一、环境准备

1.  Centos7(离线环境下)
2.  redis安装包redis-5.0.4.tar.gz      下载地址：[https://redis.io/download][https_redis.io_download]
3.  ruby安装包ruby-2.5.5.tar.gz      下载地址：[http://www.ruby-lang.org/en/downloads/][http_www.ruby-lang.org_en_downloads]
4.  zlib安装包zlib-1.2.11.tar.gz      下载地址：[http://www.zlib.net][http_www.zlib.net]
5.  rubygems安装包rubygems-3.0.3.tgz      下载地址： [https://rubygems.org/pages/download][https_rubygems.org_pages_download]
6.  oppenssl安装包openssl-1.0.2n.tar.gz      下载地址：[https://oomake.com/download/openssl][https_oomake.com_download_openssl]
7.  redis依赖库redis-4.1.0.gem      下载地址：[https://rubygems.org/gems/redis/][https_rubygems.org_gems_redis]

将以上安装包都放到CentOS7系统中(基于xshell  xftp上传)，可以自定义路径和文件夹，**此处我将安装包都放在/root/public下面**

二、环境安装

1、redis安装需要依托gcc环境，先检查gcc是否安装，通过版本号查看，如果已经安装gcc会出现如下提示。

[root@localhost ~]# gcc -v
    使用内建 specs。
    COLLECT_GCC=gcc
    COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper
    目标：x86_64-redhat-linux
    配置为：../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto --enable-plugin --enable-initfini-array --disable-libgcj --with-isl=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/isl-install --with-cloog=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/cloog-install --enable-gnu-indirect-function --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux
    线程模型：posix
    gcc 版本 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)

2、**安装ruby。**进入public文件夹，解压ruby安装文件。

[root@localhost public]# tar -zxvf ruby-2.5.5.tar.gz

3、进入解压后的ruby文件夹，将ruby安装到指定目录/usr/local/ruby，编译安装

[root@localhost ruby-2.5.5]# ./configure --prefix=/usr/local/ruby  ##是将ruby安装到指定目录，也可以自定义
    [root@localhost ruby-2.5.5]# make && make install  ##编译安装

4、ruby安装完成后，配置ruby环境变量。编辑vim /etc/profile文件，在文件当中PATH当中加入安装Ruby的bin目录路径。然后保存执行命令：source /etc/profile让配置立即生效，然后echo $PATH可以查看变量已被添加。ruby -v 命令查看是否安装成功。

![20190423181721763.png][]

[root@localhost rubygems-3.0.3]# source /etc/profile  ##配置生效
    [root@localhost ruby-2.5.5]# echo $PATH
    /usr/local/ruby/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/git/bin:/root/bin:/usr/local/git/bin
    
    [root@localhost ruby-2.5.5]# ruby -v   ##查看ruby安装成功
    ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-linux]

5、**zlib安装。**进入public文件夹，解压zlib安装文件，并安装。

[root@localhost public]# tar -zxvf zlib-1.2.11.tar.gz  ##解压
    [root@localhost public]# cd zlib-1.2.11    ##进入解压后的安装包
    [root@localhost zlib-1.2.11]# ./configure --prefix=/usr/local/zlib  ##设置安装路径
    [root@localhost zlib-1.2.11]# make && make install   ##编译安装

6、**安装rubygems-3.0.3**。 进入public文件夹，解压rubygems安装文件，然后执行命令：ruby setup.rb

[root@localhost public]# tar -zxvf rubygems-3.0.3.tgz  ##解压
    [root@localhost public]# cd rubygems-3.0.3  ##进入解压后文件
    [root@localhost rubygems-3.0.3]# ruby setup.rb  ##执行命令

安装成功出现如下信息。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTA0NjM2MTM_size_16_color_FFFFFF_t_70][]

7、rubygems安装完成后，配置rubygems环境变量。编辑vim /etc/profile文件，在文件当中PATH当中加入安装rubygems的bin目录路径，路径为安装目录bin文件夹/root/public/rubygems-3.0.3/bin/ 【这个路径就是你解压出rubygems的路径】 然后保存，执行命令：source /etc/profile让配置立即生效，然后echo $PATH可以查看变量已被添加。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTA0NjM2MTM_size_16_color_FFFFFF_t_70 1][]

8、**redis安装。**进入public文件夹，解压redis并编译安装。

[root@localhost public]# tar -zxvf redis-5.0.4.tar.gz  ##解压
    [root@localhost public]# cd redis-5.0.4   ##进入解压后文件夹
    [root@localhost redis-5.0.4]# make && make install  ##编译安装

9、进入redis安装文件解压后的文件夹下运行redis-server redis.conf命令启动redis，如果启动成功，会出现如下界面。

[root@localhost redis-5.0.4]# redis-server redis.conf   ##启动redis
    48367:C 24 Apr 2019 18:51:47.462 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

Redis must be restarted after THP is disabled.

