Omnibus Gitlab + Runner 配置

本文以最小化安装为前题 (最快速安装/最少行指令/1台服务器)

安装Gitlab CE

前往https://about.gitlab.com/downloads/，并选择自己的操作系统，我自己使用的是CentOS 6，如果不是CentOS的话按照官网上的英文教程操作即可，以下代码摘取自CentOS6的安装教程。
安装需要的dependencies(postfix是发送邮件的程序，Gitlab需要发送邮件来验证注册用户的邮箱是否合法，我使用第三方SMTP服务器进行发送，你可以自行决定是否要使用postfix)

sudo yum install curl openssh-server openssh-clients postfix cronie
sudo service postfix start
sudo chkconfig postfix on
sudo lokkit -s http -s ssh

增加gitlab source并且安装

curl -sS https://packages.gitlab.com/install/repositories/gitlab/gitlab-ce/script.rpm.sh | sudo bash
sudo yum install gitlab-ce

安装完成之后运行gitlab设置程序

sudo gitlab-ctl reconfigure

设置完成之后浏览到http://localhost，设置初始密码并登入，预设管理员帐号是 root
*若在国内因为伟大的GFW而无法安装Gitlab，查看这篇文章的作法https://mirror.tuna.tsinghua.edu.cn/help/gitlab-ce/

安装Gitlab Runner

先安装Docker (Docker是一种虚拟机，Runner在执行test的时候会以一台乾净的机器的形式执行测试)

curl -sSL https://get.docker.com/ | sh

将runner添加到安装source里(自行选择对应的系统)

# For Debian/Ubuntu
curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.deb.sh | sudo bash

# For CentOS
curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-ci-multi-runner/script.rpm.sh | sudo bash

安装runner

# For Debian/Ubuntu
sudo apt-get install gitlab-ci-multi-runner

# For CentOS
sudo yum install gitlab-ci-multi-runner

执行runner configuration

sudo gitlab-ci-multi-runner register

参考如下回答

Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/ci )
自己gitlab的域名，后面加/ci
Please enter the gitlab-ci token for this runner
用管理员帐号登入自己的gitlab -> Admin Area -> Settings -> Runner -> 并且复制该页面的registration token到此
Please enter the gitlab-ci description for this runner
给这个runner一个名字，随便写，我给的是Local Shared Runner
INFO[0034] fcf5c619 Registering runner... succeeded
Please enter the executor: shell, docker, docker-ssh, ssh?
docker
Please enter the Docker image (eg. ruby:2.1):
php5.6
INFO[0037] Runner registered successfully. Feel free to start it, but if it's
running already the config should be automatically reloaded!

最后确保docker有在运行

sudo service docker start
