Proxy for ispmanager repositories in CentOS 7

Why?

The use of a proxy server is an effective solution for cases where a CentOS 7 server lacks access to ispmanager repositories.

Instructions

In order for the server to work with repositories through a proxy server, the following directives must be added to the repository files:

• proxy <proxy-server-address>;
• proxy_username <login> (optional);
• proxy_password <password> (optional).

Typically, modifications should be made to the repository files located in /etc/yum.repos.d:

• ispsystem.repo;
• ispsystem-base.repo;
• exosoft.repo;
• epel.repo.

As repository files can contain multiple sections, denoted by the name in square brackets (e.g. [epel]), it is important that directives should be added to those sections where the following directives are present:

• mirrorlist with a value that looks like "https://download.ispmanager.com/...";
• enable with a value set to "1".
