Redis集群部署文档(Centos6.5 minal)


(要让集群正常工作至少需要3个主节点,在这里我们要创建6redis节点,其中三个为主节点,三


个为从节点,对应的redis节点的ip和端口对应关系如下)


127.0.0.1:7000


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



1:下载redis官网下载3.0.4版本,之前2.x几的版本不支持集群模式


下载地址:http://download.redis.io/releases/redis3.0.4.tar.gz


2:上传服务器,解压,编译 tar zxvf redis3.0.4.tar.gz


mv redis3.0.0rc2.tar.gz redis3.0 cd /usr/local/redis3.0

make make install


3:创建集群需要的目录 mkdir p /usr.local/cluster cd /usr.local/cluster mkdir 7000

mkdir 7001 mkdir 7002 mkdir 7003 mkdir 7004 mkdir 7005



4:修改配置文件redis.conf cp /usr/local/redis3.0/redis.conf /usr.local/cluster vi redis.conf ##修改配置文件中的下面选项 port 7000

daemonize yes


clusterenabled yes


clusterconfigfile nodes.conf


clusternodetimeout 5000


appendonly yes


##修改完redis.conf配置文件中的这些配置项之后把这个配置文件分别拷贝


7000/7001/7002/7003/7004/7005目录下面


cp /usr/local/cluster/redis.conf /usr/local/cluster/7000 cp /usr/local/cluster/redis.conf /usr/local/cluster/7001 cp /usr/local/cluster/redis.conf /usr/local/cluster/7002 cp /usr/local/cluster/redis.conf /usr/local/cluster/7003 cp /usr/local/cluster/redis.conf /usr/local/cluster/7004 cp /usr/local/cluster/redis.conf /usr/local/cluster/7005


##注意:拷贝完成之后要修改7001/7002/7003/7004/7005目录下面redis.conf文件中的port参数,分


别改为对应的文件夹的名称




5:分别启动这6redis实例


cd /usr/local/cluster/7000 redisserver redis.conf cd /usr/local/cluster/7001 redisserver redis.conf cd /usr/local/cluster/7002 redisserver redis.conf cd /usr/local/cluster/7003 redisserver redis.conf cd /usr/local/cluster/7004 redisserver redis.conf cd /usr/local/cluster/7005 redisserver redis.conf




##启动之后使用命令查看redis的启动情况ps ef|grep redis


如下图显示则说明启动成功




6:执行redis的创建集群命令创建集群


cd /usr/local/redis3.0/src

./redistrib.rb create


replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1


6.1执行上面的命令的时候会报错,因为是执行的ruby的脚本,需要ruby的环境


错误内容:/usr/bin/env: ruby: No such file or directory


所以需要安装ruby的环境,这里推荐使用yum install ruby安装


yum install ruby




6.2然后再执行第6步的创建集群命令,还会报错,提示缺少rubygems组件,使用yum安装



错误内容:


./redistrib.rb:24:in `require': no such file to load rubygems (LoadError)


from ./redistrib.rb:24


yum install rubygems


6.3再次执行第6步的命令,还会报错,提示不能加载redis,是因为缺少redisruby的接口,使


gem 安装


错误内容:


/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to redis (LoadError)

from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from ./redistrib.rb:25


gem install redis




6.4 再次执行第6步的命令,正常执行
