Bloggitation

Preparation

I added PHP to bbox512 nginx . For Debian/Ubuntu it needed FastCGI:

# apt-get install libfcgi0

RTFM

• Init-script for php-cgi in external FASTCGI Mode
• Nginx, PHP and a PHP FastCGI daemon init script
• bye Redskin, zdravstvujte Redstar

Installation

# cd /etc/default/
# wget -O php-fastcgi http://zhware.net/files/nginx/php-fastcgi.txt
# cd /etc/init.d/
# wget -O php-fastcgi http://zhware.net/files/nginx/php-fastcgi.rc.txt
# chmod 755 php-fastcgi
# cd /opt/nginx/conf/sites/
# wget -O static.conf http://zhware.net/files/nginx/sites/static.conf.txt
# /etc/init.d/php-fastcgi start
# kill -HUP `cat /opt/nginx/logs/nginx.pid`

In fact it’s just starting FastCGI PHP instances and making small changes to the sites/static.conf to process files with .php extension:

location ~ \.php$ {
  fastcgi_pass 127.0.0.1:9000;
  fastcgi_index index.php;
  fastcgi_param SCRIPT_FILENAME /opt/nginx/html$fastcgi_script_name;
  fastcgi_param QUERY_STRING $query_string;
  fastcgi_param REQUEST_METHOD $request_method;
  fastcgi_param CONTENT_TYPE $content_type;
  fastcgi_param CONTENT_LENGTH $content_length;
}

There is a new version of the nginx web server – nginx-0.5.24 . Too many upgrades recently :( From the changelog:

Bugfix: a part of response body may be passed uncompressed if gzip was used; bug appeared in 0.5.23.

I have a small ugly shell script for upgrading:

#!/bin/sh
VER=0.5.24
if [ ! -d ~/Work/nginx-${VER} ]; then
  cd ~/Work
  wget http://sysoev.ru/nginx/nginx-${VER}.tar.gz && \
  tar xvzf nginx-${VER}.tar.gz
fi
if [ -d ~/Work/nginx-${VER} ]; then
  cd ~/Work/nginx-${VER} && ./configure --prefix=/opt/nginx \
     --with-openssl=/usr/lib/ --with-sha1=/usr/lib \
     --with-http_realip_module --with-http_ssl_module && make
fi

The interesting part is after the installation – upgrade the server executable “on the fly” , without restarting:

% cd ~/Work/nginx-0.5.24
% sudo make install
% sudo kill -USR2 `cat /opt/nginx/logs/nginx.pid`
% tail -f /opt/nginx/logs/error.log

Well done software = happy sysadmin = happy users :)

I put some notes for nginx on my wiki .

The rails system administration is like waves – somebody found a new software and the community just fulfill it. Maybe there must be some name for this effect. Something like digg-effect but maybe Rails wave hahaha.

First there was lighttpd , now nginx comming. Maybe your piece of code will be the next. Are your ready? ;)
