If you’ve ever needed to change the hostname for Red Hat Linux, CentOS or similar operating systems, you can do so easily with one simple command.

如果您曾经需要更改Red Hat Linux，CentOS或类似操作系统的主机名，则可以使用一个简单的命令轻松地进行更改。

Just use the echo command to replace the contents of /proc/sys/kernel/hostname with your new host name.

只需使用echo命令将/ proc / sys / kernel / hostname的内容替换为新的主机名。

# echo hostname.com > /proc/sys/kernel/hostname

# echo hostname.com > /proc/sys/kernel/hostname

Then restart the network interfaces:

然后重新启动网络接口：

# /etc/init.d/network restart Shutting down interface venet0:  [  OK  ] Shutting down loopback interface:  [  OK  ] Bringing up loopback interface:  [  OK  ] Bringing up interface venet0: RTNETLINK answers: File exists RTNETLINK answers: File exists [  OK  ]

Now you can use the hostname command to verify that it has changed.

现在，您可以使用hostname命令来验证它是否已更改。
