Manual Installation

For driver developers and people interested in the
latest bugfixes, you can compile the driver from the latest source
code on » Github. Go to Github and click the
“download” button. Then run:

$ tar zxvf mongo-php-driver-legacy-<commit_id>.tar.gz
$ cd mongo-php-driver-legacy-<commit_id>
$ phpize
$ ./configure
$ make all
$ sudo make install

Make the following changes to php.ini:

• Make sure the extension_dir variable is pointing to the directory
  containing mongo.so. The build will
  display where it is installing the PHP driver with output that
  looks something like:

  Installing '/usr/lib/php/extensions/no-debug-non-zts-20060613/mongo.so'
  

  Make sure that it is the same as the PHP extension directory by
  running:

  $ php -i | grep extension_dir
    extension_dir => /usr/lib/php/extensions/no-debug-non-zts-20060613 =>
                     /usr/lib/php/extensions/no-debug-non-zts-20060613
  

  If it’s not, change the extension_dir in
  php.ini or move mongo.so.

• To load the extension on PHP startup, add a
  line:

  extension=mongo.so
  

Installing on *NIX

Run:

$ sudo pecl install mongo

Add the following line to your php.ini file:

extension=mongo.so

If pecl runs out of memory while installing, make
sure memory_limit in php.ini is set to
at least 128MB.

Installing on Windows

Precompiled binaries for each release are available
from » PECL for a variety of combinations
of versions, thread safety, and VC libraries. Unzip the archive and
put php_mongo.dll in your PHP extension directory (“ext” by
default).

Add the following line to your php.ini file:

extension=php_mongo.dll

Note: Additional DLL
dependencies for Windows Users

In order for this extension to work, there are
DLL files that must
be available to the Windows system PATH.
For information on how to do this, see the FAQ entitled “How
do I add my PHP directory to the PATH on Windows“. Although
copying DLL files from the PHP folder into the Windows system
directory also works (because the system directory is by default in
the system’s PATH), this is not
recommended. This extension requires the
following files to be in the PATH:
libsasl.dll

macOS

In most cases installing from PECL is the easiest
way:

$ sudo pecl install mongo

If your system has multiple version of PHP
installed (e.g. macOS default, Homebrew, » XAMPP), note that that each
version of PHP has its own pecl command and php.ini
file.

Note: Xcode dependency for
compiling on macOS

Compiling the driver on macOS will require Xcode
developer tools, which may be installed with xcode-select --install. If that command is not
available, you may first need to install the » Command Line Tools
package.

Gentoo

Gentoo has a package for the PHP PECL driver called
dev-php/pecl-mongo, which can be installed with:

$ sudo emerge -va dev-php/pecl-mongo

If you use PECL, you may get an error that libtool
is the wrong version. Compiling from source you’ll need to run
aclocal and autoconf.

$ phpize
$ aclocal 
$ autoconf 
$ ./configure
$ make
$ sudo make install

Red Hat

This includes Fedora and CentOS.

The default Apache settings on these systems do not
let requests make network connections, meaning that the driver will
get “Permission denied” errors when it tries to connect to the
database. If you run into this, try running:

$ /usr/sbin/setsebool -P httpd_can_network_connect 1

Then restart Apache. (This issue has also occurred with
SELinux.)

Third-Party Installation Instructions

A number of people have created excellent tutorials
on installing the PHP driver.

• »  (Re)installing PHP on
  macOS

  This article by Justin Hileman details the process
  of installing PHP and additional extensions with Homebrew on macOS.
  This complements the earlier instructions on this page for
  installing the driver with Homebrew.
