1. --with-http_stub_status_module

This module shows the current client state of nginx

Configuration syntax: stub_status;

Default: no configuration

Arrangement positions: server, location below

Then restart nginx

Where: Active connections: represents the number of active connections currently nginx

server accepts handled requests: There are three values, a first value indicates the number of nginx handshake process, a second value represents the number of connections nginx process, the third value represents the total number of requests, and normal times for the number of connection handshake value should be equal, meaning no loss of connection

. --with-http_random_index_module

Select a directory index from the specified directory random, usually with more than Home diversification, giving the home feeling constantly changing.

Configuration syntax: random_index on | off;

Default value: off

Arrangement positions: location at

Case are as follows:

Create a directory / opt created before now 2.1 / app / next directory code, written in html inside three, three html inside as long as you can set the background color, as follows

Default.conf 2.2 configuration file, modify the following two places

2.3 Test

Reload nginx service, use the command service nginx reload;

Enter in your browser ip, you can see the page appear different background color, refresh a few times, to see the results, note that in the random directory configuration, if you write a hidden file, such as .4.html file, such hidden files will not be random to, you are interested, you can test.

Configuration syntax: sub_filter string (text to replace it) string (text to be used)

Default Configuration: no configuration

Configuration Location: http, server, location under

The first actual configuration demo

3.1 sub_filter.html a new file in the code directory, as follows
