准备就绪，开始编写ansible playbook脚本实现静态网页远程部署，打开Git bash命令行，将之前创建好的ansible-playbook-repo仓库clone到本地：

返回到Jenkins web管理页，点击“New 任务”
添加描述
添加Git仓库（该仓库地址即为上述配置的ansible-playbook-repo的仓库地址）
参数化构建过程
添加构建步骤
在执行shell弹出的输入框内输入以下内容
#/bin/sh set +x source /home/deploy/.py3-a2.5-env/bin/activate source /home/deploy/.py3-a2.5-env/ansible/hacking/env-setup -q cd $WORKSPACE/nginx_playbooks ansible --version ansible-playbook --version ansible-playbook -i inventory/$deploy_env ./deploy.yml -e project=nginx -e branch=$branch -e env=$deploy_env
点击“Save”，然后点击“Build with Parameters”，在右侧下拉列表中选择dev，点击“Build”
查看输出信息
验证目标主机是否部署成功，在浏览器输入test.exmaple.com查看
前提是保证本地windows主机下的C:\Windows\System32\drivers\etc\hosts文件中末尾有如下对应关系
192.168.244.130 gitlab.example.com 192.168.244.131 jenkins.example.com 192.168.244.132 ansible.example.com 192.168.244.133 test.example.com
可以看到已经成功部署~
