1.下载redis安装包
a. wget http://download.redis.io/releases/redis-5.0.5.tar.gz
b.解压
tar -xvf redis-5.0.5.tar.gz
cd redis-5.0.5
make
make install2.搭建一主二从三哨兵配置文件
主redis配置文件
redis_master.conf
bind 192.168.3.117
port 6379
daemonize yes
dir /data/redis_master
logfile /data/redis/redis_master.log二从配置文件
redis_slave_one.conf
bind 192.168.3.117
port 6380
daemonize yes
dir /data/redis/redis_slave_one
logfile /data/redis/redis_slave_one.log
slaveof 192.168.3.117 6379
---------------------------------------
redis_slave_two.conf
bind 192.168.3.117
port 6381
daemonize yes
dir /data/redis/redis_slave_two
logfile /data/redis/redis_slave_two.log
slaveof 192.168.3.117 6379
三守护配置文件
master的守护者文件配置
bind 192.168.3.117
port 26379
sentinel myid f8c2ae332072ddbd62e778e5ffbb33fcc6fc786e
dir "/data/redis/master_sentinel"
logfile "/data/redis/sentinel/master_sentinel.log"
daemonize yes
sentinel monitor xiayu_master 192.168.1.108 6379 2
-------------------------------------
slave_one的守护者配置文件
bind 192.168.3.117
port 26380
sentinel myid d47b5dc1d048e08cd400115ead7407f276ac9dbc
dir "/data/redis/slave_one_sentinel"
logfile "/data/redis/sentinel/slave_two_sentinel.log"
daemonize yes
sentinel monitor xiayu_master 192.168.1.108 6379 2
------------------------------------
slave_two的守护者配置文件
bind 192.168.3.117
port 26381
sentinel myid bf65ebc664402c2faca875f080e1e52fd2010688
dir "/data/redis/slave_two_sentinel"
logfile "/data/redis/sentinel/slave_two_sentinel.log"
daemonize yes
sentinel monitor xiayu_master 192.168.1.108 6379 23.启动
启动主redis:
/usr/local/redis-5.0.5/src/redis-server /etc/redis/redis_master.conf
启动两从：
/usr/local/redis-5.0.5/src/redis-server /etc/redis/redis_slave_one.conf
/usr/local/redis-5.05/src/redis-server /etc/redis/redis_slave_two.conf
启动主Redis的哨兵：
/user/local/redis-5.0.5/src/redis-sentinel /etc/redis/redis_master_sentinel.conf
也可
/user/local/redis-5.0.5/src/redis-server /etc/redis/redis_master_sentinel.conf --sentinel
启动两从Redis的哨兵：
/usr/local/redis-5.0.5/src/redis-sentinel /etc/redis/redis_slave_one_sentinel.conf
/usr/local/redis-5.0.5/src/redis-sentinel /etc/redis/redis_slave_two_sentinel.conf
4.结果
5.redis配置参数说明
bind 192.168.3.117 绑定到主机ip
port 6379 服务端口号
daemonize yes/no 是否后台运行
pidfile /var/run/redis.pid 当以守护进程运行时，pid可以写入pid文件中
timeout 300 客户端连接多长时间关闭，如果为0则不断开
tcp-keepalive 0 设置客户端网络连接中断时间，为0则不检测
databases 16 默认有16个库
save 300 10 300秒内，有10个更改就保存一次
dir rdb aof备份文件放置位置
logfile /data/redis/redis_master.log 日志文件所在位置
slaveof 192.168.3.117 6379 从节点关联的主节点的ip地址及端口号
sentinel myid f8c2ae332072ddbd62e778e5ffbb33fcc6fc786e 守护redis id
sentinel monitor mymaster 192.168.3.117 6380 2 代表该哨兵监视192.168.3.117 6380的redis,当哨兵选举达到2个后，选举新的主节点
sentinel down-after-milliseconds mymaster 3000当哨兵之间互相ping，ttl大于3s后，确认不可达
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 1800006.启动脚本
