快捷命令(Centos7环境特别建议该方式，因为gcc是4.8.5，gdb是7.6.1)：

yum groupinstall ‘Development Tools’

你也可以这样：

yum -y install firefox gcc gcc-c++ autoconf automake gdb git perl svn libtool flex bison pkgconfig vim subversion git lrzsz openssl curl wget curl p7zip mysql openssl-devel mysql-server mysql-devel zlib-devel curl-devel

yum install -y python-devel libxml2-devel libxslt-devel python-lxml sqlite-devel libffi-devel openssl-devel mysql-server mysql-devel zlib-devel curl-devel
