Installation Of GitLab On Ubuntu 12.04

#Installation Of GitLab On Ubuntu/Debian  
This installation guide was created for and tested on Debian/Ubuntu operating systems. Please read doc/install/requirements.md for hardware and operating system requirements.
This is the official installation guide to set up a production server. To set up a development installation or for many other installation options please consult the installation section in the readme.
The following steps have been known to work. Please use caution when you deviate from this guide. Make sure you don't violate any assumptions GitLab makes about its environment. For example many people run into permission problems because they changed the location of directories or run services as the wrong user.
If you find a bug/error in this guide please submit a pull request following the contributing guide.

Overview
The GitLab installation consists of setting up the following components:

    1. Packages / Dependencies 
    2. Ruby 
    3. System Users 
    4. GitLab shell 
    5. Database 
    6. GitLab 
    7. Nginx 
    
1. Packages / Dependencies

sudo is not installed on Debian by default. Make sure your system is up-to-date and install it.
###run as root!

    apt-get update -y
    apt-get upgrade -y
    apt-get install sudo -y
    
Note: During this installation some files will need to be edited manually. If you are familiar with vim set it as default editor with the commands below. If you are not familiar with vim please skip this and keep using the default editor.
###Install vim and set as default editor
    sudo apt-get install -y vim
    sudo update-alternatives --set editor /usr/bin/vim.basic
Install the required packages:
    
    sudo apt-get install -y build-essential zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses5-dev libffi-dev curl git-core openssh-server redis-server checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libicu-dev
Make sure you have the right version of Python installed.
### Install Python
    sudo apt-get install -y python

### Make sure that Python is 2.5+ (3.x is not supported at the moment)
    python --version

### If it's Python 3 you might need to install Python 2 separately
    sudo apt-get install python2.7

### Make sure you can access Python via python2
    python2 --version

### If you get a "command not found" error create a link to the python binary
    sudo ln -s /usr/bin/python /usr/bin/python2

### For reStructuredText markup language support install required package:
    sudo apt-get install python-docutils
    
Note: In order to receive mail notifications, make sure to install a mail server. By default, Debian is shipped with exim4 whereas Ubuntu does not ship with one. The recommended mail server is postfix and you can install it with:

    sudo apt-get install -y postfix 
    
Then select 'Internet Site' and press enter to confirm the hostname.

2. Ruby
Remove the old Ruby 1.8 if present


    sudo apt-get remove -y ruby1.8

Download Ruby and compile it:

    mkdir /tmp/ruby && cd /tmp/ruby
    curl --progress ftp://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz | tar xz
    cd ruby-2.0.0-p247
    ./configure
    make
    sudo make install
    Install the Bundler Gem:
    sudo gem install bundler --no-ri --no-rdoc

3. System Users
Create a git user for Gitlab:


    
    sudo adduser --disabled-login --gecos 'GitLab' git


4. GitLab shell
GitLab Shell is a ssh access and repository management software developed specially for GitLab.
### Go to home directory
        

    cd /home/git

### Clone gitlab shell
    
    sudo -u git -H git clone https://github.com/gitlabhq/gitlab-shell.git
    cd gitlab-shell

### switch to right version
    
    sudo -u git -H git checkout v1.7.1
    sudo -u git -H cp config.yml.example config.yml

### Edit config and replace gitlab_url
### with something like 'http://domain.com/'
    
    sudo -u git -H editor config.yml

### Do setup
    
    sudo -u git -H ./bin/install
    
5. Database
To setup the MySQL/PostgreSQL database and dependencies please see doc        
/install/databases.md.

Setup Database

GitLab supports the following databases:

    MySQL (preferred)
    PostgreSQL

MySQL

# Install the database packages
sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

# Pick a database root password (can be anything), type it and press enter
# Retype the database root password and press enter

# Login to MySQL
mysql -u root -p

# Type the database root password

# Create a user for GitLab
# do not type the 'mysql>', this is part of the prompt
# change $password in the command below to a real password you pick
mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY '$password';

# Create the GitLab production database
mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;

# Grant the GitLab user necessary permissions on the table.
mysql> GRANT SELECT, LOCK TABLES, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';

# Quit the database session
mysql> \q

# Try connecting to the new database with the new user
sudo -u git -H mysql -u gitlab -p -D gitlabhq_production

# Type the password you replaced $password with earlier

# You should now see a 'mysql>' prompt

# Quit the database session
mysql> \q

# You are done installing the database and can go back to the rest of the installation.

PostgreSQL

# Install the database packages
sudo apt-get install -y postgresql-9.1 libpq-dev

# Login to PostgreSQL
sudo -u postgres psql -d template1

# Create a user for GitLab. (change $password to a real password)
template1=# CREATE USER git WITH PASSWORD '$password';

# Create the GitLab production database & grant all privileges on database
template1=# CREATE DATABASE gitlabhq_production OWNER git;

