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