Installation

• Start with minimal installation of CentOS7 (7.7 1908 is good).

• add CentOS-7-x86_64-Everything-1908.iso image as a local repo.

  • Remove all repose from /etc/yum.repos.d except CentOS-Media.repo

  • Mount the CentOS-7-x86_64-Everything-1908.iso at the location specified in CentOS-Media.repo:

    mount /dev/sr1 /etc/yum.repos.d/<location specified in CentOS-Media.repo>
    

  • Run yum repolist all to confirm successful installation of the repo.

• install: yum-utils vim

• activate ethernet port via nmtui

• configure proxy for yum:

  vim /etc/yum.conf
  proxy=http://<YOUR PROXY HERE>:8080
  

• disable chkconfig firewalld off and selinux (/etc/selinux/conf)

• add these mirrors (remove the local repo once done with this step): install_centos7_repos.sh

• (Optional) to install minimal Desktop:

  • yum install git redhat-lsb-core
  • Download the linux_wiki repo and run install_minimal_desktop.sh. See This link for more help.
