安装环境
序号 项目 值
1 OS版本 Red Hat Enterprise Linux Server release 7.1 (Maipo)
2 内核版本 3.10.0-229.el7.x86_64
3 Redis redis-5.0.4
4 Ruby ruby 2.3.4p301 (2017-03-30 revision 58214) [x86_64-linux]
节点信息规划
本来只准备部署7001-7006 6个实例，但是redis集群提示最少需要3个主节点，6个节点才能完成启动，所以后面2个是后来加的。
注意：这里因为是测试环境，所以将所有实例都放在了一台机器上，生产建议主备节点不要放在一台机器上
序号 IP地址 端口 主备 节点配置文件
1 192.168.9.216 7001 主 /data/program/redis/etc/redis-7001.conf
2 192.168.9.216 7002 主 /data/program/redis/etc/redis-7002.conf
3 192.168.9.216 7003 主 /data/program/redis/etc/redis-7003.conf

6 192.168.9.216 7006 备 /data/program/redis/etc/redis-7006.conf
一、下载对应的redis 安装包，并且解压和安装
[root@elk01 opt]# wget http://download.redis.io/releases/redis-5.0.4.tar.gz
--2017-10-26 09:33:23-- http://download.redis.io/releases/redis-5.0.4.tar.gz

-rw-r--r-- 1 root root 1711660 Jul 24 21:59 redis-5.0.4.tar.gz
[root@CentOS program]# mv redis-5.0.4 redis
二、创建对应的需要目录；
[root@elk01 program]# cd redis
[suven@CentOS redis]$ ll
total 268

drwxrwxr-x. 8 suven suven 4096 Mar 18 12:21 utils
三、创建目录脚本如下：
[root@CentOS redis]# mkdir -p /data/program/redis/etc
[root@CentOS redis]# mkdir -p /data/program/redis/logs
[root@CentOS redis]# mkdir -p /data/program/redis/run
[root@CentOS redis]# mkdir -p /data/program/redis/data
[root@CentOS redis]# mkdir -p /data/program/redis/data/{7001,7002,7003,7004,7005,7006}
四、上传配置文件到创建的etc目录上，执行修改脚本：
（1）.修改配置ip:将配置文件大写的IP,转换成对应的服务器ip地址（127.0.0.1），具体到把个配置文件
sed -i "s/IP/ 127.0.0.1" /data/program/redis/etc/redis-7001.conf
或（linux 正规匹配所有文件）
sed -i "s/IP/ 127.0.0.1" /data/program/redis/etc/redis-700*.conf
(2).修改配置文件PORT：将配置文件大写的PORT,转换成对应的redis启动服务端口7001，具体到把个配置文件
sed -i "s/PORT/ 7001" /data/program/redis/etc/redis-7001.conf
sed -i "s/PORT/ 7002" /data/program/redis/etc/redis-7002.conf
sed -i "s/PORT/ 7003" /data/program/redis/etc/redis-7003.conf
sed -i "s/PORT/ 7004" /data/program/redis/etc/redis-7004.conf
sed -i "s/PORT/ 7005" /data/program/redis/etc/redis-7005.conf
sed -i "s/PORT/ 7006" /data/program/redis/etc/redis-7006.conf
执行编译安装命令： make test
[root@localhost redis]# make test
cd src && make test
make[1]: Entering directory `/data/program/redis/src
最后看到的结果：
Hint: It's a good idea to run 'make test' ;)
INSTALL install
INSTALL install
INSTALL install
INSTALL install
INSTALL install
make[1]: Leaving directory `/data/program/redis/src'
备注:分分钟搞定Redis编译安装
1. 依赖包安装
yum -y install cpp binutils glibc glibc-kernheaders glibc-common glibc-devel gcc make gcc-c++ libstdc++-devel tcl
五、启动redis结点服务命令：
[root@CentOS redis] cd /data/program/redis/
[root@CentOS redis] src/redis-server etc/redis-7001.conf
[root@CentOS redis] src/redis-server etc/redis-7002.conf
[root@CentOS redis] src/redis-server etc/redis-7003.conf
[root@CentOS redis] src/redis-server etc/redis-7004.conf
[root@CentOS redis] src/redis-server etc/redis-7005.conf
[root@CentOS redis] src/redis-server etc/redis-7006.conf
六、查看redis结点服务是否正常启动：
[suven@CentOS etc]$ ps -ef | grep redis
root 7470 1 0 00:01 ? 00:00:14 /data/program/redis/src/redis-server 10.211.55.5:7001 [cluster]
root 8377 1 0 00:01 ? 00:00:14 /data/program/redis/src/redis-server 10.211.55.5:7002 [cluster]
root 8591 1 0 00:01 ? 00:00:14 /data/program/redis/src/redis-server 10.211.55.5:7003 [cluster]
root 9597 1 0 00:02 ? 00:00:14 /data/program/redis/src/redis-server 10.211.55.5:7004 [cluster]
root 9816 1 0 00:02 ? 00:00:14 /data/program/redis/src/redis-server 10.211.55.5:7005 [cluster]
root 10031 1 0 00:02 ? 00:00:14 /data/program/redis/src/redis-server 10.211.55.5:7006 [cluster]
suven 19158 9380 0 04:04 pts/0 00:00:00 grep --color=auto redis
注：如果没有看到进程信息；请查看
[root@CentOS redis]$ tail -200f logs/redis7001.log
910:C 25 Mar 2019 23:59:35.959 # Can't chdir to '/data/program/redis/data/7001': No such file or directory

