本篇内容介绍了“Redis 集群部署方法”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让丸趣 TV 小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

1、主从节点均安装好 redis 以及 ruby。
[root@D2-LZY245 redis-4.0.1]# yum -y install ruby ruby-devel rubygems rpm-build
[root@D2-LZY245 redis-4.0.1]# gem install redis

2、主节点创建集群目录、配置参数并启动
[root@D2-LZY245 ~]# cd redis-4.0.1/
[root@D2-LZY245 redis-4.0.1]# mkdir redis_cluster
[root@D2-LZY245 redis-4.0.1]# cd redis_cluster/
[root@D2-LZY245 redis_cluster]# mkdir 7000 7001 7002
[root@D2-LZY245 redis_cluster]# cp ../redis.conf 7000/
[root@D2-LZY245 redis_cluster]# vim 7000/redis.conf
[root@D2-LZY245 redis_cluster]# egrep ^port|^bind|^daemonize|^pidfile|^cluster-enabled|^cluster-config-file|^cluster-node-timeout|^appendonly 7000/redis_7000.conf

port 7000
daemonize yes
pidfile /var/run/redis_7000.pid
appendonly yes
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 15000
[root@D2-LZY245 redis_cluster]# mv 7000/redis.conf 7000/redis_7000.conf
[root@D2-LZY245 redis_cluster]# cp 7000/redis_7000.conf 7001/redis_7001.conf

4、创建集群
[root@D2-LZY245 redis-4.0.1]# src/redis-trib.rb create –replicas 1 10.163.89.245:7000 10.163.89.245:7001 10.163.89.245:7002 10.163.89.15:7003 10.163.89.15:7004 10.163.89.15:7005

5、测试
在主节点 7000 端口设置 key：
[root@D2-LZY245 ~]# cd redis-4.0.1/
[root@D2-LZY245 redis-4.0.1]# src/redis-cli -h 10.163.89.245 -c -p 7000
10.163.89.245:7000 set key1 hello world
– Redirected to slot [9189] located at 10.163.89.15:7003
OK
10.163.89.15:7003 keys *
1) key1

在从节点 7005 端口查看：
[root@D2-TRAIN15 redis-4.0.1]# src/redis-cli -h 10.163.89.15 -c -p 7005
10.163.89.15:7005 get key1
– Redirected to slot [9189] located at 10.163.89.15:7003
hello world
