【郑州校区】品优购电商系统部署 Day 1 十四

3.2.3 配置集群
（1）修改每个 redis 节点的配置文件 redis.conf
修改运行端口为 7001 （7002 7003 .....）

将 cluster-enabled yes 前的注释去掉(632 行)


（2）启动每个 redis 实例
以第一个实例为例，命令如下

cd /usr/local/redis-cluster/redis-1/bin/

./redis-server redis.conf


把其余的 5 个也启动起来，然后查看一下是不是都启动起来了

[root@localhost ~]# ps -ef | grep redis

root 15776 15775 0 08:19 pts/1 00:00:00 ./redis-server *:7001 [cluster]

root 15810 15784 0 08:22 pts/2 00:00:00 ./redis-server *:7002 [cluster]

 root 15872 15856 0 08:24 pts/5 00:00:00 ./redis-server *:7005 [cluster]

root 15891 15875 0 08:24 pts/6 00:00:00 ./redis-server *:7006 [cluster]

root 15926 15895 0 08:24 pts/7 00:00:00 grep redis

（3）上传 redis-3.0.0.gem ，安装 ruby 用于搭建 redis 集群的脚本。
