[root@localhost redis_cluster]# cp /usr/local/soft/redis-3.2.6/redis.conf /usr/local/soft/redis_cluster/7002

修改配置文件

daemonize yes //redis后台运行

pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7002,7003

port 7000 //端口7000,7002,7003

cluster-enabled yes //开启集群 把注释#去掉

cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7000,7001,7002

cluster-node-timeout 5000 //请求超时 设置5秒够了
appendonly yes
bind 真实ip地址

关闭安全模式

redis-cli -p 7000 CONFIG SET protected-mode no

启动redis

[root@localhost redis_cluster]# redis-server /usr/local/soft/redis_cluster/7000/redis.conf
[root@localhost redis_cluster]# redis-server /usr/local/soft/redis_cluster/7001/redis.conf

创建集群

[root@localhost redis_cluster]# cd /usr/local/soft/redis-3.2.6/src/
[root@localhost src]# ./redis-trib.rb
/usr/bin/env: ruby: No such file or directory

如果没有安装ruby，则安装

[root@localhost src]# yum -y install ruby ruby-devel rubygems rpm-build

安装redis接口

[root@localhost src]# gem install redis

查看ruby是否安装成功
