redis集群搭建

1、redis安装

  wget http://download.redis.io/releases/redis-5.0.0.tar.gz
  tar xzf redis-5.0.0.tar.gz
  cd redis-5.0.0
  make

进入src目录启动redis

  src/redis-server

使用内置客服端与redis交互

   src/redis-cli
   redis>set name redis
   OK
   redis>get name
   "redis"

2、redis集群
创建目录cluster-demo

    cd cluster-demo
    mkdir 7000 7001 7002 7003 7004 7005 

redis集群最小的配置node_7000.conf

     port 7000
     cluster-enabled yes
     cluster-config-file node_7000.conf
     cluster-node-timeout 5000
     appendonly yes

在每个目录中创建一个文件，从7000到7005以node_7000.conf作为配置文件的模板，注意确保7000根据目录名称用正确的端口号替换端口号
3、启动redis服务

  ./redis-5.0.0/src/redis-server ./cluster-demo/7000/node_7000.conf
  ./redis-5.0.0/src/redis-server ./cluster-demo/7001/node_7001.conf
  ./redis-5.0.0/src/redis-server ./cluster-demo/7002/node_7002.conf
  ./redis-5.0.0/src/redis-server ./cluster-demo/7003/node_7003.conf
  ./redis-5.0.0/src/redis-server ./cluster-demo/7004/node_7004.conf
  ./redis-5.0.0/src/redis-server ./cluster-demo/7005/node_7005.conf

4、创建集群

  ./redis-5.0.0/src/redis-cli --cluster create 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 --cluster-replicas 1

5、测试

  src/redis-cli -c -p 7000
  127.0.0.1:7000>set name cluster
  OK
  src/redis-cli -c -p 7000
  127.0.0.1:7001>get name
  "cluster"
