For frequently visited websites, we can configure the mapping relationship between domain names and IPs in Hosts, so how to configure HOSTS files in Linux systems?

HOSTS file introduction: The main role of HOSTS file is to establish an association "database" between some commonly used URL domain names and corresponding IP addresses.

When the user enters a URL to log 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, if not found, the system will submit the URL to the DNS domain name resolution server for IP address resolution.

HOSTS files can speed up domain name resolution. Because of the mapping, when we enter a domain name, the computer can quickly resolve the IP without having to request a DNS server on the network.

To modify the hosts file, you need to modify the file/etc/hosts and restart tomcat to modify the file/etc/hostsStep 1: Enter the command vi /etc/hosts to open the editing text mode of hostsStep 2: Enter the command i to enter the editing mode. At this time, you may prompt: changing a "readonly" file attentionAt this time, you can use the command to force the file permissions to change: sudo vi /etc/hosts Enter the corresponding password, enter, enter the editing mode to modify the content Complete Step 3: Enter the command:wq Save and exit Step 4: Enter command: cat /etc/hosts Check whether the modified hosts file content is modified successfully
