1、IP规划
master 192.168.0.11:6379
slave1 192.168.0.12:6379
slave2 192.168.0.13:6379
sentinel1 192.168.0.14:26379
sentinel2 192.168.0.15:26379
sentinel3 192.168.0.16:26379
2、目录规划
KumasMBA:~ kumas$ ls -l /Users/kumas/Applications/Docker/redis/cluster4sentinels/
total 0
drwxr-xr-x 2 kumas staff 68 8 9 15:28 redis01
drwxr-xr-x 2 kumas staff 68 8 9 15:29 redis02
drwxr-xr-x 2 kumas staff 68 8 9 15:29 redis03
drwxr-xr-x 2 kumas staff 68 8 9 15:28 sentinel01
drwxr-xr-x 2 kumas staff 68 8 9 15:28 sentinel02
drwxr-xr-x 2 kumas staff 68 8 9 15:28 sentinel03
3、启动master
3.1 启动一个master(注意:测试使用,没有expose对外的端口,需要则另加-p 指定)
docker run -d --name redis01 --network devnet --ip 192.168.0.11 -v /Users/kumas/Applications/Docker/redis/cluster4sentinels/redis01:/data redis:3.2-alpine --appendonly yes --port 6379
3.2 启动两个slave
docker run -d --name redis02 --network devnet --ip 192.168.0.12 -v /Users/kumas/Applications/Docker/redis/cluster4sentinels/redis02:/data redis:3.2-alpine --appendonly yes --port 6379 --slave-read-only yes --slaveof 192.168.0.11 6379
docker run -d --name redis03 --network devnet --ip 192.168.0.13 -v /Users/kumas/Applications/Docker/redis/cluster4sentinels/redis03:/data redis:3.2-alpine --appendonly yes --port 6379 --slave-read-only yes --slaveof 192.168.0.11 6379
4、启动sentinel
docker run -d --network devnet --ip 192.168.0.14 --name sentinel01 -v /Users/kumas/Applications/Docker/redis/cluster4sentinels/sentinel01:/data redis:3.2-alpine /data/sentinel.conf --sentinel
docker run -d --network devnet --ip 192.168.0.15 --name sentinel02 -v /Users/kumas/Applications/Docker/redis/cluster4sentinels/sentinel02:/data redis:3.2-alpine /data/sentinel.conf --sentinel
docker run -d --network devnet --ip 192.168.0.16 --name sentinel03 -v /Users/kumas/Applications/Docker/redis/cluster4sentinels/sentinel03:/data redis:3.2-alpine /data/sentinel.conf --sentinel
KumasMBA:~ kumas$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

01d1493ef2bf redis:3.2-alpine "docker-entrypoint..." 11 minutes ago Up 11 minutes 0.0.0.0:6379->6379/tcp redis01
ok,可以测试了。
5、附:sentinel.conf样例
port 26379
dir "/data"
logfile "/data/sentinel-01.log"
#bind 192.168.0.14
sentinel myid 203fb658bc42b4d3f5b77968b4f048e4d1df9889
sentinel monitor mymaster 192.168.0.11 6379 2
sentinel failover-timeout mymaster 60000
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
# Generated by CONFIG REWRITE
