三台服务器：先设置hosts 10.0.0.231 node1 10.0.0.232 node2 10.0.0.233 node3
端口分配： node1:7000 node1:7001 node2:7002 node2:7003 node3:7004 node3:7005
1：下载redis-4.0.1并解压
解压目录：/usr/local/redis-4.0.1 建立软连接：ln -s redis-4.0.1 redis
2：编译安装
指定安装目录到:/usr/local/redis make && make install PREFIX=/usr/local/redis
3：创建配制节点
node1服务器: mkdir -p /usr/loca/redis/redis_cluster/7000 mkdir -p /usr/loca/redis/redis_cluster/7001 cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7000 cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7001 node2服务器: mkdir -p /usr/loca/redis/redis_cluster/7002 mkdir -p /usr/loca/redis/redis_cluster/7003 cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7002 cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7003 node3服务器: mkdir -p /usr/loca/redis/redis_cluster/7004 mkdir -p /usr/loca/redis/redis_cluster/7005 cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7004 cp /usr/local/redis/redis.conf /usr/loca/redis/redis_cluster/7005
4：修改redis.conf
切记：不能设置密码，否则集群启动时会连接不上 port 7000 //端口根据对应的文件夹去配制端口 7000,7001,7002,7003,7004,7005 bind 本机ip //根据本机所在的IP或hostname去配制 node1 node2 node3 daemonize yes //redis后台运行 pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7001,7002,7003,7004,7005 cluster-enabled yes //开启集群 把注释#去掉 cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7000,7001,7002,7003,7004,7005 cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置 appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志
5：复制src目录中的redis-trib.rb 到/usr/local/redis/bin目录
cp /usr/local/redis/redis-trib.rb /usr/local/redis/bin
6：安装ruby环境
yum install -y ruby yum install -y rubygems
7：安装ruby的包
gem install redis-4.0.0.rc1.gem 如果不成功需要去下载后安装 下载地址 https://rubygems.org/gems/redis/versions/4.0.0.rc1 https://rubygems.org/downloads/redis-4.0.0.rc1.gem 安装命令：gem install -l ./redis-4.0.0.rc1.gem
8：启动各个节点
node1服务器: /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7000/redis.conf /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7001/redis.conf node2服务器: /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7002/redis.conf /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7003/redis.conf node3服务器: /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7004/redis.conf /usr/local/redis/bin/redis-server /usr/loca/redis/redis_cluster/7005/redis.conf
9：检查各节点是否启动
查看进程 ps -ef | grep redis 查看端口 netstat -tnlp | grep redis
10：创建集群
进入node1的bin目录下,执行以下脚本 ./redis-trib.rb create --replicas 1 node1:7000 node1:7001 node2:7002 node2:7003 node3:7004 node3:7005
11：验证集群
进入每台服务器的redis/src目录,记住参数 -c不可以少 redis-cli -h node1 -p 7000 -c redis-cli -h node2 -p 7002 -c redis-cli -h node3 -p 7004 -c
