修改MySQL資料庫的時區,涉及參數time_zone

修改MySQL的時區,涉及參數time_zone

 

首先需要查看mysql的當前時區,用time_zone參數

 

[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 可以通過修改my.cnf

在 [mysqld] 之下加

default-time-zone=timezone

來修改時區。如:

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

修改完瞭記得記得重啟msyql

註意一定要在 [mysqld] 之下加 ,否則會出現 unknown variable 'default-time-zone=+8:00'

 

2 另外也可以通過命令行在線修改

 

[html]
set time_zone = timezone  
比如北京時間(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 再通過select now()來驗證時區

[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)
