# From 4.2 to 5.0
*Make sure you view this [upgrade guide from the `master` branch](../../../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
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 -L --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
```
