1 安装gcc Redis在linux上的安装首先必须先安装gcc，这个是用来编译redis的源文件的
# yum install gcc -y
2、下载解压redis的源文件 https://redis.io/download
# cd /root #wget http://download.redis.io/releases/redis-4.0.2.tar.gz
# tar zxvf redis-4.0.2.tar.gz
3 使用make命令编译
#cd redis-4.0.2/ #make 出现一大堆内容 Hint: It‘s a good idea to run ‘make test‘ ;)提示成功 如果提示错误输入
#make MALLOC=libc
#cd src （src在redis-4.0.2目录下）
#make test 提示You need tcl 8.5 or newer in order to run the Redis test make: *** [test] Error 1 在这里发现有错误 需要安装tcl
4安装TCL并再次测试 tcl（Tool Command Language）工具脚本语言，是Linux内的一种语言包
#yum install tcl -y
#make test 再次测试 这里反正检查的一大堆，最后出现 \o/ All tests passed without errors! 就ok
5安装 到/usr/local/redis
[root@localhost src]# make PREFIX=/usr/local/redis install Hint: It‘s a good idea to run ‘make test‘ ;) INSTALL install INSTALL install INSTALL install INSTALL install INSTALL install 安装成功 [root@localhost redis-4.0.7]# cd /usr/local/redis/bin [root@localhost bin]# ll redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel -> redis-server redis-server 这些都是一个个的命令
6：创建配制节点
服务器1: mkdir -p /usr/local/redis/redis_cluster/7000 mkdir -p /usr/local/redis/redis_cluster/7001 mkdir -p /usr/local/redis/redis_cluster/7002 cp /root/redis-4.0.2/redis.conf /usr/local/redis/redis_cluster/7000 cp /root/redis-4.0.2/redis.conf /usr/local/redis/redis_cluster/7001 cp /root/redis-4.0.2/redis.conf /usr/local/redis/redis_cluster/7002 服务器2: mkdir -p /usr/local/redis/redis_cluster/7003 mkdir -p /usr/local/redis/redis_cluster/7004 mkdir -p /usr/local/redis/redis_cluster/7005 cp /root/redis-4.0.2/redis.conf /usr/local/redis/redis_cluster/7003 cp /root/redis-4.0.2/redis.conf /usr/local/redis/redis_cluster/7004 cp /root/redis-4.0.2/redis.conf /usr/local/redis/redis_cluster/7005
7：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 7001 7002 7003 7004 7005 //端口根据对应的文件夹去配制端口 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
8：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
9.1 redis-trib.rb环境准备（该文件存在于redis-4.0.2/src/目录中） //只需要在其中一台上执行此步骤！！
redis-trib.rb是采用Ruby实现的Redis集群管理工具。内部通过Cluster相关命令帮助 我们简化集群创建、检查、槽迁移和均衡等常见操作，使用之前需要安装Ruby依赖环境。 centos7/rhel7安装较高版本ruby2.2/2.3/2.4+ 我的yum时网易的，用yum安装ruby的版本为2.0.0 在创建集群的时候提示需要高于2.2.2的版本 所以不能用yum安装 建议采用方法二 更换yum源
：换yum源安装 ~]# yum install centos-release-scl-rh //会在/etc/yum.repos.d/目录下多出一个CentOS-SCLo-scl-rh.repo源 ~]# yum install rh-ruby23 -y //直接yum安装即可 软件集合的软件包安装在/opt目录下， 要使用它，需要加载环境变量，如下所示: ~]# scl enable rh-ruby23 bash //必要一步 ~]# ruby -v //查看安装版本 续：接上文提到的报错问题：“redis requires Ruby version >= 2.2.2” ~]# gem install redis 然后，redis-trib.rb这个二进制文件就可以使用了，用来构建redis集群
9.2 这样安装后每次重启或者重新连接crt时发现 不能输入ruby -v 等命令 自然也就无法输入./redis-trib.rb check 172.16.1.23:7002 这些检测命令，需要设置登录时自动启用Ruby 2.3，按如下所示进行配置
# ruby -v ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux] # which ruby /opt/rh/rh-ruby23/root/usr/bin/ruby //查看软件包安装路径 #cd /etc/profile.d/ #touch rh-ruby23.sh //新建一个文件 #vim rh-ruby23.sh #!/bin/bash source /opt/rh/rh-ruby23/enable export X_SCLS="`scl enable rh-ruby23 ‘echo $X_SCLS‘`" export PATH=$PATH:/opt/rh/rh-ruby23/root/usr/local/bi
10：启动各个节点
1服务器: # cd /usr/local/redis/bin/ ./redis-server /usr/local/redis/redis_cluster/7000/redis.conf ./redis-server /usr/local/redis/redis_cluster/7001/redis.conf ./redis-server /usr/local/redis/redis_cluster/7002/redis.conf 2服务器: # cd /usr/local/redis/bin/ ./redis-server /usr/local/redis/redis_cluster/7003/redis.conf ./redis-server /usr/local/redis/redis_cluster/7004/redis.conf ./redis-server /usr/local/redis/redis_cluster/7005/redis.conf
11：检查各节点是否启动
ps -ef | grep redis 查看进程
netstat -tnlp | grep redis 查看端口
12：创建集群 只在一台上配置即可
进入node1的bin目录下,执行以下脚本 #./redis-trib.rb create --replicas 1 172.16.1.23:7000 172.16.1.23:7001 172.16.1.23:7002 172.16.1.24:7003 172.16.1.24:7004 172.16.1.24:7005
13：验证集群
1 简单命令 # cd /usr/local/redis/bin [root@localhost bin]# ll dump.rdb redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-sentinel -> redis-server redis-server [root@localhost bin]# ./redis-cli 连接客户端 127.0.0.1:6379> ping 检查网络是否可以 PONG 127.0.0.1:6379> set name kobe 设置一个键值对 OK 127.0.0.1:6379> get name "kobe" 127.0.0.1:6379> keys * 查看所有的键 1) "name" 127.0.0.1:6379> del name 删除name这个键 (integer) 1 127.0.0.1:6379> keys * (empty list or set
