[很遗憾，这个教程没有真正实现安装成功]

1.安装依赖包：

　　1.1设置apt-get源　　

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak        sudo vim /etc/apt/sources.list        ====================================================        deb http://mirrors.ustc.edu.cn/ubuntu/ precise-updates main restricted        deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-updates main restricted        deb http://mirrors.ustc.edu.cn/ubuntu/ precise universe        deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise universe        deb http://mirrors.ustc.edu.cn/ubuntu/ precise-updates universe        deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-updates universe        deb http://mirrors.ustc.edu.cn/ubuntu/ precise multiverse        deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise multiverse        deb http://mirrors.ustc.edu.cn/ubuntu/ precise-updates multiverse        deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-updates multiverse        deb http://mirrors.ustc.edu.cn/ubuntu/ precise-backports main restricted universe multiverse        deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-backports main restricted universe multiverse        ======================================================

　　1.2更新源并升级已安装的软件到最新版：

sudo apt-get update && apt-get upgrade

　　1.3安装依赖包

sudo apt-get install -y wget curl gcc checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libkrb5-dev libssl-dev libmysql++-dev make cmake build-essential zlib1g-dev libicu-dev redis-server openssh-server git-core python-dev python-pip libyaml-dev postfix libpq-dev

　　1.4.安装数据库：

SQLite            sudo apt-get install -y sqlite3 libsqlite3-dev        MySQL            sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev            # Login to MySQL            $ mysql -u root -p            # Create the GitLab production database            mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;            # Create the MySQL User change $password to a real password            mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY 'test123';            # Grant proper permissions to the MySQL User            mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';        PostgreSQL            sudo apt-get install -y postgresql-9.2 postgresql-server-dev-9.2            # Connect to database server            sudo -u postgres psql -d template1            # Add a user called gitlab. Change $password to a real password            template1=# CREATE USER gitlab WITH PASSWORD '$password';            # Create the GitLab production database            template1=# CREATE DATABASE IF NOT EXISTS gitlabhq_production;            # Grant all privileges on database            template1=# GRANT ALL PRIVILEGES ON DATABASE gitlabhq_production to gitlab;            # Quit from PostgreSQL server            template1=# \q            # Try connect to new database            $ su - gitlab            $ psql -d gitlabhq_production -U gitlab

2.安装Ruby：　

　　sudo wget http://ftp.ruby-lang.org/pub/ruby/2.3/ruby-2.3.0.tar.gz    tar xfvz ruby-2.3.0.tar.gz    cd ruby-2.3.0    sudo ./configure    sudo make    sudo make install

3.安装 Gitolite

　　　3.1 为 Git 创建用户：

sudo adduser \        --system \        --shell /bin/sh \        --gecos 'git version control' \        --group \        --disabled-password \        --home /home/git \        git

　　　3.2 为 GitLab 创建用户：

# ubuntu/debian        sudo adduser --disabled-login --gecos 'gitlab system' gitlab

　　　3.3 将 gitlab 用户添加到 git 用户组：

　　　　sudo usermod -a -G git gitlab

　　　3.4 将 git 用户添加到 gitlab 用户组：

sudo usermod -a -G gitlab git

　　   3.5 生成密钥：(gitlab用户生成密钥)

　　　　 sudo -H -u gitlab ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa

　　　3.6 git用户导入gitlab用户的公钥，完成免密钥访问的配置

sudo cat /home/gitlab/.ssh/id_rsa.pub >> /home/git/.ssh/authorized_keys        sudo chmod 644 /home/git/.ssh/authorized_keys

　　　3.7 克隆 GitLab 的 Gitolite 分支源代码：

sudo -H -u git git clone -b gl-v304 https://github.com/gitlabhq/gitolite.git /home/git/gitolite

　　   3.8 安装：

cd /home/git        sudo -u git -H mkdir bin        sudo -u git sh -c 'echo -e "PATH=\$PATH:/home/git/bin\nexport PATH" >> /home/git/.profile'        sudo -u git sh -c 'gitolite/install -ln /home/git/bin'        sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub        sudo chmod 0444 /home/git/gitlab.pub        sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gitolite setup -pk /home/git/gitlab.pub"

　　　3.9 权限：

sudo chmod -R g+rwX /home/git/repositories/        sudo chown -R git:git /home/git/repositories/

　　　3.10 检查：退出并重新登录以使 git 用户组生效

# 克隆 admin 资源库以将 localhost 添加到 known_hosts        # 并且确认 gitlab 用户有权访问 gitolite        sudo -u gitlab -H git clone git@localhost:repositories/gitolite-admin.git /tmp/gitolite-admin        # 如果执行成功，你可以将其删除        sudo rm -rf /tmp/gitolite-admin

　　 备注：重要!如果你不能克隆gitolite-admin资源库，请不要继续本次安装，请根据 Trouble Shooting Guide 并且确认你已经小心的完成上文的全部步骤。

4 克隆 GitLab 源代码并安装先决条件

　　4.1 更改gem源

# sudo gem update --system 更新gem版本 sudo gem -v 查看版本        $ sudo gem sources --add https://gems.ruby-china.org/ --remove https://rubygems.org/        $ sudo gem sources -l            https://gems.ruby-china.org        # 确保只有 gems.ruby-china.org        #sudo find / -name Gemfile         #将搜索出来的三个Gemfile文件修改 source 'https://rubygems.org' -->source 'https://gems.ruby-china.org'

