From GitLab's homepage:

  GitLab offers git repository management, code reviews, issue tracking, activity feeds and wikis. Enterprises install GitLab on-premise and connect it with LDAP and Active Directory servers for secure authentication and authorization. A single GitLab server can handle more than 25,000 users but it is also possible to create a high availability setup with multiple active servers.

A demo is available at their site: GitLab demo.

## Installation

Note: If you want to use RVM refer to the article Gitlab#Running GitLab with rvm before starting with the installation
Note: This article covers installing and configuring GitLab without HTTPS at first. If needed, see #Advanced Configuration to set up SSL

Install the gitlab package from the AUR.

If you are planning to host GitLab on the same machine as its database, you need to install a database backend before installing gitlab:

- Install the mariadb and libmariadbclient packages from the official repositories and start the daemon
- Install the postgresql and libpqxx packages from the official repositories. Read PostgreSQL#Installing_PostgreSQL for more information.

In order to receive mail notifications, a mail server must be installed and configured. See the following for more information:

## Configuration

### Notes Before Configuring

The gitlab package installs GitLab's files in a manner that more closely follows standard Linux conventions rather than installing everything in `/home/git` as you are told to do by GitLab's official install guide.

After you have installed gitlab from AUR, the config file `/etc/webapps/gitlab/shell.yml` corresponds to the file `/home/git/gitlab-shell/config.yml` that is mentioned in GitLab's official install guide when installing gitlab-shell. The config file `/etc/webapps/gitlab/gitlab.yml` corresponds to the file `/home/git/gitlab/config/gitlab.yml` that is mentioned in GitLab's official install guide when configuring GitLab.

Another key difference between gitlab from AUR and the GitLab install guide is that GitLab from AUR uses the `gitlab` user with `/var/lib/gitlab` as the home folder instead of the `git` user with `/home/git` as the home folder. This keeps the `/home` area clean so it contains only real user homes.

Tip: If you are familiar with the Arch Build System you can edit the PKGBUILD and relevant files to change gitlab's home directory to a place of your liking.

### Basic configuration

Open `/etc/webapps/gitlab-shell/shell.yml` and set `gitlab_url:` to the url where you intend to host GitLab (note the 'http://' and trailing slash). For example, if you will host GitLab at 'yourdomain.com', then it would look like this:

    /etc/webapps/gitlab-shell/shell.yml

    # GitLab user. git by default
    user: gitlab

    # Url to gitlab instance. Used for api calls. Should end with a slash.
    # Default: http://localhost:8080/
    # You only have to change the default if you have configured Unicorn
    # to listen on a custom port, or if you have configured Unicorn to
    # only listen on a Unix domain socket.
    gitlab_url: "http://localhost:8080/" # <<-- right here

    http_settings:
    #  user: someone
    #  password: somepass
    ...

You can leave the `gitlab_url` with default value if you will host gitlab and the web server on the same host.

Open `/etc/webapps/gitlab/gitlab.yml` and edit where needed. In the `gitlab:` section set `host:` (replacing `localhost`) to 'yourdomain.com', your fully qualified domin name (no 'http://' or trailing slash). `port:` can be confusing. This is not the port that the gitlab server (unicorn) runs on; it's the port that users will initially access through in their browser. Basically, if you intend for users to visit 'yourdomain.com' in their browser, without appending a port number to the domain name, leave `port:` as `80`. If you intend your users to type something like 'yourdomain.com:3425' into their browsers, then you'd set `port:` to `3425` (You will also have to configure your server (apache, nginx, etc) to listen on that port). Those are the minimal changes needed for a working GitLab install. The adventurous may read on in the comment and customize as needed. For example:

    /etc/webapps/gitlab/gitlab.yml

    ...
      ## GitLab settings
      gitlab:
        ## Web server settings
        host: yourdomain.com
        port: 80
        https: false
    ...

