Installing GitLab with Omnibus packages

Prerequisites

• Installation Requirements.
• If you want to access your GitLab instance via a domain name, like mygitlabinstance.com, make sure the domain correctly points to the IP of the server where GitLab is being installed. You can check this using the command host mygitlabinstance.com.
• If you want to use HTTPS on your GitLab instance, make sure you have the SSL certificates for the domain ready. (Note that certain components like Container Registry which can have their own subdomains requires certificates for those subdomains also.)
• If you want to send notification emails, install and configure a mail server (MTA) like sendmail. Alternatively, you can use other third party SMTP servers.
