Add mod_rewrite module to Apache

There is a new requirement recently:

 

Like Weibo addresses, the implementation of short addresses makes it easier to promote wireless advertisements;

 

Knowledge Point

1. Create a ing between a URL and a segment address, either in cache or in MySQL;

Create Table 'invalid url '(

'Id' mediumint (8) Not null auto_increment,

'Parm' char (30) not null default '', URL parameter

'Short 'char (10) Not null, short address

Primary Key ('id ')

) Engine = MyISAM default charset = utf8;

If a URL exists, it is read. If no URL exists, it is created;

Create a rule to generate a short address by ID;

2. How to generate a short address:

3, rewrite

The final short address access format is as follows:

Http: // domain/beedd

Then, you need to perform rewrite to jump to a file and then process it:

This can be done in the/redirect/index. php file;

I encountered some problems during rewrite: My testing environment is nginx test OK, but the online environment is Apache, And the rewrite module is not compiled. Depressed;

 

Add the rewrite module!

 

// InApacheFind the mod_rewrite.c file in the source code installation directory

# Find.-Name mod_rewrite.c

 

// Enter the directory containing the mod_rewrite.c File
# Cd modules/mappers/mod_rewrite.c

 

// Apxs should specify the absolute path, in which you are currently usingApacheIn the bin directory
 
#/Usr/local/Apache/bin/apxs-C mod_rewrite.c

#/Usr/local/Apache/bin/apxs-I-a-n mod_rewrite
Mod_rewrite.la

 
 
If there are no errorsApacheTo compile a mod_rewrite.so file.

 

 
Edit the httpd. conf file and confirm that the httpd. conf file contains the loading statement mod_rewrite.so,

As follows:
Loadmodule rewrite_module modules/mod_rewrite.so
 
At this time, yourApacheRewrite is supported.
 
Note: After this is done, remember to restart the server.Apache.