### Further configuration

#### Database backend

A Database backend will be required before Gitlab can be run. Currently GitLab supports MariaDB and PostgreSQL. By default, GitLab assumes you will use MySQL. Extra work is needed if you plan to use PostgreSQL.

Note: Do not forget to replace `your_username_here` and `your_password_here` with your chosen values in the following examples.

#### MariaDB

To set up MySQL (MariaDB) you need to create a database called `gitlabhq_production` along with a user who has full priviledges to the database. You might do it via command line as in the following example.

    mysql -u root -p

    mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production`;
    mysql> CREATE USER 'your_username_here'@'localhost' IDENTIFIED BY 'your_password_here';
    mysql> GRANT SELECT, LOCK TABLES, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'your_username_here'@'localhost';
    mysql> \q

Now try connecting to the new database with the new user to verify you did it correctly:

    mysql -u your_username_here -p -D gitlabhq_production

Next you will need to open `/etc/webapps/gitlab/database.yml` and set `username:` and `password:` for the `gitlabhq_production` database to `your_username_here` and `your_password_here`, respectively. You need not worry about the info for the `gitlabhq_development` and `gitlan_test` databases, as those are not required for our purposes (unless you are feeling adventurous at your own risk). For example:

    /etc/webapps/gitlab/database.yml

    #
    # PRODUCTION
    #
    production:
      adapter: mysql2
      encoding: utf8
      reconnect: false
      database: gitlabhq_production
      pool: 10
      username: your_username_here
      password: "your_password_here"
      # host: localhost
      # socket: /tmp/mysql.sock
    ...

It should not be set as world readable, e.g. only processes running under the `gitlab` user can read/write to it. This can be done by running the following commands:

    # chmod 600 /etc/webapps/gitlab/database.yml
    # chown gitlab:gitlab /etc/webapps/gitlab/database.yml

For more info and other ways to create/manage MySQL databases, see the MariaDB documentation, the GitLab official (generic) install guide, and phpMyAdmin.

#### PostgreSQL

Login to PostgreSQL and create the `gitlabhq_production` database with along with it's user. Remember to change `your_username_here` and `your_password_here` to the real values:

    # psql -d template1

    template1=# CREATE USER your_username_here WITH PASSWORD 'your_password_here';
    template1=# CREATE DATABASE gitlabhq_production OWNER your_username_here;
    template1=# \q

Try connecting to the new database with the new user to verify it works:

    # psql -d gitlabhq_production

Copy the PostgreSQL template file before configuring it (overwriting the default MySQL configuration file):

    # cp /usr/share/doc/gitlab/database.yml.postgresql /etc/webapps/gitlab/database.yml

Open the new `/etc/webapps/gitlab/database.yml` and set the values for `username:` and `password:`. For example:

    /etc/webapps/gitlab/database.yml

    #
    # PRODUCTION
    #
    production:
      adapter: postgresql
      encoding: unicode
      database: gitlabhq_production
      pool: 10
      username: your_username_here
      password: "your_password_here"
      # host: localhost
      # port: 5432
      # socket: /tmp/postgresql.sock
    ...

For our purposes (unless you know what you are doing), you do not need to worry about configuring the other databases listed in `/etc/webapps/gitlab/database.yml`. We only need to set up the production database to get GitLab working.

Finally, open `/usr/lib/systemd/system/gitlab.target` change all instances of `mysql.service` to `postgresql.service`. For example:

The factual accuracy of this article or section is disputed.

Reason: See systemd#Editing provided unit files for the correct way. (Discuss)

    /usr/lib/systemd/system/gitlab.target

    ...
    [Unit]
    Description=GitLab - Self Hosted Git Management
    Requires=redis.service postgresql.service
    After=redis.service postgresql.service syslog.target network.target

    [Install]
    WantedBy=multi-user.target

#### Firewall

If you want to give direct access to your Gitlab installation through a iptables firewall you have to the following ACCEPT rule. Change "your_gitlab_port" to your chosen port from above (here we give access to all clients within 192.168.1.0/24 network):

    # iptables -A tcp_inbound -p TCP -s 192.168.1.0/24 --destination-port your_gitlab_port -j ACCEPT

If you are behind a router, do not forget to forward this port to the running GitLab server host, too.

