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

 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

 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

 mysql> show variables like '%time_zone%';
 +------------------+--------+
 | Variable_name    | Value  |
 +------------------+--------+
 | system_time_zone | CST    |
 | <span style="color:#3366ff;">time_zone        | +08:00 span>|
 +------------------+--------+
 2 rows in set (0.00 sec)

 mysql> select now();
 +---------------------+
 | now()               |
 +---------------------+
 | <span style="color:#3333ff;">2013-08-05 10:35:31 span>|
 +---------------------+
 1 row in set (0.00 sec)

 mysql>  <span style="color:#ff0000;">set span><span style="color:#ff0000;">time_zone='+0:00';
 span>Query OK, 0 rows affected (0.00 sec)

 mysql> show variables like '%time_zone%';
 +------------------+--------+
 | Variable_name    | Value  |
 +------------------+--------+
 | system_time_zone | CST    |
 |<span style="color:#ff0000;"> time_zone        | +00:00 span>|
 +------------------+--------+
 2 rows in set (0.00 sec)

 mysql> select now();
 +---------------------+
 | now()               |
 +---------------------+
 | <span style="color:#ff0000;">2013-08-05 02:35:43 span>|
 +---------------------+
 1 row in set (0.00 sec)
