Linux server hosts file configuration

Hosts file is a file responsible for rapid resolution of IP address and domain name in Linux system. It is saved in "/ etc" directory in ASCII format, and the file name is "hosts".

The hosts file contains the mapping between IP addresses and hostnames, as well as aliases for hostnames. In the absence of a domain name server, all network programs on the system resolve the IP address corresponding to a host name by querying the file, otherwise they need to use DNS service programs to solve the problem. Usually, the commonly used domain name and IP address mapping can be added to the hosts file to achieve fast and convenient access.

Let's introduce the methods and steps to modify the hosts configuration file:

Required tools: vim/vi

Sudo apt install vim-y # debiansudo yum install vim-y # readhat

2. Modify the hosts file using the editor