#### Satellites access

The folder `satellites` should have the following permissions set:

    # chmod 750 /var/lib/gitlab/satellites

#### Initialize Gitlab database

Start the Redis server before we create the database:

    # systemctl start redis
    # systemctl enable redis

Now you have to install bundler and the required gems with:

    # sudo -u gitlab -H gem install bundler
    # cd /usr/share/webapps/gitlab
    # sudo -u gitlab -H bundle install

Then, initialize the database and activate advanced features:

    # cd /usr/share/webapps/gitlab
    # sudo -u gitlab bundle exec rake gitlab:setup RAILS_ENV=production

Finally, Compile assets.(If you didn't do it,you won't receive data on user/sign_in pages)

    # cd /usr/share/webapps/gitlab
    # sudo -u gitlab -H bundle exec rake assets:precompile RAILS_ENV=production

#### Configure Git User

    # cd /usr/share/webapps/gitlab
    # sudo -u gitlab -H git config --global user.name  "GitLab"
    # sudo -u gitlab -H git config --global user.email "example@example.com"

This must match the `user` and `email_from` defined in `/usr/share/webapps/gitlab/config/gitlab.yml`

#### Adjust modifier bits

(The gitlab check won't pass if the user and group ownership isn't configured properly)

    # chmod -R ug+rwX,o-rwx /path/to/repos/
    # chmod -R ug-s /path/to/repos
    # find /path/to/repos/ -type d -print0 | xargs -0 chmod g+s

## Start and test GitLab

With the following commands we check if the steps we followed so far are configured properly.

    $ cd /usr/share/webapps/gitlab
    $ sudo -u gitlab bundle exec rake gitlab:env:info RAILS_ENV=production
    $ sudo -u gitlab bundle exec rake gitlab:check RAILS_ENV=production

Note: These gitlab:env:info and gitlab:check commands will show a fatal error related to git. This is OK.

    $ sudo -u gitlab bundle exec rake gitlab:env:info RAILS_ENV=production

    fatal: Not a git repository (or any of the parent directories): .git

Make systemd see your new daemon unit files:

    $ systemctl daemon-reload

After starting the database backend (in this case MySQL), we can start GitLab with its webserver (Unicorn):

    $ systemctl start redis mysqld gitlab-sidekiq gitlab-unicorn

Replace `mysqld` with `postgresql` in the above command if you are using PostgreSQL.

To automatically launch GitLab at startup, run:

    $ systemctl enable gitlab.target gitlab-sidekiq gitlab-unicorn

Now test your GitLab instance by visiting http://localhost:8080 or http://yourdomain.com and login with the default credentials:

    username: root
    password: 5iveL!fe

Note: If your browser runs not on the machine where gitlab is running, modify your unicorn.rb in order to be able to test your setup without the use of a proxy. The corresponding line looks like this:

    listen "127.0.0.1:8080, :tcp_nopush => true

you should replace that with:

    listen "examle.yourhost.com:8080, :tcp_nopush => true

GitLab should now be up and running.

## Advanced Configuration

### HTTPS/SSL

#### Change GitLab configs

Modify `/etc/webapps/gitlab/shell.yml` so the url to your GitLab site starts with `https://`. Modify `/etc/webapps/gitlab/gitlab.yml` so that `https:` setting is set to `true`.

#### Configure HTTPS server of choice

##### Apache

This article is a stub.

Notes: info needed (Discuss)

##### Node.js

You can easily set up an http proxy on port 443 to proxy traffic to the GitLab application on port 8080 using http-master for Node.js. After you have creates your domain's OpenSSL keys and have gotten you CA certificate (or self signed it), then go to https://github.com/CodeCharmLtd/http-master to learn how easy it is to proxy requests to GitLab using HTTPS. http-master is built on top of node-http-proxy.

