系统环境: Centos7 vmware 
redis版本:redis3.2.5 
redis3.2.5需要高版本的ruby和gem,我这边ruby用的最新版本2.3.3,低版本的ruby创建集群的时候会出错 
安装步骤:

一、所需工具初始化

1、安装开发包

#yum install openssl* openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel

openssl、zlib、gcc在安装ruby和gem的时候需要  2、安装ruby

# wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz
# tar zxvf ruby-2.0.0-p247.tar.gz
# cd ruby-2.0.0-p247
# ./configure 
# make && make install
# ruby -v    

3、安装redis-gem

# wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
# gem install redis-3.2.1.gem    

二、rediscluster构建  1、redis下载安装

# wget http://download.redis.io/releases/redis-3.2.5.tar.gz 
# tar -zxf redis-3.2.5.tar.gz
# cd redis-3.2.5
# make && make install

2、集群配置  创建6个redis.conf文件(cluster最少需要6个节点)

# mkdir conf
# cd conf
# vi redis-6379.conf
# cp redis-6379.conf redis-6380.conf 
# cp redis-6379.conf redis-6381.conf 
# cp redis-6379.conf redis-6382.conf 
# cp redis-6379.conf redis-6383.conf 
# cp redis-6379.conf redis-6384.conf

port 6379
daemonize yes
dir /data/redis/redis-6379
logfile /data/redis/redis-7000/redis-6379.log
pidfile /var/run/redis-6379.pid 
dbfilename dump-6379.rdb  

appendonly yes  
appendfilename "appendonly-6379.aof" 

cluster-enabled yes   
cluster-config-file nodes-6379.conf  
cluster-node-timeout 5000    

protected-mode no#关闭保护模式

说明:protected-mode 功能参考如下链接

http://arui.me/index.php/archives/151/

3、启动服务

# ./src/redis-server conf/redis-6379.conf
# ./src/redis-server conf/redis-6380.conf
# ./src/redis-server conf/redis-6381.conf
# ./src/redis-server conf/redis-6382.conf
# ./src/redis-server conf/redis-6383.conf
# ./src/redis-server conf/redis-6384.conf

4、创建集群  使用第二个(IP)创建,用127.0.0.1创建的jediscluster连接不上;  –replicas 1的意思是每个master有1个slave

# ./src/redis-trib.rb  create --replicas 1 127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384

# ./src/redis-trib.rb  create --replicas 1 172.21.20.25:6379 172.21.20.25:6380 172.21.20.25:6381 172.21.20.25:6382 172.21.20.25:6383 172.21.20.25:6384

 
  5、集群检测

#redis-cli -h 172.21.20.25 -p 6379

三、客户端链接  客户端采用的jediscluster,采用的spring boot  1、maven jar

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version><!--$NO-MVN-MAN-VER$-->
</dependency>

2、bean注入

package com.hive.data.redis.config;

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;

import java.util.HashSet;
import java.util.List;
import java.util.Set;

@Configuration
@EnableConfigurationProperties(RedisSettings.class)
public class JedisClusterConfig {
    @Autowired
    private RedisSettings redisSettings;
    @Bean
    public JedisCluster jedisCluster() {
        Set<HostAndPort> set = new HashSet<HostAndPort>();
        List<String> hostPorts = redisSettings.getNodes();
        if (null != hostPorts && hostPorts.size() > 0) {
            String[] ipPortPair;
            for (String hostPort : hostPorts) {
                ipPortPair = hostPort.split(":");
                set.add(new HostAndPort(ipPortPair[0], Integer.parseInt(ipPortPair[1])));
            }
        }
        return new JedisCluster(set,300000);
    }
    @Bean
    public GenericObjectPoolConfig genericObjectPoolConfig(){
        GenericObjectPoolConfig config=new GenericObjectPoolConfig();
        config.setMaxTotal(500);
        config.setMaxIdle(5);
        config.setMaxWaitMillis(1000*100);
        config.setTestOnBorrow(true);
        return config;
    }
}


package com.hive.data.redis.config;

import org.springframework.boot.context.properties.ConfigurationProperties;

import java.util.List;
@ConfigurationProperties(locations = "classpath:redis.properties",prefix = "redis.cluster")
public class RedisSettings {

    private List<String> nodes;


    public List<String> getNodes() {
        return nodes;
    }

    public void setNodes(List<String> nodes) {
        this.nodes = nodes;
    }
}

redis.properties

redis.cluster.nodes[0] =172.21.20.25:6379
redis.cluster.nodes[1] =172.21.20.25:6380
redis.cluster.nodes[2] =172.21.20.25:6381
redis.cluster.nodes[3] =172.21.20.25:6382
redis.cluster.nodes[4] =172.21.20.25:6383
redis.cluster.nodes[5] =172.21.20.25:6384

四、防火墙关闭

我的虚拟机是centos7的默认防火墙,7以下默认是iptables的。

systemctl stop firewalld.service # 关闭防火墙
systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动

iptables设置方法  重启后永久性生效:  开启:chkconfig iptables on  关闭:chkconfig iptables off  即时生效,重启后失效:  开启:service iptables start

关闭:  service iptables stop  重启:service iptables restart  保存配置:service iptables save  或者/etc/rc.d/init.d/iptables save  设置防火墙开机启动  systemctl enable iptables.service  禁止防火墙在系统启动时启动  /sbin/chkconfig –level 2345 iptables off
