Here is a quick howto for setting up nginx and php-fpm on a Debian 6 VPS. We will be using the dotdeb repository for this so a big thanks goes to the dotdeb guys for building such reliable Debian packages.

This has been tested on a Debian 6 OpenVZ minimal template:
First add the dotdeb repo to your sources.list file:

Code:

nano /etc/apt/sources.list

add this to the bottom of the file:

Code:

deb http://packages.dotdeb.org stable all

Next, add the GnuPG key to your distribution:

Code:

wget http://www.dotdeb.org/dotdeb.gpg
cat dotdeb.gpg | sudo apt-key add -
rm dotdeb.gpg

Update APT:

Code:

apt-get update

Install php and php-fpm plus some common addons:

Code:

apt-get install php5 php5-fpm php-pear php5-common php5-mcrypt php5-mysql php5-cli php5-gd

Install nginx:

Code:

apt-get install nginx

Tweak the php-fpm configuration:

Code:

nano

1.Install autoconf:

Code:

apt-get install autoconf

2.Install APC using PECL:

Code:

pecl install apc

3.After install process we have messages like this:

Code:

Build process completed successfully
Installing '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/apc.so'
install ok: channel://pecl.php.net/APC-3.0.19
configuration option "php_ini" is not set to php.ini location
You should add "extension=apc.so" to php.ini

4.Edit php.ini (via DA or directly: /usr/local/lib/php.ini)
-modify extension_dir directive:

Code:

; Directory in which the loadable extensions (modules) reside.
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613/"

-Enable extension apc.so:

Code:

extension=apc.so

5.Restart HTTPD (via DA)
6.Check in phpinfo() is apc enabled?

Code:

apc
APC Support enabled
Version 3.0.19
MMAP Support Enabled
MMAP File Mask no value
Locking type pthread mutex Locks
Revision $Revision: 3.154.2.5 $

Since there are alot of people asking for it, here is my HowTo about mod_ruid2
This is based on my Debian server with Apache 2.x.

Installing this module its no longer needed to chmod config files to 666 or upload/attachments directories to 777. Since with this module enabled everything @ HTTP will run under the user itself and not 'apache' anymore.

** If you are using mod_ruid instead of mod_ruid2, first of all remove the mod_ruid line from '/etc/httpd/conf/httpd.conf'

First, we are going to install libcap-devel
For CentOS:

yum -y install libcap-devel

For Debian:

aptitude install libcap2-dev

After this is done we are going to download and install mod_ruid2

wget http://dave.t0xic.nl/tars/mod_ruid2-0.9.3.tar.bz2
tar xjf mod_ruid2-0.9.3.tar.bz2
cd mod_ruid2-0.9.3
apxs -a -i -l cap -c mod_ruid2.c

Now, if you didn't get any errors mod_ruid2 should be installed and added to the '/etc/httpd/conf/httpd.conf ...

Forcing reboot
Linux is not Windows XP and if reboot fail you usually still connect by SSH and do something. This commands will show you how to remotely hard reboot machine. Hard reboot mean that shutdown scripts will not run and machine reboot immediately without syncing hard disk drives, shutdown applications etc, it’s more like hitting the reset button.

Code:

echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger

This commands enable sysrq and after this calls fast reboot. If you want to force shutdown machine try this.
Force shutdown

Code:

echo 1 > /proc/sys/kernel/sysrq
echo o > /proc/sysrq-trigger

Pasted from
This came handy, when I had a server that had some IO error and it can no longer read from disk, only few cached binaries into memory kept it running (kernel, SSHD, bash), I could still access the machine via SSH but can no longer do anything, forcing the reboot as mentioned above was my only resort, and it worked like ...
