redis5.0 Cluster集群搭建

1. 安装redis

   sudo apt update  
   sudo apt install build-essential tcl  
   cd ~  
   mkdir document/   
   cd document/  
   curl -O http://download.redis.io/redis-stable.tar.gz  
   tar zxvf redis-stable.tar.gz  
   cd redis-stable/  
   make  
   make test  
   sudo make install  
   cp ~/document/redis-stable/src/redis-trib.rb /usr/local/bin  
   

2. 开始集群搭建

   1. 修改配置文件

      # 设置配置文件目录  
      sudo mkdir -p /etc/redis/redis-cluster/7000  
      cd /etc/redis/  
      # 创建一份配置文件，Cluster架构-3主3从  
      sudo cp redis.conf redis-cluster/7000/redis.conf  
      # 修改配置文件  
      sudo vim redis-cluster/7000/redis.conf  
      

      配置文件修改如下部分

      daemonize    yes  # redis后台运行  
      pidfile  /var/run/redis_7000.pid  #需要修改为 reids_{port}.pid 的形式  
      port  7000  #端口  
      cluster-enabled  yes #开启集群  
      cluster-config-file  7000/nodes_7000.conf #集群的配置文件 nodes_{port}.conf的形式  
      cluster-node-timeout  5000 #超时时间 5s够了  
      appendonly  yes #开启AOF日志  
      

      将配置文件复制5份，并修改每份文件的端口号

      # 创建5份配置文件路径   
      sudo mkdir -p /etc/redis/redis-cluster/7001  
      sudo mkdir -p /etc/redis/redis-cluster/7002  
      sudo mkdir -p /etc/redis/redis-cluster/7003  
      sudo mkdir -p /etc/redis/redis-cluster/7004  
      sudo mkdir -p /etc/redis/redis-cluster/7005  
      # 复制5份配置文件  
      cd /etc/redis/  
      sudo cp redis-cluster/7000/redis.conf redis-cluster/7001/  
      sudo cp redis-cluster/7000/redis.conf redis-cluster/7002/  
      sudo cp redis-cluster/7000/redis.conf redis-cluster/7003/  
      sudo cp redis-cluster/7000/redis.conf redis-cluster/7004/  
      sudo cp redis-cluster/7000/redis.conf redis-cluster/7005/  
      # 修改端口号  
      sudo sed -i "s/7000/7001/g" /etc/redis/redis-cluster/7001/redis.conf  
      sudo sed -i "s/7000/7002/g" /etc/redis/redis-cluster/7002/redis.conf  
      sudo sed -i "s/7000/7003/g" /etc/redis/redis-cluster/7003/redis.conf  
      sudo sed -i "s/7000/7004/g" /etc/redis/redis-cluster/7004/redis.conf  
      sudo sed -i "s/7000/7005/g" /etc/redis/redis-cluster/7005/redis.conf  
      

   2. 启动Redis

      cd /etc/redis/redis-cluster/  
      sudo redis-server 7000/redis.conf  
      sudo redis-server 7001/redis.conf  
      sudo redis-server 7002/redis.conf  
      sudo redis-server 7003/redis.conf  
      sudo redis-server 7004/redis.conf  
      sudo redis-server 7005/redis.conf  
      

   3. 创建集群

      sudo 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  
      # 等一会 然后输入  
      yes  
      

   4. 检查集群状态

      redis-cli --cluster check 127.0.0.1:7000  #填写任意节点即可 会带出所有的  
      

3. 连接redis集群

   redis-cli -c -h 127.0.0.1 -p 7000  
   127.0.0.1:7000> set hi redis  
   -> Redirected to slot [16140] located at 127.0.0.1:7002  
   OK  
   127.0.0.1:7002> get hi  
   "redis"
