1：由于服务器优先，只能在同一台服务器搭建2个Redis，2个Redis Sentinel，实现Redis的集群
2：Linux上下载Redis，并安装和配置
下载执行一下命令：
$ wget http://download.redis.io/releases/redis-6.0.10.tar.gz
解压下载的Redis：
$ tar xzf redis-6.0.10.tar.gz
进入解压的文件，并进行编译:
$ cd redis-6.0.10
$ make
好像不需要安装了，那就不执行按照的命令了
3：修改Redis的配置文件
主配置修改的涉及到内容：
bind 127.0.0.1 -::1
protected-mode yes
daemonize yes
port 6380
appendonly yes
pidfile "/var/run/redis_6380.pid"
logfile "/var/log/redis_6380.log"
dir "/var/lib/redis_6380"
save 60 1
从库的设置：
bind 127.0.0.1 -::1
protected-mode yes
daemonize yes
port 6381
appendonly yes
pidfile "/var/run/redis_6381.pid"
logfile "/var/log/redis_6381.log"
dir "/var/lib/redis_6381"
save 60 1
replicaof 127.0.0.1 6380
4：然后启动Redis
主的，redis-6380 目录下 ./src/redis-server redis_6380.conf
从的，redis-6381 目录下 ./src/redis-server redis_6381.conf
5：搭建配置Redis sentinel
搭建主的配置 ：
主要的配置：
port 26380
daemonize yes
pidfile "/var/run/redis-sentinel.pid"
logfile "/usr/local/soft/redis-6380/tmp/26380.log"
loglevel debug
dir "/usr/local/soft/redis-6380/tmp"
sentinel monitor mymaster_26380 127.0.0.1 6381 2
默认的配置
acllog-max-len 128
sentinel down-after-milliseconds mymaster_26380 5000
sentinel failover-timeout mymaster_26380 15000
sentinel parallel-syncs mymaster_26380 4
sentinel deny-scripts-reconfig yes
sentinel resolve-hostnames no
sentinel announce-hostnames no
搭建从的配置 ：
主要的配置：
port 26381
daemonize yes
pidfile "/var/run/redis-sentinel.pid"
logfile "/usr/local/soft/redis-6381/tmp/26381.log"
loglevel debug
dir "/usr/local/soft/redis-6381/tmp"
sentinel monitor mymaster_26380 127.0.0.1 6381 2
默认的配置
acllog-max-len 128
sentinel down-after-milliseconds mymaster_26380 5000
sentinel failover-timeout mymaster_26380 15000
sentinel parallel-syncs mymaster_26380 4
sentinel deny-scripts-reconfig yes
sentinel resolve-hostnames no
sentinel announce-hostnames no
6：启动Redis sentinel
主的，redis-6380 目录下 ./src/redis-sentinel sentinel.conf
从的，redis-6381 目录下 ./src/redis-sentinel sentinel.conf
7：下载配置的Redis截图
8：剩余Redis默认的配置
