ansible部署redis内置集群3个节点
ansible部署redis三主三从内置集群：

执行顺序：
先找入口文件site.yml
---
- hosts: redis
gather_facts: yes
roles:
- redis
然后执行redis的角色下面的main.yml
- include: ruby.yml
- include: install_redis.yml
main.yml文件中包括2个任务，一是我们都知道在安装redis集群的时候需要先安装ruby，然后才是安装redis。
我们先看ruby.yml文件
这里采用的rvm方式安装ruby，之前已经安装过，我们把这个包给打包，到新的服务器上解压即可，配置软连接即可。

- name: unarchive_ruby
unarchive:
src: rvm.tar.gz
dest: /usr/local/
when: master is defined
tags:

- install_ruby
- name: link_ruby

dest: /usr/bin/ruby
state: link
when: master is defined
tags:
- link_ruby
- install_ruby然后就是安装redis的部分了
