SaltStack部署Redis主从实现
SaltStack部署Redis主从实现
需求：
192.168.56.11是主，192.168.56.12是从
redis监听自己的ip地址，而不是0.0.0.0
分析：
linux-node1 安装 配置 启动
linux-node2 安装 配置 启动 设置主从
# yum install redis -y
# mkdir redis/files -p
# cp /etc/redis.conf /srv/salt/prod/redis/files/
# tree
.

│ └── redis.conf
└── init.sls

# vim init.sls

# salt '*' state.sls redis.init saltenv=prod#测试单一执行sls是否成功
# netstat -tulnp|grep redis-server
tcp 0 0 192.168.56.11:6379 0.0.0.0:* LISTEN 10186/redis-server
# netstat -tulnp |grep redis-server

主从配置：
# vim master.sls
include:
- redis.init
# vim slave.sls
include:
- redis.init
slave_config:
cmd.run:
- name: redis-cli -h 192.168.56.12 slaveof 192.168.56.11 6379--->设置主从
- unless: redis-cli -h 192.168.56.12 info |grep role:slave-->判断node2是否为从，如果是就不执行设置主从
- require:
- service: redis-service
# vim /srv/salt/base/top.sls #配置top file
prod:
'linux-node1.example.com':
- lamp
- redis.master
'linux-node2.example.com':
- lamp
- redis.slave
# salt '*' state.highstate

TIPS：生产环境中，务必使用test=True进行与测试，并且目标选择一个节点进行，避免错误，影响业务的运行。
