How to get ISPsystem repositories to work through a proxy

You can set up a proxy to resolve the issue when ISPsystem repositories are not accessible. Complete the following steps to add the proxy for repositories on CentOS 7:

1. Go to the directory with a list of the connected repositories:

   cd /etc/yum.repos.d

2. For every repository you will see the .repo file with the following contents:

   ###[ispsystem-__VERSION__]
   ###name=ispsystem-__VERSION__
   ####baseurl=https://download.ispsystem.com/repo/centos/__VERSION__/$releasever/$basearch
   ###mirrorlist=https://download.ispsystem.com/repo/centos/__VERSION__/mirrorlist.txt
   [ispsystem-5.173]
   name=ispsystem-5.173
   failovermethod=priority
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-ISPsystem
   enabled=1
   #baseurl=https://download.ispsystem.com/repo/centos/5.173/$releasever/$basearch
   mirrorlist=https://download.ispsystem.com/repo/centos/5.173/mirrorlist.txt
   gpgcheck=1

   Please note that the file may contain several sections, e.g.:

   [epel]
   name=Extra Packages for Enterprise Linux 7 - $basearch
   #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch
   mirrorlist=https://download.ispsystem.com/repo/centos/epel/mirrorlist.txt
   failovermethod=priority
   enabled=1
   gpgcheck=1
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
   
   [epel-debuginfo]
   name=Extra Packages for Enterprise Linux 7 - $basearch - Debug
   #baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch/debug
   mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-debug-7&arch=$basearch
   failovermethod=priority
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
   gpgcheck=1
   
   [epel-source]
   name=Extra Packages for Enterprise Linux 7 - $basearch - Source
   #baseurl=http://download.fedoraproject.org/pub/epel/7/SRPMS
   mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-source-7&arch=$basearch
   failovermethod=priority
   enabled=0
   gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
   gpgcheck=1

3. Add a proxy if the .repo file contains the mirrorlist parameter which value starts with the domain "https://download.ispsystem.com". Usually, these are the repositories ispsystem.repo, ispsystem-base.repo and epel.repo. Add a proxy for the repository using this parameter:

   proxy=<proxy address>

   View details

   <proxy address> — in the format http://IP address:port/

4. Add the authentication parameters:

   proxy_username=<login>
   proxy_password=<password>

   View details

   <login> — the proxy username 

   <password> — the proxy user password 

5. If the file contains only one section, add the parameter to the end of the file. E.g. the files ispsystem.repo and ispsystem-base.repo contain only one section. If there are several sections, add parameters into a required section. The section can be defined with the enabled parameter, the parameter value – "1".
