Overload- MySQL
My webserver keeps on overloading, causing pages to lag and mysql connections to get clogged. Each time it overloads, it's because of there being too many MySQL connections, and I really just don't know why there are so many. I am not sure whether someone is sabotaging my server or whether there is a hole in my php scripts that causes an abundance of connections, or some very slow query.

MySQL Replication For User On Shared Server
I never did replication and do not know much about it so I figured I would ask here if anyone knows or has done it before like this.

I have a user who wants me to enable replication on my server for his user. I dont like the sounds of it on a shared environment but if there is no risk to other users and its not a big resource hog I will do it. Anyway, from what I gather I have to:

1. execute:
GRANT REPLICATION SLAVE ON user_main.* TO 'repl'@'ip-here' IDENTIFIED BY '4T6WjUZa';
[url]

2. Stop mysql server and Add in my.cnf:
[mysqld]
log-bin=mysql-bin
server-id=1
slave-compressed=1
binlog-do-db=user_main
start server[url]

3. execute:
SHOW MASTER STATUS;
we need values of colomns File and Position from output of above command[url]

So my questions are:

Is there any security risk?
Is there significant extra resource usage?
Is this even done on shared environments?

Server Overload Solution
i want to kill apache/http and restart it again automatically. i need this because sometime we are not in front of the server to fix an overload issue immediately, which can affect a server very badly. i believe many of us already face this kind of situation and hope there is some kind of script or way to do this.

Server Overload :: Don't Ignore This Email ... Cpu Has Been Maxed Out For ...
I have been receiving these a couple time a day lately and not sure what to do or how to go about checking what might be overloading the server. IF this looks familiar to anyone, I'd appreciate some helpful tips. I'm still a novice, but can muddle my way around the server if given enough guidance. Here is the email I've been getting:

"IMPORTANT: Do not ignore this email.
This is cPanel stats runner on host.myserverhost.com!
While processing the log files for user xxxxxxx, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is
19:20:10 up 2 days, 7:06, 0 users, load average: 15.17, 13.24, 8.00
You should check the server to see why the load is so high and take steps to lower the load. If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes)."

I guess my question is, how would I go about determining what is causing the excess load? Seems to happen even when not many folks are on my site.

Dedicated Server Overload ... Low Page Views
I'm on a low-end dedicated server that I run 2 decent sized blogs on. I'm getting several traffic spikes a day where the load goes through the roof and I think I need my server optimized.

My server admin says I need a bigger server and he has never steered me wrong but this is ridiculous:

My blogs use Wordpress as its blogging platform....I know they hog server resources and I've recently installed Super cache so that seems to help.

I average about 5,000 pageviews a day and I would think even a low-end box should handle this but maybe I am wrong.

Here's the server specs:

MySQL Forgetting User Permissions
Does anyone know what could be the cause of this issue? I located a few others over at cpanel.net that have this problem, but no solution has been found.

[url]

I am running a VPS server with the following:

WHM 10.8.0 cPanel 10.9.1-S14304
RedHat 9 i686 - WHM X v3.1.0
phpMyAdmin - 2.9.0.2
MySQL client version: 4.1.10
mysql version: 5.0.27-standard

I have a database user that needs "Super Privileges" and so this was done. However, when Cpanel is updated the user permission is reset automatically from "ALL PRIVILEGES" to "USAGE".

Here's a look at the database permissions from phpMyAdmin.

Code:
User Host Password Global privileges Grant
hello localhost Yes ALL PRIVILEGES Yes
hello_ % No ALL PRIVILEGES Yes
hello_ localhost No ALL PRIVILEGES Yes

The user "hello" loses its "ALL PRIVILEGES" and switches over to "USAGE" if an update is triggered. Updates to cpanel, creating/removing a database/user, and updating the account password will cause the switch.

-Select table data
-Insert table data
-Update table data
-Delete table data
-Create tables
-Drop tables
-Grant privileges
-Reference operations
-Manage indexes
-Alter tables
-Create temp tables
-Lock tables

Mysql User Privilege Changed By Cpanel Or What
I am using Cpanel. One Cpanel account is backup. I use it to backup my database.

Under mysql, I gave this account ( backup ) many priviledges. But when the backup script ran, error said that backup account can not 'lock table'.

I gave "lock table' priviledge again and run the script, it is ok.
But after a while, when the script ran autmatically on daily basis, it lost the 'lock table' priviledge again.

I wonder if Cpanel is messing me up? What can I do about it? anyone knows?

MySQL: Access Denied For Root User
When I deleted a database, the user apparently was orphaned because when I tried to recreate it, it returned "user already exists". I've never encountered that problem although from Googling, I see others have and they delete the user to get around it.

