更改 /etc/sysconfig/network 文件下 HOSTNAME 属性。

[root@iZ2zeiba2yyjy571kc00ghZ ~]# vim /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=wch #更改为自己的主机名
NETWORKING_IPV6=no
PEERNTP=no
GATEWAY=172.17.191.253

more 命令查看文件内容

[root@iZ2zeiba2yyjy571kc00ghZ ~]# more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=wch
NETWORKING_IPV6=no
PEERNTP=no
GATEWAY=172.17.191.253

更改 /etc/hosts 文件，格式为：

ip hostname localhost

[root@iZ2zeiba2yyjy571kc00ghZ ~]# vim /etc/hosts
127.0.0.1 wch  localhost
[root@iZ2zeiba2yyjy571kc00ghZ ~]#  ping wch
