Redis 集群搭建

##### 定义 181,182,183为主 184,185,186为从

##### 所有机器创建数据目录
mkdir /usr/local/redis3/cluster/6379

cd /usr/local/redis3/cluster/6379
vim redis.conf
##### 主上配置文件
port 6379
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes

##### 从上配置文件
port 6379
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes
slave-read-only yes

###### 启动redis,必须切到此目录，数据文件也在此目录产生
cd /usr/local/redis3/cluster/6379
redis-server redis,conf
