How does linux php add mysqli extensions?

Install the mysqli extension for php on linux

Php in the lamp environment does not extend the extension library of mysqli, so you can use the phpinfo () function in the php code to view the details of your php, such as what extensions are available, what version of php is, and so on.

So I started installing the mysqli extension for php on linux.

(1) find the mysqli extension in the ext directory under the php installation package:

If you can't remember where your php installation package is, you can try using the

Find /-name mysqli

Look for it, and if you can't find it, you can download a php installation package from the php official website, and then unzip it or download the name of the package directly in linux using the path saved by yum install-- downloadonly-- downloaddir=. For example:

Yum install-downloadonly-downloaddir=/root php

Attach common decompression commands:

Zip format: unzip compressed file name

Gzip format: gzip-d compressed file name

Tar.gz format: tar-zxvf compressed file name

Tar.bz2 format: tar-jxvf compressed file name

Rpm format: rpm2cpio compressed file name | cpio-p

The result should be as follows:

(2) generate mysqli.so extension files

First use the find command to find the location of the phpize:

Find /-name phpize

Mine is in / usr/bin/phpize.

Then run phpize directly under the mysqli directory

/ usr/bin/phpize

(note: if you do not run phpize in the mysqli directory, you will report the error Cannot find conf.m4.)

There may also be other errors, such as phpize Can't find PHP headers in / usr/include/php, which is caused by not installing php-devel or php-pear or gcc, etc., just install it with yum.

Next, use these commands:

. / configue-prefix=/usr/local/mysqlimake & & make install

If normal, the system will return a path under which is the mysql.so extension file we want

(3) modify php.ini configuration file

Find your php.ini configuration file, usually under / usr/local/lib, or find if you can't find it. And then

Vi php.ini

Add to the last line of php.ini

Extension=/usr/local/php/lib/php/extensions/no-debug-non-zts-20100525/mysqli.so

The string of paths in front of mysqli.so fill in the path returned by the system.

Finally restart apache
