# From 3.1 to 4.0
|
|
*Make sure you view this [upgrade guide from the `master` branch](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/doc/update/3.1-to-4.0.md) for the most up to date instructions.*
|
|
|
|
## Important changes
|
|
|
|
- Support for SQLite was dropped
|
|
- Support for Gitolite 2 was dropped
|
|
- Projects are organized in namespaces
|
|
- The GitLab post-receive hook needs to be updated
|
|
- The configuration file needs to be updated
|
|
- Availability of `python2` executable
|
|
|
|
Most of projects has post-receive file as symlink to Gitolite `/home/git/.gitolite/hooks/post-receive`. But some of them may have a real file. In this case you should rewrite it with symlink to Gitolite hook.
|
|
|
|
I wrote a bash script which will do it automatically for you. Just make sure all path inside is valid for you
|
|
|
|
## 1. Stop GitLab & Resque
|
|
|
|
sudo service gitlab stop
|
|
|
|
## 2. Update GitLab
|
|
|
|
```bash
|
|
|
|
# Get latest code
|
|
sudo -u gitlab -H git fetch
|
|
sudo -u gitlab -H git checkout 4-0-stable
|
|
|
|
# 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 gitlab -H vim Gemfile
|
|
|
|
# Install gems for MySQL
|
|
sudo -u gitlab -H bundle install --without development test postgres
|
|
|
|
# Update repos permissions
|
|
sudo chmod -R ug+rwXs /home/git/repositories/
|
|
sudo chown -R git:git /home/git/repositories/
|
|
|
|
# Migrate db
|
|
sudo -u gitlab -H bundle exec rake db:migrate RAILS_ENV=production
|
|
|
|
# Enable namespaces (**Warning!** All projects in groups will be moved to subdirectories)
|
|
sudo -u gitlab -H bundle exec rake gitlab:enable_namespaces RAILS_ENV=production
|
|
|
|
```
|
|
|
|
## 3. Update post-receive hooks (Requires Gitolite v3 )
|
|
|
|
Step 1: Rewrite post-receive hook
|
|
|
|
```bash
|
|
sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive
|
|
sudo chown git:git /home/git/.gitolite/hooks/common/post-receive
|
|
```
|
|
|
|
Step 2: Update project hooks to be symlinks to the Gitolite hook
|
|
|
|
```bash
|
|
# 1. Check paths in script
|
|
sudo -u gitlab -H vim lib/support/rewrite-hooks.sh
|
|
|
|
# 2. Run script
|
|
sudo -u git -H lib/support/rewrite-hooks.sh
|
|
```
|
|
|
|
## 4. Replace config with new one
|
|
|
|
# backup old one
|
|
sudo -u gitlab -H cp config/gitlab.yml config/gitlab.yml.old
|
|
|
|
# copy new one
|
|
sudo -u gitlab -H cp config/gitlab.yml.example config/gitlab.yml
|
|
|
|
# edit it
|
|
sudo -u gitlab -H vim config/gitlab.yml
|
|
|
|
## 5. Disable ssh known_host check for own domain
|
|
|

echo "Host localhost
|
|
StrictHostKeyChecking no
|
|
UserKnownHostsFile=/dev/null" | sudo tee -a /etc/ssh/ssh_config
|
|

|
echo "Host YOUR_DOMAIN_NAME
