docker redis 高可用

废话不多说，直接上yml文件

如果docker 不是集群模式 执行

docker swarm init  
docker stack deploy --compose-file=xxx.yml redis-sentinel

命令详解

--当客户端闲置多长时间后关闭连接，如果指定为0，表示关闭该功能
timeout 0 
--保活检测，设置为0不检测，默认为300 
tcp-keepalive 60 
--绑定的主机地址
bind 0.0.0.0 
--解决docker 部署可能存在的：由于端口或IP映射导致的无法连接的问题
slave-announce-ip 192.168.1.32
slave-announce-port 36379
-- 设置密码
requirepass password@123 
--当master服务设置了密码保护时，slav服务连接master的密码
masterauth password@123 
--设置当本机为slav服务时，设置master服务的IP地址及端口，在Redis启动时，它会自动从master进行数据同步
slaveof 192.168.1.32 36379 
--监控的IP 端口号 名称 sentinel通过投票后认为mater宕机的数量，此处为至少2个
sentinel monitor mysentinel 192.168.1.32 36379 2

--解决docker 部署可能存在的：由于端口或IP映射导致的无法连接的问题
sentinel announce-ip 192.168.1.32
sentinel announce-port 36481
--如果redis有密码需要指定密码
sentinel auth-pass mysentinel password@123
--30秒ping不通主节点的信息，主观认为master宕机
sentinel down-after-milliseconds mymaster 30000
--故障转移后重新主从复制，1表示串行，>1并行
sentinel parallel-syncs mymaster 1
--故障转移开始，三分钟内没有完成，则认为转移失败
sentinel failover-timeout mymaster 180000