When I log into mysql using the da_admin@ account and attempt to remove the user with drop user <user_name>; I receive the following error message:

ERROR 1227 (42000): Access denied; you need the CREATE USER privilege for this operation

It seems I don't have rights even as the root user. How can I get remove the orphaned user?

Weird MySQL: User/pass Stops Working After A While
I am having a very strange problem with 2 different cPanel accounts on a server with 500-600 accounts. For some reason after a day or two the mysql username/password stops working. We have tried changing the MySQL user and the password with no success. The log does not indicate that the MySQL password was changed in any way. Only these 2 accounts are affected and this problem occurred at least half dozen times each.

Again: these are two different accounts with 2 different MySQL users that after a while stop working (I am unable to determine if they stop working at the same time b/c they belong to different customers). When we reset the user (with the same pass) it works for a day or two. I have checked to connect not only from PHP but also from shell when it's down: it also doesn't work so this is a pure MySQL problem.

Also on the server we have Fantastico.

Granting MySQL Command Line Permissions To A User
Is there any safe way to grant command line permissions to a user/specific account? One that only allows them access to databases on their account.

The problem is that this user intermittently runs queries that cause their database to hang (including PHPMyAdmin, so they can't view the processlist through there), and I have to manually kill that process, because they can't.

Server is 2.4.21 with MySQL 4.0.27, admin is cPanel WHM.

Overload Of Traffic
I am not sure if my dedicated server is being attacked or if it is legitimate traffic. I need help figuring out the difference and if it is an attack, how to prevent it, and if it is legitimate traffic, how to configure the server to handle the load.

HardwareIntel Xeon 3220-Quad Core [2.4GHz
8GB DDR2
SATAII 500GB

SoftwareCentOS 5.3-32
Apache2
MySQL 5
PHP 5
When I do ps aux|grep httpd|wc -l I get the count of current connected clients of 259 which is always maxing out my MaxClients of 256. I had increased it to 512, and it maxed out, I had increased it to 1024 and it maxed out, and lastly I had setup to 2048 and it works, but slows the entire server down.

Cpu Overload Warning Mail From Cpanel
i am continously getting warning mail form cpanel cpu watch that my cpu got overloaded as like follows,

IMPORTANT: Do not ignore this email.
This is cPanel cpuwatch on xxx.com!
While processing, the cpu has been
maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of
this email is
19:05:10 up 143 days, 20:38, 0 users, load average: 1.11, 0.69, 0.63
You should check the server to see why the load is so high and take
steps to lower the load. If you want stats to continue to run even with a high load; Edit
/var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run
/usr/local/cpanel/startup afterwards to pickup the changes).

I searched on load average and found that average load for 1 cpu is 2 and default value is 5 to 10.but here i am getting mail for 1.11 itself.I changed the value of threshold of load average in stat and logs of tweak setting to 4.but no improvement.now also i am getting more than 4 mails for average load i.e 1.23 also

My questions are:

1)what is the criteria cpanel is checking for sending cpu-watch warning mail?

2)i am getting nothing more than rsync and exim at the time of overload(while using TOP command).So why now only i am getting warning mail?
what is the cause of this problem?

I was getting idea from internet to create account without stat/ log analyse function .But not sure how will it work and afraid of doing this.......

Single User Can't Access Any Site On My Server
I have a user who says he cannot get to any site on my server from either home or work. He has been a user for many years, and has never had any problems. He has also checked with his IT at work and they confirmed the site is not available. He is computer savvy, so I trust he is telling the truth.

His work and home are only 10 miles apart.

Do you guys have any ideas what could be happening? Is there a DNS entry wrong somewhere? He can't access the site even when putting in the IP address.

There is one other user reporting something similar but other than that no other complaints. The site works fine for everyone else.

site is gm-trucks.com

Monitoring A User's SSH? Also... Mysqld Running At 103%cpu & Stats Overload Emails
I have 3 questions.

1.) I have a user that's kinda knows a lot about linux. More than me. He has a lot of stuff on the system which I have no idea what it is. Is there any way I can install a SSH log, so I can monitor what he does in shell?

2.) My server seems REALLY sluggish. I ran a top in shell, and mysqld was taking up from 70% to 110% of the cpu. Is there any way to fix this or find out why? I've restarted the server, and it's fluctuating between 50% and 90% now.

3.) I think this MIGHT be related to the sqld issue, but I've received about 12 emails saying

This is cPanel stats runner on server1.cewxp.com!

While processing the log files for user cewxp, the cpu has been
