实际中，多个sentinel、master、slave不应该在一台机器
一、准备redis(下载、编译、安装、配置目录、数据目录)
1. 下载、编译、安装
cd /opt/soft wget http://download.redis.io/releases/redis-3.0.6.tar.gz tar xzf redis-3.0.6.tar.gz cd redis-3.0.6 make make install
2. 配置目录、数据目录
cd /opt/soft/redis-3.0.6 mkdir -p data mkdir -p conf
3.建立软链接：
ln -s /opt/soft/redis-3.0.6 /opt/soft/redis
二、配置、启动Redis节点（本例子以1主2从，3个sentinel组成Redis Sentinel结构）
(1) 配置redis节点，在conf目录下添加3个(7000,7001,7002)redis-${port}.conf作为3个Redis节点的配置文件
其中7000是主,7001,7002是从
master的配置文件(7000)
port 7000 daemonize yes pidfile /var/run/redis-7000.pid logfile "7000.log" dbfilename "dump-7000.rdb" appendonly yes appendfilename "appendonly-7000.aof" dir "/opt/soft/redis/data/"
生成两个slave的配置文件(7001,7002)
sed 's/7000/7001/g' redis-7000.conf > redis-7001.conf echo "slaveof 10.10.53.159 7000" >> redis-7001.conf sed 's/7000/7002/g' redis-7000.conf > redis-7002.conf echo "slaveof 10.10.53.159 7000" >> redis-7002.conf
(2) 启动3个节点。
redis-server /opt/soft/redis/conf/redis-7000.conf redis-server /opt/soft/redis/conf/redis-7001.conf redis-server /opt/soft/redis/conf/redis-7002.conf
查看节点是否都已经启动：
[@zw_53_162 conf]# ps -ef | grep redis root 31869 1 0 22:59 ? 00:00:00 redis-server *:7000 root 31875 1 0 22:59 ? 00:00:00 redis-server *:7001 root 31885 1 0 22:59 ? 00:00:00 redis-server *:7002
查看主从关系：
[@zw_53_162 conf]# redis-cli -p 7000 info replication # Replication role:master connected_slaves:2 slave0:ip=10.10.53.159,port=7001,state=online,offset=15,lag=1 slave1:ip=10.10.53.159,port=7002,state=online,offset=15,lag=1 master_repl_offset:15 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:2 repl_backlog_histlen:14
三、启动sentinel节点:
(1). 启动3个sentinel节点(26379,26380,26381)，配置如下：
redis-sentinel-26379.conf
port 26379 daemonize yes pidfile /var/run/redis-26379.pid logfile "26379.log" dir /opt/soft/redis/data sentinel monitor mymaster 10.10.53.159 7000 2 sentinel down-after-milliseconds mymaster 30000 sentinel parallel-syncs mymaster 1 sentinel failover-timeout mymaster 180000
redis-sentinel-26380.conf, redis-sentinel-26381.conf
sed 's/26379/26380/g' redis-sentinel-26379.conf > redis-sentinel-26380.conf sed 's/26379/26381/g' redis-sentinel-26379.conf > redis-sentinel-26381.conf
(2) 启动3个sentinel节点。
redis-sentinel /opt/soft/redis/conf/redis-sentinel-26379.conf redis-sentinel /opt/soft/redis/conf/redis-sentinel-26380.conf redis-sentinel /opt/soft/redis/conf/redis-sentinel-26381.conf
查看节点是否都已经启动：
[@zw_53_162 conf]# ps -ef | grep redis-sentinel root 2949 1 0 23:09 ? 00:00:00 redis-sentinel *:26379 [sentinel] root 2955 1 0 23:09 ? 00:00:00 redis-sentinel *:26380 [sentinel] root 2961 1 0 23:09 ? 00:00:00 redis-sentinel *:26381 [sentinel]
sentinel的info信息查询：
[@zw_53_162 config]# redis-cli -p 26379 info sentinel # Sentinel sentinel_masters:1 sentinel_tilt:0 sentinel_running_scripts:0 sentinel_scripts_queue_length:0 master0:name=mymaster,status=ok,address=10.10.53.159:7000,slaves=2,sentinels=3
