I saw on SF that there's an option in MySQL to log all queries. So, in my version (mysql-server-5.0.45-7.el5 on CentOS 5.2) this appears to be a case of enabling the 'log' option, so I edited /etc/my.cnf to add this:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
old_passwords=
log=/var/log/mysql-general.log

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid

I then created the file and set permissions:

# touch /var/log/mysql-general.log
# chown mysql. /var/log/mysql-general.log
# ls -l /var/log/mysql-general.log
-rw-r--r-- 1 mysql mysql 0 Jan 18 15:22 /var/log/mysql-general.log

But when I start mysqld I get:

120118 15:24:18  mysqld started
^G/usr/libexec/mysqld: File '/var/log/mysql-general.log' not found (Errcode: 13)
120118 15:24:18 [ERROR] Could not use /var/log/mysql-general.log for logging (error 13). Turning logging off for the whole duration of the MySQL server process. To turn it on again: fix the cause, shutdown the MySQL server and restart it.
120118 15:24:18  InnoDB: Started; log sequence number 0 182917764
120118 15:24:18 [Note] /usr/libexec/mysqld: ready for connections.

Can anyone suggest why this isn't working?
