文章目录一、下载Redis二、创建Redis管理用户三、上传Redis四、安装Redis五、搭建集群1. 创建集群配置目录redis-cluster/2. 创建master 1节点目录7001复制redis.conf配置文件3. 配置marst 1主节点70014. 配置slave 1从节点70025. 配置剩余集群节点6. 启动集群所有节点7. 创建集群8. 验证集群9. 查看集群信息10. 关闭集群11. 删除节点12. 查看客户端连接情况一、下载Redis官方链接https://redis.io/downloads/这里我选择下载了市场使用比较广泛成熟的6.2版本最新的6.2.14。二、创建Redis管理用户创建redisadm用户作为Redis的运维用户。$mkdir-p/home/redisadm $groupadd-g60010redisgrp $useraddredisadm-u60010-d/home/redisadm-gredisgrp $chown-Rredisadm:redisgrp /home/redisadm $echoredisadm:redisadm|chpasswd三、上传Redis将Redis安装包上传到linux服务器并解压可以通过FTP工具连接上传这里我上传到了/home/redisadm目录下进行安装。使用root用户进行解压缩执行命令$cd/home/redisadm $tar-zxvfredis-6.2.14.tar.gz四、安装Redis注意使用root用户安装。进入刚才的Redis解压缩路径操作我这边是/home/redisadm/redis-6.2.14进行编译执行命令$make安装环境检查执行命令:注意这一步不能报错如果报错了需要检查确实什么插件将插件安装好。$maketest安装执行命令$makeinstall安装成功后我们可以看到Redis相关命令已经加到/usr/local/bin目录下了。五、搭建集群本次我们搭建的Redis集群设计为3台服务器包含3主3从共6个Redis节点每个服务器包含1主1从2个Redis节点分别为master 1、slave1master 2、slave 2master 3、slave 3。集群架构如下图接下来的集群配置时我们可以切换成redisadm用户操作了。1. 创建集群配置目录redis-cluster/$cd/home/redisadm $mkdir-p/home/redisadm/redis-cluster $ ll2. 创建master 1节点目录7001复制redis.conf配置文件$cd/home/redisadm/redis-cluster $mkdir7001$ ll $cp../redis-6.2.14/redis.conf /home/redisadm/redis-cluster/7001/redis.conf $cd7001$ ll3. 配置marst

$mkdir7002$ ll $cp./7001/redis.conf ./7002/redis.conf $cd7002$ ll修改7002目录下redis.conf配置文件将文件内7001替换为7002主要涉及以下参数port 7002 logfile /home/redisadm/redis-cluster/7001/redis.log pidfile /home/redisadm/redis-cluster/7001/redis_7001.pid dir /home/redisadm/redis-cluster/7001/ cluster-config-file nodes-7001.conf5. 配置剩余集群节点配置方法与7002一致替换文件内端口信息。配置文件复制因为我这些是在同一个机器上所以只需要使用cp命令复制到对应的节点文件夹内修改配置文件就行。$cp/home/redisadm/redis-cluster/7001/redis.conf /home/redisadm/redis-cluster/7003/redis.conf $cp/home/redisadm/redis-cluster/7001/redis.conf /home/redisadm/redis-cluster/7004/redis.conf $cp/home/redisadm/redis-cluster/7001/redis.conf /home/redisadm/redis-cluster/7005/redis.conf $cp/home/redisadm/redis-cluster/7001/redis.conf /home/redisadm/redis-cluster/7006/redis.conf但是如果有多台机器的时候就需要使用scp拷贝过去了$scp/home/redisadm/redis-cluster/7001/redis.conf redisadmxxx.xxx.xxx.xxx:/home/redisadm/redis-cluster/7003/redis.conf $scp/home/redisadm/redis-cluster/7001/redis.conf redisadmxxx.xxx.xxx.xxx:/home/redisadm/redis-cluster/7004/redis.conf $scp/home/redisadm/redis-cluster/7001/redis.conf redisadmxxx.xxx.xxx.xxx:/home/redisadm/redis-cluster/7005/redis.conf $scp/home/redisadm/redis-cluster/7001/redis.conf redisadmxxx.xxx.xxx.xxx:/home/redisadm/redis-cluster/7006/redis.conf创建AOF持久化路径因为是在不同服务器上所以我们要自己手动创建集群内其他节点的AOF持久化文件目录。比如在服务器1上有2个节点master 1 7001 slave 17002那我们就创建其余集群节点点目录$mkdir-p/home/redisadm/redis-cluster/7003/ $mkdir-p/home/redisadm/redis-cluster/7004/ $mkdir-p/home/redisadm/redis-cluster/7005/ $mkdir-p/home/redisadm/redis-cluster/7006/6. 启动集群所有节点执行启动命令注意使用redisadm用户启动不然后面创建集群会报错。$cd/home/redisadm/redis-6.2.14/src $ redis-server /home/redisadm/redis-cluster/7001/redis.conf $ redis-server /home/redisadm/redis-cluster/7002/redis.conf $ redis-server /home/redisadm/redis-cluster/7003/redis.conf $ redis-server /home/redisadm/redis-cluster/7004/redis.conf $ redis-server /home/redisadm/redis-cluster/7005/redis.conf $ redis-server /home/redisadm/redis-cluster/7006/redis.conf检查启动是否成功可以看到全部端口启动好并且后面是[cluster]$ps-ef|grepredisadm7. 创建集群创建集群使用create创建cluster-replicas指定从节点个数前3个节点为master后3个为则从节点。需要加上redis.conf内设置的密码redisadm不然会报错。$ /home/redisadm/redis-6.2.14/src/redis-cli--clustercreate --cluster-replicas1127.0.0.1:7001127.0.0.1:7003127.0.0.1:7005127.0.0.1:7002127.0.0.1:7004127.0.0.1:7006-aredisadm8. 验证集群连接任意一个节点测试这里使用7001端口试试。$ /home/redisadm/redis-6.2.14/src/redis-cli-c-h127.0.0.1-p7001-aredisadm去7001端口对应的从节点查询自动跳转到了7001主节点$ /home/redisadm/redis-6.2.14/src/redis-cli-c-h127.0.0.1-p7002-aredisadm换一个主节点7003查询自动跳转到了7001主节点$ /home/redisadm/redis-6.2.14/src/redis-cli-c-h127.0.0.1-p7003-aredisadm9. 查看集群信息查看集群信息:$
