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

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

[[email protected] opt]# wget 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
[[email protected] program]# mv redis-5.0.4 redis

二、创建对应的需要目录;
[[email protected] program]# cd redis
[[email protected] redis]$ ll
total 268

drwxrwxr-x.  8 suven suven  4096 Mar 18 12:21 utils

三、创建目录脚本如下:
[[email protected] redis]# mkdir -p /data/program/redis/etc
[[email protected] redis]# mkdir -p /data/program/redis/logs
[[email protected] redis]# mkdir -p /data/program/redis/run
[[email protected] redis]# mkdir -p /data/program/redis/data
[[email protected] 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
[[email protected] 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:

[[email protected] redis] cd /data/program/redis/
[[email protected] redis] src/redis-server  etc/redis-7001.conf
[[email protected] redis] src/redis-server  etc/redis-7002.conf
[[email protected] redis] src/redis-server  etc/redis-7003.conf
[[email protected] redis] src/redis-server  etc/redis-7004.conf
[[email protected] redis] src/redis-server  etc/redis-7005.conf
[[email protected] redis] src/redis-server  etc/redis-7006.conf

六、查看redis结点服务是否正常启动:
[[email protected] 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
[[email protected] 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:
[[email protected] 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
[[email protected] ~]# ruby -v
ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
[[email protected] ~]# 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
[[email protected] ~]# 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
[[email protected] redis]# ruby -v
ruby 2.4.5p335 (2018-10-18 revision 65137) [x86_64-linux]
[[email protected] redis]# yum install rubygems
[[email protected] 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;
[[email protected] 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
[[email protected] 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
cluster_slots_pfail:0

cluster_stats_messages_ping_received:380
cluster_stats_messages_pong_received:385
cluster_stats_messages_meet_received:5
cluster_stats_messages_received:770

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
e3e9c6e39f9969cc202cd90f045c2acb6b12b427 10.211.55.5:[email protected] slave 63243f121eb2e90ea3da9d6c7931b577c313e1a0 0 1553588727578 6 connected

10.211.55.5:7001> 

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"
10.211.55.5:7001>
