Nginx + Slim Framework + phpMyAdmin on Ubuntu

Yesterday I was giving Slim Framework a test ride on my Ubuntu machine. But the machine was not ready with Nginx, or phpMyAdmin (I needed it to check the output of an ORM called RedBean). So I'm writing what I did exactly for my reference and for other's benefit.

First, in case you don't have any of the following packages, go ahead and do it


Install MySQL
sudo apt-get install mysql-server php5-mysql

and remember your root password you will enter in the installation process.

Install Nginx
sudo apt-get install nginx

Install PHP-FPM (PHP FastCGI Process Manager)
sudo apt-get install php5-fpm

Install phpMyAdmin
sudo apt-get install phpmyadmin

During installation, you will be asked to choose your web server (apache2/lighttpd). But since we will use Nginx, just press the TAB key then Enter. Then you will be asked if you want to proceed with phpMyAdmin database configurations, choose yes and continue then enter your MySQL root password when asked to.



sudo nano /etc/php5/fpm/php.ini

or as I prefer
sudo gedit /etc/php5/fpm/php.ini

Find the line, cgi.fix_pathinfo=1. Uncomment it and change the 1 to 0.

sudo gedit /etc/php5/fpm/pool.d/www.conf

and find the value given to listen =, to be used later in Nginx configuration.
It should be /var/run/php5-fpm.sock or 

Now restart fpm
sudo service php5-fpm restart


Now let's configure Nginx for both phpMyAdmin and Slim Framework project.

sudo gedit /etc/nginx/sites-enabled/default

And add the configurations for both phpMyAdmin and the Slim Framework project.

server {
    listen 80;
    server_name phpmyadmin.local;
    root /usr/share/phpmyadmin;
    index index.php;
    location / {
        try_files $uri $uri/ /index.html;
    # pass the PHP scripts to FastCGI server listening on the php-fpm socket
    location ~ \.php$ {
        try_files $uri =404;
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;       

server {
    listen 80;
    server_name slimtest.local;
    root /home/madly/slim;
    try_files $uri /index.php;
    # pass the PHP scripts to FastCGI server listening on the php-fpm socket
    location /index.php {
        fastcgi_connect_timeout 3s;     # default of 60s is just too long
        fastcgi_read_timeout 10s;       # default of 60s is just too long
        include fastcgi_params;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;      

Now let's restart Nginx server to apply the changes
sudo service nginx restart

Notes on these server configs:

1- The fastcgi_pass value is set to unix:/var/run/php5-fpm.sock because of the value I mentioned earlier in fpm configs. It may be

2- I chose to listen to port 80 but with different server names. So I must edit my hosts file
sudo gedit /etc/hosts
and add these two lines phpmyadmin.local slimtest.local 

3- During my tests with these configs, I had the css/img files accessible in my project with paths like
<link rel="stylesheet" type="text/css" href="/css/main.css">
by having a project structure like this

A problem I had:
The following day I had a problem with a project giving me the page "no input file specified". After inspecting the "/var/log/nginx/error.log" file, I found "(13: Permission denied)" errors. So I had to add extra permissions to the project:
chmod -R 755 ./
