centos 修改时区_mysql 修改时区_centos7 修改时区

Time zone: Asia/Shanghai (CST, +0800)

NTPenabled: yes

NTP synchronized: yes

RTC in local TZ: no

DSTactive: n/a

[root@node3 ~]#

1、cp /usr/share/zoneinfo/asia/shanghai /etc/localtime。ln -s /usr/share/zoneinfo/asia/shanghai /etc/localtime。ln -s /usr/share/zoneinfo/asia/shanghai /etc/localtime 。

链接到上海时区文件

ln -sf /usr/share/zoneinfo/Asia/Shanghai/etc/localtime

执行完上述过程后centos 修改时区，重启机器，即可看到时区已经更改。

其实是马上生效了。

此时查看timedatectl也可以看到时区改了。

方法三，不好用，重启或者系统有异常时会还原成原来的时区。（难道是我的系统问题？）

in csh, this command sets the environment variable path, such that the shell will search for files in the /bin, /usr/bin, /usr/sbin and /usr/local/bin directories, in that order.。shell scripts where the underling shell accepts a ''-c'' argument can use the linux/sh386 format. upx decompresses the shell scriptinto low memory, then maps the shell and passes the entire text of the script as an argument with a leading ''-c''. it does not use space in /tmp, and does notuse /proc.。the/usr/java symbolic link can change the default java platform because there are symbolic links in/usr/bin (also known as/bin) that use it. (for example, the/usr/bin/java link refers to/usr/java/bin/java, which is the java 2 runtime environment). many java applications are compatible with later versions of the java platform, but some applications might be less compatible.。
