配置从库，只需要在主库基础上最后一行添加一条命令。
slaveof 192.168.19.157 6379

[root@www opt]# /opt/redis/bin/redis-cli -h 192.168.19.157 -p 6379 info Replication
# Replication
role:master
connected_slaves:1
slave0:ip=192.168.19.154,port=6379,state=online,offset=85,lag=1

配置哨兵信息。
[root@www_test opt]# cp -r /root/redis2/redis-2.8.18/sentinel.conf /opt/redis/etc/
创建哨兵临时目录，可以是空目录。
[root@www_test opt]# mkdir -p /opt/redis/sentinel-tmp
[root@www_test opt]#
[root@www_test opt]# cat /opt/redis/etc/sentinel.conf
daemonize yes
#protected-mode no
port 26379
dir "/opt/redis/sentinel-tmp"
sentinel monitor my-shaobin-test 192.168.19.157 6379 2
sentinel auth-pass my-shaobin-test sunny123
sentinel down-after-milliseconds my-shaobin-test 30000
sentinel parallel-syncs my-shaobin-test 1
sentinel failover-timeout my-shaobin-test 180000
[root@www_test opt]#

注意，哨兵配置一模一样的。
[root@www opt]# /opt/redis/bin/redis-cli -h 192.168.19.157 -p 26379 info Sentinel
# Sentinel
sentinel_masters:1
sentinel_tilt:0
sentinel_running_scripts:0
sentinel_scripts_queue_length:0
master0:name=my-shaobin-test,status=ok,address=192.168.19.157:6379,slaves=1,sentinels=2
[root@www opt]#
[root@www opt]# /opt/redis/bin/redis-cli -h 192.168.19.154 -p 26379 info Sentinel
# Sentinel
sentinel_masters:1
sentinel_tilt:0
sentinel_running_scripts:0
