CentOS下调整系统时区

首先查看当前系统时区：

*[root@localhost lampp]# cat /etc/sysconfig/clock 
# The time zone of the system is defined by the contents of /etc/localtime.
# This file is only for evaluation by system-config-date, do not rely on its
# contents elsewhere.
ZONE="Asia/Chongqing"*

系统显示当前时区是亚洲重庆时区，如果我们想调整时区为上海

[root@localhost lampp]# cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime 
cp: overwrite `/etc/localtime'? 

然后输入y,或者用

 cp /usr/share/zoneinfo/Asia/Shanghai  /etc/localtime  -f

重启系统就好了