　　4.2 安装先决条件

sudo gem install charlock_holmes --version '0.6.8'        sudo pip install pygments        sudo gem install bundler        cd /home/gitlab

　　4.3 下载代码

# Get gitlab code. Use this for stable setup        #sudo -H -u gitlab git clone -b stable https://github.com/gitlabhq/gitlabhq.git gitlab        # Skip this for stable setup.        # Master branch (recent changes, less stable)        #sudo -H -u gitlab git clone -b master https://github.com/gitlabhq/gitlabhq.git gitlab                #我这里使用gitlab中文版的代码        sudo -H -u gitlab git clone -b master https://gitlab.com/larryli/gitlab.git gitlab

　　4.4 更改配置文件

cd gitlab        # Rename config files        sudo -u gitlab cp config/gitlab.yml.example config/gitlab.yml

　　4.5 安装数据库 gems

sudo vim /home/gitlab/gitlab/Gemfile  --> source "https://gems.ruby-china.org"        # mysql        sudo -u gitlab -H bundle install --without development test sqlite postgres  --deployment        # 或者 postgres        sudo -u gitlab -H bundle install --without development test sqlite mysql --deployment        # 或者 sqlite        sudo -u gitlab -H bundle install --without development test mysql postgres  --deployment

　　4.6 选择你希望使用的数据库

# SQLite        sudo -u gitlab cp config/database.yml.sqlite config/database.yml        # Mysql        sudo -u gitlab cp config/database.yml.mysql config/database.yml        # PostgreSQL        sudo -u gitlab cp config/database.yml.postgres config/database.yml        # 修改 config/database.yml 确认输入了正确的用户名/密码

　　4.7 初始化数据库(这里要保证上面的数据库配置文件用户名和密码对数据库可写)

　　　　sudo -u gitlab bundle exec rake gitlab:setup RAILS_ENV=production  （这里会遇到各种坑，错误见后面。大部分缺少的东西都在过程中安装了）

　　4.8 设置 GitLab hooks

sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive        sudo chown git:git /home/git/.gitolite/hooks/common/post-receive

　　4.9 确认应用程序状态：

sudo -u gitlab bundle exec rake gitlab:app:status RAILS_ENV=production        # OUTPUT EXAMPLE        Starting diagnostic        config/database.yml............exists        config/gitlab.yml............exists        /home/git/repositories/............exists        /home/git/repositories/ is writable?............YES        remote: Counting objects: 603, done.        remote: Compressing objects: 100% (466/466), done.        remote: Total 603 (delta 174), reused 0 (delta 0)        Receiving objects: 100% (603/603), 53.29 KiB, done.        Resolving deltas: 100% (174/174), done.        Can clone gitolite-admin?............YES        UMASK for .gitolite.rc is 0007? ............YES        /home/git/share/gitolite/hooks/common/post-receive exists? ............YES 　　提醒：如果所有结果都是 YES，恭喜！你可以继续进行下一步了。

5. 设置 web server

　　5.1 应用可以用下一个命令行动：

# 用于测试目的        sudo -u gitlab bundle exec rails s -e production        # 用于守护进程        sudo -u gitlab bundle exec rails s -e production -d

　　5.2 默认登录用户名及密码：

admin@local.host        5iveL!fe

6. 运行 Resque 进程(用于处理工作队列)

# 手动启动    sudo -u gitlab bundle exec rake environment resque:work QUEUE=* RAILS_ENV=production BACKGROUND=yes    # GitLab 启动脚本    sudo -u gitlab ./resque.sh    # 如果你使用 root 运行此脚本，会导致 /home/gitlab/gitlab/tmp/pids/resque_worker.pid 文件的拥有者为 root    # 将导致 resque 在下一次系统初始化中无法启动

　  6.1 自定义 Resque 使用的 Redis 连接　

如果你希望 Resque 连接到一个非标准端口号或另一台服务器上的 Redis，你可以在config/resque.yml 文件修改连接信息：            production: redis.example.com:6379

7. 我们已经拥有了一个工作正常的GitLab了，但请继续下去，有一些事情是必须完成的。

　　7.1 Unicorn

cd /home/gitlab/gitlab        sudo -u gitlab cp config/unicorn.rb.example config/unicorn.rb        sudo -u gitlab bundle exec unicorn_rails -c config/unicorn.rb -E production -D

　　7.2 Nginx

# 初次安装 Nginx        sudo apt-get install nginx        # 添加GitLab 到 nginx sites        sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/nginx/gitlab -P /etc/nginx/sites-available/        sudo ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab        # 修改 **YOUR_SERVER_IP** 与 **YOUR_SERVER_FQDN**        # 为起初的 IP 地址与准备让 GitLab 服务的域名        sudo vim /etc/nginx/sites-enabled/gitlab        # 重启 nginx:        sudo /etc/init.d/nginx restart

　　7.3 Init 脚本

在 /etc/init.d/gitlab 创建 init 脚本：            sudo update-rc.d gitlab defaults 21        现在你可以用这种方式启动/重启/停止 GitLab 服务：            sudo /etc/init.d/gitlab restart

错误集锦：

1.运行sudo -u git -H bundle install --deployment --without development test postgres aws 的时候报错 参考链接：http://stackoverflow.com/questions/27472234/an-error-occurred-while-installing-rugged