7470:M 26 Mar 2019 00:01:32.456 # Server initialized
七、执行结点实现聚群脚本：
[root@CentOS redis] src/redis-trib.rb create --replicas 1 10.211.55.5:7001 10.211.55.5:7002 10.211.55.5:7003 10.211.55.5:7004 10.211.55.5:7005 10.211.55.5:7006
src/redis-cli --cluster create 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006 --cluster-replicas 1
（1）.注： 需要安装ruby2.2.2以上版本，卸载老版本ruby2.0.0
[root@elk01 ~]# ruby -v
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
[root@elk01 ~]# rpm -qa | grep ruby
ruby-libs-2.0.0.648-29.el7.x86_64
rubygem-bigdecimal-1.2.0-29.el7.x86_64
rubygems-2.0.14.1-29.el7.noarch
rubygem-psych-2.0.0-29.el7.x86_64
rubygem-json-1.7.7-29.el7.x86_64
ruby-irb-2.0.0.648-29.el7.noarch
rubygem-io-console-0.4.2-29.el7.x86_64
ruby-2.0.0.648-29.el7.x86_64
rubygem-rdoc-4.0.0-29.el7.noarch
[root@elk01 ~]# yum erase ruby
注：如果还是旧片本，请参与centos7 rhel7安装较高版本ruby2.2、2.3、2.4笔记执行
（2）.查看ruby软件版本号，如果低于ruby2.2，执行面删除
ruby -v
rpm -qa | grep ruby
（3）.重新安装ruby2.4版本脚本
yum install -y gcc* openssl* wget
yum install centos-release-scl-rh
yum install rh-ruby24 -y
scl enable rh-ruby24 bash
（4）.查看ruby软件版本号
[root@localhost redis]# ruby -v
ruby 2.4.5p335 (2018-10-18 revision 65137) [x86_64-linux]
[root@localhost redis]# yum install rubygems
[root@localhost redis]# gem install redis
八、执行redis 结点聚群脚本；结果如下：其中会提示输入（yes/no）,输入yes 即可；
[root@CentOS redis]# redis-cli --cluster create 10.211.55.5:7001 10.211.55.5:7002 10.211.55.5:7003 10.211.55.5:7004 10.211.55.5:7005 10.211.55.5:7006 --cluster-replicas 1

九、连接到对应的redis 聚群脚本： 一定要 -c
[root@CentOS redis]# src/redis-cli -c -h 10.211.55.5 -p 7001
10.211.55.5:7001>
十、查看redis聚群信息命令：CLUSTER info
10.211.55.5:7001> CLUSTER info
cluster_state:ok
cluster_slots_assigned:16384
cluster_slots_ok:16384

十一、查看redis聚群结点分配信息命令（CLUSTER 区分大小写 ）：CLUSTER nodes
10.211.55.5:7001> CLUSTER nodes

十二、验证是否可用，测试用例
10.211.55.5:7001> set keytest testvalue
OK
10.211.55.5:7001> get keytest
"testvalue"
