Question

I’m trying to setup mysql query profiling as highlighted in http://dev.mysql.com/doc/refman/5.1/en/log-destinations.html

In

/etc/my.cnf

I added:

general_log=1
log_output=FILE
log=/tmp/mysql.log

i did

/etc/init.d/mysqld restart
Stopping MySQL:                                            [  OK  ]
Starting MySQL:                                            [  OK  ]

My mysql version is:

Server version: 5.0.77 Source distribution

But it did not work! No /tmp/mysql.log

Answer 1

The problem you have is that log_output was introduced in 5.1.

Take a look: http://dev.mysql.com/doc/refman/5.1/en/server-system-variables.html#sysvar_log_output

Version Introduced 5.1.6

Also, in the article you pointed it says:

SET GLOBAL log_output=’TABLE’; SET GLOBAL general_log=’ON’;

which has the same effect (note that this is only possible in 5.1)
