Nginx (pronounced "engine x") is a free, open-source, high-performance HTTP server. Nginx is known for its stability, rich feature set, simple configuration, and low resource consumption. This tutorial shows how you can install Nginx on an OpenSUSE 12.2 server with PHP5 support (through PHP-FPM) and MySQL support.

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

1 Preliminary Note

In this tutorial I use the hostname server1.example.com with the IP address 192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.

2 Installing MySQL 5

First we install MySQL 5 like this:

zypper install mysql-community-server mysql-community-server-client

Then we create the system startup links for MySQL (so that MySQL starts automatically whenever the system boots) and start the MySQL server:

systemctl enable mysql.service
systemctl start mysql.service

Now check that networking is enabled. Run

netstat -tap | grep mysql

It should show something like this:

server1:~ # netstat -tap | grep mysql
tcp        0      0 *:mysql                 *:*                     LISTEN      2059/mysqld
server1:~ #

If it does not, edit /etc/my.cnf and comment out the option skip-networking:

vi /etc/my.cnf

[...]
#skip-networking
[...]

and restart your MySQL server:

systemctl restart mysql.service

(If you get the message You do not have a valid vim binary package installed. Please install either "vim", "vim-enhanced" or "gvim"., please run

zypper install vim

to install vi and try again. )

Run

mysql_secure_installation

to set a password for the user root (otherwise anybody can access your MySQL database!):

server1:~ # mysql_secure_installation




NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): <-- ENTER
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] <-- Y
New password: <-- fill in your desired MySQL root password
Re-enter new password: <-- confirm that password
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] <-- Y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] <-- Y
 ... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] <-- Y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] <-- Y
 ... Success!

Cleaning up...



All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!

3 Installing Nginx

Nginx is available as a package for OpenSUSE 12.2 which we can install as follows:

zypper install nginx-1.0

Then we create the system startup links for nginx and start it:

systemctl enable nginx.service
systemctl start nginx.service

Type in your web server's IP address or hostname into a browser (e.g. http://192.168.0.100), and you should see the following page:

You get a 403 forbidden error because on OpenSUSE 12.2, the default nginx document root is /srv/www/htdocs, and there's no index page in /srv/www/htdocs.

4 Installing PHP5

We can make PHP5 work in nginx through PHP-FPM (PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites) which we install as follows:

zypper install php5-fpm

Before we start PHP-FPM, rename /etc/php5/fpm/php-fpm.conf.default to /etc/php5/fpm/php-fpm.conf:

mv /etc/php5/fpm/php-fpm.conf.default /etc/php5/fpm/php-fpm.conf

Change the permissions of PHP's session directory:

chmod 1733 /var/lib/php5

Then open /etc/php5/fpm/php-fpm.conf...

vi /etc/php5/fpm/php-fpm.conf

... and change error_log to /var/log/php-fpm.log:

[...]
error_log = /var/log/php-fpm.log
[...]

There's no php.ini file for PHP-FPM under OpenSUSE 12.2, therefore we copy the CLI php.ini:

cp /etc/php5/cli/php.ini /etc/php5/fpm/

Next open /etc/php5/fpm/php.ini...

vi /etc/php5/fpm/php.ini

... and set cgi.fix_pathinfo to 0:

[...]
; cgi.fix_pathinfo provides *real* PATH_INFO/PATH_TRANSLATED support for CGI.  PHP's
; previous behaviour was to set PATH_TRANSLATED to SCRIPT_FILENAME, and to not grok
; what PATH_INFO is.  For more information on PATH_INFO, see the cgi specs.  Setting
; this to 1 will cause PHP CGI to fix its paths to conform to the spec.  A setting
; of zero causes PHP to behave as before.  Default is 1.  You should fix your scripts
; to use SCRIPT_FILENAME rather than PATH_TRANSLATED.
; http://php.net/cgi.fix-pathinfo
cgi.fix_pathinfo=0
[...]

Next create the system startup links for php-fpm and start it:

systemctl enable php-fpm.service
systemctl start php-fpm.service

PHP-FPM is a daemon process that runs a FastCGI server on port 9000, as you can see in the output of

netstat -tapn
