Linux下修改时区:
[root@bogonetc]# date
Thu Nov 2 01:59:16 Asia 2017 //时间不对,差在时区上
使用如下命令,导入配置文件
[root@bogon ~]#export TZ='Asia/Shanghai' //TZ名字自己定,新增一个环境变量
[root@bogon ~]#source ~/.bashrc //使环境变量生效
[root@bogon ~]#sudo rm -f /etc/localtime //去使能当前的时区设置
[root@bogon ~]#sudo ln -s /usr/share/zoneinfo/Asia/ShangHai /etc/localtime 使新的配置生效
最后查看时区
[root@bogon ~]#date
Thu Nov 2 10:03:36 CST 2017
为了使重启后生效,需要修改/etc/sysconfig/cloc文件内容
ZONE="Asia/Shanghai"
最后执行命令生效
[root@bogonsysconfig]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
重启后,时间正确。
查找时区名称的命令tzselect
