Since 3 years I’m completely into Nginx. For some reason I was always struggling with Apache, and that kept me from running my own server. But then a colleague told me about Nginx, and how great it was. So I looked into it, and the things I read were great. Compared to Apache, Nginx is smaller in size, it multiplies the performance remarkably by recducing the RAM and CPU usage for real time applications and it’s very flexible. Of course Apache will also have its advantages, but the fact I can’t come up with one says enough (about me, or Apache ;-)).

So today I’m going to show you how to setup Nginx with PHP 5 and MySQL on Ubuntu 12.04. It’s really not that difficult. Let’s start with Nginx.

1
sudo apt-get install nginx -y

That’s it. But now we want to configure Nginx. I normally use Sublime Text 2 as a text editor, because VI hates me (or I hate VI, really hard to tell). But on a remote server sublime is not really an option, so I will just use nano. Feel free to use the editor you prefer.

You can download the config here.

        try_files $uri $uri/ =404;
    }
}

Now we need to reload Nginx.

1
sudo service nginx reload

Try http://localhost/ (or http://your-server-ip-address) and hopefully you will see the welcome page of Nginx. Nice! Next, MySQL. Just follow the on screen instructions.

1
sudo apt-get install mysql-server mysql-client -y

To have a secure installation, we execute the following command:

1
sudo mysql_secure_installation

Follow the instructions. Start by entering your MySQL root password. If you did not set one yet, do it! It’s just that easy. So we can continue with PHP.

1
sudo apt-get install php5-fpm php5-cli php5-mysql -y

If you don’t want to run PHP from console, you can skip php5-cli. If you are planning to use the Symfony2 framework I would suggest you keep it, you will need it. By default fpm and cli use their own php.ini configuration file. I usualy want them to use the same one. If you want that too, do the following:

1
2
3
cd /etc/php5/cli
sudo mv php.ini php.ini.backup
sudo ln -s ../fpm/php.ini

Once php-fpm is installed, we need to configure Nginx again.

1
2
cd /etc/nginx
sudo nano nginx.conf

Add the following to the http {} part.

1
2
3
4
# Upstream to abstract back-end connection(s) for PHP
upstream php {
    server unix:/tmp/php5-fpm.sock;
}

Prepare the default site so it can serve PHP pages (needs to be in the server {} part).

sudo nano /etc/nginx/sites-available/default

# pass the PHP scripts to FPM socket
location ~ \.php$ {
    try_files $uri =404;
 
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
     
    fastcgi_pass php;
 
    fastcgi_index index.php;
 
    fastcgi_param SCRIPT_FILENAME /usr/share/nginx/www$fastcgi_script_name;
    fastcgi_param DOCUMENT_ROOT /usr/share/nginx/www;
 
    # send bad requests to 404
    fastcgi_intercept_errors on;
 
    include fastcgi_params;
}

Open /etc/php5/fpm/pool.d/www.conf and look for the following line ..

1
2
cd /etc/php5/fpm/pool.d
sudo nano www.conf
1
listen = 127.0.0.1:9000

.. and change it into ..

1
listen = /tmp/php5-fpm.sock

Save and restart both Nginx and PHP-FPM.

1
2
sudo service nginx restart
sudo service php5-fpm restart

Create a PHP file in your web root.

1
nano /usr/share/nginx/www/index.php
1
2
3
4
5
<?php
 
phpinfo();
 
?>

Save the file and refresh http://localhost/ (or http://your-server-ip-address). If everything goes well you have a nice page with your PHP configuration explained, if not you can replace “/tmp/php5-fpm.sock” by “/var/run/php5-fpm.sock” in both /etc/nginx/nginx.conf and /etc/php5/fpm/pool.d/www.conf and reload nginx and php5-fpm (possible solution by Flávio Moringa, thnx Flávio!).

The final thing to do is install phpMyAdmin.

1
sudo apt-get install phpmyadmin -y

Go to your web root and link phpMyAdmin.

1
2
cd /usr/share/nginx/www
sudo ln -s /usr/share/phpmyadmin

Now you should be able to go to http://localhost/phpmyadmin (or http://your-server-ip-address/phpmyadmin). In a production environment I try not to use phpMyAdmin, and if I really need it I use another alias. For example poiul. It makes it harder for others to find it.
