Nginx Proxy Module

Wind Network (ithov.com) original article: Nginx by the kernel and modules, in which the design of the kernel is very small and concise, the completion of the work is very simple, only through the lookup configuration file to map client requests to a location Block (location is an instruction in the Nginx configuration for URL matching), and each instruction configured in this location will start a different module to do the work accordingly. The Nginx module is divided into Core module, basic module and third party model.

Nginx modules must be specified at compile time, complete compilation options, available modules can refer to installation options below is an example:./configure \--prefix=/usr \--sbin-path=/usr/sbin/nginx \ conf-path=/etc/nginx/nginx.conf \--error-log-path=/var/log/nginx/error.log \--pid-pat ...

Nginx can proxy IMAP, POP3, and SMTP protocols. directive Proxy syntax: Proxy on | Off default: Off use field: Mail, server settings whether mail agent is enabled. Proxy_buffer syntax: Proxy_buffer size default: 4k/8k using fields: Mail, Server sets the buffer size for the proxy connection, defaults to paging size, and may be 4k or 8k depending on the operating system. P ...

If you want to use these modules, you must specify the relevant compilation parameters at compile time. This module allows you to modify the IP address of the client in the request header (such as X-real-ip and X-forwarded-for). This is useful for some nginx that work on the back of the seven-layer http://www.aliyun.com/zixun/aggregation/13996.html "> Load balancer, requests from local IP, But the proxy server in the request header added the client's true IP ...

These modules are all compiled into Nginx by default unless a module is manually specified to be excluded in configure. This module creates variables whose values are dependent on the IP address of the client: Geo $geo {default 0; 127.0.0.1/32 2; 192.168.1.0/24 1; 10.1.0.0/16 1;} directive GEO syntax: Geo [$IP _ Variable] $variable {...} default value: None ...

These modules are all compiled into Nginx by default unless a module is manually specified to be excluded in configure. This module adds a character encoding to the Content-type field in the answer header. In addition, this module can encode the data and can only be encoded in one way, that is, from the server to the client. Configuration instance: CharSet Windows-1251;source_charset koi8-r; Instruction CharSet syntax: CharSet Encodi ...

Translator: Alfredcheung on the topic of building high throughput Web applications, Nginx and Node.js are natural couples. They are all based on the event-driven model and are designed to easily break through the c10k bottlenecks of traditional Web servers such as Apache. Preset configurations can be highly concurrent, but there is still work to do if you want to do more than thousands of requests per second on inexpensive hardware. This article assumes that readers use Nginx's httpproxymodule for upstream node ....

Nginx itself does not own PHP processing module, so need to configure the reverse proxy, the PHP request to the other PHP parser execution, and then return the results to Nginx. The current fashion is to configure the PHP processing service in a fast-cgi way. The advantages are relatively simple, the server load is light. But the downside is obvious: the PHP processing state cannot be viewed. such as 8630.html "> sometimes the site because the load is too high, the PHP processing thread has been all blocked, will cause the Web site can no longer respond to the PHP service ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

Overview WEB attack is the mainstream technology of hacker attacks for more than a decade. The domestic manufacturers have long regarded WAF as the standard of security infrastructure. There are many security vendors in the market that offer WAF products or cloud WAF services. For the lack of their own security team, but also suffer from sql injection, xss, cc and other WEB attacks in the small and medium enterprises, the demand for WAF is also very urgent. WAF access to the current are the following: WAF products to buy security vendors using the cloud waf service, the domain name of the DNS server is set to cloud waf manufacturers to provide, or ...
