导读：方法一：更改my.cnf配置文件

vi /usr/local/kkmail/config/mysql/my.cnf

将下面两行注释取消掉，然后重启mysql

#general_log = 1

#general_log_file = /tmp/kkmail_mysql.log

# 设置general log

方法一：更改my.cnf配置文件

vi /usr/local/kkmail/config/mysql/my.cnf

将下面两行注释取消掉，然后重启mysql

#general_log = 1

#general_log_file = /tmp/kkmail_mysql.log

# 设置general log保存路径

# 好像只能设置保存到 /tmp 或 /var 文件夹下。

方法二：在mysql命令控制台操作

# 需要root用户才有访问此文件的权限

mysql> show global variables like '%general%';
