MySQL修改时区的方法小结_MySQL
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
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
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
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'")
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。
