3. 設(shè)置時(shí)間

$ sudo timedatectl set-time 15:26:58$ timedatectl
Local time: Mon 2016-08-29 15:27:00 CST

PS:下面看下CentOS修改服務(wù)器系統(tǒng)時(shí)間

linux安裝完畢后，一般都是國(guó)外的世界，一點(diǎn)都不方便設(shè)置任務(wù)，或者導(dǎo)致網(wǎng)站獲取本地的時(shí)間錯(cuò)亂，所以就需要把服務(wù)器的時(shí)間改為和本地時(shí)間一致，也就是換成中國(guó)的時(shí)間。

第一條指令：date –s '2016-10-31 10:10:10'

第二條指令：clock –w //將日期寫(xiě)入CMOS

時(shí)間按照上面的格式，操作完畢可以再用

date

查看服務(wù)器時(shí)間，如果和設(shè)置的一樣，就表示成功了
