Fixing gitlab 12.0 after OS updates

Unfortunately I'm currently stuck with gitlab 12.0.x as I want to use mysql, my server is still 32bit and only has 8G of RAM for all services it's running. I do plan to move gitlab to a docker container on a x86_64 server but at this time I'm stuck with what I have.

Now most of the ruby packages for gitlab are installed for the gitlab user, however some are shared system and even then some of the local ones are linked against system libs if they've a native component.

On occasion gitlab won't work correctly and needs a recompile of components. The below runs as the git user after stopping gitlab. There's some slight changes to the official docs to ensure the ruby components are rebuilt and not reusing the potentially broken already installed ones.

I'm not sure if the backup would work prior to doing this but it's advisable to try before stopping the service.

Let's get to it.

Backup - as git user.

$ bundle exec rake gitlab:backup:create RAILS_ENV=production

Stop the service - probably best as root

$ service gitlab stop

Reinstall all the gitlab components - as git user.

$ cd /home/git/gitlab-shell/
$ bin/compile 

$ cd /home/git/gitlab-workhorse
$ make clean
$ make

$ cd /home/git/gitaly/
$ make clean
$ cd  /home/git/gitaly/ruby && bundle install --redownload --deployment
$ cd ..
$ make

$ cd /home/git/gitlab-pages/
$ make

$ cd /home/git/gitlab
$ bundle install --redownload --deployment --without development test postgres aws kerberos
$ bundle clean
$ bundle exec rake db:migrate RAILS_ENV=production
$ bundle exec rake gettext:compile RAILS_ENV=production
$ bundle exec rake yarn:install gitlab:assets:clean gitlab:assets:compile RAILS_ENV=production NODE_ENV=production NO_SOURCEMAPS=true
$ bundle exec rake cache:clear RAILS_ENV=production

Start the gitlab service back up - again probably as root

service gitlab start

Check gitlab is ok - as git user

$ cd /home/git/gitlab
$ bundle exec rake gitlab:env:info RAILS_ENV=production
