Configuring Nginx for Nibbleblog 4.0.3

July 25th, 2014

This is a simple configuration example to replicate the .htaccess rules for NibbleBlog 4.0.3.

For those unfamiliar with NibbleBlog:

Nibbleblog is a powerful engine for creating blogs, all you need is PHP to work. Very simple to install and configure (only 1 step).

Nginx Configuration Example
Tested on Nginx 1.7.3

server {
    listen 0.0.0.0:80;
    root /path/to/public_html;
    server_name domain.com www.domain.com;
 
    # Directory indexing is disabled by default
    # So no need to disable it, unless you enabled it yourself
 
    # access log turned off for speed
    access_log off; #enable if you need it
    error_log /var/log/nginx/nib.error.log; #or path to your error log
 
    error_page 404 = /index.php?controller=page&action=404;
 
    # main location block
    location / {
        expires 7d;
        try_files $uri $uri/ @rewrites;
    }
 
    # rewrite rules if file/folder did not exist
    # based off rules for version 4.0.3's .htaccess
    location @rewrites {
        rewrite ^/category/([^/]+)page-([0-9+])$ /index.php?controller=blog&action=view&category=$1&number=$2 last;
        rewrite ^/category/([^/]+)/$ /index.php?controller=blog&action=view&category=$1&number=0 last;
        rewrite ^/tag/([^/]+)/page-([0-9]+)$ /index.php?controller=blog&action=view&tag=$1&number=$2 last;
        rewrite ^/tag/([^/]+)/$ /index.php?controller=blog&action=view&tag=$1&number=0 last;
        rewrite ^/page-([0-9]+)$ /index.php?controller=blog&action=view&number=$1 last;
        rewrite ^/post/([^/]+)/$ /index.php?controller=post&action=view&post=$1 last;
        rewrite ^/post-([0-9]+)/(.*)$ /index.php?controller=post&action=view&id_post=$1 last;
        rewrite ^/page/([^/]+)/$ /index.php?controller=page&action=view&page=$1 last;
        rewrite ^/feed/$ /feed.php last;
        rewrite ^/([^/]+)/$ /index.php?controller=page&action=$1 last;
 
        # if any of the redirects/urls above contain a *.php file in the url
        # then you may have to create a separate location ~ ^/post-([0-9]+)/, etc block
        # otherwise the php block will be invoked before this @rewrites block does
 
    }
 
    # cache control for static files
    location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {
        expires max;
        add_header Pragma public;
        add_header Cache-Control "public, must-revalidate, proxy-revalidate";
    }
 
    # files to block or handle differently
 
    # Don't log commonly requested files that may not always exist
    location = /robots.txt  { access_log off; log_not_found off; }
    location = /favicon.ico { access_log off; log_not_found off; }
 
    # block access to these files (shadow.php, keys.php, hidden/tmp files, xml files)
    location ~ /shadow\.php { access_log off; log_not_found off; deny all; } # block access to shadow.php
    location ~ /keys\.php   { access_log off; log_not_found off; deny all; } # block access to keys.php
    location ~ /\.          { access_log off; log_not_found off; deny all; } # block access to hidden files (starting with .)
    location ~ ~$           { access_log off; log_not_found off; deny all; } # block access to vim temp files (starting with ~)
    location ~ \.xml        { access_log off; log_not_found off; deny all; } # block access to xml files
 
