php centos7 install mysql and pdo

1. install mysql package for php
ref  https://www.opencli.com/php/php-use-mysqlnd-replace-libmysql

libmysql 是 PHP 沿用已久的 MySQL driver, 而在 PHP 5.3 開始, PHP 內建了 PHP 專用連接 MySQL 的 Driver — mysqlnd, 而從 PHP 5.4 之後的版本, mysqlnd 更被 PHP 作為預設安裝選項。

如果在 RHEL / CentOS 下要安裝 mysqlnd, 可以用 yum 指令完成, 但由於 php-mysqlnd (mysqlnd) 與 php-mysql (libmysql) 不能共存, 所以安裝前要先移除 php-mysql.

# yum install php-mysqlnd

1.  Oracle Instant Client

Oracle Instant Client enables applications to connect to a local or remote Oracle Database for development and production deployment. The Instant Client libraries provide the necessary network connectivity, as well as basic and high end data features, to make full use of Oracle Database. It underlies the Oracle APIs of popular languages and environments including Node.js, Python and PHP, as well as providing access for OCI, OCCI, JDBC, ODBC and Pro*C applications. Tools included in Instant Client, such as SQL*Plus and Oracle Data Pump, provide quick and convenient data access.
