修改MySQL的時區，涉及參數time_zone

 

首先需要查看mysql的當前時區,用time_zone參數

mysql> show variables like '%time_zone%';   +------------------+--------+| Variable_name    | Value  |+------------------+--------+| system_time_zone | CST    || time_zone        | SYSTEM |+------------------+--------+2 rows in set (0.00 sec)

1 可以通過修改my.cnf
在 [mysqld] 之下加
default-time-zone=timezone
來修改時區。如：
default-time-zone = '+8:00'
修改完了記得記得重啟msyql
注意一定要在 [mysqld] 之下加 ，否則會出現 unknown variable 'default-time-zone=+8:00'

2 另外也可以通過命令列線上修改

set time_zone = timezone比如北京時間（GMT+0800）set time_zone = '+8:00'; 如下:mysql> set time_zone='+8:00';Query OK, 0 rows affected (0.00 sec)mysql> show variables like '%time_zone%';   +------------------+--------+| Variable_name    | Value  |+------------------+--------+| system_time_zone | CST    || time_zone        | +08:00 |+------------------+--------+2 rows in set (0.00 sec)

 

3 再通過select now()來驗證時區

mysql> show variables like '%time_zone%';   +------------------+--------+| Variable_name    | Value  |+------------------+--------+| system_time_zone | CST    || time_zone        | +08:00 |+------------------+--------+2 rows in set (0.00 sec)mysql> select now();+---------------------+| now()               |+---------------------+| 2013-08-05 10:35:31 |+---------------------+1 row in set (0.00 sec)mysql>  set time_zone='+0:00';Query OK, 0 rows affected (0.00 sec)

mysql> show variables like '%time_zone%';+------------------+--------+| Variable_name    | Value  |+------------------+--------+| system_time_zone | CST    || time_zone        | +00:00 |+------------------+--------+2 rows in set (0.00 sec)

mysql> select now();+---------------------+| now()               |+---------------------+| 2013-08-05 02:35:43 |+---------------------+1 row in set (0.00 sec)