### Web server configuration

If you want to integrate Gitlab into a running web server instead of using its build-in http server Unicorn, then follow these instructions.

#### Nginx and unicorn

Install nginx from the official repositories.

Nginx gitlab configuration needs to be copied to nginx configuration directories.

If you installed GitLab from AUR, do:

    # cp /usr/share/webapps/gitlab/lib/support/nginx/gitlab /etc/nginx/sites-available

Then edit `/etc/nginx/sites-available/gitlab` and change all path starting from `/home/git/gitlab` to `/usr/share/webapps/gitlab` (there are three occurences) and change the `proxy_pass` setting to the url you set in `/etc/webapps/gitlab/shell.yml`, e.g. (for default setting)

       proxy_pass http://localhost:8080;

If you did not use AUR, you need to copy `/lib/support/nginx/gitlab` to `/etc/nginx/sites-available/`.

Run these commands to setup nginx:

    # ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab

Edit `/etc/nginx/sites-enabled/gitlab` and change YOUR_SERVER_IP and YOUR_SERVER_FQDN to the IP address and fully-qualified domain name of the host serving Gitlab.

Make sure the following line exists at the end of the `http` block in `/etc/nginx/nginx.conf`:

    include sites-enabled/*;

Restart gitlab.target, resque.service and nginx.service.

#### Apache and unicorn

Install apache from the official repositories.

##### Configure Unicorn

Note: If the default path is not `/home/git` for your installation, change the below path accordingly

As the official installation guide instructs, copy the unicorn configuration file:

    # sudo -u git -H cp /home/git/gitlab/config/unicorn.rb.example /home/git/gitlab/config/unicorn.rb

Now edit `config/unicorn.rb` and add a listening port by uncommenting the following line:

    listen "127.0.0.1:8080"

Tip: You can set a custom port if you want. Just remember to also include it in Apache's virtual host. See below.

##### Create a virtual host for Gitlab

Create a configuration file for Gitlab’s virtual host and insert the lines below adjusted accordingly. For the ssl section see LAMP#SSL. If you do not need it, remove it. Notice that the SSL virtual host needs a specific IP instead of generic. Also if you set a custom port for Unicorn, do not forget to set it at the BalanceMember line.

You can use these examples to get you started.

##### Enable host and start unicorn

Enable your Gitlab virtual host and reload Apache:

    /etc/httpd/conf/httpd.conf

     Include /etc/httpd/conf/extra/gitlab.conf

Finally start unicorn:

    # systemctl start gitlab-unicorn

### Redis

Using a Redis setup different from default (e.g. different address, port, unix socket) requires the environment variable REDIS_URL to be set accordingly for unicorn. This can be achieved by extending the systemd service file. Create a file /etc/systemd/system/gitlab-unicorn.service.d/redis.conf that injects the REDIS_URL environment variable:

    [Service]
    Environment=REDIS_URL=unix:///run/gitlab/redis.sock

## Useful Tips

### Fix Rake Warning

When running rake tasks for the gitlab project, this error will occur: `fatal: Not a git repository (or any of the parent directories): .git`. This is a bug in bundler, and it can be safely ignored. However, if you want to git rid of the error, the following method can be used:

    # cd /usr/share/webapps/gitlab
    # sudo -u gitlab git init
    # sudo -u gitlab git commit -m "initial commit" --allow-empty

### Hook into /var

    # mkdir -m700 /var/log/gitlab /var/tmp/gitlab
    # chown gitlab:gitlab /var/log/gitlab /var/tmp/gitlab
    # sudo -u gitlab -i
    # cd ~/gitlab
    # d=log; mv $d/* /var/$d/gitlab; rm -f $d/.gitkeep; rm -r $d && ln -s /var/$d/gitlab $d
    # d=tmp; mv $d/* /var/$d/gitlab; rm -f $d/.gitkeep; rm -r $d && ln -s /var/$d/gitlab $d

