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)
