一、首先更新系统和软件包
1 . 更新软件包
# run as root!
apt-get update -y
apt-get upgrade -y
apt-get install sudo -y
2 . 配置编辑器
# Install vim and set as default editor
sudo apt-get install -y vim
sudo update-alternatives --set editor /usr/bin/vim.basic
3 . 安装ruby
curl -L --progress https://cache.ruby-lang.org/pub/ruby/2.2/ruby-2.2.3.tar.gz | tar xz
cd ruby-2.2.3
./configure --prefix=/usr --disable-install-rdoc
make
sudo apt-get autoremove ruby
sudo make install
4 . 安装Bundler Gem:
sudo gem install bundler --no-ri --no-rdoc
如果出现：
ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
sudo apt-get install zlib1g-dev
cd ext/zlib
ruby ./extconf.rb
make
make install
如果出现：
ERROR: Could not find a valid gem 'bundler' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (https://s3.amazonaws.com/production.s3.rubygems.org/latest_specs.4.8.gz)
sudo gem install --http-proxy http://代理服务器:端口 bundler --no-ri --no-rdoc
二、为gitlab创建一个git用户
sudo adduser --disabled-login --gecos 'GitLab' git
三、配置数据库
官方指南用的是PostgreSQL，不过官方也有MySQL的说明：
http://doc.gitlab.com/ce/install/database_mysql.html
# 查看版本，即检查是否安装
mysql --version
# 登陆 MySQL ，
mysql -u root -p
# 如果有密码会提示输入密码
# 下面是已经进入mysql命令模式
mysql> CREATE USER 'git'@'localhost' IDENTIFIED BY '$password';
# $password 改成创建用户的密码
# CREATE USER 'git'@'localhost' IDENTIFIED BY 'git';
# Ensure you can use the InnoDB engine which is necessary to support long indexes
# If this fails, check your MySQL config files (e.g. `/etc/mysql/*.cnf`, `/etc/mysql/conf.d/*`) for the setting "innodb = off"
mysql> SET storage_engine=INNODB;
# 设置索引模式
# 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 database
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, CREATE TEMPORARY TABLES, DROP, INDEX, ALTER, LOCK TABLES ON `gitlabhq_production`.* TO 'git'@'localhost';
# 退出mysql模式
mysql> \q
确认数据库用户是否创建成功，即再次以新用户登陆进mysql模式
# Try connecting to the new database with the new user
sudo -u git -H mysql -u git -p -D gitlabhq_production
# 会提示输入密码，输入刚才你替换的 $password
# 退出mysql模式
mysql> \q
四、安装redis
sudo apt-get install redis-server
# Configure redis to use sockets
sudo cp /etc/redis/redis.conf /etc/redis/redis.conf.orig
# Disable Redis listening on TCP by setting 'port' to 0
sed 's/^port .*/port 0/' /etc/redis/redis.conf.orig | sudo tee /etc/redis/redis.conf
# Enable Redis socket for default Debian / Ubuntu path
echo 'unixsocket /var/run/redis/redis.sock' | sudo tee -a /etc/redis/redis.conf
# Grant permission to the socket to all members of the redis group
echo 'unixsocketperm 770' | sudo tee -a /etc/redis/redis.conf
# Create the directory which contains the socket
mkdir /var/run/redis
chown redis:redis /var/run/redis
chmod 755 /var/run/redis
# 这里是直接摘录官方的步骤，下面的这步可跳过
# Persist the directory which contains the socket, if applicable
if [ -d /etc/tmpfiles.d ]; then
echo 'd /var/run/redis 0755 redis redis 10d -' | sudo tee -a /etc/tmpfiles.d/redis.conf
fi
# Activate the changes to redis.conf
sudo service redis-server restart
# Add git to the redis group
sudo usermod -aG redis git
五、安装GIT（已有可跳过）
# Install Git
sudo apt-get install -y git-core
# Make sure Git is version 1.7.10 or higher, for example 1.7.12 or 2.0.0
git --version
按照上面的提示，如果版本号小于1.7.10，请按下面的步骤更新（下面的2.4.3的源，安装后是：git version 1.9.1）
# Remove packaged Git
sudo apt-get remove git-core
# Install dependencies
sudo apt-get install -y libcurl4-openssl-dev libexpat1-dev gettext libz-dev libssl-dev build-essential
# Download and compile from source
cd /tmp
curl -L --progress https://www.kernel.org/pub/software/scm/git/git-2.4.3.tar.gz | tar xz
cd git-2.4.3/
./configure
make prefix=/usr/local all
# Install into /usr/local/bin
sudo make prefix=/usr/local install
# When editing config/gitlab.yml (Step 5), change the git -> bin_path to /usr/local/bin/git
六、gitlab源码（这里选用的是，大神汉化版，文末进行介绍）
