1、配置文件：
主節點配置：
cat redis-7000.conf
port 7000
daemonize yes
pidfile /var/run/redis-7000.pid
logfile "7000.log"
dir /opt/redis/data
從節點配置：
[root@centos03ms config]# sed "s/7000/7001/g" redis-7000.conf >redis-7001.conf
[root@centos03ms config]# cat redis-7002.conf
port 7002
daemonize yes
pidfile /var/run/redis-7002.pid
logfile "7002.log"
dir /opt/redis/data
slaveof 127.0.0.1 7000
[root@centos03ms config]# cat redis-7001.conf
port 7001
daemonize yes
pidfile /var/run/redis-7001.pid
logfile "7001.log"
dir /opt/redis/data
slaveof 127.0.0.1 7000
2、啓動主從節點：
[root@centos03ms config]# redis-server redis-7000.conf
[root@centos03ms config]# redis-server redis-7001.conf
[root@centos03ms config]# redis-server redis-7002.conf
[root@centos03ms config]# ps -ef |grep redis
root 19874 1 0 00:11 ? 00:00:00 redis-server *:7000
root 19881 1 0 00:11 ? 00:00:00 redis-server *:7001
root 19885 1 0 00:11 ? 00:00:00 redis-server *:7002
root 19893 16693 0 00:11 pts/7 00:00:00 grep redis
[root@centos03ms config]#
3、配置第一個sentinel的配置文件
[root@centos03ms redis]# cp sentinel.conf ./config/sentinel.conf
[root@centos03ms redis]# cd config/
[root@centos03ms config]# cat sentinel.conf |grep -v "#" |grep -v "^$"
daemonize yes
port 26379
dir /opt/redis/data/
logfile "26379.log"
sentinel monitor mymaster 127.0.0.1 7000 2
sentinel down-after-milliseconds mymaster 30000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 180000
4、啓動第一個sentinel
[root@centos03ms config]# redis-sentinel redis-sentinel-26379.conf
[root@centos03ms config]# ps -ef |grep redis-sentinel
root 20989 1 0 00:49 ? 00:00:00 redis-sentinel *:26379 [sentinel]
root 20999 16693 0 00:49 pts/7 00:00:00 grep redis-sentinel
[root@centos03ms config]#
[root@centos03ms config]# redis-cli -p 26379
127.0.0.1:26379> set hello word

master0:name=mymaster,status=ok,address=127.0.0.1:7000,slaves=2,sentinels=1
127.0.0.1:26379>
再看下sentinel配置：
[root@centos03ms config]# cat redis-sentinel-26379.conf
daemonize yes
port 26379
dir "/opt/redis-3.0.7/data"
logfile "26379.log"
sentinel monitor mymaster 127.0.0.1 7000 2
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
sentinel known-slave mymaster 127.0.0.1 7002
# Generated by CONFIG REWRITE
sentinel known-slave mymaster 127.0.0.1 7001
sentinel current-epoch 0
[root@centos03ms config]#
5、配置第二、三個sentinel的配置文件：
[root@centos03ms config]# sed "s/26379/26380/g" redis-sentinel-26379.conf > redis-sentinel-26380.conf
[root@centos03ms config]# sed "s/26379/26381/g" redis-sentinel-26379.conf > redis-sentinel-26381.conf
[root@centos03ms config]# cat redis-sentinel-26380.conf
daemonize yes
port 26380
dir "/opt/redis-3.0.7/data"
logfile "26380.log"
sentinel monitor mymaster 127.0.0.1 7000 2
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
sentinel known-slave mymaster 127.0.0.1 7002
# Generated by CONFIG REWRITE
sentinel known-slave mymaster 127.0.0.1 7001
sentinel current-epoch 0
[root@centos03ms config]# cat redis-sentinel-26381.conf
daemonize yes
port 26381
dir "/opt/redis-3.0.7/data"
logfile "26381.log"
sentinel monitor mymaster 127.0.0.1 7000 2
sentinel config-epoch mymaster 0
sentinel leader-epoch mymaster 0
sentinel known-slave mymaster 127.0.0.1 7002
# Generated by CONFIG REWRITE
sentinel known-slave mymaster 127.0.0.1 7001
sentinel current-epoch 0
[root@centos03ms config]#
啓動二、三節點的sentinel
[root@centos03ms config]# redis-sentinel redis-sentinel-26380.conf
[root@centos03ms config]# redis-sentinel redis-sentinel-26381.conf
[root@centos03ms config]# ps -ef |grep redis-sentinel
root 20989 1 0 00:49 ? 00:00:01 redis-sentinel *:26379 [sentinel]
root 21259 1 0 00:58 ? 00:00:00 redis-sentinel *:26380 [sentinel]
root 21266 1 0 00:58 ? 00:00:00 redis-sentinel *:26381 [sentinel]
root 21273 19342 0 00:59 pts/9 00:00:00 grep redis-sentinel
[root@centos03ms config]#
驗證：
[root@centos03ms config]# redis-cli -p 26381
127.0.0.1:26381> info sentinel
# Sentinel
sentinel_masters:1
sentinel_tilt:0
sentinel_running_scripts:0
