Source: http://www.cyberciti.biz/faq/centos-rhel-7-redhat-linux-install-gcc-compiler-development-tools/

先檢查本機是否有安裝開發套件:
# yum group list


如果畫面上條列出來，Available Groups 內缺乏
Development Tools 的話，參照以下指令，以 root 身份安裝 開發套件

Type the following [nixcmd name="yum" as root user:
# yum -y group install "Development Tools" 

OR

$ sudo yum -y group install "Development Tools" 
If above command failed, try:
# yum -y groupinstall "Development Tools"
