由于centos默认安装的gcc是GCC 4.*.* 是不支持 C++11 的，因此有些新的程序或软件要安装就行要升级GCC，不然没法编译经过html

1、以下步骤安装不成功（yum install devtoolset-4），基本上是由于仓库不提供相应版本，请先执行yum search devtoolset查询一下linux

2、使用新的办法curl

yum -y install centos-release-scl-rh centos-release-sclurl

3、从新指向国内的源头.net

参考 https://blog.csdn.net/tao_627/article/details/77260963code

4、添加源并安装

rpm --import http://linuxsoft.cern.ch/cern/slc68/x86_64/RPM-GPG-KEY-cern \
wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo \
yum search devtoolset