    # typical PHP handling block
    # with a safeguard against passing a non-existent
    # php file to the PHP interpreter
 
    location ~ \.php$ {
        try_files $uri =404;
 
        fastcgi_param  QUERY_STRING       $query_string;
        fastcgi_param  REQUEST_METHOD     $request_method;
        fastcgi_param  CONTENT_TYPE       $content_type;
        fastcgi_param  CONTENT_LENGTH     $content_length;
 
        fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
        fastcgi_param  SCRIPT_FILENAME    $request_filename;
        fastcgi_param  REQUEST_URI        $request_uri;
        fastcgi_param  DOCUMENT_URI       $document_uri;
        fastcgi_param  DOCUMENT_ROOT      $document_root;
        fastcgi_param  SERVER_PROTOCOL    $server_protocol;
 
        fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
        fastcgi_param  SERVER_SOFTWARE    nginx;
 
        fastcgi_param  REMOTE_ADDR        $remote_addr;
        fastcgi_param  REMOTE_PORT        $remote_port;
        fastcgi_param  SERVER_ADDR        $server_addr;
        fastcgi_param  SERVER_PORT        $server_port;
        fastcgi_param  SERVER_NAME        $server_name;
 
        fastcgi_pass 127.0.0.2:9000;
 
        #fastcgi_pass unix:/tmp/php.sock; 
        #use the above line instead if running php-fpm on a socket
    }
 
}

This should work pretty well as long as the newest NibbleBlog does not utilize php file names in the friendly urls (from my testing, it no longer does that).

Also Friendly URLs are not enabled by default in NibbleBlog, you need to enable it under SEO tab under settings. (ignore the instructions regarding .htaccess since you’re not using apache).

Nginx Configuration Examples

March 31st, 2011

Here are a number of Nginx configurations for common scenarios that should help make things easier to get started with. This page will grow as needed.

A quick and easy starter example

First one is for most of you fly-by and cut-and-paste type of people. If you’re using a typical /sites-enabled/default type of configuration, replace the content of that file with this. Make sure to change the root path and your php port/path if it differs.

server {
	# .domain.com will match both domain.com and anything.domain.com
	server_name .example.com;
 
	# It is best to place the root of the server block at the server level, and not the location level
	# any location block path will be relative to this root. 
	root /usr/local/www/example.com;
 
	# It's always good to set logs, note however you cannot turn off the error log
	# setting error_log off; will simply create a file called 'off'.
	access_log /var/log/nginx/example.access.log;
	error_log /var/log/nginx/example.error.log;
 
	# This can also go in the http { } level
	index index.html index.htm index.php;
 
	location / { 
		# if you're just using wordpress and don't want extra rewrites
		# then replace the word @rewrites with /index.php
		try_files $uri $uri/ @rewrites;
	}
 
	location @rewrites {
		# Can put some of your own rewrite rules in here
		# for example rewrite ^/~(.*)/(.*)/? /users/$1/$2 last;
		# If nothing matches we'll just send it to /index.php
		rewrite ^ /index.php last;
	}
 
	# This block will catch static file requests, such as images, css, js
	# The ?: prefix is a 'non-capturing' mark, meaning we do not require
	# the pattern to be captured into $1 which should help improve performance
	location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {
		# Some basic cache-control for static files to be sent to the browser
		expires max;
		add_header Pragma public;
		add_header Cache-Control "public, must-revalidate, proxy-revalidate";
	}
 
	# remove the robots line if you want to use wordpress' virtual robots.txt
	location = /robots.txt  { access_log off; log_not_found off; }
	location = /favicon.ico { access_log off; log_not_found off; }	
 
	# this prevents hidden files (beginning with a period) from being served
	location ~ /\.          { access_log off; log_not_found off; deny all; }
 
	location ~ \.php {
        	fastcgi_param  QUERY_STRING       $query_string;
        	fastcgi_param  REQUEST_METHOD     $request_method;
	        fastcgi_param  CONTENT_TYPE       $content_type;
	        fastcgi_param  CONTENT_LENGTH     $content_length;
 
	        fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
	        fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
	        fastcgi_param  REQUEST_URI        $request_uri;
	        fastcgi_param  DOCUMENT_URI       $document_uri;
	        fastcgi_param  DOCUMENT_ROOT      $document_root;
	        fastcgi_param  SERVER_PROTOCOL    $server_protocol;
 
        	fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
	        fastcgi_param  SERVER_SOFTWARE    nginx;
 
        	fastcgi_param  REMOTE_ADDR        $remote_addr;
	        fastcgi_param  REMOTE_PORT        $remote_port;
	        fastcgi_param  SERVER_ADDR        $server_addr;
	        fastcgi_param  SERVER_PORT        $server_port;
	        fastcgi_param  SERVER_NAME        $server_name;
 
	        fastcgi_pass 127.0.0.1:9000;
	}
}

As for the rest of you, read on for some more goodies and other configuration examples.

