Mysql logging on CentOS 5.3

for whatever reason when i edited my.cnf on CentSO 5.3 the logging options were never picked up no matter what i tried

gave up messing with my.cnf and put them directly in the init.d file and all was well

1

make sure that the log files are available and writeable by the mysql user

2

edit /etc/init.d/mysqld

find the mysqld_safe section and add the --log** sections in as below

# but we need to be sure.
/usr/bin/mysqld_safe   --datadir="$datadir" --socket="$socketfile"
    --log-error="$errlogfile" --pid-file="$mypidfile"
    --log=/var/log/mysql.log 
    --log-slow-queries
    --slow_query_log_file=/var/log/mysql-slow.log 
    --federated 
    --user=mysql >/dev/null 2>&1 &

3

sudo /etc/init.d/mysql restart

and your off logging as normal

note: the general log ( –log=/var/log/mysql.log ) will slow this down
