目标（本文达成的结果，配对关系可能会变）：
先在131上进行操作
1.下载redis
http://download.redis.io/releases/redis-5.0.2.tar.gz
2.解压
[testapp@k8s-node2 ~]$ mkdir redis
[testapp@k8s-node2 ~]$ cd redis
上传文件
[testapp@k8s-node2 ~/redis]$ tar -zxvf redis-5.0.2.tar.gz
3.修改/usr/local/bin/权限
su - root
chmod 777 /usr/local/bin/
su - testapap
建立文件夹
[testapp@k8s-node2 ~/redis]$ mkdir redis_cluster [testapp@k8s-node2 ~/redis]$ mkdir logs [testapp@k8s-node2 ~/redis]$ touch logs/redis_run.logs [testapp@k8s-node2 ~/redis]$ cp /redis-5.0.2/redis.conf . [testapp@k8s-node1 ~/redis]$ ll 总用量 1908 drwxrwxr-x 2 testapp testapp 77 8月 14 17:00 logs drwxrwxr-x 6 testapp testapp 309 11月 22 2018 redis-5.0.2 -rw-rw-r-- 1 testapp testapp 1952989 8月 14 15:33 redis-5.0.2.tar.gz drwxrwxr-x 2 testapp testapp 268 8月 14 18:56 redis_cluster
[testapp@k8s-node1 ~/redis]$ pwd
/home/ap/testapp/redis
4.修改配置文件
port 6380 //端口（从节点使用6381端口）
#bind 127.0.0.1 //需要注释掉该配置
daemonize yes //redis后台运行
logfile “/home/ap/testapp/redis/logs/redis_run.log”//配置redis日志路径
pidfile /home/ap/testapp/redis/redis_cluster/redis_6380.pid //redis的进程文件
appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志
dir /home/ap/testapp/redis/redis_cluster/ //数据库备份的文件放置的路径
Protected-mode no //是否开启保护模式
cluster-enabled yes //开启集群 把注释#去掉
cluster-config-file /home/ap/testappl/redis/redis_cluster/nodes_6380.conf //集群的配置
cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置
5.安装
cd redis-5.0.2
make && make install
6.启动
/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis.conf
ps -ef | grep redis
7.关闭防墙
systemctl status firewalld //查看防火墙状态
systemctl is-enabled firewalld //查看开机是否启动防火墙服务
systemctl stop firewalld //关闭防火墙
systemctl disable firewalld //禁用防火墙（系统启动时不启动防火墙服务）
8.组成集群
关闭6380
/home/ap/testapp/software/redis/redis-5.0.2/src/redis-cli -c -p 6380 shutdown
配置集群conf
cp redis.conf redis6380.conf
cp redis.conf redis6381.conf ##并更改内容中6380 为6381
cp redis.conf redis6382.conf ##并更改内容中6380 为6382
rm redis.conf
依次启动6380 6381 6382
/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis6380.conf
/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis6381.conf
/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis6382.conf
再在192.168.111.132重复1--8
组成集群

修改每个redis638*.conf
masterauth <master-password> 改为 masterauth test@123
requirepass foobared 改为 requirepass test@123
一向比较懒的我

9.1集群相关信息查看
9.1.1集群状态
redis-cli -h ip -p 9379 -a password cluster info
9.1.2.集群节点信息
redis-cli -h ip -p 9379 -a password cluster nodes
9.1.3.节点内存、cpu、key数量等信息（每个节点都需查看）
redis-cli -h ip -p 9379 -a password info
9.1.4.从redis集群中查看key（只需要连接master节点查看）
a.查看该节点的所有key
