PHP connection MySQL mysql_connect () function is not available, reported 500 error

I did not install the MySQL extension when I was setting up the environment, but I got an error while maintaining a project today.

Fatal error:uncaught error:call to undefined function mysql_connect ()

You can use the Phpize tool to manually compile the build mysql.so extension to resolve

Here are the steps to proceed:

1. Enter the PHP source Ext/mysql directory

cd/home/oldboy/tools/php-5.5.32/ext/mysql/

2. Run phpize to generate a configure file in this directory (PHP installation directory:/application/php/)

/application/php/bin/phpize

3. Run configure to indicate the Php-config file location (/application/php/bin/php-config) and MySQL installation directory

./configure--with-php-config=/application/php/bin/php-config--with-pdo-mysql=mysqlnd

4. Compile and install, generate mysql.so

Make && make install

5. Modify the php.ini file, add mysql.so extension configuration, save exit

Extension=mysql.so

6. Restart PHP-FPM

Service PHP-FPM Restart

7. Test, add php files to the web directory, such as/usr/local/nginx/html/mysql.php

Copy Code

<?php

$con = mysql_connect (' localhost ', ' root ', ');

if ($con) {

Die (' OK ');

}else{

Die (' Could not connect: '. Mysql_error ());

}
