Detailed introduction to linux host name configuration

1. Configure Linux hostname

Configure the client host
Configure the server host

2. Configure hostname and IP mapping

3. Testing

4. Configure windows hosts

5. Windows test

1. Configure Linux hostname

Next, configure two centos7 virtual machines, with the host names configured as client and server, and their host IP addresses as 192.168.30.8 and 192.168.30.9 respectively.

Configure the client host

[root@client ~]# vi /etc/sysconfig/network

Add the following content and save:

# Created by anaconda
NETWORKING=yes
hostname=client

 Restart the network:

[root@client ~]# systemctl restart network
[root@client ~]# hostname
client
[root@client ~]#

If it does not work, you can use the following command:

[root@client ~]# hostnamectl set-hostname client

Configure the server host

[root@server ~]# hostnamectl set-hostname server

Restart the network:

[root@server ~]# systemctl restart network
[root@server ~]# hostname
server
[root@server ~]# uname -n
server

2. Configure hostname and IP mapping

Configure the hosts files of client and server

vi /etc/hosts

Add the following content:

192.168.30.8 client
192.168.30.9 server

3. Testing

Test whether the configuration is successful by pinging hostname:

client pings server:

[root@client ~]# ping server -c 3
PING server (192.168.30.9) 56(84) bytes of data.
64 bytes from server (192.168.30.9): icmp_seq=1 ttl=64 time=0.616 ms
64 bytes from server (192.168.30.9): icmp_seq=2 ttl=64 time=0.384 ms
64 bytes from server (192.168.30.9): icmp_seq=3 ttl=64 time=0.566 ms

--- server ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2001ms
rtt min/avg/max/mdev = 0.384/0.522/0.616/0.099 ms
[root@client ~]#

server pings client:

[root@Server ~]# ping client -c 3
PING client (192.168.30.8) 56(84) bytes of data.
64 bytes from client (192.168.30.8): icmp_seq=1 ttl=64 time=0.502 ms
64 bytes from client (192.168.30.8): icmp_seq=2 ttl=64 time=0.678 ms
64 bytes from client (192.168.30.8): icmp_seq=3 ttl=64 time=0.323 ms

--- client ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 0.323/0.501/0.678/0.144 ms
[root@Server ~]#

After configuring the hostname and IP mapping, you can directly ping the host name instead of pinging the IP address.

4. Configure windows hosts

Configure Windows hosts so that you can access it by host name under Windows.

Edit the C:\Windows\System32\drivers\etc\hosts file and add the following content:

192.168.30.8 client
192.168.30.9 server

save

5. Windows test

C:\Users\10287>ping client -n 3

Pinging client [192.168.30.8] with 32 bytes of data:
Reply from 192.168.30.8: Bytes=32 Time<1ms TTL=64
Reply from 192.168.30.8: Bytes=32 Time<1ms TTL=64
Reply from 192.168.30.8: Bytes=32 Time<1ms TTL=64

Ping statistics for 192.168.30.8:
    Packets: Sent = 3, Received = 3, Lost = 0 (0% loss),
Estimated round trip time in milliseconds:
    Shortest = 0ms, Longest = 0ms, Average = 0ms
