1.关联文档：
- 见我的Ansible学习笔记之Ansible 安装【Ubuntu16.04】
- 见其他Ansible系列，关于inventory和roles的配置
2.已有用户jiangwei，已做过SSH免密登录

其中redis-3.0.6.tar.gz为安装包，可自行去Redis官网下载。
3.1）makeredis.sh的内容如下：
cd /usr/local/redis-3.0.6
make lua hiredis linenoise
cd /usr/local/redis-3.0.6/
make install PREFIX=/opt/redis-1 MALLOC=libc
备注：makeredis2.sh和makeredis3.sh的配置同上述，仅PREFIX中的路径不同，按照运维需求中的规划目录填写即可。

备注：redis3.conf跟redis2.conf一样，除了目录不同，具体看运维需求中的redis3的目录规划
3.5）sentinel1.conf内容如下：

sentinel config-epoch mymaster 2
sentinel leader-epoch mymaster 6580
daemonize yes
logfile "/opt/redis-1/log/sentinel_log.log"
sentinel current-epoch 2
备注：sentinel2.conf、sentinel3.conf和sentinel1.conf一样，除了目录不同，具体看运维需求中的目录规划
3.6）redis1.yml内容如下：
- name: Unarchive Redis Software
unarchive: src=redis-3.0.6.tar.gz dest=/usr/local
when: ansible_default_ipv4.address == "172.16.211.67"

备注：redis2.yml和redis3.yml同redis1.yml，除了目录和IP及对应的makeredis.sh、redis.conf、sentinel.conf需要对应好。
3.7) main.yml内容如下：
- include: redis1.yml
- include: redis2.yml
- include: redis3.yml
4.redisinstall.yml内容如下：
- hosts: redis
roles:
- redis
5.编辑inventory，vi /etc/ansible/hosts，保存内容如下：
[redis]
192.168.21.67
192.168.21.68
192.168.21.69
[redis:vars]
ansible_python_interpreter=/usr/bin/python3
ansible_ssh_user=root
6.执行：ansible-playbook /opt/ansible/redisinstall.yml
7.验证：
7.1) 看角色是否符合运维需求。
/opt/redis-1/bin/redis-cli -h 192.168.21.67 -p 7000
>auth jiangwei
>info Replication
/opt/redis-2/bin/redis-cli -h 192.168.21.68 -p 7000
>auth jiangwei
>info Replication
/opt/redis-3/bin/redis-cli -h 192.168.21.69 -p 7000
>auth jiangwei
>info Replication
备注：以上也可以直接用info直接查看
7.2）查看哨兵集群状态信息：
/opt/redis-3/bin/redis-cli -h 192.168.21.67 -p 27000
>info
