開啟方法很簡單：編輯/etc/my.cnf檔案，在[mysqld]節下面新增：log=/var/lib/mysql/sql_row.log行（日誌的路徑自己根據需要定義）。

[mysqld] 
datadir=/var/lib/mysql 
socket=/var/lib/mysql/mysql.sock 
user=mysql 
# Default to using old password format for compatibility with mysql 3.x 
# clients (those using the mysqlclient10 compatibility package). 
old_passwords=1 
log=/var/lib/mysql/sql_row.log 
# Disabling symbolic-links is recommended to prevent assorted security risks; 
# to do so, uncomment this line: 
# symbolic-links=0 
[mysqld_safe] 
log-error=/var/log/mysqld.log 
pid-file=/var/run/mysqld/mysqld.pid
 

service mysql restart 
# 或者 
/etc/init.d/mysqld stop 
/etc/init.d/mysqld start
