GitLab5发布快一个月了，决定试用下，5.0最大的特性就是用GitLab-Shell取代了Gitolite，这大大降低了安装难度，不多本人在安装过程中还是越到了一些问题，所以记录下来供要安装GitLab5的朋友参考！
主要参考文档: https://github.com/gitlabhq/gitlabhq/blob/5-0-stable/doc/install/installation.md
安装步骤总览
- 安装依赖包
- 安装Ruby/RVM
- 创建Git用户
- 安装GitLab-Shell
- 配置数据库
- 安装GitLab
- 启动
安装依赖库
yum install libicu-devel mysql-devel pcre-devel
安装python,官方要求版本必须在2.5以上，而且不支持3.0,Fedora一般的版本都在2.7以上，因此直接安装源自带的即可
yum install python
安装完查看下版本
python --version
还要确保python2命令有效
python2 --version
如果提示 bash: python2: 未找到命令 ,那你需要link一下
sudo ln -s /usr/bin/python /usr/bin/python2
安装Ruby
mkdir /tmp/ruby && cd /tmp/ruby
curl --progress http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p392.tar.gz | tar xz
cd ruby-1.9.3-p392
./configure
make
sudo make install
curl -#L https://get.rvm.io | bash -s stable --ruby
默然安装ruby2.0, GitLab推荐用1.9.3
rvm install ruby-1.9.3-p392
还要安装Bundler
sudo gem install bundler
添加系统Git用户
创建一个 git 用户供GitLab使用
adduser --comment 'GitLab' git
让git用户无密码登陆
sudo chmod 644 /etc/shadow vim /etc/shadow
去掉用户的叹号
git:!!:15814:0:99999:7::: 修改为 git::15814:0:99999:7:::
加入sudo组
chmod u+w /etc/sudoers
vim /etc/sudoers
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
git ALL=(ALL) ALL #加入这行
安装GitLab Shell
切换到git用户
su - git cd ~/
克隆GitLab Shell
git clone https://github.com/gitlabhq/gitlab-shell.git
cd gitlab-shell
切换到最新的分支
git checkout v1.2.0
生产配置文件
cp config.yml.example config.yml
更改配置信息，一般就改下你部署的域名地址gitlab_url
vim config.yml
# Url to gitlab instance. Used for api calls. Should be ends with slash.
gitlab_url: "http://localhost/" #改成你的域名或者IP
安装
./bin/install
安装数据库
gitlab支持mysql和postgresql，这里以mysql为例，postgresql会比较麻烦！
切换回root用户
su - root
安装mysql及开发包
yum install -y mysql-server mysql mysql-devel
启动数据库
service mysqld start
初始化GitLab数据库
mysql -u root -p
Enter password:

测试gitlab用户连接mysql
sudo -u git -H mysql -u gitlab -p -D gitlabhq_production
安装GitLab
终于到GitLab的安装了，进入git用户
su - git
cd ~/
克隆GitLab
sudo -u git -H git clone https://github.com/gitlabhq/gitlabhq.git gitlab
cd gitlab
切换到5.0稳定分支
sudo -u git -H git checkout 5-0-stable
配置
cd /home/git/gitlab
# 用样例配置生成gitlab配置
sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml
# 更改域名
sudo -u git -H vim config/gitlab.yml
# 确保gitlab对 log/ 和 tmp/ 目录有写权限
sudo chown -R git log/
sudo chown -R git tmp/
sudo chmod -R u+rwX log/
sudo chmod -R u+rwX tmp/
# 创建附属目录
sudo -u git -H mkdir /home/git/gitlab-satellites
# 创建pids目录并确保对gitlab可写
sudo -u git -H mkdir tmp/pids/
sudo chmod -R u+rwX tmp/pids/
# 生成Unicorn配置
sudo -u git -H cp config/unicorn.rb.example config/unicorn.rb
配置GitLab DB设置
# Mysql sudo -u git cp config/database.yml.mysql config/database.yml
安装Gems
cd /home/git/gitlab
sudo gem install charlock_holmes --version '0.6.9'
# For MySQL (note, the option says "without")
bundle install --deployment --without development test postgres
初始化数据并激活高级特性
首先编辑/home/git/gitlab/config/database.yml
#
# PRODUCTION
#
production:
adapter: mysql2
encoding: utf8
reconnect: false
database: gitlabhq_production
pool: 5
username: root
password: "secure password" #更改为你mysql的root用户密码
# host: localhost
# socket: /tmp/mysql.sock
#
执行rake
bundle exec rake gitlab:setup RAILS_ENV=production
报错了，提示 Error connecting to Redis on localhost:6379 (ECONNREFUSED)
解决办法：
切到root,安装Redis
bc(command). yum install redis*
service redis start #启动redis
重新执行rake
bundle exec rake gitlab:setup RAILS_ENV=production
如果你安装最新版可能会报 /home/git/repositories/root 目录找不到，手工建上即可！
如果你看到如下信息:
...
Administrator account created:
login.........admin@local.host
password......5iveL!fe
恭喜你！你已经成功安装GitLab了！别忘了记录输出的管理用户名和密码！
启动GitLab
bundle exec rails s -e production
=> Booting WEBrick
=> Rails 3.2.13 application starting in production on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2013-04-19 15:04:41] INFO WEBrick 1.3.1
[2013-04-19 15:04:41] INFO ruby 1.9.3 (2013-02-22)
[x86_64-linux] [2013-04-19 15:04:41] INFO WEBrick::HTTPServer#start: pid=11488 port=3000
Ok,你现在可以访问GitLab了，默认端口是 @3000@， 访问 http://你的域名或IP:3000
第一访问会比较慢，因为要编译很多js和css.
哈哈！看到登陆页面了吧！
输入管理用户名和密码！开始享受GitLab吧！
