问题
执行命令 telnet 命令时，遇到了如下提示信息：
-bash: telnet: command not found
确切的说，这不能算是报错。上网查了一下解决方法，都太麻烦了。于是，自己把解决方法记录一下，方便下次查阅。
解决
执行安装命令：
yum install telnet.x86_64
结果又遇到如下报错：
Loaded plugins: fastestmirror
You need to be root to perform this command.
原来是需要切换到 root 用户，切换后再执行上述命令，搞定。
输出如下信息表示安装成功：
Loaded plugins: fastestmirror

接下来，测试一下 telnet 命令是否好用，执行如下命令：
telnet 443
输出如下信息表示命令执行成功：
Trying 220.181.38.150...

好了，至此，telnet 工具就安装成功了，是不是非常 easy ？
