新建redis集群

redis版本

5.0.5

主备规划

三主三从

安装路径

/opt/redis-5.0.5

操作步骤

1. 安装依赖

   # 需要外网
   yum  install -y gcc
   

2. 复制安装包到 /opt/data_collection

   # 使用rz命令将安装包上传
   rz
   

3. 解压安装包到/opt目录

   tar -zxvf redis-5.0.5.tar.gz -C /opt
   

4. 编译

   cd /opt/redis-5.0.5
   make PREFIX=/opt/redis-5.0.5 install
   

5. 复制配置文件到 /opt/redis-5.0.5

   cp redis.conf redis-6379.conf
   

6. 修改生成配置文件

   vi redis-6379.conf
   # 文件内容如下
       #bind 127.0.0.1
       port 6379
       dir /data01/redis/6379
       pidfile /var/run/redis_6379.pid
       daemonize yes
       cluster-enabled yes
       cluster-config-file nodes-6379.conf
       cluster-node-timeout 15000
       appendonly yes
       appendfilename "appendonly.aof"
       protected-mode no
       maxclients 100000
       timeout 3600
   
   # 复制生成 6380配置文件
   
   cp redis-6379.conf redis-6380.conf
   
   # 把上述6379改成6380
   %s/6379/6380/g
   

7. 复制到其他集群机器

   scp redis-6379.conf redis-6380.conf root@datanode01:/opt/redis-5.0.5
   scp redis-6379.conf redis-6380.conf root@datanode02:/opt/redis-5.0.5
   
   # 每台机器都执行
   mkdir -p /data01/redis/6379
   mkdir -p /data01/redis/6380
   

8. 启动redis

   cd /opt/redis-5.0.5
   ./bin/redis-server redis-6379.conf 
   ./bin/redis-server redis-6380.conf 
   

9. 设置集群模式

   ./bin/redis-cli --cluster create 172.168.63.1:6379 172.168.63.1:6380 172.168.63.2:6379 172.168.63.2:6380 172.168.63.3:6379 172.168.63.3:6380 --cluster-replicas 1
   

10. 连接检查

    ./bin/redis-cli -c -h 172.168.63.1  -p 6379 cluster info
    

11. 关闭redis

    ./bin/redis-cli -h localhost -p 6379 shutdown
    ./bin/redis-cli -h localhost -p 6380 shutdown