Making the PHP inclusion easier

For the purpose of PHP I’ve created a php.conf in the same folder with nginx.conf, this file DOES NOT go into the same folder as your virtual host configuration for example if nginx.conf is in /etc/nginx/ , then php.conf goes into /etc/nginx/ not /etc/nginx/sites-enabled/.

If you are not using PHP-FPM, you really should be as opposed to the old spawn-fcgi or php-cgi methods. For debian lenny/squeeze dotdeb makes php5-fpm available, FreeBSD already includes it in the PHP 5.2 and 5.3 ports.

location ~ \.php {
        # for security reasons the next line is highly encouraged
        try_files $uri =404;
 
        fastcgi_param  QUERY_STRING       $query_string;
        fastcgi_param  REQUEST_METHOD     $request_method;
        fastcgi_param  CONTENT_TYPE       $content_type;
        fastcgi_param  CONTENT_LENGTH     $content_length;
 
        fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
 
        # if the next line in yours still contains $document_root
        # consider switching to $request_filename provides
        # better support for directives such as alias
        fastcgi_param  SCRIPT_FILENAME    $request_filename;
 
        fastcgi_param  REQUEST_URI        $request_uri;
        fastcgi_param  DOCUMENT_URI       $document_uri;
        fastcgi_param  DOCUMENT_ROOT      $document_root;
        fastcgi_param  SERVER_PROTOCOL    $server_protocol;
 
        fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
        fastcgi_param  SERVER_SOFTWARE    nginx;
 
        fastcgi_param  REMOTE_ADDR        $remote_addr;
        fastcgi_param  REMOTE_PORT        $remote_port;
        fastcgi_param  SERVER_ADDR        $server_addr;
        fastcgi_param  SERVER_PORT        $server_port;
        fastcgi_param  SERVER_NAME        $server_name;
 
        # If using a unix socket...
        # fastcgi_pass unix:/tmp/php5-fpm.sock;
 
        # If using a TCP connection...
        fastcgi_pass 127.0.0.1:9000;
}

I prefer to use a unix socket, it cuts out the TCP overhead, and increases security since file-based permissions are stronger. In php-fpm.conf you can change the listen line to /tmp/php5-fpm.sock, and should uncomment the listen.owner, listen.group and listen.mode lines.

REMEMBER: Set cgi.fix_pathinfo to 0 in the php.ini when using Nginx with PHP-FPM/FastCGI, otherwise something as simple as /forum/avatars/user2.jpg/index.php could be used to execute an uploaded php script hidden as an image.

Path_Info
If you must use PATH_INFO and PATH_TRANSLATED then add the following within your location block above (make sure $ does not exist after \.php or /index.php/some/path/ will not match):

	fastcgi_split_path_info ^(.+\.php)(/.+)$;
	fastcgi_param  PATH_INFO          $fastcgi_path_info;
	fastcgi_param  PATH_TRANSLATED    $document_root$fastcgi_path_info;

It is advised however to update your script to use REQUEST_URI instead.

Optional Config – Drop

You can also have a file called drop.conf in the same folder with nginx.conf with the following:

	location = /robots.txt  { access_log off; log_not_found off; }
	location = /favicon.ico { access_log off; log_not_found off; }	
	location ~ /\.          { access_log off; log_not_found off; deny all; }
	location ~ ~$           { access_log off; log_not_found off; deny all; }

Using include drop.conf; at the end of your server block will include these. The first two simply turn off access logs and prevents logging an error if robots.txt and favicon.ico are not found, which is something a lot of browsers ask for. WordPress typically uses a virtual robots.txt so you may omit the first line if needed so that the request is passed back to wordpress.

