thinkphp Class 'PDO' not found 错误

thinkphp Class 'PDO' not found 错误，原因mysql5.7.26缺少pdo驱动，需要安装php的pdo和pdo_mysql扩展

本文以centOS为例

1、进入PHP源码包ext/pdo目录

cd ext/pdo

2.执行/usr/local/php/bin/phpize[假设PHP的安装目录为/usr/local/php]

 /usr/local/php/bin/phpize --with-php-config=/usr/local/php/bin/php-config

3.配置扩展pdo

./configure --with-php-config=/usr/local/php/bin/php-config --enable-pdo=shared

4.编译安装pdo

make && make install

成功则出现

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/

Installing header files:          /usr/local/php/include/php/

Installing PDO headers:          /usr/local/php/include/php/ext/pdo/

说明在/usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/目录下生成了pdo.so文件

6.在php配置文件中加上

extension=”/usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/pdo.so”

2、进入PHP源码包ext/pdo_mysql目录

7.在PHP源码包中进入pdo_mysql

cd ext/pdo_mysql

8.执行/usr/local/php/bin/phpize --with-php-config=/usr/local/php/bin/php-config

9.配置pdo_mysql[假设Mysql的安装目录为/usr/local/mysql]

./configure --with-php-config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql

10.编译pdo_mysql 安装pdo_mysql

 make && make install

成功则出现

Installing shared extensions:     /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/

说明的/usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/目录下生成了pdo_mysql.so文件

12.在php配置文件中加上

extension=”/usr/local/php//lib/php/extensions/no-debug-non-zts-20060613/pdo_mysql.so”

重启php和（nginx或Apache）即可！
