步骤：
1.下载redis安装包或是上传一个下载好的压缩包，这里用的是redis-5.0.7
wget http://download.redis.io/releases/redis-5.0.7.tar.gz
2.解压编译
tar -zxvf redis-5.0.7.tar.gz
3.编译安装
切换到redis的目录下
cd redis-5.0.7
4.安装make
sudo apt-get install ubuntu-make
sudo apt-get install make
5.安装gcc
sudo apt-get install gcc
6.编译安装
make
make install prefix=/home/redis
7.创建目录
cd /home/redis
mkdir conf
mkdir log
mkdir data
mkdir temp
8.拷贝文件redis.conf和sentinel.conf
cp /usr/local/redis-5.0.7/redis.conf /home/redis/conf/redis6379.conf
cp /usr/local/redis-5.0.7/redis.conf /home/redis/conf/redis6380.conf
cp /usr/local/redis-5.0.7/redis.conf /home/redis/conf/redis6381.conf
cp /usr/local/redis-5.0.7/sentinel.conf /home/redis/conf/sentinel26379.conf
cp /usr/local/redis-5.0.7/sentinel.conf /home/redis/conf/sentinel26380.conf
cp /usr/local/redis-5.0.7/sentinel.conf /home/redis/conf/sentinel26381.conf
9.配置redis
主 6379
protected-mode yes
port 6379
daemonize yes
pidfile /var/run/redis_6379.pid
logfile /var/log/redis/redis_6379.log
dir /usr/local/redis-cluster/6379/data
slave-read-only yes
#设置访问登录密码
requirepass 123456
#从服务设置了密码需要加上
masterauth 123456
从slave 6380
protected-mode yes
port 6380
daemonize yes
pidfile /var/run/redis_6380.pid
logfile /var/log/redis/redis_6380.log
dir /usr/local/redis-cluster/6380/data
slaveof 127.0.0.1 6379
#若主服务设置了密码需要加上 ，在设置哨兵时主从之间连接需要
masterauth 123456
#从服务密码设置
requirepass 123456
从slave 6381
protected-mode yes
port 6381
daemonize yes
pidfile /var/run/redis_6381.pid
logfile /var/log/redis/redis_6381.log
dir /usr/local/redis-cluster/6381/data
slaveof 127.0.0.1 6379
#若主服务设置了密码需要加上，在设置哨兵时主从之间连接需要
masterauth 123456
#从服务密码设置
requirepass 123456
master既可以读,也可以写,而 从服务器是只可以读,不可写的.
10.哨兵配置
主 26379
protected-mode no
port 26379
dir "/usr/local/redis/temp/6379"
sentinel monitor redis1 127.0.0.1 6379 2
#若主服务设置了密码需要加上注意顺序必须在sentinel monitor下面
sentinel auth-pass mymaster 123456
sentinel down-after-milliseconds redis1 10000
sentinel failover-timeout redis1 60000
从 26380
protected-mode no
port 26380
dir "/usr/local/redis/temp/6380"
sentinel monitor redis1 127.0.0.1 6380 2
sentinel down-after-milliseconds redis1 10000
sentinel failover-timeout redis1 60000
从 26381
protected-mode no
port 26381
dir "/usr/local/redis/temp/6381"
sentinel monitor redis1 127.0.0.1 6381 2
sentinel down-after-milliseconds redis1 10000
sentinel failover-timeout redis1 60000
11.启动redis 和sentinel
./redis-server /home/redis/conf/redis6379.conf
./redis-server /home/redis/conf/redis6380.conf
./redis-server /home/redis/conf/redis6381.conf
./redis-sentinel /home/redis/conf/sentinel26379.conf
./redis-sentinel /home/redis/conf/sentinel26380.conf
./redis-sentinel /home/redis/conf/sentinel26381.conf
12.查看状态
redis-cli -h 127.0.0.1 -p 26379 -a 123456 info Sentinel
13.查看进程
ps aux | grep redis
14.可以通过redis客户端进行测试
