How to compile and install PHP extension PDO under Linux (CentOS)_php tips

This article describes how to compile and install the PHP extension PDO under Linux (CentOS). Share it with everyone for your reference, the details are as follows:

Here is CentOS as an example. This should be the case for the Red Hat series of Linux methods. The steps are explained in detail below. I seriously despise articles about PDO compilation and installation that are long-winded and miscellaneous.

1. Enter the PHP package pdo extension directory (note: not the PHP installation directory)

[root@gamejzy /]# cd /tmp/lamp/php-5.3.19/ext/pdo_mysql/

Note: My php package is under /tmp/lamp/php-5.3.19

Execute phpize command

[root@gamejzy pdo_mysql]# /usr/local/php/bin/phpize

Note: /usr/local/php is my php installation directory

After executing the phpize command, configure

will appear in the pdo_mysql directory

Execute configuration

Copy code The code is as follows:

[root@gamejzy pdo_mysql]# ./configure --with-php -config=/usr/local/php/bin/php-config --with-pdo-mysql=/usr/local/mysql/

Parameter description:

--with-php-config=/usr/local/php/bin/php-config specifies the configuration when installing PHP
--with-pdo-mysql=/usr/local/mysql/ Specify the installation directory location of the MySQL database

Compile and install

[root@gamejzy pdo_mysql]# make && make install

After the compilation is completed, please pay attention to whether a message similar to the following picture appears

If a message appears indicating that the compilation and installation were successful, please pay close attention to the directory enclosed by the red line (note: the directory name may be different in different time periods).

After compilation and installation are completed, the generated pdo_mysql.so file will be placed in this directory.

2. Modify the php.ini file

Use vi to open the php.ini file of your machine, add a piece of code "extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/pdo_mysql.so", and load pdo_mysql .so file

The effect is as follows:

Save and exit editing!

3. View phpinfo()

First restart the Apache server. Use the phpinfo() function to view the installation information of php. If the following figure appears, the PDO extension is successfully installed.

That’s it!
