Ansible部署nginx＋tomcat＋jenkins

Ansible＋tomcat＋jenkins

准备环境

• 准备四台干净的机器，关闭防火墙和SELinux

• 分别给四台机器修改主机名并做解析

• 192.168.226.128 ansible
  192.168.226.129 nginx-proxy
  192.168.226.130 tomcat-jenkins1
  192.168.226.131 tomcat-jenkins2

• 在控制节点上下载ansible工具

• 在ansible的主机清单文件中配置主机组
  [host1]
  nginx-proxy
  [host2]
  tomcat-jenkins1
  tomcat-jenkins2

• 各主机与控制节点秘钥传输

• 将tomcat，jenkins包上传到控制节点

准备工作，在ansible主机上