1、clone
# We'll install GitLab into home directory of the user "git" //默认安装到/home/git 即git的用户目录
cd /home/git
# Clone GitLab repository //clonegit上的源码，这里试用了汉化版，下面的注释是原版
#sudo -u git -H git clone https://gitlab.com/gitlab-org/gitlab-ce.git -b 8-1-stable gitlab
sudo -u git -H git clone https://gitlab.com/larryli/gitlab.git
# 最后一步不要急，据说网络的原因导致很卡，看运气吧
2、配置它gitlab：
# Go to GitLab installation folder
cd /home/git/gitlab
# Copy the example GitLab config
sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml
# Update GitLab config file, follow the directions at top of file
# 这一步主要是配置邮箱和一些其他的东西，自己看需要把
sudo -u git -H editor config/gitlab.yml
# Copy the example secrets file
sudo -u git -H cp config/secrets.yml.example config/secrets.yml
sudo -u git -H chmod 0600 config/secrets.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,go-w log/
sudo chmod -R u+rwX tmp/
# Make sure GitLab can write to the tmp/pids/ and tmp/sockets/ directories
sudo chmod -R u+rwX tmp/pids/
sudo chmod -R u+rwX tmp/sockets/
# Make sure GitLab can write to the public/uploads/ directory
sudo chmod -R u+rwX public/uploads
# Change the permissions of the directory where CI build traces are stored
sudo chmod -R u+rwX builds/
# Copy the example Unicorn config
sudo -u git -H cp config/unicorn.rb.example config/unicorn.rb
# Find number of cores
nproc
# Enable cluster mode if you expect to have a high load instance
# Set the number of workers to at least the number of cores
# Ex. change amount of workers to 3 for 2GB RAM server
sudo -u git -H editor config/unicorn.rb
# Copy the example Rack attack config
sudo -u git -H cp config/initializers/rack_attack.rb.example config/initializers/rack_attack.rb
# Configure Git global settings for git user, used when editing via web editor
sudo -u git -H git config --global core.autocrlf input
# Configure Redis connection settings
sudo -u git -H cp config/resque.yml.example config/resque.yml
# Change the Redis socket path if you are not using the default Debian / Ubuntu configuration
sudo -u git -H editor config/resque.yml
上面主要是拷贝和编辑一些配置文件，基本不用改，别漏掉就行
3、下面配置数据库（请注意数据库配置的模板文件）：
# PostgreSQL 请运行下面的:
sudo -u git cp config/database.yml.postgresql config/database.yml
# MySQL 请运行下面的:
sudo -u git cp config/database.yml.mysql config/database.yml
# 一定要注意，上面的两个，只能执行一个
# 下面配置数据库 将'secure password' 替换成你设置的 $password
sudo -u git -H editor config/database.yml
# PostgreSQL and MySQL:
# Make config/database.yml readable to git only
sudo -u git -H chmod o-rwx config/database.yml
4、安装 gems （为了，方便国内的网速，可在此步前，配置淘宝的ruby服务器 https://ruby.taobao.org/ 详情进入查看）
# For PostgreSQL (note, the option says "without ... mysql")
sudo -u git -H bundle install --deployment --without development test mysql aws kerberos
# Or if you use MySQL (note, the option says "without ... postgres")
sudo -u git -H bundle install --deployment --without development test postgres aws kerberos
如果出现
Could not locate Gemfile
是因为安装的时候，没有再 /home/git/gitlab 文件下
5、安装 gitlab shell
# Run the installation task for gitlab-shell (replace `REDIS_URL` if needed):
sudo -u git -H bundle exec rake gitlab:shell:install[v2.6.6] REDIS_URL=unix:/var/run/redis/redis.sock RAILS_ENV=production
# By default, the gitlab-shell config is generated from your main GitLab config.
# You can review (and modify) the gitlab-shell config as follows:
sudo -u git -H editor /home/git/gitlab-shell/config.yml
6、初始化数据库
# Go to Gitlab installation folder
cd /home/git/gitlab
sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production
# Type 'yes' to create the database tables.
# When done you see 'Administrator account created:'
设置高级密码
sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production GITLAB_ROOT_PASSWORD=yourpassword
