Intro
- uses an asynchronous event-driven model which provides predictable performance under load
- efficiently serve static content such as HTML and media files
- hands off dynamic content to CGI, FastCGI, or other web servers such as Apache, content is then passed back to NGINX for delivery to the client
- directives (configuration options) are organized into groups known as blocks/contexts
- lines preceded by a # character are comments
- lines containing directives must end with a ;
- VirtualHost is an Apache term, NGINX does not have Virtual hosts, it has “Server Blocks” that use the server_name and listen directives to bind to tcp sockets
- /etc/nginx/ - configuration files
- /etc/nginx/nginx.conf - primary configuration file
- files outside any block are in main context
- events and http blocks are areas for additional directives, and they also exist in the main context
- http - directives for handling web traffic, universal because they are passed on to all website configurations NGINX serves
- include /etc/nginx/conf.d/*.conf; - each website hosted with NGINX should have its own configuration file in /etc/nginx/conf.d/, with the name formatted as example.com.conf, sites which are disabled (not being served by NGINX) should be named example.com.conf.disabled
- include /etc/nginx/sites-enabled/*; - ../sites-enabled/ folder contains symlinks to the site configuration files stored in /etc/nginx/sites-available/, sites in sites-available can be disabled by removing the symlink to sites-enabled
- /etc/nginx/conf.d/default.conf OR etc/nginx/sites-enabled/default - example configuration file
- sites configuration file
- listen directive tells NGINX the hostname/IP and the TCP port where it should listen for HTTP connections., default_server means this virtual host will answer requests on port 80 that dont specifically match another virtual hosts listen statement, the second statement listens over IPv6 and behaves similarly
- server_name directive allows multiple domains to be served from a single IP address, server decides which domain to serve based on the request header it receives
- you typically should create one file per domain or site you want to host on server
- you can specify server names that are not valid domain names, HTTP header are used to answer requests, regardless of whether the domain name is valid or not - useful for LAN servers, or if you already know all of the clients that will be making requests of the server, this includes front-end proxy servers with /etc/hosts entries configured for the IP address on which NGINX is listening
- location setting lets you configure how to respond to requests for resources within the server, like the server_name directive tells how to process requests for the domain, location directives cover requests for specific files and folders, such as http://example.com/blog/, match any part of an HTTP request that comes after the host segment
- location directive followed by a tilde (~) performs a RegEx match, case-sensitive, Perl Compatible Regular Expressions (PCRE), ~* - case-insensitive, ^~ - stop searching for more specific matches and use the directives here instead, = - exact match
- 1 - exact match
- 2 - literal string OR ^~
- 3 - RegEx
- 4 - if no RegEx, then most specific literal string match
- make sure each file and folder under a domain will match at least one location directive
- commands
/usr/bin/nginx - start/usr/bin/nginx -s stop - stop/usr/bin/nginx -s reload - reloadsudo service nginx status OR sudo systemctl status nginxsudo service nginx start OR sudo systemctl start nginx- check apache:
sudo service apache2 status OR sudo systemctl status apache2
sudo service apache2 stop OR sudo systemctl stop apache2sudo nestat -plunt OR sudo ss -plunt- LOGS:
/var/log/nginx/access.log OR /var/log/nginx/error.log
- configuration test:
sudo nginx -t
- namei -om /path/to/check - display all the permissions on a path
- check browser cache
- ADD mime.types for specific file
- if you do not explicitly set "underscores_in_headers on" NGINX will silently drop HTTP headers with underscores
- dont use the default document root for any site-critical files
- never use a hostname in a listen directive

PHP FastCGI
- this guide assume PHP FPM already installed and configured either using tcp port (127.0.0.1:9000) or unix socket (/var/run/php-fpm.sock)
- restart and test
<?php var_export($_SERVER)?< with /test.php , /test.php/ , /test.php/foo/test.php/foo/bar.php , /test.php/foo/bar.php?v=1
- pay attention to the value of REQUEST_URI, SCRIPT_FILENAME, SCRIPT_NAME, PATH_INFO and PHP_SELF
- 1) location regex capable to handle PATH_INFO and properly check that the extension indeed .php (not .phps) whether there is PATH_INFO or not
- 2) fastcgi_split_path_info regex capable to correctly handle request like /test.php/foo/blah.php or /test.php/
- 3) the if lets NGINX check whether the *.php does indeed exist to prevent NGINX to feeding PHP FPM non php script file (like uploaded image)
- 4) SCRIPT_FILENAME parameter is required as it is passed to PHP FPM to determine the script name, for a lot of Linux distributions, this parameter has been added in fastcgi_params file, i.e. /etc/nginx/fastcgi_params``so the users could import all the CGI params via the ``include directive, i.e. include fastcgi_params, but for some distributions, such as CentOS, this parameter does not exist in fastcgi_params file, if this parameter is not set, PHP FPM responses 200 OK with empty content, and there is no error or warning. For more informaton about the CGI params, please refer to nginx beginners guide, $_SERVER in PHP and RFC3875
- 5) if you see a blank page in browser, please check if SCRIPT_FILENAME parameter is set
- 6) this guide run fine on php.ini with cgi.fix_pathinfo = 1 (the default), some guide insist to change it to cgi.fix_pathinfo = 0 but doing that make PHP_SELF variable broken (not equal to DOCUMENT_URI)
