本文实例总结了MySQL修改时区的方法。分享给大家供大家参考,具体如下:

说明:这里总结记录修改mysql时区的三种方法。

方法一:通过mysql命令行模式下动态修改

1.1 查看mysql当前时间,当前时区

> select curtime();  #或select now()也可以
+-----------+
| curtime() |
+-----------+
| 15:18:10 |
+-----------+
> show variables like "%time_zone%";
+------------------+--------+
| Variable_name  | Value |
+------------------+--------+
| system_time_zone | CST  |
| time_zone    | SYSTEM |
+------------------+--------+
2 rows in set (0.00 sec)
#time_zone说明mysql使用system的时区,system_time_zone说明system使用CST时区

Copy after login

1.2 修改时区

> set global time_zone = '+8:00'; ##修改mysql全局时区为北京时间,即我们所在的东8区
> set time_zone = '+8:00'; ##修改当前会话时区
> flush privileges; #立即生效

Copy after login

方法二:通过修改my.cnf配置文件来修改时区

# vim /etc/my.cnf ##在[mysqld]区域中加上
default-time_zone = '+8:00'
# /etc/init.d/mysqld restart ##重启mysql使新时区生效

Copy after login

方法三:如果不方便重启mysql,又想临时解决时区问题,可以通过php或其他语言在初始化mysql时初始化mysql时区

这里,以php为例,在mysql_connect()下使用:

mysql_query("SET time_zone = '+8:00'")
Copy after login

这样可以在保证你不重启的情况下改变时区。但是mysql的某些系统函数还是不能用如:now()。这句,还是不能理解。
