redis集群搭建

    1. Redis集群的搭建

Redis集群中至少应该有三个节点。要保证集群的高可用,需要每个节点有一个备份机。

Redis集群至少需要6台服务器。

搭建伪分布式。可以使用一台虚拟机运行6个redis实例。需要修改redis的端口号7001-7006

      1. 集群搭建环境

1、使用ruby脚本搭建集群。需要ruby的运行环境。

安装ruby

yum install ruby

yum install rubygems

 

  1. 安装ruby脚本运行使用的包。

[root@localhost ~]# gem install redis-3.0.0.gem

Successfully installed redis-3.0.0

1 gem installed

Installing ri documentation for redis-3.0.0...

Installing RDoc documentation for redis-3.0.0...

[root@localhost ~]#

 

[root@localhost ~]# cd redis-3.0.0/src

[root@localhost src]# ll *.rb

-rwxrwxr-x. 1 root root 48141 Apr  1  2015 redis-trib.rb

 

      1. 搭建步骤

需要6台redis服务器。搭建伪分布式。

需要6个redis实例。

需要运行在不同的端口7001-7006

 

第一步:创建6个redis实例,每个实例运行在不同的端口。需要修改redis.conf配置文件。配置文件中还需要把cluster-enabled yes前的注释去掉。

第二步:启动每个redis实例。

第三步:使用ruby脚本搭建集群。

./redis-trib.rb create --replicas 1 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006

 

创建关闭集群的脚本:

[root@localhost redis-cluster]# vim shutdow-all.sh

redis01/redis-cli -p 7001 shutdown

redis01/redis-cli -p 7002 shutdown

redis01/redis-cli -p 7003 shutdown

redis01/redis-cli -p 7004 shutdown

redis01/redis-cli -p 7005 shutdown

redis01/redis-cli -p 7006 shutdown

[root@localhost redis-cluster]# chmod u+x shutdow-all.sh

 

[root@localhost redis-cluster]# ./redis-trib.rb create --replicas 1 192.168.3.28:7001 192.168.3.28:7002 192.168.3.28:7003 192.168.3.28:7004 192.168.3.28:7005  192.168.3.28:7006

[OK] All nodes agree about slots configuration.

>>> Check for open slots...

>>> Check slots coverage...

[OK] All 16384 slots covered.

[root@localhost redis-cluster]#

 

    1. 集群的使用方法

Redis-cli连接集群。

[root@localhost redis-cluster]# redis01/redis-cli -p 7002 -c

-c:代表连接的是redis集群
