# From 4.2 to 5.0
|
|
*Make sure you view this [upgrade guide from the `master` branch](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/update/4.2-to-5.0.md) for the most up to date instructions.*
|
|
|
|
## Warning
|
|
|
|
GitLab 5.0 is affected by critical security vulnerability CVE-2013-4490.
|
|
|
|
## Important changes
|
|
|
|
- We don't use `gitlab` user any more. Everything will be moved to `git` user
|
|
- Self signed SSL certificates are not supported until GitLab 5.1
|
|
- **requires ruby1.9.3**
|
|
|
|
## 0. Stop GitLab
|
|
|
|
sudo service gitlab stop
|
|
|
|
## 1. add bash to git user
|
|
|
|
```
|
|
sudo chsh -s /bin/bash git
|
|
```
|
|
|
|
## 2. git clone gitlab-shell
|
|
|
|
```
|
|
cd /home/git/
|
|
sudo -u git -H git clone https://github.com/gitlabhq/gitlab-shell.git /home/git/gitlab-shell
|
|
```
|
|
|
|
## 3. setup gitlab-shell
|
|
|
|
```bash
|
|
# chmod all repos and files under git
|
|
sudo chown git:git -R /home/git/repositories/
|
|
|
|
# login as git
|
|
sudo su git
|
|
cd /home/git/gitlab-shell
|
|
git checkout v1.1.0
|
|
|
|
# copy config
|
|
cp config.yml.example config.yml
|
|
|
|
# change URL to GitLab instance
|
|
# ! make sure the URL ends with '/' like 'https://gitlab.example/'
|
|
vim config.yml
|
|
|
|
# rewrite hooks
|
|
./support/rewrite-hooks.sh
|
|
|
|
# check ruby version for git user ( 1.9 required!! )
|
|
# GitLab shell requires system ruby 1.9
|
|
ruby -v
|
|
|
|
# exit from git user
|
|
exit
|
|
```
|
|
|
|
## 4. Copy GitLab instance to git user
|
|
|
|
```bash
|
|
sudo cp -R /home/gitlab/gitlab /home/git/gitlab
|
|
sudo chown git:git -R /home/git/gitlab
|
|
sudo rm -rf /home/gitlab/gitlab-satellites
|
|
|
|
# if exists
|
|
sudo rm /tmp/gitlab.socket
|
|
```
|
|
|
|
## 5. Update GitLab to recent version
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
# backup current config
|
|
sudo -u git -H cp config/gitlab.yml config/gitlab.yml.old
|
|
|
|
sudo -u git -H git fetch
|
|
sudo -u git -H git checkout 5-0-stable
|
|
|
|
# replace config with recent one
|
|
sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml
|
|
|
|
# edit it
|
|
sudo -u git -H vim config/gitlab.yml
|
|
|
|
# The Modernizr gem was yanked from RubyGems. It is required for GitLab >= 2.8.0
|
|
# Edit `Gemfile` and change `gem "modernizr", "2.5.3"` to
|
|
# `gem "modernizr-rails", "2.7.1"``
|
|
sudo -u git -H vim Gemfile
|
|
|
|
# Run a bundle install without deployment to generate the new Gemfile
|
|
sudo -u git -H bundle install --without development test postgres --no-deployment
|
|
|
|
# Install libs (with deployment this time)
|
|
sudo -u git -H bundle install --without development test postgres --deployment
|
|
|
|
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
|
|
sudo -u git -H bundle exec rake gitlab:shell:setup RAILS_ENV=production
|
|
sudo -u git -H bundle exec rake gitlab:shell:build_missing_projects RAILS_ENV=production
|
|
|
|
sudo -u git -H mkdir -p /home/git/gitlab-satellites
|
|
sudo -u git -H bundle exec rake gitlab:satellites:create RAILS_ENV=production
|
|
|
|
# migrate wiki to git
|
|
sudo -u git -H bundle exec rake gitlab:wiki:migrate RAILS_ENV=production
|
|
|
|
|
|
# check permissions for /home/git/.ssh/
|
