我正在尝试在运行 Centos 7.3 的服务器上安装 PHP；我已经安装了 php 5.4，并且还运行着 MySQL Server 5.6.28。当我尝试安装 php-mysql 时，它正在尝试安装 mariadb-libs 以获取依赖项，并停止并显示错误：
# yum install php-mysql

有没有办法安装没有这些库的 PHP...或者我该怎么做才能在不卸载 MySQL 服务器的情况下安装该包，因为它是站点的数据库运行的地方（这是从另一台服务器迁移的）。
更新
我正在运行 MySQL 服务器：
# mysql -u root -h 127.0.0.1 -p

答案1
php-mysql使用 mariadb 客户端库 (libmysqlclient)
php-mysqlnd使用 MySQL 原生驱动程序并提供相同的扩展集（mysql、mysqli 和 pdo_mysql），因此不依赖 libmysqlclient。
在 yum 专家模式下，从一个已安装的软件包切换到另一个
# yum shell
> remove php-mysql
> install php-mysqlnd
> run
> quit
