nginx-mysql-module

(c) 2012 Arutyunyan Roman ([email protected])

== MySQL support in NGINX ==

* this module is asynchronous (non-blocking)
* requires nginx-mtask-module (https://github.com/arut/nginx-mtask-module)
* requires standard MySQL client shared library libmysqlclient.so


NGINX configure:

./configure --add-module=/home/rarutyunyan/nginx-mtask-module --add-module=/home/rarutyunyan/nginx-mysql-module


Usage examples:

MySQL:
	
	USE test;

	CREATE TABLE `users` (
			`name` varchar(128) DEFAULT NULL,
			`id` int(11) NOT NULL auto_increment,  PRIMARY KEY (`id`)
	) ENGINE=MyISAM DEFAULT CHARSET=utf8;


nginx.conf:

http {

	...

	server {

		...


		# TCP/IP access
		#mysql_host 127.0.0.1;

		# unix socket access (default)
		#mysql_host localhost;

		#mysql_user theuser;
		#mysql_password thepass;
		#mysql_port theport;

		mysql_database test;
		mysql_connections 32;

		mysql_charset utf8;

		# this turns on multiple statements support
		# and is REQUIRED when calling stored procedures
		mysql_multi on;

		mtask_stack 65536;


		location ~ /all {

			mysql_query "SELECT name FROM users WHERE id='$arg_id'";
		}

		location /multi {

			mysql_query "SELECT id, name FROM users ORDER BY id DESC LIMIT 10; SELECT id, name FROM users ORDER BY id ASC LIMIT 10";
		}

		location ~ /select.* {

			if ( $arg_id ~* ^\d+$ ) {

				mysql_query "SELECT name FROM users WHERE id='$arg_id'";

			}
		}

		location ~ /insert.* {

			mysql_escape $escaped_name $arg_name;

			mysql_query "INSERT INTO users(name) VALUES('$escaped_name')";
		}

		location ~ /update.* {

			mysql_query "UPDATE users SET name='$arg_name' WHERE id=$arg_id";
		}

		location ~ /delete.* {

			mysql_query "DELETE FROM users WHERE id=$arg_id";
		}

		# store number of page shows per user
		location ~ /register-by-cookie-show.* {

			# register show in database
			# need a location with this query:
			# mysql_query "INSERT INTO shows(id) VALUES('$id') ON DUPLICATE KEY UPDATE count=count+1";
			mysql_subrequest /update_shows_in_mysql?id=$cookie_abcdef;

			# output content
			rewrite ^(.*)$ /content last;
		}

		# spammers use big ids in picture refs to see who opened the message
		location ~/spammer-style-image-show-register.* {

			# need a location with this query:
			# mysql_query "INSERT INTO shows(id) VALUES('$arg_id')";
			mysql_subrequest /insert_show?id=$arg_id;

			rewrite ^(.*)$ /content last;
		}

		location ~ /session.* {

			# get user session
			# need a location with this query:
			# mysql_query "SELECT username, lastip FROM sessions WHERE id='$id'";
			mysql_subrequest /select_from_mysql?id=$cookie_abcdef $username $lastip;

			# go to content generator
			rewrite ^(.*)$ /content?username=$username&lastip=$lastip last;
		}