# Quit the database session
template1=# \q

# Try connecting to the new database with the new user
sudo -u git -H psql -d gitlabhq_production



6. GitLab
### We'll install GitLab into home directory of the user "git"
        
            cd /home/git


Clone the Source
### Clone GitLab repository
        
        sudo -u git -H git clone https://github.com/gitlabhq/gitlabhq.git gitlab

### Go to gitlab dir
        
        cd /home/git/gitlab

### Checkout to stable release
        
        
        sudo -u git -H git checkout 6-0-stable
                
Note: You can change 6-0-stable to master if you want the bleeding edge version, but never install master on a production server!
Configure it
        
        cd /home/git/gitlab

### Copy the example GitLab config
    
        sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml

### Make sure to change "localhost" to the fully-qualified domain name of your
### host serving GitLab where necessary

        sudo -u git -H editor config/gitlab.yml

### Make sure GitLab can write to the log/ and tmp/ directories
        
        sudo chown -R git log/
        sudo chown -R git tmp/
        sudo chmod -R u+rwX  log/
        sudo chmod -R u+rwX  tmp/

### Create directory for satellites
        
        sudo -u git -H mkdir /home/git/gitlab-satellites

### Create directories for sockets/pids and make sure GitLab can write to them
        sudo -u git -H mkdir tmp/pids/
        sudo -u git -H mkdir tmp/sockets/
        sudo chmod -R u+rwX  tmp/pids/
        sudo chmod -R u+rwX  tmp/sockets/

### Create public/uploads directory otherwise backup will fail
        
        sudo -u git -H mkdir public/uploads
        sudo chmod -R u+rwX  public/uploads

### Copy the example Unicorn config
    
        sudo -u git -H cp config/unicorn.rb.example config/unicorn.rb

### Enable cluster mode if you expect to have a high load instance

### Ex. change amount of workers to 3 for 2GB RAM server
        
        sudo -u git -H editor config/unicorn.rb

### Configure Git global settings for git user, useful when editing via web
###Edit user.email according to what is set in gitlab.yml
    
        sudo -u git -H git config --global user.name "GitLab"
        sudo -u git -H git config --global user.email "gitlab@localhost"
        sudo -u git -H git config --global core.autocrlf input
Important Note: Make sure to edit both gitlab.yml and unicorn.rb to match your setup.
Configure GitLab DB settings
### Mysql
    
        sudo -u git cp config/database.yml.mysql config/database.yml

or

### PostgreSQL
    
        sudo -u git cp config/database.yml.postgresql config/database.yml

##### Make sure to update username/password in config/database.yml.
##### You only need to adapt the production settings (first part).
##### If you followed the database guide then please do as follows:
##### Change 'root' to 'gitlab'
##### Change 'secure password' with the value you have given to $password
##### You can keep the double quotes around the password
        
        sudo -u git -H editor config/database.yml

### Make config/database.yml readable to git only
        
        sudo -u git -H chmod o-rwx config/database.yml
Install Gems
        
        cd /home/git/gitlab
        sudo gem install charlock_holmes --version '0.6.9.4'

### For MySQL (note, the option says "without ... postgres")
        
        sudo -u git -H bundle install --deployment --without development     test postgres aws

### Or for PostgreSQL (note, the option says "without ... mysql")
        
        sudo -u git -H bundle install --deployment --without development test mysql aws
Initialize Database and Activate Advanced Features
        sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production

### Type 'yes' to create the database.

### When done you see 'Administrator account created:'
Install Init Script
Download the init script (will be /etc/init.d/gitlab):
        
        sudo cp lib/support/init.d/gitlab /etc/init.d/gitlab
        sudo chmod +x /etc/init.d/gitlab
Make GitLab start on boot:
        sudo update-rc.d gitlab defaults 21
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
Start Your GitLab Instance

        sudo service gitlab start
 or

        sudo /etc/init.d/gitlab restart
        
Double-check Application Status
To make sure you didn't miss anything run a more thorough check with:
        
        sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

#### If you get the error and requires git upgraded version, then run the following commands:

          sudo apt-get install python-software-properties
          sudo add-apt-repository ppa:git-core/ppa
          sudo apt-get update
          sudo apt-get install git
    and,Run following command again:
          
          sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production


If all items are green, then congratulations on successfully installing GitLab! However there are still a few steps left.

7. Nginx
Note: Nginx is the officially supported web server for GitLab. If you cannot or do not want to use Nginx as your web server, have a look at the GitLab recipes.
Installation
        

        sudo apt-get install -y nginx


Site Configuration
Download an example site config:
        
        
        sudo cp lib/support/nginx/gitlab /etc/nginx/sites-available/gitlab
        sudo ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab
Make sure to edit the config file to match your setup:
#### Change YOUR_SERVER_FQDN to the fully-qualified
#### domain name of your host serving GitLab.
       
        
        sudo editor /etc/nginx/sites-available/gitlab
        
Restart
        
        sudo service nginx restart
Done!
Visit YOUR_SERVER for your first GitLab login. The setup has created an admin account for you. You can use it to log in:

        admin@local.host
        5iveL!fe
        
Important Note: Please go over to your profile page and immediately change the password, so nobody can access your GitLab by using this login information later on.
Enjoy!
