1.編輯/etc/sysconfig/network
[root@localhost ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=hadoop001
2.hostname直接命名
[root@localhost ~]#hostname hadoop001
3.編輯/etc/hosts
[root@localhost ~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.137.141 hadoop001
1~3步是針對CentOS6系統(tǒng)的操作尺迂，如果是CentOS7系統(tǒng)還需要
4.修改/etc/hostname
[root@localhost ~]# vi /etc/hostname
hadoop001
