一. 安装openssl
$ tar -xzvf openssl-1.1.1s.tar.gz
$ cd openssl-1.1.1s
$ ./config -fPIC --prefix=/usr/local/openssl enable-shared
$ ./config -t
$ make && make install
二. 安装zlib-devel
$ sudo yum -y install zlib-devel
三. 添加Ruby支持(ruby2.2.2+ version)
1. 安装ruby相关依赖
$ yum -y install ruby ruby-devel rubygems rpm-build
$ ruby -v [RESULT] ruby 2.0.0p648 (2015-12-16) [x86_64-linux]
2.下载源码包（暂时不支持yum升级）
$ wget https://cache.ruby-lang.org/pub/ruby/ruby-2.5.1.tar.gz
或
$ curl -O -L https://cache.ruby-lang.org/pub/ruby/ruby-2.5.1.tar.gz
3.解压并编译安装
$ tar -zxvf ruby-2.5.1.tar.gz$ cd ruby-2.2.7
$ ./configure --prefix=/usr/local/ruby-2.5.1 --with-openssl-dir=/usr/local/openssl/ssl$ make && make install
4.创建快捷键&建立连接
$ rm -f /usr/bin/ruby #先删除旧的快捷方式重新创建
$ ln -s /usr/local/ruby-2.5.1/bin/ruby /usr/bin/ruby
$ ruby -v
[RESULT] ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
$ ln -s /usr/local/ruby-2.5.1/include /include
5.编译ruby资源包下的openssl
$ cd /home/docker/server/ruby-2.5.1/ext/openssl #切换到tar解压后的源码包下
$ ruby extconf.rb --with-openssl-include=/usr/local/openssl/include/ --with-openssl-lib=/usr/local/openssl/lib
$ make
$ make install
/usr/bin/install -c -m 0755 openssl.so ....../site_ruby/2.2.0/x86_64-linux
installing default openssl libraries
6.安装redis集群环境
$ gem install redis
