In this article, we will show you how to enable proxy settings for yum command on CentOS 7. Yum is a package manager tool that works with RPM packages. It is available on RedHat Enterprise Linux, CentOS, and older versions of Fedora, and it is the most convenient way to handle OS packages and its dependencies on these operating systems.
When a server can only be accessed through proxy servers, you need to configure yum to use a proxy server so you can install a RPM package, or update the currently installed OS packages.
To configure a proxy server so the system user can access and use yum commands is fairly easy and straight to the point task, and it shouldn’t take more then 5 minutes to configure it. Let’s get started.
1. Configure proxy settings
Edit the ‘/etc/yum.conf’ yum configuration file and specify the proxy settings in the main section e.g.:
I need a socks 5 proxy server that can run on centos. This would use a block of IP's so that client X with IP Address zzz connects tomy proxy server with ip xxx and then to remote host with ip yyy. VPS Debian Wheezy already has installed Dante server. What I would like to achive is to be able to use theese 5 IP adreses with software callled Scrapebox and eXdomain to check expiry date for expiring domains which requires socks 5 proxy (NOT anonymous http proxy which I already have set up).

How to set up danted (dante-server) SOCKS proxy on Linux/Debian with authentication June 24, 2012 November 1, 2015 tiq The following post describes how to set up dante-server (danted / sockd), a SOCKS5 proxy server, with user/password authentication.
Where:
- proxy is the Proxy server URL (domain name or IP address) that yum should use including the TCP port number. In this example, proxysever.yourdomain.com is the URL of the proxy server. Do not forget to change 3128 with the actual port number of the proxy server.
- proxy_username is the proxy server username to use for the proxy URL. If this is unset it inherits it from the global setting.
- proxy_password is the proxy server password to use for the proxy URL. If this is unset it inherits it from the global setting.
Make sure to use a strong password for the proxy password. Use a password that is not the same with any other system user password, especially the root user password.
Please note that all users should have read access to /etc/yum.conf file so they can connect to the proxy server with those details when using yum commands.
2. Enable proxy access for a specific system user only
If for some reason you want to enable proxy access only for a specific system user, you need to add these lines to the user’s shell profile:
If the user is using the default bash shell, the user profile should be set in ~/.bash_profile file. The settings we used in this example should enable yum to use the proxy server proxysever.yourdomain.com, connecting to port 3128.

If the proxy server requires a username and password, edit the user’s shell profile and add the username and password to URL of the proxy server:
Do not forget to replace rhproxy, D5znQs4P8Rmtw, proxysever.yourdomain.com and 3128 with the actual proxy username, proxy user password, proxy URL and the port number of the proxy server respectively.
3. Test the settings
In order to check if proxy settings are configured properly, run some yum command, for example, try to use:
