安装Ruby：

到Ruby官网：https://www.ruby-lang.org/en/downloads/

找到最新版本的Ruby

进入linux，选择一个位置存放安装包，我的位置是/opt/soft

[[email protected] soft]# pwd

/opt/soft

输入命令wget + 刚刚复制的安装包URL

[[email protected] soft]# wget https://cache.ruby-lang.org/pub/ruby/2.5/ruby-2.5.0.tar.gz

我安装的是2.2.7，解压缩：

[[email protected] soft]# tar zxf ruby-2.2.7.tar.gz

进入解压缩完成后的文件夹，执行命令：

[[email protected] ruby-2.2.7]# ./configure --prefix=/usr/local/ruby-2.2.7

[[email protected] ruby-2.2.7]# make && make install

[[email protected] ruby-2.2.7]# ln -s /usr/local/ruby-2.2.7 /bin/ruby /usr/bin/ruby

执行ruby -v可查看版本

[[email protected] soft]# cd openssl-1.1.1-pre2

[[email protected] openssl-1.1.1-pre2]# ./config --prefix=/usr/local/openssl --shared

[[email protected] openssl-1.1.1-pre2]# make

[[email protected] openssl-1.1.1-pre2]# make install

[[email protected] openssl-1.1.1-pre2]# cd /usr/local

[[email protected] local]# ls -s openssl ssl

[[email protected] local]# cd /etc/

添加黄色的哪一行代码

[[email protected] etc]# vi ld.so.conf 

/usr/local/openssl/lib

在文件最后添加黄色代码:

[[email protected] etc]# vi profile

unset i
unset -f pathmunge
export OPENSSL=/usr/local/openssl/bin
export PATH=$OPENSSL:$PATH:$HOME/bin

ldconfig

执行exec bash --login是更改生效。

[[email protected] etc]# exec bash --login

执行命令后看到下面黄色的输出就对了

参数”--replicas 1”表示每个主节点需要一个从节点（replicas前面是两个减号）

上面黄色部分，表示16384个slots都被分配给了3个Master

[OK] All 16384 slots covered.表示集群配置成功运行正常。
