CentOS 修改主机全名

1、修改network

# vim /etc/sysconfig/network

NETWORKING=yes
HOSTNAME=jxpaiwp02     

把HOSTNAME=后面修改成为你想要的名字

HOSTNAME=jxpaiwp01

2、修改hosts

# vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6     

添加成这样

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
127.0.0.1       jxpaiwp01
192.168.8.11    jxpaiwp01
192.168.8.11    localhost
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

红色字体的为你的ip地址，
