Download Mod_limitipconn.c tar.gz i386 rpm (Proxy client detection feature not enabled) source rpm

I'm using the tar package to download the mod_limitipconn-0.04.tar.gz, which is already available to support Apache2, to execute on the server

# wget http://dominia.org/djao/limit/mod_limitipconn-0.04.tar.gz Download to local

Then execute the following command to compile the installation. My Apache is in the/usr/local/apache directory

Decompression:

[Root@ns chenlf]# tar zxvf mod_limitipconn-0.04.tar.gz

To modify a configuration file:

1 Global control:

Add the following lines to the httpd.conf:

<ifmodule mod_limitipconn.c>
<location/> # All virtual Host/directory
Maxconnperip 3 # Only 3 concurrent connections per IP allowed
Noiplimit image/* # Don't make IP restrictions on pictures
</Location>

<Location/mp3> #/mp3 directory for all hosts
Maxconnperip 1 # Only one connection request per IP allowed
Onlyiplimit audio/mpeg Video # This limit is only for videos and audio format files
</Location>
</IfModule>

2 Local restrictions, you can also set the IP limit in the configuration file of the virtual host, the method is exactly the same:

<virtualhost xx.xxx.xx.xx>
ServerAdmin chenlf@chinalinuxpub.com
Documentroot/home/my
ServerName www.my.com
<ifmodule mod_limitipconn.c>
<location/> # All virtual Host/directory
Maxconnperip 5 # Only 3 concurrent connections per IP allowed
Noiplimit image/* # Don't make IP restrictions on pictures
</Location>
<Location/mp3> #/mp3 directory for all hosts
Maxconnperip 2 # Only one connection request per IP allowed
Onlyiplimit audio/mpeg Video # This limit is only for videos and audio format files
</Location>
</IfModule>
Errorlog/home/my/logs/error_log
Customlog/home/my/logs/access_log Common
</VirtualHost>

3 In addition, the Apache Extendedstatus must be set to on. Found in httpd.conf.
# Extendedstatus on

All right, all the configurations are over, and the Apache will be back in effect.
