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    |
| 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)
