Proxy settings for DNF in CentOS

We can set up proxy settings for the DNF package manager in CentOS and other Red Hat-based Linux distributions to enable it to access and download packages from the internet via a proxy server. This can be helpful in situations when access to the internet requires a proxy, such as in corporate settings. Here’s how to set up CentOS’s dnf proxy settings:

1. The DNF configuration file will be in /etc/dnf/dnf.conf. Open a terminal and change it with a text editor. To edit this file, we will require administrative privileges; if we are not the superuser, use the sudo command to obtain them.

2. To customize the proxy, add or change the following lines to the dnf.conf file:

i. In order to set up a proxy server in the format: http://<proxy_host>:<proxy_port>

ii. To indicate that a username and a password are needed to access the proxy:

In addition, if the proxy server needs authentication, enter the username and password.

3. Close the text editor after saving the changes.

4. Using simple dnf commands, such as updating the package cache, can be used to check if the proxy settings are functioning.

5. To access the package repositories, dnf will use the proxy if the proxy settings are established appropriately.

Conclusion

We can now use dnf as usual as the proxy settings are established. When requesting access to external repositories, the package management will automatically go through the designated proxy server.
