I get this around 50 times a day!
I am fed up!
I saw following error in some of my site in my server.
Coppermine critical error:
Unable to connect to database !

or following error :
Invalid mysql server connection
Please help me how can I resolve this error !

During peak times (especially weekends) many of my site's users have been reporting intermittent 'IPS Driver Errors' in the forums and the following error in the coppermine gallery:
Quote:
Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (11)
(The forums and the gallery are the main parts of the site).
I'm assuming that the site is having problems handling the number of users trying to connect to SQL. I tried increasing the max_connections and max_user_connections settings in my.cnf but it doesn't seem to have made a significant difference.
What do I need to do to fix this? Would I need to upgrade my server specs or is it something to do with the server settings?
my server specs: AMD Dual/Dual Opteron 270 with 4GB RAM.
When i go to my website or any page under the domain it's just white. Blank nothing, nada.
"Failed to receive status information from Apache. Unable to connect to local httpd server."
This error message appears when i click on "apache status".
Is this because of the network issue? Or is it because of something I did myself?
I did a google search and came up on some solution, I did them and nothing.
I am using localhost as mysql server name on my config file. then, when I enter [url], the address will automatically change to[url]that obviously getting error. when I change the mysql server name from localhost to the server public IP, everything seems ok.
My sql is 4.1.x with php 4.4.7, is that any way I may use localhost instead of IP?
or is there any potential danger using IP?
I have a few users that have a hosting account with me and are trying to connect to their own MySQL servers elsewhere. Both said that they are able to connect to the MySQL server with other hosting accounts but not the ones hosted with me. I asked if they had setup permissions to allow remote connections from my server and they confirmed that they did.
What am I missing? Do I need to configure my firewall somehow? I figured the connection is just using port 80 since it's from an PHP script right?
Do you guys know anything about this?
My server works perfectly with INSERT, UPDATE, DELETE for mysql.
but after like 12 hours later, my application crashes and I get this
"Can't connect to MySQL server on 'localhost' (10055)" and I would have to restart my applications and everything will be working perfectly.
Do you guys have any idea why this happen?
I do have a lot of connections coming in and out of my server. Would that mean anything?
Is it possible to make Joomla connect to an external mysql database server?
Meaning, the database for Joomla won't be local, but on another server.
Will it work by just entering the mysql hostname, user and password in Joomla's config?
What issues might arose by doing this?
Somehow when customers add a new MySQL database they can select a Local MySQL server. It turns out this is the MySQL instance running on the CP server, can I somehow hide this server from the list?

