The mysql_connect() function is not available when PHP connects to mysql , reported 500 error

The following are the steps:

1. Enter the ext/mysql directory of the php source code

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

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

/application/php/bin/phpize

3. Run configure and specify the location of the php-config file (/application/php/bin/php-config) and the 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 the mysql.so extension configuration, save and exit
