# From 8.3 to 8.4
|
|
|
|
Make sure you view this update guide from the tag (version) of GitLab you would
|
|
like to install. In most cases this should be the highest numbered production
|
|
tag (without rc in it). You can select the tag in the version dropdown at the
|
|
top left corner of GitLab (below the menu bar).
|
|
|
|
If the highest number stable branch is unclear please check the
|
|
[GitLab Blog](https://about.gitlab.com/blog/archives.html) for installation
|
|
guide links by version.
|
|
|
|
### 1. Stop server
|
|
|
|
sudo service gitlab stop
|
|
|
|
### 2. Backup
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
sudo -u git -H bundle exec rake gitlab:backup:create RAILS_ENV=production
|
|
```
|
|
|
|
### 3. Get latest code
|
|
|
|
```bash
|
|
sudo -u git -H git fetch --all
|
|
sudo -u git -H git checkout -- db/schema.rb # local changes will be restored automatically
|
|
```
|
|
|
|
For GitLab Community Edition:
|
|
|
|
```bash
|
|
sudo -u git -H git checkout 8-4-stable
|
|
```
|
|
|
|
OR
|
|
|
|
For GitLab Enterprise Edition:
|
|
|
|
```bash
|
|
sudo -u git -H git checkout 8-4-stable-ee
|
|
```
|
|
|
|
### 4. Update gitlab-shell
|
|
|
|
```bash
|
|
cd /home/git/gitlab-shell
|
|
sudo -u git -H git fetch --all
|
|
sudo -u git -H git checkout v2.6.10
|
|
```
|
|
|
|
### 5. Update gitlab-workhorse
|
|
|
|
Install and compile gitlab-workhorse. This requires [Go 1.5](https://golang.org/dl)
|
|
which should already be on your system from GitLab 8.1.
|
|
|
|
```bash
|
|
cd /home/git/gitlab-workhorse
|
|
sudo -u git -H git fetch --all
|
|
sudo -u git -H git checkout 0.6.2
|
|
sudo -u git -H make
|
|
```
|
|
|
|
### 6. Install libs, migrations, etc.
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
# MySQL installations (note: the line below states '--without postgres')
|
|
sudo -u git -H bundle install --without postgres development test --deployment
|
|
|
|
# PostgreSQL installations (note: the line below states '--without mysql')
|
|
sudo -u git -H bundle install --without mysql development test --deployment
|
|
|
|
# Run database migrations
|
|
sudo -u git -H bundle exec rake db:migrate RAILS_ENV=production
|
|
|
|
# Clean up assets and cache
|
|
sudo -u git -H bundle exec rake assets:clean assets:precompile cache:clear RAILS_ENV=production
|
|
|
|
```
|
|
|
|
### 7. Update configuration files
|
|
|
|
#### New configuration options for `gitlab.yml`
|
|
|
|
There are new configuration options available for [`gitlab.yml`][yaml]. View them with the command below and apply them manually to your current `gitlab.yml`:
|
|
|
|
```sh
|
|
git diff origin/8-3-stable:config/gitlab.yml.example origin/8-4-stable:config/gitlab.yml.example
|
|
```
|
|
|
|
#### Init script
|
|
|
|
We updated the init script for GitLab in order to set a specific PATH for gitlab-workhorse.
|
|
|
|
```
|
|
cd /home/git/gitlab
|
|
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
|
|
```
|
|
|
|
For Ubuntu 16.04.1 LTS:
|
|
|
|
sudo systemctl daemon-reload
|
|
|
|
### 8. Start application
|
|
|
|
sudo service gitlab start
|
|
sudo service nginx restart
|
|
|
|
### 9. Check application status
|
|
|
|
Check if GitLab and its environment are configured correctly:
|
|
|
|
sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
|
|
|
|
To make sure you didn't miss anything run a more thorough check:
|
|
|
|
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
|
|
|
|
If all items are green, then congratulations, the upgrade is complete!
|
|
|
|
## Things went south? Revert to previous version (8.3)
|
|
|
|
### 1. Revert the code to the previous version
|
|
|
|
Follow the [upgrade guide from 8.2 to 8.3](8.2-to-8.3.md), except for the
|
|
database migration (the backup is already migrated to the previous version).
|
|
|
|
### 2. Restore from the backup
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
sudo -u git -H bundle exec rake gitlab:backup:restore RAILS_ENV=production
|
|
```
|
|
|
|
If you have more than one backup `*.tar` file(s) please add `BACKUP=timestamp_of_backup` to the command above.
