If you need or want a great full-text search engine, and you decide on Sphinx Search, here's how to install it on Ubuntu. I'm using 12.04 LTS Ubuntu Server.
This assumes two things:
- You want to use Sphinx Search
- You'll be searching the Sphinx index with PHP
Note: This is how I got it to work with PHP after a few hours of testing. There may be better ways (Installing it easy, getting PHP to work with it had a road-bump).
$ sudo apt-get install sphinxsearch
Well, that was easy. Sphinx is now installed. It's three main scripts are:
- indexer - Indexes the data based on configuration file
- searchd - Search daemon that runs in background
- search - CLI tool to test searches
Next, getting PHP to work with it. This is the tricky part. Documentation says to use PEAR/PECL. Try that, and you'll get an ugly error:
$ sudo pear install pecl/sphinx ... lots of ugly output ... blah blah blah, missing libsphinxclient
We need libsphinxclient. This means going to the binary and building it using make/make install. But fear not, this is pretty easy - and there's no need to compile php.
- Download the Source Tarball.
From there, you can follow these instructions to make libspshinxclient and install the PECL library:
$ tar -xvf sphinx-2.0.6-release.tar.gz #You're version may differ $ cd sphinx-2.0.6-release/api/libsphinxclient $ ./configure $ make $ sudo make install
Now, this should work:
$ sudo pecl install sphinx
Lastly, we need to tell php about the sphinx extension.
PHP < 5.5:
// Load sphinx for all of PHP $ echo "extension=sphinx.so" | sudo tee /etc/php5/conf.d/sphinx.ini // Finally, restart Apache $ sudo service apache2 restart
PHP >= 5.5:
$ echo "extension=sphinx.so" | sudo tee /etc/php5/mods-available/sphinx.ini // Load Sphinx in Apache2 PHP: $ sudo ln -s /etc/php5/mods-available/sphinx.ini /etc/php5/apache2/conf.d/20-sphinx.ini // Load Sphinx in php5-cli: $ sudo ln -s /etc/php5/mods-available/sphinx.ini /etc/php5/cli/conf.d/20-sphinx.ini // Finally, restart Apache $ sudo service apache2 restart
Here is a same PHP class, config file, and a simpler version of the instructions above for setting up Sphinx Search in Ubuntu.
Here's a Symfony 2 Sphinx Search package.
Here's an example of setting up Sphinx and searching with it.