I 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?
I started getting small periods of intermittent connection errors about once every hour, lasting for about 1 to 5 minutes each time:
Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock'
I enabled the error log and did some other monitoring and established 2 things:
- the server doesn't crash/restart, it keeps running throughout the errors
- the errors do not match the load on the website, as sometimes when 500 users are online there are no errors, but when 300 are online they may by prolific
I checked many forums and then made 5 changes:
- changed the directory containing the mysql.sock file so only file owners or superusers can delete files from it
- I changed the default socket file setting in both my.cnf and php.ini
- I read about SELinux causing such a problem, so I disabled SELinux completely, rebooted the server and double-checked that it is indeed disabled.
- I changed the maximum amount of open files allowed by the operating system from 1024 to 30000.
Despite all these changes, I still get the errors. I then read that there is a workaround by using TCP/IP instead of the sock file. I tried that, but I still get the error intermittently in the form of:
Can't connect to MySQL server on 127.0.0.1
MySQL server 4.1.20, PHP 4.3.9, client API 4.1.20, CentOS 4.3, Intel P4 2.8GHz 1GB RAM
I am using cPanel 11 (stable release) on a CentOS 5 server and would like to make it so that a certain database can only be connected to from the cPanel user that it is under (ie. user1_db can only be connected to from the user "user1" on the same server).
View 9 Replies View RelatedI got this weird problem with my VPS which has MySQL 4.1.22 running on it. Everything works fine for sometime and then out of a sudden, it stop recognizing the mysql users and refused to allow my PHP scripts to access the database.
It seems that I needed to restart mySQL server to resolve the issue. Then out of the blues, the same problem occurs.
I am running Cpanel on a VPS and there isn't any overloading as the database access is pretty light on my 512mb VPS.
I contacted my web host about the issue and it seems like all they do is to restart the mySQL. This cannot be a solution as it happens at least once or twice a day depending on how soon I could catch the problem.
All the time this problem occurs, the MYSQL Server is still active and working. I can even access it through PHPMyAdmin but not through the scripts.
I just added an hourly crontab so as to restart the MySQL server as a stop gap.
Is there anywhere where I can run a php socket server that is not a dedicated server.
I doubt that there is, but you never know maybe out there somewhere there is someone that allows this.
It seems I am having issues with WHM/CPanel. I cannot connect to mysql via phpmyadmin through WHM as a root and get this error
#2002 - The server is not responding (or the local MySQL server's socket is not correctly configured)
All users get the same error when they try to access mysql from cpanel. The access seems to be only for valid for 192.168.1.%
Would allowing access to localhost will help and how can I do that for all users?
I updated my php to 4.4.8 via easyapache. But after that my scripts couldn't connect the databases?
View 3 Replies View RelatedIf you have a socket F m/b, does a socket 940 heatsink works nicely on a socket F m/b? I can fit the original socket 940 heatsink on a socket F m/b but I am not sure whether there are any cooling related problems?
According to the thermal design guide, it says:
Quote:
The heat sink, fan, mounting spring clip, and thermal interface material used for the AMD PIB thermal solution for socket F (1207) processors are the same as the heat sink, fan, mounting spring clip, and thermal interface material used for systems based on the socket 940 processor.
The plastic retention frame, made of 20% glass-filled Lexan, is a two-piece implementation rather than the single-piece frame used for socket 940. This change accommodates the larger foot-print of socket F (1207) processors.
[url]
So are they interchangeable?
I do have socket F heatsinks just to save the hassle of testing and breaking things.
The reason I am asking is that it is tough to find socket F heatsinks here, and there are some socket 940 HSF floating around so I might as well use socket 940 HSF when somehow the ones that I have are not working or I run out of socket F coolers.
I have a set up where server 1 holds a mysql DB and a virtual host. server 2 holds many virtual hosts in apache (16) connecting to this DB.
The virtual hosts all hold the same script, but the single VH on server 1 receives about the same amount of visits as all the VHs of server 2.
server 1 is very busy at times, like 100% CPU and a load around 10 for long period of times.
server 2 is not very busy, around 30% CPU usage and 0.6 CPU load.
Yet, users on server 2 experience *much slower* response times than the ones on server 1.
The obvious reason could be the network between the two, but I'm not convinced (6 seconds for a query run from server 2 when it brings back 1 row and takes 0.01 second from server 1).
I was wondering what other reasons it could be.
The mysql processlist is weird:

Why so many sleeping processes from server 2, and none or almost none from server 1 ?
Is it normal that every query from server 2 is open on a different port ? Should they be grouped by virtual host, or is there one different port for each script running concurrently?
What could be a reason for server 2 having problems to open connections on server 1, and how to solve it?
Right now I'm about to deport more users from server 1 to new virtual hosts on server 2, hoping it will lower the load on the first machine and overall accelerate the response times. I just thought I'd post here first because this all seems very weird to me and i thought someone with an external look might tell me what I'm doing wrong. And also if network would be the problem maybe that's not the clever thing to do to make more users remote.
I have a problem with connection to MySQL database over PHP.

With one from another server. Now roundcube does not want to connect to mysql anymore, i tried to edit this :
line:$rcmail_config['db_dsnw'] = 'mysql://roundcube:randompassword@localhost/roundcubemail';
i then used a MD5 generator to input the hash in the password field of the roundcube user in mysql, with no luck...I even tried to delete roundcube user from mysql, then remove psa-roundcube, then go through the plesk update manager and install roundcube again, did not change nothing, it didn't even create the roundcube user.
Is there anyway i can reinstall roundcube from scratch?PPP 11.5 up to date on ubuntu 12.04
