The Apache Rewrite URL redirection feature simple configuration _linux

Main functions of 1.Apache rewrite
is to implement the URL of the jump and hide the real address, based on the Perl language regular expression specification. Usually help us achieve quasi static, quasi-directory, domain name jump, prevent hotlinking, etc.

configuration of 2.Apache rewrite
Apache rewrite configuration has two main, one is for the entire Apache server configuration, the rewrite rules of this configuration is directly written under httpd.conf. The configuration steps are as follows:
(1) Remove the "#" number in front of "#LoadModule rewrite_module modules/mod_rewrite.so" in the httpd.conf file;
(2) and then write the following rules in httpd.conf:
Rewriteengine on
#当访问任何以t_开头, when a file ending with. html is replaced with a character that matches (. *), the corresponding test.php page is accessed
Rewriterule ^/t_ (. *). html$/test.php?id=$1

The other is for the configuration of a directory under the Apache server, and the rewrite rules for this configuration need to be set up in this directory to write a. htaccess file. The configuration steps are as follows:
(1) Remove the "#" number in front of "#LoadModule rewrite_module modules/mod_rewrite.so" in the httpd.conf file;
(2) Modify the "AllowOverride None" in the httpd.conf file as "allowoverride all", at the same time, it is best to make the options also "all", otherwise there may be problems.
(3) Create a. htaccess file in the directory and open it with Notepad to write the following rules:
Rewriteengine on
Rewriterule ^/t_ (. *). html$/test.php?id=$1

the writing of 3.Apache rewrite rules
Rewriteengine on
Rewriterule ^/test ([0-9]*). html$/test.php?id=$1
Rewriterule ^/new ([0-9]*)/$/new.php?id=$1 [R]

Rewriteengine on
#当我们访问的地址不是以www. 163.com, then execute the next rule
Rewritecond%{http_host}!^www.163.com [NC]
Rewriterule ^/(. *) http://www.163.com/[L]
