解决方案：

可能是epel源问题：

1.获取php7.0的yum源

rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

2.yum search php-mysql

No match for argument: php-mysql centos无法安装php-mysql模块

============================================================== Name Matched: php-mysql ==============================================================
php-mysqlnd.x86_64 : A module for PHP applications that use MySQL databases

是名字错误：

yum install php-mysqlnd

完美解决：

No match for argument: php-mysql centos无法安装php-mysql模块
