This article mainly explains "how to modify the host name of Linux". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to modify the host name by Linux".

View the hostname command [root@tonyx ~] # uname-ntonyx [root@tonyx ~] # hostnametonyx through the hostname command

Command format: hostname newhostname temporarily modifies the host name. Log out and log in again with the logout command. But not permanently.

Modify via configuration file / etc/sysconfig/network

Modify this configuration file, and the linux hostname will take effect after the next restart. If you want to take effect immediately and permanently, you need to cooperate with the hostname command.

[root@tonyx ~] # cat / etc/sysconfig/networkNETWORKING=yesHOSTNAME=tonyxu file / etc/hosts function

One line of this file corresponds to a comparison, and the format of each line is: the alias of the ip global hostname hostname mainly provides a comparison between the ip and the hostname. To establish an associated "database" between the domain names of some commonly used web addresses and their corresponding IP addresses. When a user enters a URL that needs to be logged in in the browser, the system will first automatically find the corresponding IP address from the Hosts file. Once found, the system will immediately open the corresponding web page, which is equivalent to DNS parsing. For example, if the ip of baidu is 220.181.57.217, you can add a line at the end of the file:

[root@tonyx ~] # cat / etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6220.181.57.217 baidu.com here, I believe you have a better understanding of "how to modify the host name in Linux".
