When compiling and installing php under centos, sometimes we often forget Some extensions, such as pdo, mysqli, but we cannot find the corresponding extension file (.so file) in the extension directory. In this case, we can only compile and install the module, generate the corresponding so file, and then Add the corresponding extension record to php.ini and restart php

. Let’s take installing mysqli as an example.

First enter the php source code package. If you can’t find it, you can download an address here: http://us2.php.net/get/php-5.2.17.tar.gz/from/a/mirror

Unzip

tar xvzf php-5.2.17.tar.gz
cdphp-5.2.17/ext/mysqli/

Then run phpize

/usr/local/nginx_php-5.2.17/bin/phpize

in the php installation directory (search according to your own php installation directory, not necessarily this directory, if not found, You can view it according to phpinfo()

Then compile and install the mysqli extension

#./configure --prefix=/usr/local/mysqli --with-php-config=/usr/local/nginx_php-5.2.17/bin/php-config --with-mysqli=/usr/local/mysql/mysql_config

Installation

make && make install

Then the mysqli.so file has been generated in the extension directory of php

Open the php.ini file and see if there is the following content

extension_dir = "/usr/local/nginx_php-5.2.17/lib/php/extensions/no-debug-non-zts-20060613/"
