redis多机多节点的集群部署可参考redis单机多节点的部署部分[http://blog.csdn.net/duguxingfeng/article/details/78918333][http_blog.csdn.net_duguxingfeng_article_details_78918333]

这里分别用VMware的两台虚拟机做部署 分别是centos7\_1  192.168.0.164与centos\_2 192.168.0.170

**1.分别在164与170机器上安装redis**

164机器为之前单机多节点部署的机器。

在170上安装redis 参考：[http://blog.csdn.net/duguxingfeng/article/details/78911640][http_blog.csdn.net_duguxingfeng_article_details_78911640]

**2.创建节点，修改配置**

首先我们在192.168.0.164虚拟机里创建三个节点，端口分别是7001，7002，7003

[root@localhost ~]# mkdir redis_cluster
    
    [root@localhost ~]#  cd redis_cluster/
    
    [root@localhost redis_cluster]# mkdir 7001 7002 7003

同理我们在192.168.0.170虚拟机里创建三个节点，端口分别是7004，7005，7006

分别修改7001-7006下的配置文件

[root@localhost ~] vi redis_cluster/7001/redis.conf

**a. 192.168.0.164的机器 修改一下几个属性**

port 7001  //三个节点配置文件分别是7001-7003

bind 192.168.0.164   #默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访，和单机集群有区别
    
    daemonize yes        #redis后台运行
    
    pidfile /var/run/redis_7001.pid   #pidfile文件对应7001-7003
    
    cluster-enabled yes   #开启集群
    
    cluster-config-file nodes_7001.conf  #保存节点配置，自动创建，自动更新对应7001-7003
    
    cluster-node-timeout 5000    #集群超时时间，节点超过这个时间没反应就断定是宕机

**b.同理192.168.0.170的机器 修改一下几个属性**

bind 192.168.0.170   #默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访，和单机集群有区别
    
    daemonize yes        #redis后台运行
    
    pidfile /var/run/redis_7004.pid   #pidfile文件对应7004-7006
    
    cluster-enabled yes   #开启集群
    
    cluster-config-file nodes_7001.conf  #保存节点配置，自动创建，自动更新对应7004-7006
    
    cluster-node-timeout 5000    #集群超时时间，节点超过这个时间没反应就断定是宕机

**3.分别启动164与170机器上的节点**

**164机器：**

[root@localhost ~]# /usr/local/redis/bin/redis-server redis_cluster/7001/redis.conf 
    
    [root@localhost ~]# /usr/local/redis/bin/redis-server redis_cluster/7002/redis.conf 
    
    [root@localhost ~]# /usr/local/redis/bin/redis-server redis_cluster/7003/redis.conf

170机器：

[root@localhost ~]# /usr/local/redis/bin/redis-server redis_cluster/7004/redis.conf 
    
    [root@localhost ~]# /usr/local/redis/bin/redis-server redis_cluster/7005/redis.conf 
    
    [root@localhost ~]# /usr/local/redis/bin/redis-server redis_cluster/7006/redis.conf

**4.分别关闭两台机器的防火墙**

[root@localhost ~]# systemctl stop firewalld.service
    [root@localhost ~]# systemctl disable firewalld.service

`5.创建集群 在164机器上（因为之前部署过redis单机多节点，顾可省略安装ruby，以及redis和ruby连接）`

yum -y install ruby ruby-devel rubygems rpm-build

gem install redis

在164上创建集群

[root@localhost ~]# redis-trib.rb create --replicas 1 192.168.0.164:7001 192.168.0.164:7002 192.168.0.164:7003 192.168.0.170:7004 192.168.0.170:7005 192.168.0.170:7006

Can I set the above configuration? (type 'yes' to accept):
