redis 主从复制 一主一从 2 哨兵

用于数据量不是特别大的查询业务！

版本：redis 6

系统：centos8

1，安装redis，修改配置，后台运行  

参考 https://www.cnblogs.com/chen-msg/p/13726306.html

#记得注释bind  阿里云服务器不支持

#不保护
protected-mode no
#后台运行
daemonize yes
#密码
masterauth "alb57redis79"

　　

2, 主从配置。只是在从服务器配置：

replicaof 121.196.218.72 6379

3，哨兵配置 2个都一样

protected-mode no

daemonize yes

sentinel monitor mymaster 121.196.218.71 6379 1

sentinel auth-pass mymaster "lb57redis79"

　4，启动  

systemctl需要自己编辑文件
参考 https://www.cnblogs.com/chen-msg/p/13726306.html

systemctl start redis.service
systemctl stop redis.service
systemctl restart redis.service   #重新启动服务
systemctl enable redis.service   #设置开机自启动
systemctl disable redis.service   #停止开机自启动

systemctl start redis-sentinel.service
systemctl stop redis-sentinel.service
systemctl restart redis-sentinel.service   #重新启动服务
systemctl enable redis-sentinel.service   #设置开机自启动
systemctl disable redis-sentinel.service   #停止开机自启动