The third line prevents nginx from serving any hidden unix/linux files, basically any request beginning with a period.

And the forth line is mainly for people who use vim, or any other command line editor that creates a backup copy of a file being worked on with a file name ending in ~. Hiding this prevents someone from accessing a backup copy of a file you have been working on.

Sample Nginx Configurations

Simple Configuration with PHP enabled

Here we have a very simple starting configuration with PHP support. I will provide most of the comments here for the basic lines. The other sample configurations won’t be as heavily commented.

server {
	# This will listen on all interfaces, you can instead choose a specific IP
	# such as listen x.x.x.x:80;  Setting listen 80 default_server; will make
	# this server block the default one if no other blocks match the request
	listen 80;
 
	# Here you can set a server name, you can use wildcards such as *.example.com
	# however remember if you use server_name *.example.com; You'll only match subdomains
	# to match both subdomains and the main domain use both example.com and *.example.com
	server_name example.com www.example.com;
 
	# It is best to place the root of the server block at the server level, and not the location level
	# any location block path will be relative to this root. 
	root /usr/local/www/example.com;
 
	# It's always good to set logs, note however you cannot turn off the error log
	# setting error_log off; will simply create a file called 'off'.
	access_log /var/log/nginx/example.access.log;
	error_log /var/log/nginx/example.error.log;
 
	location / { 
		# Rewrite rules and other criterias can go here
		# Remember to avoid using if() where possible (http://wiki.nginx.org/IfIsEvil)
	}
 
	# This block will catch static file requests, such as images, css, js
	# The ?: prefix is a 'non-capturing' mark, meaning we do not require
	# the pattern to be captured into $1 which should help improve performance
	location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {
		# Some basic cache-control for static files to be sent to the browser
		expires max;
		add_header Pragma public;
		add_header Cache-Control "public, must-revalidate, proxy-revalidate";
	}
 
	# We can include our basic configs here, as you can see its much easier
	# than pasting out the entire sets of location block each time we add a vhost
 
	include drop.conf;
	include php.conf;
}

WordPress Simple (Not using file-based caching or special rewrites)
This can also be used with W3 Total Cache if you’re using Memcache or Opcode Caching.

server {
	listen 80;
 
	server_name example.com www.example.com;
 
	root /usr/local/www/example.com;
 
	access_log /var/log/nginx/example.access.log;
	error_log /var/log/nginx/example.error.log;
 
	location / { 
		try_files $uri $uri/ /index.php; 
	}
 
	location /search { limit_req zone=kbeezieone burst=3 nodelay; rewrite ^ /index.php; }
 
	fastcgi_intercept_errors off;
 
	location ~* \.(?:ico|css|js|gif|jpe?g|png)$ {
		expires max;
		add_header Pragma public;
		add_header Cache-Control "public, must-revalidate, proxy-revalidate";
	}
 
	include php.conf;
 
	# You may want to remove the robots line from drop to use a virtual robots.txt
	# or create a drop_wp.conf tailored to the needs of the wordpress configuration
	include drop.conf;
}

WordPress w/ W3 Total Cache using Disk (Enhanced)
The following rules have been updated to work with W3TC 0.9.2.8, in some cases $host may need to be replaced with your domain name.

server {
	listen 80;
 
	server_name example.com www.example.com;
 
	root /usr/local/www/example.com;
 
	access_log /var/log/nginx/example.access.log;
	error_log /var/log/nginx/example.error.log;
 
	# the next two location blocks are to ensure gzip encoding is turned off
	# for the serving of already gzipped w3tc page cache
	# normally gzip static would handle this but W3TC names them with _gzip