### Hidden options

    rake setup                                    # GITLAB | Setup gitlab db

### Backup and restore

Create a backup of the gitlab system:

    # sudo -u gitlab -H rake RAILS_ENV=production gitlab:backup:create

Restore the previously created backup file `/home/gitlab/gitlab/tmp/backups/20130125_11h35_1359131740_gitlab_backup.tar`:

    # sudo -u gitlab -H rake RAILS_ENV=production gitlab:backup:restore BACKUP=/home/gitlab/gitlab/tmp/backups/20130125_11h35_1359131740

Note: Backup folder is set in `config/gitlab.yml`. GitLab backup and restore is documented here.

### Migrate from sqlite to mysql

Get latest code as described in #Update_Gitlab. Save data.

    # cd /home/gitlab/gitlab
    # sudo -u gitlab bundle exec rake db:data:dump RAILS_ENV=production

Follow #Mysql instructions and then setup the database.

    # sudo -u gitlab bundle exec rake db:setup RAILS_ENV=production

Finally restore old data.

    # sudo -u gitlab bundle exec rake db:data:load RAILS_ENV=production

### Running GitLab with rvm

To run gitlab with rvm first you have to set up an rvm:

     curl -L https://get.rvm.io | bash -s stable --ruby=1.9.3

Note: Version 1.9.3 is currently recommended to avoid some compatibility issues.

For the complete installation you will want to be the final user (e.g. `git`) so make sure to switch to this user and activate your rvm:

     su - git
     source "$HOME/.rvm/scripts/rvm"

Then continue with the installation instructions from above. However, the systemd scripts will not work this way, because the environment for the rvm is not activated. The recommendation here is to create to separate shell scripts for `puma` and `sidekiq` to activate the environment and then start the service:

    gitlab.sh

    #!/bin/sh
    source `/home/git/.rvm/bin/rvm 1.9.3 do rvm env --path`
    RAILS_ENV=production bundle exec puma -C "/home/git/gitlab/config/puma.rb"

    sidekiq.sh

    #!/bin/sh
    source `/home/git/.rvm/bin/rvm 1.9.3 do rvm env --path`
    case $1 in
        start)
            bundle exec rake sidekiq:start RAILS_ENV=production
            ;;
        stop)
            bundle exec rake sidekiq:stop RAILS_ENV=production
            ;;
        *)
            echo "Usage $0 {start|stop}"
    esac

Then modify the above systemd files so they use these scripts. Modify the given lines:

    gitlab.service

### Sending mails from Gitlab via SMTP

You might want to use a gmail (or other mail service) to send mails from your gitlab server. This avoids the need to install a mail daemon on the gitlab server.

Adjust `smtp_settings.rb` according to your mail server settings:

    /usr/share/webapps/gitlab/config/initializers/smtp_settings.rb

    if Rails.env.production?
      Gitlab::Application.config.action_mailer.delivery_method = :smtp

      Gitlab::Application.config.action_mailer.smtp_settings = {
        address:              'smtp.gmail.com',
        port:                 587,
        domain:               'gmail.com',
        user_name:            'username@gmail.com',
        password:             'application password',
        authentication:       'plain',
        enable_starttls_auto: true
      }
    end

Gmail will reject mails received this way (and send you a mail that it did). You will need to disable secure authentication (follow the link in the rejection mail) to work around this. The more secure approach is to enable two-factor authentication for username@gmail.com and to set up an application password for this configuration file.

## Troubleshooting

Sometimes things may not work as expected. Be sure to visit the Trouble Shooting Guide.

### HTTPS is not green (gravatar not using https)

Redis caches gravatar images, so if you have visited your GitLab with http, then enabled https, gravatar will load up the non-secure images. You can clear the cache by doing

    cd /usr/share/webapps/gitlab; bundle exec rake cache:clear

as the gitlab user.
