1：安裝linux

2：修改機器名

hostname 顯示主機名

[jifeng@localhost bin]$ hostname localhost.sohudo 編輯主機名配置文件 [jifeng@localhost bin]$ vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=localhost.sohudo 用root登錄 [jifeng@localhost bin]$ su - 密碼： [root@localhost ~]# vi /etc/sysconfig/network NETWORKING=yes HOSTNAME=localhost.sohudo ~

把HOSTNAME修改為jifeng01

[jifeng@jifeng01 ~]$ hostname jifeng01

3: 配置hosts文件

[jifeng@jifeng01 ~]$ su - 密碼： [root@jifeng01 ~]# vi /etc/hosts127.0.0.1 localhost localhost.sohudo ::1 localhost localhost.sohudo后面加2行

10.3.7.212 ?jifeng01
10.3.7.214 ?jifeng02

"/etc/hosts" 4L, 120C written [root@jifeng01 ~]# [root@jifeng01 ~]# ping jifeng02 PING jifeng02 (10.3.7.214) 56(84) bytes of data. 64 bytes from jifeng02 (10.3.7.214): icmp_seq=1 ttl=64 time=0.577 ms 64 bytes from jifeng02 (10.3.7.214): icmp_seq=2 ttl=64 time=0.219 ms 64 bytes from jifeng02 (10.3.7.214): icmp_seq=3 ttl=64 time=0.419 ms ^C --- jifeng02 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2740ms rtt min/avg/max/mdev = 0.219/0.405/0.577/0.146 ms測試OK
