redis主从和哨兵搭建

 redis端口为 8331

sentinel端口为 8332

参考连接
https://www.cnblogs.com/MYue/p/8855888.html

1、搭建主从 没有密码

redis.conf

注意 ：从节点读写权限，自己设定是只读还是读写权限。

哨兵注意的写主节点的IP和端口

从节点配置

启用主从模式只有Redis Slave 添加一行，启动服务主从就配置好了。

slaveof 1.1.1.1 8331

2、redis有密码

redis.conf 注意

requirepass "admin.123" 　　#设置redis登录密码

masterauth "admin.123" 　　#主从认证密码，否则主从不能同步

 

vim sentinel.conf 　　#在redis的跟目录下

port 8332
daemonize yes
protected-mode no 　　#保护模式如果开启只接受回环地址的ipv4和ipv6地址链接，拒绝外部链接，而且正常应该配置多个哨兵，避免一个哨兵出现独裁情况，如果配置多个哨兵那如果开启也会拒绝其他sentinel的连接。导致哨兵配置无法生效。
logfile "/data/redis/logs/sentinel.log" 　　 #指明日志文件
dir "/data/redis/sentinel"
sentinel monitor mymaster 1.1.1.1 8331 2　　#哨兵监控的master。
sentinel down-after-milliseconds mymaster 5000 　　 #master或者slave多少时间（默认30秒）不能使用标记为down状态。
sentinel failover-timeout mymaster 9000 　　#若哨兵在配置值内未能完成故障转移操作，则任务本次故障转移失败。

sentinel auth-pass mymaster redispass 　　#如果redis配置了密码，那这里必须配置认证，否则不能自动切换

/data/redis/src/redis-sentinel /data/redis/sentinel.conf 　　#启动服务

如果有下面报错 启动命令后面要加上 --sentinel
