修改MySQL的时区，涉及参数time_zone

首先需要查看mysql的当前时区,用time_zone参数

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

1 可以通过修改my.cnf

在 [mysqld] 之下加

default-time-zone=timezone

来修改时区。如：

default-time-zone = '+8:00'

修改完了记得记得重启msyql

注意一定要在 [mysqld] 之下加 ，否则会出现 unknown variable 'default-time-zone=+8:00'

2 另外也可以通过命令行在线修改

[html]set time_zone = timezone  比如北京时间（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 再通过select now()来验证时区

[html]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)  [html]mysql> show variables like '%time_zone%';  +------------------+--------+  | Variable_name    | Value  |  +------------------+--------+  | system_time_zone | CST    |  | time_zone        | +00:00 |  +------------------+--------+  2 rows in set (0.00 sec)  [html]mysql> select now();  +---------------------+  | now()               |  +---------------------+  | 2013-08-05 02:35:43 |  +---------------------+  1 row in set (0.00 sec)
