ansible部署redis三主三从内置集群：

目录文件解释：

    └── site.yml
    
    6 directories, 19 files

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:
        - unarchive_ruby
        - install_ruby
    
    
    
    - name: link_ruby
      file:
        src: /usr/local/rvm/archives/rvm-1.29.8/rubies/ruby-2.4.6/bin/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

[root@wyl01 redis_inner3_cluster]# cat roles/redis/tasks/install_redis.yml
