一、环境

系统：CentOS 7.0

二、安装淘宝源

进入yum源目录：cd /etc/yum.repos.d

备份原来的源：cp CentOS-Base.repo CentOS-Base.repo.src.bak

下载淘宝源： wget -O CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

三、安装更新包

 1、执行源更新：yum update一顿刷屏后出现如下界面：

总共需要更新1.1G，这里先选择N不更新（有需要的话可以选择Y）。

2、安装相关依赖包

[root@localhost ~]# yum -y groupinstall 'Development Tools'
[root@localhost ~]#yum -y install wget curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-ExtUtils-MakeMaker asciidoc xmlto docbook2x curl openssh-server openssh-clients postfix cronie perl-Time-HiRes perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker policycoreutils

四、安装git

删除系统默认的git，使用源码安装git

[root@localhost~]# git --version

git version 1.8.3.1

[root@localhost~]# yum remove git -y

下载源码安装包

[root@localhost ~]# wget https://www.kernel.org/pub/software/scm/git/git-2.9.4.tar.gz

[root@localhost ~]# tar -zxvf git-2.9.4.tar.gz

[root@localhost ~]# cd git-2.9.4

[root@localhost git-2.9.4]# ./configure

[root@localhost git-2.9.4]# make && make prefix=/usr/local install

[root@localhost git-2.9.4]# ln -s /usr/local/bin/git /usr/bin/

[root@localhost git-2.9.4]# git --version

git version 2.9.4

五、安装最新ruby环境

#查看系统安装的ruby版本

[root@localhost ~]# ruby -v

ruby 2.0.0p353 (2013-11-22) [x86_64-linux]

#删除系统自带的ruby环境

[root@localhost ~]# yum remove ruby -y

#安装ruby安装工具ruby-install，项目地址：https://github.com/postmodern/ruby-install#readme

[root@localhost ~] wget -O ruby-install-0.6.1.tar.gz https://github.com/postmodern/ruby-install/archive/v0.6.1.tar.gz

[root@localhost ~] tar -xzvf ruby-install-0.6.1.tar.gz

[root@localhost ~] cd ruby-install-0.6.1/

[root@localhost ruby-install-0.6.1] make install

#将ruby安装到/usr/local

[root@localhost ~] ruby-install --system ruby

[root@localhost ruby-install-0.6.1]# ln -s /usr/local/bin/ruby /usr/bin/

#查看版本

[root@localhost ~] ruby -v

ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]

安装bundler

[root@localhost ~]# gem install bundler --no-doc

Fetching: bundler-1.14.6.gem (100%)

Successfully installed bundler-1.14.6

1 gem installed

六、安装giblab

参考资料：https://about.gitlab.com/downloads/#centos7
1、启动相关服务

[root@localhost ~]# sudo systemctl enable sshd

[root@localhost ~]# sudo systemctl start sshd

[root@localhost ~]# sudo systemctl enable postfix

[root@localhost ~]# sudo systemctl start postfix

[root@localhost ~]# sudo firewall-cmd --permanent --add-service=http

[root@localhost ~]# sudo systemctl reload firewalld
2、安装gitlab

[root@localhost ~]# curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash

[root@localhost ~]# sudo yum install gitlab-ce

3、配置并启动gitlab

#修改gitlab的网页入口地址

[root@localhost ~]# vi /etc/gitlab/gitlab.rb

#找到external_url，修改成想要gitlab服务的地址。

默认地址：external_url 'http://localhost'
修改后地址：external_url 'http://192.168.81.133:8000/gitlab'

注意：端口8000不要被其他应用占用。

#配置并启动

[root@localhost ~]# cd /opt/gitlab/bin

[root@localhost bin]# sudo gitlab-ctl reconfigure

七、访问gitlab

url地址：http://192.168.81.133:8000/gitlab
默认账户为：root，首次登录时需要修改密码。
