找了很多博客，发现基本都是Ubuntu或者Fedora上安装Gitlab的，基于CentOS的基本都有错误，这篇文章是我二周加班不断测试的成果，按照这篇文章安装，包你成功。

系统环境：CentOS 5.8 x86_64

共分几个步骤

1、安装依赖包

2、安装Ruby、bundle、Python

3、建立git用户

4、安装Gitlab-Shell

5、安装数据库

6、安装Gitlab

7、安装Nginx

一、安装依赖包

1.1、导入yum源

yum –y update

yum –y install perl*

导入epel源

rpm -ivh http://dl.fedoraproject.org/pub/epel/5/x86_64/epel-release-5-4.noarch.rpm

1.2安装依赖包

yum groupinstall "Development Tools" -y

yum install kernel-devel \
  kernel-headers \
  zlib-devel \
  libyaml-devel \
  openssl-devel \
  gdbm-devel \
  readline-devel \
  ncurses-devel \
  libffi-devel \
  git \
  curl \
  openssh-server \
  redis \
  postfix \
  libxml2-devel \
  libxslt-devel \
  perl-Time-HiRes \
  curl-devel \
  libicu-devel \
  mysql-devel -y

 

如果导入epel源后出现信息的话，那么修改/etc/yum.repos.d/epel.repo 文件

将base前的#去掉，同时将mirror前加入#,完整的如下图所示：

二、安装Ruby、Bundle和Python

2.1、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
make install

2.2、安装Bundler Gem

gem install bundler

特别注意！！！

安装好Ruby和bundle后，做如下操作，否则后面会被一堆的：

sudo: gem: command not found和

/usr/bin/env: ruby: No such file or directory, Could not locate Gemfile

给累死，切记！！！

需要做的操作：

2.3、安装Python2.7.2

按照http://tz100.me/135.html即可

三、建立Git用户

useradd -c 'GitLab' git

visudo

加入一行

git ALL=(ALL)       NOPASSWD: ALL

四、安装Gitlab-Shell

下载gitlab-shell

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

切换到适合gitlab5.1的gitlab-shell的稳定版本

cd /home/git/gitlab-shell
sudo -u git -H git checkout v1.3.0
sudo -u git -H cp config.yml.example config.yml

复制配置文件

sudo -u git -H cp config.yml.example config.yml

编辑配置文件，将里面的“gitlab_url: http://localhost/”这行修改成你的域名或者IP

注：测试时我使用的是IP

sudo -u git -H vi config.yml

我的如下图所示：

此处需要注意的是：URL最后面的/不要去掉！

安装gitlab-shell

sudo -u git -H ./bin/install

安装成果的界面如下：

五、建立数据库（基于mysql）

yum install mysql mysql-devel mysql-server -y

启动mysql并设置密码

service mysqld start
mysqladmin -u root password '你自己的密码'

连接到mysql进行数据库设置

mysql -u root -p

==

mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY 'gitlab';
mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';
mysql> \q

测试连接

[root@mytest123 gitlab-shell]# sudo -u git -H mysql -u gitlab -p -D gitlabhq_production
Enter password:

mysql> \q

六、安装Gitlab

下载源码并切换到5.1的稳定版本

cd /home/git
sudo -u git -H git clone https://github.com/gitlabhq/gitlabhq.git gitlab
cd /home/git/gitlab
sudo -u git -H git checkout 5-1-stable

进行配置

cd /home/git/gitlab
sudo -u git -H cp config/gitlab.yml.example config/gitlab.yml

编辑gitlab.yml文件，将里面的    host: localhost修改成你的域名或者IP（我使用的是IP），如图

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

赋予GIT用户所需的GITLAB的目录和权限

[root@mytest123 gitlab]# sudo chown -R git -R log  
[root@mytest123 gitlab]# sudo chown -R git -R tmp
[root@mytest123 gitlab]# sudo chmod -R u+rwX  log/
[root@mytest123 gitlab]# sudo chmod -R u+rwX  tmp/

建立satellites目录

# sudo -u git -H mkdir /home/git/gitlab-satellites

建立PID目录等并赋权

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/

建立upload目录，不建立的话backup功能会失败

sudo -u git -H mkdir public/uploads
sudo chmod -R u+rwX  public/uploads

复制PUma配置文件

sudo -u git -H cp config/puma.rb.example config/puma.rb

复制数据库配置文件并编辑修改此文件中的用户名和密码为刚才建立的数据库用户和密码

sudo -u git cp config/database.yml.mysql config/database.yml
sudo -u git -H vi config/database.yml

