centos7 安装ruby

下载ruby

下载 Ruby 之后，解压到某目录下：

$ tar -xvzf ruby-2.5.1.tgz -C /usr/local   
$ cd /usr/local/ruby-2.5.1

现在，配置并编译源代码，如下所示：

$ ./configure
$ make
$ sudo make install

安装后，通过

建立软连接

ln -s /usr/local/ruby-2.5.1/ruby /usr/bin/ruby

注意： 这里要用全路径，否则会报错：Too many levels of symbolic links

验证：

[root@node1 ~]# ruby -v

ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]

[root@node1 ~]# irb
irb(main):001:0> 

开发ruby使用sublime text3 安装插件：CodeIntel，可以自动提示ruby的函数,类等,比如输入File.,它就会自动列出File的所有函数供你选择.

以及代码高亮：.Bracket Highlighter 高亮代码匹配,比如括号,双引号,do和end等等,比自带的显示更明显
