MySQL日志文件相信大家都有很多的了解，MySQL日志文件一般在:ar/log/mysqld.log，下面就教您修改MySQL日志文件位置的方法，供您参考。

今天需要改MySQL日志文件的位置，发现在/etc/my.cnf中怎么也改不了。

后来发现MySQL日志位是指定的:

[root@localhost?etc]#?ps?aux|grep?mysqld

root?11830?0.5?0.0?4524?1204?pts/0?S?03:03?0:00?/bin?/usr/bin/mysqld_safe?--datadir=/data/mysql?--socket=arb/mysql/mysql.sock?--log-error=ar/log/mysqld.log?--pid-file=ar/run/mysqld/mysqld.pid

mysql?11890?3.7?0.1?40456?9076?pts/0?Sl?03:03?0:00?/usrbexec/mysqld?--basedir=/usr?--datadir=/data/mysql?--user=mysql?--pid-file=ar/run/mysqld/mysqld.pid?--skip-external-locking?--port=3306?--socket=arb/mysql/mysql.sock

root?11909?0.0?0.0?3908?664?pts/0?S+?03:03?0:00?grep?mysqld

chkconfig?--list发现是chkconfig?on指定的，天是

vim?/etc/init.d/mysqld得知这里的已经配置

get_mysql_option?mysqld?datadir?"arb/mysql"

datadir="$result"

get_mysql_option?mysqld?socket?"$datadir/mysql.sock"

socketfile="$result"

get_mysql_option?mysqld_safe?log-error?"ar/log/mysqld.log"

errlogfile="$result"

get_mysql_option?mysqld_safe?pid-file?"ar/run/mysqld/mysqld.pid"

mypidfile="$result"

更改这里应该就行了
