手动部署LNMP环境（CentOS 7）时，在进行到安装PHP遇到的问题

跟着阿里给的操作手册上的提示安装PHP：yum -y install php70w-devel php70w.x86_64 php70w-cli.x86_64 php70w-common.x86_64 php70w-gd.x86_64 php70w-ldap.x86_64 php70w-mbstring.x86_64 php70w-mcrypt.x86_64 php70w-pdo.x86_64 php70w-mysqlnd php70w-fpm php70w-opcache php70w-pecl-redis php70w-pecl-mongodb 然后报错：Could not retrieve mirrorlist https://mirrors.iuscommunity.org/mirrorlist?repo=ius-centos7&arch=x86_64&protocol=http error was 14: curl#6 - "Could not resolve host: mirrors.iuscommunity.org; Unknown error" 怀疑时DNS的问题，然后区 /etc/resolv.conf里添加了nameserver 8.8.8.8，还是同样报错。。。有木有大佬帮帮我。。。
