Redis集群部署安装

Linux版本：CentOS release 6.9

Redis 版本：redis-3.2.12.tar.gz

1、执行解压命令

tar -xzf redis-3.2.12.tar.gz

2、执行编译命令

make MALLOC=libc

3、执行安装到指定目录命令，此次指定目录为 /my/mysys/redis

make PREFIX=/my/mysys/redis install

完成后目录结构

4、单服务器模拟3主3从部署

3) 启动

/jq_redis/cp001/redis/bin/redis-server /jq_redis/cp001/redis.conf

/jq_redis/cp002/redis/bin/redis-server /jq_redis/cp002/redis.conf

/jq_redis/cp003/redis/bin/redis-server /jq_redis/cp003/redis.conf

/jq_redis/cp004/redis/bin/redis-server /jq_redis/cp004/redis.conf

/jq_redis/cp005/redis/bin/redis-server /jq_redis/cp005/redis.conf

/jq_redis/cp006/redis/bin/redis-server /jq_redis/cp006/redis.conf

4) 配置集群

进入任意一个节点

/jq_redis/cp001/redis/bin/redis-cli -h 192.168.96.128 -p 6371

与其他节点握手

cluster meet 192.168.96.128 6372

cluster meet 192.168.96.128 6373

cluster meet 192.168.96.128 6374

cluster meet 192.168.96.128 6375

cluster meet 192.168.96.128 6376

分配 hash 槽

/jq_redis/cp001/redis/bin/redis-cli -h 192.168.96.128 -p 6371 cluster addslots {0..5461}

/jq_redis/cp002/redis/bin/redis-cli -h 192.168.96.128 -p 6372 cluster addslots {5462..10922}

/jq_redis/cp003/redis/bin/redis-cli -h 192.168.96.128 -p 6373 cluster addslots {10923..16383}

5) 复制节点

登陆节点查看节点信息

cluster nodes

依次登陆3个副本节点，设置复制的节点id

[root@centos01 ~]# /jq_redis/cp001/redis/bin/redis-cli -h 192.168.96.128 -p 6374

192.168.96.128:6374> cluster replicate 1fcec13c4ba9d580cc8a30eab636f52f2c95effb

OK

192.168.96.128:6374> exit

192.168.96.128:6375> cluster replicate a10ea0df49121e7d609520b21b26d012db551923

OK

192.168.96.128:6375> exit

[root@centos01 ~]# /jq_redis/cp001/redis/bin/redis-cli -h 192.168.96.128 -p 6376
