule that out though).
The other odd thing is that MySQL shows a green light within WHM, but not anywhere else.
Does anyone know what might be wrong here? Am I missing something entirely fundamental and obvious?

Uninstall MySQL 3.23 And Install MySQL 5.0
Mar 28, 2007I've rented a dedicated server that comes with Red Hat Enterprise Linux 4 and MySQL 3.23 but I need at least MySQL 4.1 or higher. My knowledge about GNU/Linux is very limited, so I've read some documents at mysql.com and now I think I have to follow these steps:
1. Uninstall MySQL 3.23 with this command line:
shell> rpm -e mysql-*.rpm
2. Install the server and client RPMs of MySQL 5.0:
shell> rpm -i MySQL-server-VERSION.i386.rpm
shell> rpm -i MySQL-client-VERSION.i386.rpm

Upgrade From MySQL 4 To MySQL 5
Jun 3, 2008I'm trying to upgrade from MySQL 4 to MySQL 5 for performance reasons. MySQL 4 was working great so I decided to just go ahead and upgrade to MySQL 5 via CPanel. The upgrade appeared to go fine however I now get this error when trying to start MySQL.
/usr/bin/mysqladmin: connect to server at 'localhost' failed error: 'Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)' Check that mysqld is running and that the socket: '/var/lib/mysql/mysql.sock' exists! mysql has failed, please contact the sysadmin (result was "Warning, no valid mysql.sock file found.mysql has failed").
I went ahead and did a forced re-install of MySQL 5, but that didn't help. Apache has been updated as well since then, but that did no good, and the MySQL process isn't starting at all.
Its CENTOS with PHP5.