10、**安装redis依赖库**redis-4.1.0.gem。否则一会儿启动会报错。进入存放依赖库的public文件夹下。

[root@localhost public]# gem install redis-4.1.0.gem

11、安装oppenssl，进入存放oppenssl的public文件夹下，解压并安装。

[root@localhost public]# tar -zxvf openssl-1.0.2n.tar.gz   ##解压
    [root@localhost public]# cd openssl-1.0.2n  ##进入解压后的安装文件
    [root@localhost openssl-1.0.2n]# ./config -fPIC --prefix=/usr/local/openssl enable-shared ##配置安装路径
    [root@localhost openssl-1.0.2n]# make && make install  ##编辑安装

12、关闭防火墙：service friewalld stop

三、redis集群搭建

1、在public文件夹下创建redis-custer文件目录，并在redis-custer目录下创建集群文件7000 7001 7002 7003 7004 7005六个文件夹。

[root@localhost public]# mkdir redis-custer
    [root@localhost public]# cd redis-custer/
    [root@localhost redis-custer]#  mkdir 7000 7001 7002 7003 7004 7005

2、将/root/public/redis-5.0.4/src目录下的redis-cli redis-server redis-trib.rb复制到这六个文件夹中。同时将/root/public/redis-5.0.4/目录下的redis.conf 文件拷贝到这6个目录中,并对这6个redis.conf文件做修改。

[root@localhost src]# cp redis-cli redis-server redis-trib.rb /root/public/redis-custer/7000
    [root@localhost src]# cp redis-cli redis-server redis-trib.rb /root/public/redis-custer/7001
    [root@localhost src]# cp redis-cli redis-server redis-trib.rb /root/public/redis-custer/7002
    [root@localhost src]# cp redis-cli redis-server redis-trib.rb /root/public/redis-custer/7003
    [root@localhost src]# cp redis-cli redis-server redis-trib.rb /root/public/redis-custer/7004
    [root@localhost src]# cp redis-cli redis-server redis-trib.rb /root/public/redis-custer/7005   
    ##下面为复制redis.conf文件
    [root@localhost redis-5.0.4]# cp redis.conf /root/public/redis-custer/7000
    [root@localhost redis-5.0.4]# cp redis.conf /root/public/redis-custer/7001
    [root@localhost redis-5.0.4]# cp redis.conf /root/public/redis-custer/7002
    [root@localhost redis-5.0.4]# cp redis.conf /root/public/redis-custer/7003
    [root@localhost redis-5.0.4]# cp redis.conf /root/public/redis-custer/7004
    [root@localhost redis-5.0.4]# cp redis.conf /root/public/redis-custer/7005

3、修改每个集群文件夹下面的redis.conf文件

<table> 
 <tbody> 
  <tr> 
   <td> <p style="margin-left:0cm;">port&nbsp; 7000&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //端口7000,7001,7002,7003,7004,7005&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> <p style="margin-left:0cm;">bind 本机ip&nbsp; &nbsp; //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访问对应的端口，无法创建集群</p> <p style="margin-left:0cm;">daemonize&nbsp;&nbsp;&nbsp; yes&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //redis后台运行</p> <p style="margin-left:0cm;">pidfile&nbsp; /var/run/redis_7000.pid&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //pidfile文件对应7000…7005</p> <p style="margin-left:0cm;">cluster-enabled&nbsp; yes&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; //开启集群&nbsp; 把注释#去掉</p> <p style="margin-left:0cm;">cluster-config-file&nbsp; nodes_7000.conf&nbsp; &nbsp;//集群的配置&nbsp; 配置文件首次启动自动生成 7000…7005</p> <p style="margin-left:0cm;">cluster-node-timeout&nbsp; 15000&nbsp; &nbsp; &nbsp; &nbsp; //请求超时&nbsp; 默认15秒，可自行设置</p> appendonly&nbsp; yes&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//aof日志开启&nbsp; 有需要就开启，它会每次写操作都记录一条日志</td> 
  </tr> 
 </tbody> 
</table>

4、进入redis/root/public/redis-5.0.4/src目录下，给根目录下拷贝一个redis-trib.rb,用于创建集群。

[root@localhost src]# cp redis-trib.rb ../

5、分别启动redis的6个节点。

[root@localhost redis-custer]# redis-server ./7000/redis.conf 
    [root@localhost redis-custer]# redis-server ./7001/redis.conf 
    [root@localhost redis-custer]# redis-server ./7002/redis.conf 
    [root@localhost redis-custer]# redis-server ./7003/redis.conf 
    [root@localhost redis-custer]# redis-server ./7004/redis.conf 
    [root@localhost redis-custer]# redis-server ./7005/redis.conf

8、创建redis集群，执行命令redis-cli --cluster create 192.168.160.129:7000 192.168.160.129:7001 192.168.160.129:7002 192.168.160.129:7003 192.168.160.129:7004 192.168.160.129:7005

注意：如果是多台服务器一起作为redis集群，那么创建集群时的IP地址和端口号也写成相应的IP地址和端口号，这里写的IP地址和端口号要和每个集群文件下面的redis.conf文件中配置IP和端口号一致。

[root@localhost redis-5.0.4]# redis-cli --cluster create 192.168.160.129:7000 192.168.160.129:7001 192.168.160.129:7002 192.168.160.129:7003 192.168.160.129:7004 192.168.160.129:7005

9、测试redis

[root@localhost redis-5.0.4]# redis-cli -h 192.168.160.129 -c -p 7002
    192.168.160.129:7002> set name fengfeng
    OK
    192.168.160.129:7002> get name
    "fengfeng"
    192.168.160.129:7002>
