Install MongoDB in Ubuntu 12.04 with PHP driver

Install MongoDB:

sudo apt-key adv --keyserver hkp:// --recv 7F0CEB10
echo 'deb dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
sudo apt-get update
sudo apt-get install mongodb-10gen

Install MongoDB PHP driver:

sudo apt-get install php-pear php5-dev
pecl search mongo
sudo pecl install mongo

Configure MongoDB PHP driver: Create a file called /etc/php5/mods-available/mongo.ini with this content:

And create a symlink to it in /etc/php5/conf.d/:

cd /etc/php5/conf.d
sudo ln -s ../mods-available/mongo.ini 20-mongo.ini

Then restart Apache:

sudo service apache2 restart

Start, stop and restart MongoDB:

sudo service mongodb start
sudo service mongodb stop
sudo service mongodb restart

Solve “The Alias directive in … will probably never match because ir overlaps an earlier Alias”

This is a warning that happens when starting Apache2.

$ sudo service apache2 restart
 * Restarting web server apache2                                                [Wed May 08 11:55:52 2013] [warn] The Alias directive in /etc/phpmyadmin/apache.conf at line 3 will probably never match because it overlaps an earlier Alias.
 ... waiting [Wed May 08 11:55:54 2013] [warn] The Alias directive in /etc/phpmyadmin/apache.conf at line 3 will probably never match because it overlaps an earlier Alias.
                                                                         [ OK ]

It is caused because the configuration for phpMyAdmin is loaded 2 times: in /etc/apache2/conf.d/phpmyadmin.conf and /etc/apache2/apache2.conf with an include to /etc/phpmyadmin/apache.conf.

To get rid of this warning just comment out this line in /etc/apache2/apache2.conf:

Include /etc/phpmyadmin/apache.conf

Install and activate xdebug in MacPorts

First install php5-xdebug:

sudo port install php5-xdebug

Then just add these in your php.ini (probably /opt/local/etc/php5/php.ini), but first verify the file path for zend_extension option:

; NOTE: This line adds the xdebug extension. The macports install will give you the path, 
; or may even add this automatically. Be smart, look for a similar line in your config first.
; (Edit: 06/22/2012)

; General config
;Dumps local variables on exception
;Dump server variables
;Dump global variables

; Tracing

; Profiler

; Debugging. You might need to specify your host with some additional options


Useful Apache 2 and MySQL 5 service aliases for MacPorts

Those are some aliases I use to start, stop and restart Apache 2 and MySQL on my MacPorts installation done with the installation script I made some time ago. You have to edit “~/.bash_profile” file and add those lines:

alias mysql5start='sudo /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper start'
alias mysql5stop='sudo /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper stop'
alias mysql5restart='sudo /opt/local/etc/LaunchDaemons/org.macports.mysql5/mysql5.wrapper restart'

alias apache2start='sudo /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper start'
alias apache2stop='sudo /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper stop'
alias apache2restart='sudo /opt/local/etc/LaunchDaemons/org.macports.apache2/apache2.wrapper restart'

Then execute “source ~/.bash_profile” to load the new aliases or just open a new terminal window.

Using MacPorts php from command line

Some time ago I had installed Apache+MySQL using MacPorts in Mac OS X. It was all OK as long as I used the web browser to navigate thru the web pages, but as I runned PHP via CLI to execute Symfony2 commands I started having problems. It said for example that my time zone was not set, and I knew for sure that I had configured it in the php.ini file.

$ php app/console doctrine:schema:update --force

[ErrorException] Warning: date_default_timezone_get(): It is not safe to rely on the system' s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those me thods and you are still getting this warning, you most likely misspelled th e timezone identifier. We selected 'Europe/Berlin' for 'CET/1.0/no DST' ins tead in /Users/enekochan/Documents/Webs/ Monolog/Logger.php line 199


Searching the web for a solution I realized that the problem was that I was running the binary php that comes with Mac OS X, and I didn’t have the timezone configured for it. You can see where the php.ini file is by running this:

$ php -i | grep 'Configuration File'
Configuration File (php.ini) Path => /etc
Loaded Configuration File => (none)

The first solution i came up with was to use the full path for the MacPorts php binary file:

$ /opt/local/bin/php app/console doctrine:schema:update --force
$ /opt/local/bin/php -i | grep 'Configuration File'
Configuration File (php.ini) Path => /opt/local/etc/php5
Loaded Configuration File => /opt/local/etc/php5/php.ini

A better solution consists on adding to the systems path /opt/local/bin before /usr/bin. This can be done adding this to ~/.bash_profile:

PATH=/opt/local/bin:$PATH;export PATH

Then you have to close and open a new terminal or source the newly edited ~/.bash_profile:

$ source ~/.bash_profile
