    Please select one of the following time zone regions.
    1) Beijing Time
    2) Xinjiang Time
    #? 1
    
    The following information has been given:
    
            China
            Beijing Time
    
    Therefore TZ='Asia/Shanghai' will be used.
    Local time is now:      Mon Aug 19 17:02:35 CST 2019.
    Universal Time is now:  Mon Aug 19 09:02:35 UTC 2019.
    Is the above information OK?
    1) Yes
    2) No
    #? 1
    
    You can make this change permanent for yourself by appending the line
            TZ='Asia/Shanghai'; export TZ
    to the file '.profile' in your home directory; then log out and log in again.
    
    Here is that TZ value again, this time on standard output so that you
    can use the /usr/bin/tzselect command in shell scripts:
    Asia/Shanghai
    

    删除 localtime

    [root@localhost ~]# rm /etc/localtime
    

    建立连接

    [root@localhost ~]# ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
    

    使用 date 命令查看已设置成功

    [root@localhost etc]# date
    Mon Aug 19 17:19:00 CST 2019
