This tutorial shows how you can install and run a Contao 2.10.2 web site on a Debian Squeeze or Ubuntu 11.10 system that has nginx installed instead of Apache (LEMP = Linux + nginx (pronounced "engine x") + MySQL + PHP). nginx is a HTTP server that uses much less resources than Apache and delivers pages a lot of faster, especially static files.

I do not issue any guarantee that this will work for you!

1 Preliminary Note

I want to install Contao in a vhost called www.example.com/example.com here with the document root /var/www/www.example.com/web.

You should have a working LEMP installation, as shown in these tutorials:

• Installing Nginx With PHP5 And MySQL Support On Debian Squeeze
• Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On Ubuntu 11.10

A note for Ubuntu users:

Because we must run all the steps from this tutorial with root privileges, we can either prepend all commands in this tutorial with the string sudo, or we become root right now by typing

sudo su

2 Installing APC

APC is a free and open PHP opcode cacher for caching and optimizing PHP intermediate code. It's similar to other PHP opcode cachers, such as eAccelerator and XCache. It is strongly recommended to have one of these installed to speed up your PHP page.

APC can be installed as follows:

apt-get install php-apc

If you use PHP-FPM as your FastCGI daemon (like in Installing Nginx With PHP5 (And PHP-FPM) And MySQL Support On Ubuntu 11.10), restart it as follows:

/etc/init.d/php5-fpm restart

If you use lighttpd's spawn-fcgi program as your FastCGI daemon (like in Installing Nginx With PHP5 And MySQL Support On Debian Squeeze), we must kill the current spawn-fcgi process (running on port 9000) and create a new one. Run

netstat -tap

to find out the PID of the current spawn-fcgi process:

root@server1:~# netstat -tap
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 *:sunrpc                *:*                     LISTEN      734/portmap
tcp        0      0 *:www                   *:*                     LISTEN      2987/nginx
tcp        0      0 *:ssh                   *:*                     LISTEN      1531/sshd
tcp        0      0 *:57174                 *:*                     LISTEN      748/rpc.statd
tcp        0      0 localhost.localdom:smtp *:*                     LISTEN      1507/exim4
tcp        0      0 localhost.localdom:9000 *:*                     LISTEN      1542/php5-cgi
tcp        0      0 localhost.localdo:mysql *:*                     LISTEN      1168/mysqld
tcp        0     52 server1.example.com:ssh 192.168.0.198:2462      ESTABLISHED 1557/0
tcp6       0      0 [::]:www                [::]:*                  LISTEN      2987/nginx
tcp6       0      0 [::]:ssh                [::]:*                  LISTEN      1531/sshd
tcp6       0      0 ip6-localhost:smtp      [::]:*                  LISTEN      1507/exim4
root@server1:~#

In the above output, the PID is 1542, so we can kill the current process as follows:

kill -9 1542

Afterwards we create a new spawn-fcgi process:

/usr/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -u www-data -g www-data -f /usr/bin/php5-cgi -P /var/run/fastcgi-php.pid

3 Installing Contao

The document root of my www.example.com web site is /var/www/www.example.com/web - if it doesn't exist, create it as follows:

mkdir -p /var/www/www.example.com/web

Next we download Contao (the .tar.gz version) from http://www.contao.org/download.html and place it in our document root:

cd /tmp
wget http://downloads.sourceforge.net/project/typolight/Contao/contao-2.10.2/contao-2.10.2.tar.gz
tar xvfz contao-2.10.2.tar.gz
cd contao-2.10.2/
mv * /var/www/www.example.com/web/

It is recommended to make the document root and the Contao files in it writable by the nginx daemon which is running as user www-data and group www-data:

chown -R www-data:www-data /var/www/www.example.com/web

If you haven't already created a MySQL database for Contao (including a MySQL Contao user), you can do that as follows (I name the database contao in this example, and the user is called contao_admin, and his password is contao_admin_password):

mysqladmin -u root -p create contao

mysql -u root -p

GRANT ALL PRIVILEGES ON contao.* TO 'contao_admin'@'localhost' IDENTIFIED BY 'contao_admin_password';
GRANT ALL PRIVILEGES ON contao.* TO 'contao_admin'@'localhost.localdomain' IDENTIFIED BY 'contao_admin_password';

FLUSH PRIVILEGES;

quit;

Next we create an nginx vhost configuration for our www.example.com vhost in the /etc/nginx/sites-available/ directory as follows:

vi /etc/nginx/sites-available/www.example.com.vhost

server {
       listen 80;
       server_name www.example.com example.com;
       root /var/www/www.example.com/web;
       if ($http_host != "www.example.com") {
                 rewrite ^ http://www.example.com$request_uri permanent;
       }
       index index.php index.html;
       location = /favicon.ico {
                log_not_found off;
                access_log off;
       }
       location = /robots.txt {
                allow all;
                log_not_found off;
                access_log off;
       }
       # Make sure files with the following extensions do not get loaded by nginx because nginx would display the source code, and these files can contain PASSWORDS!
        location ~* \.(tpl|html5|xhtml)$ {
                deny all;
        }
       # Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
       location ~ /\. {
                deny all;
                access_log off;
                log_not_found off;
       }
       location / {
                try_files $uri $uri/ /index.php?$args;
       }
       location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$ {
                expires max;
                log_not_found off;
       }
       location ~ \.php$ {
                try_files $uri =404;
                include /etc/nginx/fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
       }
}

Next make sure you have the following line in /etc/nginx/mime.types:

vi /etc/nginx/mime.types

[...]
        text/x-component                        htc;
[...]

To enable the vhost, we create a symlink to it from the /etc/nginx/sites-enabled/ directory:

cd /etc/nginx/sites-enabled/
ln -s /etc/nginx/sites-available/www.example.com.vhost www.example.com.vhost

Reload nginx for the changes to take effect:

/etc/init.d/nginx reload

Now we can launch the web-based Contao installer by going to http://www.example.com/contao/install.php - first you have to accept the Contao license (LGPL) :

To make sure that noone else can access the Contao installer in the future, provide a password for the installer (in addition to that, you can delete contao/install.php after successful installation):

Next fill in the database details and click on Save database settings:
