Docker部署redis主从+读写分离+哨兵
前段时间给第三方部署了redis主从+读写分离+哨兵集群环境，开发想验证程序代码的稳定性，需要在测试环境搭建一套该redis系统，便用Docker持久化部署一套即可，用完即删！
一、规划
|
hostname
|
ip
|
port
|
server
|
|
master.redis
|
172.18.215.10
|
56379、46379
|
redis(master)(sentinel)
|
|
slave1.redis
|
172.18.215.15
|
56379、46379
|
redis(slave)(sentinel)
|
|
slave2.redis
|
172.18.215.16
|
56379、46379
|
redis(slave)(sentinel)
|
[root@dev templates]# tree /data/redis_test/
/data/redis_test/

└── sentinel.conf
二、redis集群（三台服务器一样的）
redis.conf
bind 0.0.0.0 protected-mode no port 56379 tcp-backlog 511 timeout 0 tcp-keepalive 300 daemonize no supervised no pidfile /var/run/redis_6379.pid loglevel verbose logfile stdout databases 256 always-show-logo yes save 900 1 save 300 10 save 60 10000 stop-writes-on-bgsave-error yes rdbcompression yes rdbchecksum yes dbfilename dump.rdb dir ./ requirepass 123456 masterauth 123456 replica-serve-stale-data yes replica-read-only yes repl-diskless-sync no repl-diskless-sync-delay 5 repl-disable-tcp-nodelay no replica-priority 100 maxmemory 2GB lazyfree-lazy-eviction no lazyfree-lazy-expire no lazyfree-lazy-server-del no replica-lazy-flush no appendonly yes appendfilename "appendonly.aof" appendfsync everysec no-appendfsync-on-rewrite no auto-aof-rewrite-percentage 100 auto-aof-rewrite-min-size 64mb aof-load-truncated yes aof-use-rdb-preamble yes lua-time-limit 5000 slowlog-log-slower-than 10000 slowlog-max-len 128 latency-monitor-threshold 0 notify-keyspace-events "" hash-max-ziplist-entries 512 hash-max-ziplist-value 64 list-max-ziplist-size -2 list-compress-depth 0 set-max-intset-entries 512 zset-max-ziplist-entries 128 zset-max-ziplist-value 64 hll-sparse-max-bytes 3000 stream-node-max-bytes 4096 stream-node-max-entries 100 activerehashing yes client-output-buffer-limit normal 0 0 0 client-output-buffer-limit replica 256mb 64mb 60 client-output-buffer-limit pubsub 32mb 8mb 60 hz 10 dynamic-hz yes aof-rewrite-incremental-fsync yes rdb-save-incremental-fsync yes slaveof 172.18.215.10 56379 slave-serve-stale-data yes slave-read-only yes #--------master.redis这台服务器不需要上面三行-------------# min-replicas-to-write 1 min-replicas-max-lag 10
# docker run -d --privileged=true -p 56379:56379 -v /data/redis_test/redis.conf:/etc/redis/redis.conf -v /data/redis_test/data:/data --name redis_test redis:5.0.12 redis-server /etc/redis/redis.conf --appendonly yes
三、哨兵集群（三台服务器一样的）
sentinel.conf
port 46379 dir "/data" logfile "sentinel-46379.log" sentinel deny-scripts-reconfig yes sentinel monitor mymaster 172.18.215.10 56379 2 sentinel auth-pass mymaster 123456 sentinel down-after-milliseconds mymaster 10000 sentinel failover-timeout mymaster 60000
# docker run -d -p 46379:46379 -v /data/redis_test/sentinel.conf:/etc/redis/sentinel.conf -v /data/redis_test/data:/data --name sentinel_test redis:5.0.12 redis-sentinel /etc/redis/sentinel.conf
四、验证
