How to Install GitLab CE in a disconnected environment

• Download the package from: https://packages.gitlab.com/gitlab/gitlab-ce
  • click on the RPM link for the OS and download the RPM file.

$ wget --content-disposition https://packages.gitlab.com/gitlab/gitlab-ce/packages/el/8/gitlab-ce-14.5.2-ce.0.el8.x86_64.rpm/download.rpm

• And transfer to server.

• Follow https://about.gitlab.com/install for the instructions
• enable repos needed
• install dependencies

$ sudo dnf install -y \
    curl \
    policycoreutils \
    openssh-server \
    perl \
    postfix \
    openssl \
    tzdata \
    yum-utils
# Enable OpenSSH server daemon if not enabled: sudo systemctl status sshd
sudo systemctl enable sshd 
sudo systemctl start sshd

# Check if opening the firewall is needed with: sudo systemctl status firewalld
$ sudo firewall-cmd --permanent --add-service=http && \
    sudo firewall-cmd --permanent --add-service=https && \
    sudo systemctl reload firewalld

Postfix

$ sudo dnf install postfix && \
    sudo systemctl enable postfix && \
    sudo systemctl start postfix

Install Git

• make sure RHEL repos are enabled (local or satellite)

$ sudo EXTERNAL_URL="http://gitlab.lab.local" \
    GITLAB_ROOT_PASSWORD="gitlabadmin" \
    dnf localinstall -y gitlab-ce-14.5.2-ce.0.el8.x86_64.rpm

Note:

1. If any error with gpgchec, then disable gpgcheck by adding --nogpgcheck at the end of dnf or yum command.
2. If you missed to mention the root password while installing, then get the default randomg password generated by installaer. (This password will be removed by gitlab-ctl reconfigure later.)

$ sudo cat /etc/gitlab/initial_root_password