如图所示：

安装所需的Gems

cd /home/git/gitlab
sudo gem install charlock_holmes --version '0.6.9'
sudo -u git -H bundle install --deployment --without development test postgres

bundle install会安装很多依赖包，耐心等待就是了，给出二张截图

配置GIT用户的全局变量

sudo -u git -H git config --global user.name "GitLab"
sudo -u git -H git config --global user.email "gitlab@YOUR_DOMAIN_NAME"

启动redis

注：没明白为什么需要redis，据说高级特性需要

service redis start

初始化数据库

sudo -u git -H bundle exec rake gitlab:setup RAILS_ENV=production

安装启动脚本

curl --output /etc/init.d/gitlab https://raw.github.com/gitlabhq/gitlab-recipes/5-1-stable/init.d/gitlab

chmod +x /etc/init.d/gitlab

执行检查

sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production

如果检查没有通过的话，不要启动，先根据检查的结果来修复，操作系统的那个红色没关系

如果报

是因为redis没启动的原因，

service gitlab start启动一下再次执行检查即可

启动

sudo service mysqld start
sudo service redis start
sudo service gitlab start

附：出现前面的用户和密码的话，这一步的Gitlab安装就成功了，但是只是能用3000端口，还不能通过nginx，也就是是说不能使用gitlab-shell调用，所以还未完全调通；

如果急性子的人可以先启动调试了，但我建议你先不要启动直到nginx调试完毕

bundle exec rails s -e production

代码：

[root@mytest123 ~]# su -git
su: invalid option -- g
Try `su --help' for more information.
[root@mytest123 ~]# su - git
[git@mytest123 ~]$ cd gitlab
[git@mytest123 gitlab]$ bundle exec rails s -e production -d
/usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/runtime.rb:216: warning: Insecure world writable dir /home/git/gitlab/vendor/bundle/ruby/1.9.1/bin in PATH, mode 040777
/usr/local/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/runtime.rb:216: warning: Insecure world writable dir /home/git/gitlab/vendor/bundle/ruby/1.9.1/bin in PATH, mode 040777
=> Booting WEBrick
=> Rails 3.2.13 application starting in production on http://0.0.0.0:3000
[git@mytest123 gitlab]$

七、安装nginx

yum install nginx -y

下载gitlab的nginx配置文件

 curl --output /etc/nginx/conf.d/gitlab.conf https://raw.github.com/gitlabhq/gitlab-recipes/5-1-stable/nginx/gitlab

然后编辑这个文件，将这两行

listen YOUR_SERVER_IP:80 default_server;         # e.g., listen 192.168.1.1:80;
server_name YOUR_SERVER_FQDN;     # e.g., server_name source.example.com;

修改成你的域名或者IP，我的如下：

启动nginx，然后用域名或者IP访问，第一次报了个“502 Bad Gateway”的错误，查gitlab_err.log如下

[root@mytest123 gitlab]# tail -f /var/log/nginx/gitlab_error.log
2013/06/18 10:09:49 [crit] 4003#0: *1 stat() “/home/git/gitlab/public/” failed (13: Permission denied), client: 180.159.220.7, server: 192.161.57.96, request: “GET / HTTP/1.1″, host: “192.161.57.96″

2013/06/18 10:09:49 [crit] 4003#0: *1 stat() “/home/git/gitlab/public/favicon.ico.html” failed (13: Permission denied), client: 180.159.220.7, server: 192.161.57.96, request: “GET /favicon.ico HTTP/1.1″, host: “192.161.57.96″

主要有2处需要修改，/home/git/gitlab/目录要给权限，然后:/home/git/gitlab/tmp/sockets/gitlab.socket 这个文件也要给权限，我直接给gitlab目录777的权限

[root@mytest123 gitlab]# chmod -R 777 /home/git/gitlab/

重新启动gitlab和nginx，再次进行访问

成功，界面出来了~

通过gitlab-shell的命令行检查也成功，耶！

[root@mytest123 git]# su – git
[git@mytest123 ~]$ cd gitlab-shell/
[git@mytest123 gitlab-shell]$ ./bin/check
Check GitLab API access: OK
Check directories and files:
