1.gitlab服务器搭建

1.1 安装依赖软件

sudo yum install -y git vim gcc glibc-static telnet
sudo yum install -y curl policycoreutils-python openssh-server
sudo systemctl enable sshd
sudo systemctl start sshd

sudo yum install postfix
sudo systemctl enable postfix
sudo systemctl start postfix

1.2 新建 /etc/yum.repos.d/gitlab-ce.repo，内容为

[gitlab-ce]
name=Gitlab CE Repository
baseurl=https://mirrors.tuna.tsinghua.edu.cn/gitlab-ce/yum/el$releasever/
gpgcheck=0
enabled=1

1.3 安装GitLab

把gitlab安装到腾讯云

sudo EXTERNAL_URL="http://gitlab.example.com" yum install -y gitlab-ce

如果不想设置域名，或者想将来再考虑，可以直接

sudo yum install -y gitlab-ce

安装完成以后，运行下面的命令进行配置

sudo gitlab-ctl reconfigure

1.4打开http://gitlab.example.com/ 修改root用户密码，然后使用root和新密码登陆。

2.搭建Gitlab CI服务器

2.1. 安装Docker

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

2.2. 安装gitlab ci runner

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

查看是否运行正常

[vagrant@gitlab-ci ~]$ sudo gitlab-ci-multi-runner status
gitlab-runner: Service is running!
[vagrant@gitlab-ci ~]$

2.3. 设置Docker权限

为了能让gitlab-runner能正确的执行docker命令，需要把gitlab-runner用户添加到docker group里, 然后重启docker和gitlab ci runner

[vagrant@gitlab-ci ~]$ sudo usermod -aG docker gitlab-runner
[vagrant@gitlab-ci ~]$ sudo service docker restart
Redirecting to /bin/systemctl restart docker.service
[vagrant@gitlab-ci ~]$ sudo gitlab-ci-multi-runner restart

2.4 注册Runner到gitlab上

[root@master chapter12]# gitlab-ci-multi-runner register
Running in system-mode.                            
                                                   
Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
http://49.234.231.49
Please enter the gitlab-ci token for this runner:

Please enter the gitlab-ci description for this runner:
[master]: 
Please enter the gitlab-ci tags for this runner (comma separated):
testzzm
Whether to run untagged builds [true/false]:
[false]: 
Whether to lock Runner to current project [true/false]:
[false]: 
Registering runner... succeeded                     runner=79s-Wdbb
Please enter the executor: shell, docker+machine, ssh, virtualbox, docker-ssh+machine, kubernetes, docker, docker-ssh, parallels:
shell
Runner registered successfully. Feel free to start it, but if it's running already the config should be automatically reloaded! 
[root@master chapter12]#

2.5新建ci的脚本文件

tags如下图所示：

我们发现pipeline成功了

3.基于一个项目演示CI

3.1创建一个java项目

git push
Counting objects: 19, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (8/8), done.
Writing objects: 100% (19/19), 1.94 KiB | 663.00 KiB/s, done.
Total 19 (delta 0), reused 0 (delta 0)
To http://49.234.231.49/root/javaci.git
 * [new branch]      master -> master
