设置主机名

如果您想更改系统的主机名，请按如下方式设置。

[1] 更改主机名。（但是当系统重新启动时，它会回来） 
# show current hostname
[root@localhost ~]# hostname
localhost.localdomain
# change hostname
[root@localhost ~]# hostname dlp.srv.world
[root@localhost ~]# hostname
dlp.srv.world     # changed
[2] 永久更改主机名。 
[root@localhost ~]# hostnamectl set-hostname dlp.srv.world
