linux下php开启pdo扩展

• 前提：网页报错 

         为解决问题：Undefined class constant 'MYSQL_ATTR_INIT_COMMAND'

解决方案 ：

• 下载安装PHP_MYSQL扩展

wget http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz
tar xvf PDO_MYSQL-1.0.2.tgz
cd PDO_MYSQL-1.0.2
/usr/local/php-5.6.30/bin/phpize
./configure --with-php-config=/usr/local/php-5.6.30/bin/php-config --with-pdo-mysql=/usr/local/mysql-5.7.21/ --with-zlib-dir=/usr/local/lib
make
make install

• 报错解决/usr/local/src/PDO_MYSQL-1.0.2/php_pdo_mysql_int.h:25:19: fatal error: mysql.h: No such file or directory

ln -s /usr/local/mysql-5.7.21/include/* /usr/local/include/

• PDO_MYSQL安装成功后，继续，开启PHP对应扩展

vim /usr/local/php-5.6.30/etc/php.ini

#在文件末尾增加 extension=pdo_mysql.so

• 报错解决libmysqlclient.so.20: cannot open shared object file: No such file or directory in Unknown

ln -s /usr/local/mysql-5.7.21/lib/libmysqlclient.so.20 /usr/lib64/libmysqlclient.so.20

• 重启PHP服务

 

 Done!
