redis-cluster集群的搭建

1.搭建三主三从的cluster的集群的搭建

2.配置环境

redis版本要求：redis大版本为5.0.8

安装环境: 

    软件下载地址http://download.redis.io/releases/

    服务器系统---centos6.5

    安装包存放目录 /home/app

    redis安装目录/home/app/redis

    配置文件  /home/app/redis/conf/redis_cluster

    可执行命令  /home/app/redis/bin/*  被链接到  /usr/local/bin/

2.6台机器分别安装redis，并启动redis

3.修改系统参数

echo "* soft nofile 10240" >> /etc/security/limits.conf

echo "* hard nofile 10240" >> /etc/security/limits.conf

echo "net.core.somaxconn = 10240" >> /etc/sysctl.conf

echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf

sysctl -p

echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo never > /sys/kernel/mm/transparent_hugepage/defrag

echo 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' >> /etc/rc.local

echo 'echo never > /sys/kernel/mm/transparent_hugepage/defrag' >> /etc/rc.local

4.添加redis到集群中

redis5以上集群添加命令:

./redis-cli --cluster create 192.168.4.206:9000 192.168.4.214:9000 192.168.4.207:9000 192.168.4.215:9000 192.168.4.208:9000 192.168.4.212:9000 --cluster-replicas 1

redis5以下的命令：

./redis-trib.rb create --replicas 1 192.168.4.206:9000 192.168.4.214:9000 192.168.4.207:9000 192.168.4.215:9000 192.168.4.208:9000 192.168.4.212:9000

5.查看cluster的状态
