MySQL won't start in CentOS 5.5 and the “ERROR 2002”

Question

I would like to ask a help for the problem I encountered. My mysql server suddenly stopped after I install php-soap. I don't know why it get stopped actually...

Since it's stopped I tried to start it by typing the line:

# /etc/init.d/mysqld start

After this, I get this message:

MySQL Daemon failed to start.
Starting mysqld:                                           [FAILED]

Starting mysql seems failed. Since I tried it numerous times and got this result a numerous time. I checked the mysqlog and here's what I got.

==== MYSQL LOG ====

120511 21:34:43 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

Other infos:

OS: CentOS 5.5 64bit

Mysql Version: Sorry I couldn't get the version of mysql installed on my server due this error I am getting:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

Can somebody help me to resolve this problem?

Thank you in advanced.

Answer 1

looks like your installation of mysql is not corrupt with /usr/share/mysql/english/errmsg.sys having been modified to contain less than the number of entries needed.

i would get the installation/src files for mysql for your centos box again. Untar it and locate the file errmsg.sys from sql/share/english, copy it to /usr/share/mysql/english/errmsg.sys and restart your mysqld. Another option is just to reinstall mysql from centos repo, after backing up your dbs to make sure they don't get blown away and to have a copy/backup of it.

I would also find out what made the changes to the errmsg.sys file.