|
sudo -u git -H chmod 700 /home/git/.ssh
|
|
sudo -u git -H chmod 600 /home/git/.ssh/authorized_keys
|
|
|
|
# check permissions for /home/git/gitlab/
|
|
sudo chown -R git /home/git/gitlab/log/
|
|
sudo chown -R git /home/git/gitlab/tmp/
|
|
sudo chmod -R u+rwX /home/git/gitlab/log/
|
|
sudo chmod -R u+rwX /home/git/gitlab/tmp/
|
|
sudo -u git -H mkdir -p /home/git/gitlab/tmp/pids/
|
|
sudo chmod -R u+rwX /home/git/gitlab/tmp/pids
|
|
|
|
```
|
|
|
|
## 6. Update init.d script and Nginx config
|
|
|
|
```bash
|
|
# init.d
|
|
sudo rm /etc/init.d/gitlab
|
|
sudo curl --location --output /etc/init.d/gitlab https://raw.github.com/gitlabhq/gitlab-recipes/5-0-stable/init.d/gitlab
|
|
sudo chmod +x /etc/init.d/gitlab
|
|
|
|
# unicorn
|
|
sudo -u git -H cp /home/git/gitlab/config/unicorn.rb /home/git/gitlab/config/unicorn.rb.old
|
|
sudo -u git -H cp /home/git/gitlab/config/unicorn.rb.example /home/git/gitlab/config/unicorn.rb
|
|
|
|
# Nginx
|
|
# Replace path from '/home/gitlab/' to '/home/git/'
|
|
sudo vim /etc/nginx/sites-enabled/gitlab
|
|
sudo service nginx restart
|
|
|
|
```
|
|
|
|
## 7. Start GitLab instance
|
|
|
|
```
|
|
sudo service gitlab start
|
|
|
|
# check if unicorn and sidekiq started
|
|
# If not try to logout, also check replaced path from '/home/gitlab/' to '/home/git/'
|
|
# in Nginx, unicorn, init.d etc
|
|
ps aux | grep unicorn
|
|
ps aux | grep sidekiq
|
|
|
|
```
|
|
|
|
## 8. Check installation
|
|
|
|
|
|
```bash
|
|
# In 5-10 seconds lets check gitlab-shell
|
|
sudo -u git -H /home/git/gitlab-shell/bin/check
|
|
|
|
# Example of success output
|
|
# Check GitLab API access: OK
|
|
# Check directories and files:
|
|
# /home/git/repositories: OK
|
|
# /home/git/.ssh/authorized_keys: OK
|
|
|
|
|
|
# Now check GitLab instance
|
|
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
|
|
|
|
```
|
|
|
|
## 9. Cleanup
|
|
|
|
**If everything works as expected you can cleanup some old things**
|
|
Recommend you wait a bit and do a backup before completing the following.
|
|
|
|
```bash
|
|
# remove GitLab user from system
|
|
sudo userdel -r gitlab
|
|
|
|
cd /home/git
|
|
|
|
# cleanup .profile
|
|
## remove text from .profile added during gitolite installation:
|
|
## PATH=\$PATH:/home/git/bin
|
|
## export PATH
|
|
## to see what a clean .profile for new users on your system would look like see /etc/skel/.profile
|
|
sudo -u git -H vim .profile
|
|
|
|
# remove gitolite
|
|
sudo rm -R bin
|
|
sudo rm -Rf gitolite
|
|
sudo rm -R .gitolite
|
|
sudo rm .gitolite.rc
|
|
sudo rm -f gitlab.pub
|
|
sudo rm projects.list
|
|
|
|
# reset tmp folders
|
|
sudo service gitlab stop
|
|
cd /home/git/gitlab
|
|
sudo rm -R tmp
|
|
sudo -u git -H mkdir tmp
|
|
sudo chmod -R u+rwX tmp/
|
|
|
|
# create directory for pids, make sure GitLab can write to it
|
|
sudo -u git -H mkdir tmp/pids/
|
|
sudo chmod -R u+rwX tmp/pids/
|
|
|
|
# if you are already running a newer version of GitLab check that installation guide for other tmp folders you need to create
|
|
|
|
# reboot system
|
|
sudo reboot
|
|
|
|
# login, check that GitLab is running fine
|
|
cd /home/git/gitlab
|
|
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
|
|
```
