# From 8.15 to 8.16
|
|
|
|
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
|
|
|
|
```bash
|
|
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. Update Ruby
|
|
|
|
We will continue supporting Ruby < 2.3 for the time being but we recommend you
|
|
upgrade to Ruby 2.3 if you're running a source installation, as this is the same
|
|
version that ships with our Omnibus package.
|
|
|
|
You can check which version you are running with `ruby -v`.
|
|
|
|
Download and compile Ruby:
|
|
|
|
```bash
|
|
mkdir /tmp/ruby && cd /tmp/ruby
|
|
curl --remote-name --progress https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz
|
|
echo '1014ee699071aa2ddd501907d18cbe15399c997d ruby-2.3.3.tar.gz' | shasum -c - && tar xzf ruby-2.3.3.tar.gz
|
|
cd ruby-2.3.3
|
|
./configure --disable-install-rdoc
|
|
make
|
|
sudo make install
|
|
```
|
|
|
|
Install Bundler:
|
|
|
|
```bash
|
|
sudo gem install bundler --no-ri --no-rdoc
|
|
```
|
|
|
|
### 4. Get latest code
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
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
|
|
cd /home/git/gitlab
|
|
|
|
sudo -u git -H git checkout 8-16-stable
|
|
```
|
|
|
|
OR
|
|
|
|
For GitLab Enterprise Edition:
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
sudo -u git -H git checkout 8-16-stable-ee
|
|
```
|
|
|
|
### 5. 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
|
|
|
|
# Optional: clean up old gems
|
|
sudo -u git -H bundle clean
|
|
|
|
# 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
|
|
```
|
|
|
|
**MySQL installations**: Run through the `MySQL strings limits` and `Tables and data conversion to utf8mb4` [tasks](../install/database_mysql.md).
|
|
|
|
### 6. 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
|
|
|
|
sudo -u git -H bundle exec rake "gitlab:workhorse:install[/home/git/gitlab-workhorse]" RAILS_ENV=production
|
|
```
|
|
|
|
### 7. Update gitlab-shell
|
|
|
|
```bash
|
|
cd /home/git/gitlab-shell
|
|
|
|
sudo -u git -H git fetch --all --tags
|
|
sudo -u git -H git checkout v4.1.1
|
|
```
|
|
|
|
### 8. 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
|
|
cd /home/git/gitlab
|
|
|
|
git diff origin/8-15-stable:config/gitlab.yml.example origin/8-16-stable:config/gitlab.yml.example
|
|
```
|
|
|
|
#### Git configuration
|
|
|
|
Configure Git to generate packfile bitmaps (introduced in Git 2.0) on
|
|
the GitLab server during `git gc`.
|
|
|
|
```sh
|
|
cd /home/git/gitlab
|
|
|
|
sudo -u git -H git config --global repack.writeBitmaps true
|
|
```
|
|
|
|
#### Nginx configuration
|
|
|
|
Ensure you're still up-to-date with the latest NGINX configuration changes:
|
|
|
|
```sh
|
|
cd /home/git/gitlab
|
|
|
|
# For HTTPS configurations
|
|
git diff origin/8-15-stable:lib/support/nginx/gitlab-ssl origin/8-16-stable:lib/support/nginx/gitlab-ssl
|
|
|
|
# For HTTP configurations
|
|
git diff origin/8-15-stable:lib/support/nginx/gitlab origin/8-16-stable:lib/support/nginx/gitlab
|
|
```
|
|
|
|
If you are using Apache instead of NGINX please see the updated [Apache templates].
|
|
Also note that because Apache does not support upstreams behind Unix sockets you
|
|
will need to let gitlab-workhorse listen on a TCP port. You can do this
|
|
via [/etc/default/gitlab].
|
|
|
|
[Apache templates]: https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache
|
|
[/etc/default/gitlab]: https://gitlab.com/gitlab-org/gitlab-ce/blob/8-16-stable/lib/support/init.d/gitlab.default.example#L38
|
|
|
|
#### SMTP configuration
|
|
|
|
If you're installing from source and use SMTP to deliver mail, you will need to add the following line
|
|
to config/initializers/smtp_settings.rb:
|
|
|
|
```ruby
|
|
ActionMailer::Base.delivery_method = :smtp
|
|
```
|
|
|
|
See [smtp_settings.rb.sample] as an example.
|
|
|
|
[smtp_settings.rb.sample]: https://gitlab.com/gitlab-org/gitlab-ce/blob/8-16-stable/config/initializers/smtp_settings.rb.sample#L13
|
|
|
|
#### Init script
|
|
|
|
Ensure you're still up-to-date with the latest init script changes:
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
|
|
```
|
|
|
|
For Ubuntu 16.04.1 LTS:
|
|
|
|
```bash
|
|
sudo systemctl daemon-reload
|
|
```
|
|
|
|
### 9. Start application
|
|
|
|
```bash
|
|
sudo service gitlab start
|
|
sudo service nginx restart
|
|
```
|
|
|
|
### 10. Check application status
|
|
|
|
Check if GitLab and its environment are configured correctly:
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
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:
|
|
|
|
```bash
|
|
cd /home/git/gitlab
|
|
|
|
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 (8.15)
|
|
|
|
### 1. Revert the code to the previous version
|
|
|
|
Follow the [upgrade guide from 8.14 to 8.15](8.14-to-8.15.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.
