理论部分不赘述，一张图说完整个流程，实操以Centos 7和root用户为例

GitLab Runner安装和配置

1、在部署机器安装CI Runner

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

2、注册Runner并绑定到CI

gitlab-ci-multi-runner register
#  url和token，在Git项目的 /runners页面可获取，step by step填写

配置信息保存在/etc/gitlab-runner/config.toml

3、Git根目录配置 .gitlab-ci.yml

stages:
  - deploy

cache:
  paths:
    - node_modules/ #部分需要重复利用又被gitignore的文件

before_script:
  - npm install
  - npm run static-prod
  - npm run vue

deploy_test:
  stage: deploy
  only:
    - dev
  script:
    - rsync -azp --delete --exclude=.git current_dir deploy_dir    
    - docker exec -d nodejs-xxx-test bash -c “pm2 restart xxx”
...other task

Docker安装和配置

1、安装Docker和启动

yum update
curl -fsSL https://get.docker.com/ | sh
systemctl enable docker.service
systemctl start docker

2、用阿里云镜像服务器加速

cp -n /lib/systemd/system/docker.service /etc/systemd/system/docker.service
sed -i "s|ExecStart=/usr/bin/docker daemon|ExecStart=/usr/bin/docker daemon --registry-mirror=<your accelerate address>|g" /etc/systemd/system/docker.service
systemctl daemon-reload
service docker restart

加速器地址，请到容器Hub服务控制台查看

3、自定义镜像

# 拉取基础镜像
docker pull centos:latest
# 交互模式运行基础镜像
docker run -i -t centos:latest
# 安装Node环境和pm2以及app目录等
$root@xxxx: curl --silent --location https://rpm.nodesource.com/setup_6.x | bash -
$root@xxxx: yum -y install nodejs
$root@xxxx: npm install pm2 -g
$root@xxxx: mkdir /app/nodejs/
$root@xxxx: exit

4、提交自定义镜像

docker commit xxxx(上面$root@部分，容器id) centos/node

5、后台运行镜像

docker run --name="nodejs-xxx-test" --restart=always -d -p 8081:3131 -v deploy_dir:/data/nodejs/ centos/node /usr/bin/bash -c 'cd /data/nodejs/;pm2 start ua.json --env test --no-daemon'

-- restart=always是让容器随docker开机启动

bash里启动pm2，需要带上--no-daemon，防止docker后台运行后，pm2退出

6、把gitlab-runner添加到docker权限组

usermod -aG docker gitlab-runner

Nginx域名绑定到容器的端口

server {
    listen  80;
    server_name xxx.xxx.com;
    access_log  /var/log/nginx/xxx.access.log;
    error_log /var/log/nginx/xxx.error.log;
    location / {
        proxy_pass http://127.0.0.1:8082;
    }
}

过程中可能因为内核设置，会出现502，不能反向代理，需要关闭

 ##如果SELinux status参数为enabled即为开启状态
/usr/sbin/sestatus -v     
...
SELinux status:                 enabled
...
##将SELINUX=enforcing改为SELINUX=disabled
vim /etc/selinux/config

setsebool -P httpd_can_network_connect 1

## 重启机器
reboot
