两个节点

192.168.1.177 节点一

192.168.1.180 节点二

系统版本：

centos7

资源下载：

下载

http://download.redis.io/releases/redis-4.0.11.tar.gz

https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.3.tar.gz

https://rubygems.org/rubygems/rubygems-2.7.7.tgz

https://rubygems.org/downloads/redis-4.0.1.gem

1、两节点解压，编译安装

\# tar -zxf redis-4.0.11.tar.gz

\# cd redis-4.0.11/

\# make

Hint: It's a good idea to run 'make test' ;)

\# cd src

测试编译报错

\# make test

CC Makefile.dep

You need tcl 8.5 or newer in order to run the Redis test

make: \*\*\* \[test\] Error 1

缺少依赖，进行安装

\# yum install tcl

再次测试编译ok

\# make test

\\o/ All tests passed without errors!

Cleanup: may take some time... OK

安装

\# make PREFIX=/usr/local/redis-4.0.11 install

Hint: It's a good idea to run 'make test' ;)

INSTALL install

配置环境变量

\# vi /etc/profile

export PATH=/usr/local/edis-4.0.11/bin:$PATH

\# source /etc/profile

2、配置节点创建

节点一创建配置节点

\# mkdir -p /usr/local/redis-4.0.11/cluster/7000

\# mkdir /usr/local/redis-4.0.11/cluster/7001

\# mkdir /usr/local/redis-4.0.11/cluster/7002

\# cp /data/opt/redis-4.0.11/redis.conf /usr/local/redis-4.0.11/cluster/7000

\# cp /data/opt/redis-4.0.11/redis.conf /usr/local/redis-4.0.11/cluster/7001

\# cp /data/opt/redis-4.0.11/redis.conf /usr/local/redis-4.0.11/cluster/7002

节点二创建配置节点

\# mkdir -p /usr/local/redis-4.0.11/cluster/7003

\# mkdir /usr/local/redis-4.0.11/cluster/7004

\# mkdir /usr/local/redis-4.0.11/cluster/7005

\# cp /data/opt/redis-4.0.11/redis.conf /usr/local/redis-4.0.11/cluster/7003

\# cp /data/opt/redis-4.0.11/redis.conf /usr/local/redis-4.0.11/cluster/7004

\# cp /data/opt/redis-4.0.11/redis.conf /usr/local/redis-4.0.11/cluster/7005

3、修改配置文件

节点一修改配置文件

\# vi /usr/local/redis-4.0.11/cluster/7000/redis.conf

port 6379

port 7000

bind 127.0.0.1

bind 192.168.1.177

daemonize no

daemonize yes

pidfile /var/run/redis\_6379.pid

pidfile /var/run/redis\_7000.pid

\# cluster-enabled yes

cluster-enabled yes

\# cluster-config-file nodes-6379.conf

cluster-config-file nodes-7000.conf

\# cluster-node-timeout 15000

cluster-node-timeout 15000

appendonly no

appendonly yes

拷贝配置文件

\# cp /usr/local/redis-4.0.11/cluster/7000/redis.conf /usr/local/redis-4.0.11/cluster/7001/redis.conf

\# cp /usr/local/redis-4.0.11/cluster/7000/redis.conf /usr/local/redis-4.0.11/cluster/7002/redis.conf

\# scp /usr/local/redis-4.0.11/cluster/7000/redis.conf root@192.168.1.180:/usr/local/redis-4.0.11/cluster/7003/redis.conf

\# scp /usr/local/redis-4.0.11/cluster/7000/redis.conf root@192.168.1.180:/usr/local/redis-4.0.11/cluster/7004/redis.conf

\# scp /usr/local/redis-4.0.11/cluster/7000/redis.conf root@192.168.1.180:/usr/local/redis-4.0.11/cluster/7005/redis.conf

把带有端口号的配置按照实际情况做修改

4、两节点拷贝src目录下的redis-trib.rb到安装目录下

\# scp /data/opt/redis-4.0.11/src/redis-trib.rb /usr/local/redis-4.0.11/bin

当然也可以编译一台上的redis，之后拷贝到另一台上，然后做修改配置文件及目录即可。

5、两节点编译安装ruby

使用yum安装的话，版本的2.0，不符合要求，所以源码编译更高的版本

上传ruby源码包编译安装

检查下面包有没有安装，没有的话安装，不然编译会报错

zlib

zlib-devel

openssl

openssl-devel

readline

readline-devel

\# tar -zxf ruby-2.5.3.tar.gz

\# cd ruby-2.5.3/

\# ./configure --prefix=/usr/local/ruby

\# make

\# make install

修改配置文件

\# vi /etc/profile

export PATH=/usr/local/ruby/bin:/usr/local/edis-4.0.11/bin:$PATH

\# source /etc/profile

\# ruby -v

ruby 2.5.3p105 (2018-10-18 revision 65156) \[x86\_64-linux

6、启动服务

节点一启动服务

\# cd /usr/local/redis-4.0.11/bin

\# ./redis-server /usr/local/redis-4.0.11/cluster/7000/redis.conf

\# ./redis-server /usr/local/redis-4.0.11/cluster/7001/redis.conf

\# ./redis-server /usr/local/redis-4.0.11/cluster/7002/redis.conf

节点二启动服务

\# cd /usr/local/redis-4.0.11/bin

\# ./redis-server /usr/local/redis-4.0.11/cluster/7003/redis.conf

\# ./redis-server /usr/local/redis-4.0.11/cluster/7004/redis.conf

\# ./redis-server /usr/local/redis-4.0.11/cluster/7005/redis.conf

7、两节点安装gen

如果缺少gen工具的话在创建集群的时候就会报下面的错误

\# ./redis-trib.rb create --replicas 1 192.168.1.177:7000 192.168.1.177:7001 192.168.1.177:7002 192.168.1.180:7003 192.168.1.180:7004 192.168.1.180:7005

Traceback (most recent call last):

2: from ./redis-trib.rb:25:in \`<main>'

1: from /usr/local/ruby/lib/ruby/2.5.0/rubygems/core\_ext/kernel\_require.rb:59:in \`require'

/usr/local/ruby/lib/ruby/2.5.0/rubygems/core\_ext/kernel\_require.rb:59:in \`require': cannot load such file -- redis (LoadError)

\# tar -zxf rubygems-2.7.7.tgz

\# cd rubygems-2.7.7

\# ruby setup.rb

RubyGems installed the following executables:

/usr/local/ruby/bin/gem

/usr/local/ruby/bin/bundle

\# gem install redis-4.0.1.gem

8、创建集群

\# ./redis-trib.rb create --replicas 1 192.168.1.177:7000 192.168.1.177:7001 192.168.1.177:7002 192.168.1.180:7003 192.168.1.180:7004 192.168.1.180:7005
