1.安装gitlab-runner

# Linux x86-64
sudo wget -O /usr/local/bin/gitlab-runner https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64

sudo chmod +x /usr/local/bin/gitlab-runner

sudo useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

sudo gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner
sudo gitlab-runner start

以上是Linux64位环境下的安装，其他的环境参考 https://docs.gitlab.com/runner/install/linux-manually.html

2.注册gitlab-runner

sudo gitlab-runner register

他会提示你写gitlab的地址和token，这地址可以在gitlab的网页上的settings->CI/CD Pipelines 找到如图：

另外，配置好的runner可能需要开启-Run untagged jobs，同样在上图所示的页面中有一个Runners activated for this project列表，点击下面runner右侧的修改按钮，在页面中把 Run untagged jobs勾选即可

其他具体参考：https://docs.gitlab.com/runner/register/index.html

3.在项目根目录中添加 .gitlab-ci.yml 如下：

# 提交dev分支时触发
dev job:
  only:
    - dev
  script: 
    - echo 'dev' >> ci.log

# 提交test分支时触发
test job:
  only:
    - test
  script: 
    - ssh [email protected] -i /home/gitlab-runner/.ssh/ci_key << ssh2
    - date >> ci.log
    - cd /home/ubuntu/first_project/
    - git checkout test
    - git pull origin test
    - ssh2

# 提交master分支时触发
master job:
  only:
    - master
  script: 
    - ssh [email protected] -i /home/gitlab-runner/.ssh/ci_key << ssh2
    - date >> ci.log
    - cd /home/ubuntu/first_project/
    - git checkout master
    - git pull origin master
    - ssh2
    

然后，本地提交代码后runner就会执行.yml里相关脚本
