This article is about how to use Nginx+Lua for Web development. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Nginx ("engine x") is a high-performance HTTP and reverse proxy server, as well as an IMAP/POP3/SMTP server. It is known for its stability, rich feature set, sample configuration files, and low consumption of system resources. Lua is written by standard C and can be compiled and run on almost all operating systems and platforms. A complete Lua interpreter is only 200k, and Lua is the fastest of all script engines. The combination of the two can develop high-performance Web applications.

Using Nginx+Lua for Web Development

Openresty combines nginx and lua. OpenResty is a high-performance Web platform based on Nginx and Lua, which integrates a large number of excellent Lua libraries, third-party modules and most dependencies. It is used to conveniently build dynamic Web applications, Web services and dynamic gateways that can handle ultra-high concurrency and high scalability.

OpenResty effectively turns Nginx into a powerful general-purpose Web application platform by bringing together a variety of well-designed Nginx modules (mainly developed by the OpenResty team). In this way, Web developers and system engineers can use Lua scripting language to mobilize various C and Lua modules supported by Nginx to quickly build a high-performance Web application system capable of concurrent connections on a single machine of 10K or more than 1000K.

The goal of OpenResty is to have your Web service run directly inside the Nginx service, taking full advantage of Nginx's non-blocking IPUP O model to provide consistent, high-performance responses not only to HTTP client requests, but even to remote backends such as MySQL, PostgreSQL, Memcached, and Redis.

1. Install openresty

Under Ubuntu:

Sudo apt-get install openresty

Under Mac:

Brew install homebrew/nginx/openresty

two。 Configure nginx.conf

Add a server configuration to openresty

Lua_package_path'/ Users/M/workspace/lua/tuyang-lua/?.lua;;'

Server {

Listen 80

Server_name lua.tuyang.dev

Charset utf8

# access_log logs/host.access.log main

Root / Users/M/workspace/lua/tuyang-lua

Location / {

Index index.html index.htm index.php

}

Location ~ ^ / app/ ([- _ 0-9a-zA-Z] +) {

Lua_code_cache off

Default_type 'text/plain'

Content_by_lua_file $document_root/$1.lua

}

}

Lua_package_path sets the search path of lua script, which is equivalent to classPath in Java

Location ~ ^ / app/ all url requests in the / app path will be intercepted and responded to by the location

Lua_code_cache off closes the lua script cache so that during development, after modifying the lua script, you can see the modified results without restarting the server.

Content_by_lua_file finds the lua script that executes

The server root directory defined by $document_root, which is now / Users/M/workspace/lua/tuyang-lua

3. Restart the openresty server

Sudo openresty-s reload

4.helloWorld tutorial

Create a file under the server root directory you just configured and name it index.lua

Ngx.say ('

Hello world!

')

5. Access using a browser
