How to change mysql.sock? - mysql

Question

I have installed mysql through binary installation and followed below steps
http://dev.mysql.com/doc/refman/5.0/en/binary-installation.html
Right now sock files are craeted on /tmp/mysql.sock when mysql service is started.
I want to know which configuration files need to be edited to change the path of mysql.sock
I tried the following steps to change mysql.sock path from /tmp/mysql.sock to /var/lib/mysql/mysql.sock
1.I tried to enter socketpath in /etc/my.cnf
socket =/var/lib/mysql/mysql.sock
2./etc/init.d/mysql
basedir=/var/lib/mysql
datadir=/var/lib/mysql/data
socket=/var/lib/mysql/mysql.sock
Can anybody help me to fix this issue.

Answer 1

Setting these variables in my.cnf should work just fine (Tested locally, Ubuntu 10.10).
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
Just make sure you're restarting MySQL Service?
Below is what I did, this is on Fedora (Since you're using RHEL this should more mimic your setup):
[root#rudi /]# ls /var/lib/mysql/
ibdata1 ib_logfile0 ib_logfile1 mysql mysql.sock
[root#rudi /]# ls /var/run/mysqld/
mysqld.pid
[root#rudi /]# nano /etc/my.cnf
[root#rudi /]# service mysqld restart
Stopping mysqld: [ OK ]
Starting mysqld: [ OK ]
[root#rudi /]# ls /var/lib/mysql/
ibdata1 ib_logfile0 ib_logfile1 mysql
[root#rudi /]# ls /var/run/mysqld/
mysqld.pid mysql.sock
The only thing that I changed was socket= this time, and restarting still worked fine.
Are you sure that you're not editing socket within the [client] section of my.cnf? It must be under the [mysqld] section.
