Enabling PostgreSQL support in PHP on Mac OS X
I'm having a terribly difficult time getting the command "pg_connect()" to work properly on my Mac. I'm currently writing a PHP script (to be executed from console) to read a PostgreSQL database and email a report.
I've gone into my php.ini
file and added
extension=pgsql.so
But, I'm met with the following error.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20090626/php_pgsql.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20090626/php_pgsql.so, 9): image not found in Unknown on line 0
PHP Fatal error: Call to undefined function pg_connect() in... (blah file here)
When running phpinfo()
, I see nothing about PostgreSQL, so what is my issue h开发者_JS百科ere?
The PHP version that comes bundled with OS X doesn't include PostgreSQL. You'll have to compile the extension yourself. Here are some instructions:
- Find your version of PHP:
php -v
. - Download the version of PHP that matches yours:
curl -O http://us.php.net/distributions/php-5.3.3.tar.gz
. (This example downloads PHP 5.3.3 but this must match your version) - Extract the archive you downloaded:
tar -xzvf php-5.3.3.tar.gz
- Change to the PostgreSQL's extension directory:
cd php-5.3.3/ext/pgsql/
- Type
phpize
. - Type
./configure
. - Type
make
. - Type
sudo make install
. - Add the extension to you
php.ini
file by addingextension=pgsql.so
. (You may already have done this) - Restart Apache.
Update for OS X Mountain Lion
Apple has removed autoconf
from the newer versions of XCode so the procedure above will fail at #5. To solve that problem:
- Type
/usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"
. - Type
sudo chown -R $USER /usr/local/Cellar
. - Type
brew update
. - Type
brew install autoconf
.
That should install autoconf
and allow you to install the module using the instructions above.
If you use home brew
, you can solve this with a command as simple as:
brew install php55-pdo-pgsql
for other php version, search with:
brew search pgsql
This worked for me with OSX 10.9.4 «Mavericks»
Install sources
Download the PHP source code. Unlike on Mountain Lion, you don’t get any headers preinstalled to link against so need to put it in /usr/include/php. Mavericks ships with PHP 5.4.17, but the latest 5.4.x source from php.net should do:
tar -jxvf php-5.4.20.tar.bz2
sudo mkdir -p /usr/include
sudo mv php-5.4.20 /usr/include/php
Configure PHP
cd /usr/include/php
./configure --without-iconv
sudo cp /etc/php.ini.default /etc/php.ini
Building a module
I needed the pdo_pgsql module - the same pattern should apply to just about any module assuming you have the necessary dependencies installed:
cd ext/pdo_pgsql
In my case I had the following error:
Cannot find autoconf. Please check your autoconf installation and the $PHP_AUTOCONF environment variable. Then, rerun this script. ERROR: `phpize' failed
So I had to use this command:
brew install autoconf
Then:
phpize
After that I tried to do: ./configure
but I had the next problem:
checking for pg_config... not found configure: error: Cannot find libpq-fe.h. Please specify correct PostgreSQL installation path
So the solution was to specify correct PostgreSQL installation path:
./configure --with-pdo-pgsql=/Library/PostgreSQL/9.3/
make
sudo make install
That copies pdo_pgsql.so to /usr/lib/php/extensions/no-debug-non-zts-20100525.
Then simply add
extension=pdo_pgsql.so to /etc/php.ini
Run php -m
to confirm everything went to plan.
For those who installed php7/ngix/postgres with homebrew
You can install the PostgreSQL module with:
brew install php70-pdo-pgsql
After that, you have to restart the php service:
brew services restart php70
OS X El Capitan users can simply upgrade their version of PHP 5.6. This is a one liner that will do that.
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.6
For php56
via brew:
brew install php56-pdo-pgsql
PostgreSQL by default is installed in a unusual place on MAC OS X:
/Library/PostgreSQL/9.3
Given the location above you can type this:
./configure --with-pgsql=/Library/PostgreSQL/9.3
I killed the whole day trying to make it work on El Capitan after I made an upgrade yesterday and it turned out that I forgot to modify httpd.conf
and change the path from the default php module (version 5.5.27) to the one I installed (version 5.6.14). This should be done in httpd.conf
by modifying your default LoadModule php5_module
path to LoadModule php5_module /usr/local/opt/php56/libexec/apache2/libphp5.so
.
Just decided to leave it here as the potential solution for those who upgrade their OS or just the PHP version and face the same problem.
For those of you having openssl error while make
here is the solution
OSX uses openssl 0.98 while installer is searching for 1.0.0
refer this link for instructions
psycopg2 installation error - Library not loaded: libssl.dylib
I downloaded PostgreSQL for Mac, and used the stack builder after installation to standup the entire EnterpriseDB Apache/PHP stack end-to-end. I mention this as a possible time saving option, probably not ideal for all situations. Should work OK if the apache and postgres shipped with Mac OS X were never started.
To keep existing apache hosted applications (i.e. pre-PostgreSQL install legacy) stable, I would just install the newer EnterpriseDB apache on port 81 (stackbuilder will prompt for new port if legacy apache instance is already running). Then, use mod_proxy in httpd.conf for the apache running on port 80 to provide seamless user experience to applications hosted on PostgreSQL.
