Create a download-type WEB site with controllable bandwidth and threads

Article title: Create a download-type WEB site with controllable bandwidth and threads. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
　　 I. Preface
I wrote a typical configuration for a resource download website one afternoon based on my online materials and personal practices. This configuration allows WEB sites to manage IP thread and thread traffic, proftpd is used to upload resources, and ssh is used to manage hosts. Undoubtedly, this will allow you to control your valuable network bandwidth. a simple firewall configuration is provided later in this article for your reference. my linux version is redhat as 3.0. Hope you have read this article after a lot of exchanges with me, MAIL: LLZQQ@163.COM
　　
　　 II. software version
Apache-1.3.29
Mysql-4.0.16
Php-4.3.4
Proftpd-1.2.9
Mod_limitipconn-0.04
Mod_bandwidth-2.0.4
　　
　　 III. install and configure Mysql
# Cd mysql-4.0.16
　　
#./Configure -- prefix =/usr/local/mysql -- localstatedir =/usr/local/mysql/data
-- Disable-maintainer-mode? With-mysqld-user = mysql -- enable-large-files-without-debug
　　
# Make
# Make install
　　
Add a mysql User
　　
#/Usr/sbin/groupadd mysql
　　
Then we create a user called mysql which belongs to the mysql group;
　　
#/Usr/sbin/useradd-g mysql
　　
Install the database file:
　　
#./Scripts/mysql_install_db
　　
Set file permissions:
　　
# Chown-R root: mysql/usr/local/mysql
# Chown-R mysql: mysql/usr/local/mysql/data
　　
Configure ld. so. conf
　　
# Vi/etc/ld. so. conf
　　
Add the following sentence:
　　
/Usr/local/mysql/lib/mysql
　　
Create a mysql startup file:
　　
# Cp support-files/mysql. server/etc/init. d/mysql
# Cp support-files/my-medium.cnf/etc/my. cnf
　　
Start mysql in safe mode:
　　
#/Usr/local/mysql/bin/mysqld_safe? User = mysql &
　　
Set the mysql root password:
　　
#/Usr/local/mysql/bin/mysqladmin-u root password new_password
　　
Set the mysql service to start upon startup:
　　
# Chmod 755/etc/init. d/mysql
# Chkconfig? -Add mysql
# Chkconfig mysql on
　　
　　 4. install and configure PHP
# Cd php-4.3.4
　　
#./Configure -- prefix =/usr/local/php -- with-apxs =/usr/local/apache/bin/apxs -- with-mysql =/usr/local/mysql
　　
# Make
# Make install
　　
Create a php configuration file:
　　
# Cp php. ini-dist/usr/local/php/lib/php. ini
　　
Modify the php configuration file:
　　
# Vi/usr/local/php/lib/php. ini
　　
Doc_root = "/home/www /"
File_uploads = Off
Register-golbals = On
　　
Create a test php page
　　
# Vi/home/www/test. php
　　
　　
　　
# Chomd 755/home/www/test. php
　　
　　 5. install apache-1.3.29
# Tar zvxf apache_1.3.29.tar.gz
# Cd apache_1.3.29
# Cp ../mod_bandwidth.c
　　
Modify src/include/httpd. h to increase the maximum number of threads
# Vi src/include/httpd. h
　　
Modify
# Define HARD_SERVER_LIMIT 256
Is
# Define HARD_SERVER_LIMIT 2560
　　
#./Configure -- prefix =/usr/local/apache -- enable-module = so
-- Enable-module = rewrite -- enable-shared = max
-- Htdocsdir =/home/www -- add-module = mod_bandwidth.c
-- Permute-module = BEGIN: bandwidth
　　
# Make
# Make install
　　
Create a startup file:
　　
# Cp apachectl/etc/init. d/httpd
　　
Modify the apache configuration file:
　　
# Vi/usr/local/apache/conf/httpd. conf
　　
Modify, add, and confirm the following configuration items:
　　
Adddefacharcharset GB2312 comment out "addDefaultCharset ISO8859 *"
ExtendedStatus On
LoadModule php4_module modules/libphp4.so
DirectoryIndex index.html. var index. php
AddType application/x-httpd-php. php
AddType application/x-httpd-php-source. phps
LoadModule limitipconn_module libexec/mod_limitipconn.so
AddModule mod_limitipconn.c
　　
Install mod_limitipconn-0.04
　　
# Tar xzf mod_limitipconn-0.04.tar.gz
# Cd mod_limitipconn-0.04
# Vi Makefile
　　　
APXS =/usr/local/apache/bin/apxs
　　
# Make
# Make install
　　
To use the mod_limitip module, add this setting in httpd. conf.
　　
　　 　
　　 Set the directory to be controlled
MaxConnPerIP 2 limits the maximum number of threads per IP
　　　
　　
　　
Install the mod_bandwidth module
　　
Create a directory required to run mod_bandwidth
　　
Mkdir/var/apachebw
Mkdir/var/apachebw/link
Mkdir/var/apachebw/master
Chmod-R 777/var/apachebw
　　
Modify httpd. conf to add the following content:
　　
　　 　
BandWidthDataDir "/var/apachebw /"
BandWidthModule on
　　
　　 　
BandWidth 192.168.0 0 200000: the download speed of users in the Lan is 200 KB.
BandWidth all 51200 limits the download speed of other users to 51200 bytes per second
　　 　
　　
　　
　　
Modify/etc/init. d/httpd
　　
# Vi/etc/init. d/httpd
　　
Add the following content after three rows:
#! /Bin/sh
#
# Startup script for the Apache Web Server
# Chkconfig:-85 15
# Description: Apache is a World Wide Web server. It is used to serve \
# HTML files and CGI.
# Processname: httpd
# Pidfile:/usr/local/apache/log/httpd. pid

Set apache service to start at startup:
　　
# Chkconfig? -Add httpd
# Chmod 755/etc/init. d/httpd
# Chkconfig httpd on
　　
　　 6. install porftpd-1.2.9
# Tar? Zxvf proftpd-1.2.9.tar.gz
# Cd proftpd-1.2.9
#./Configure -- prefix =/usr/local/proftpd
# Make
# Make install
　　
Create a startup file and set proftpd to boot
　　
# Cp./contrib/dist/rpm/proftpd. init. d/etc/rc. d/init. d/proftpd
　　
　　
# Chkconfig -- add proftpd
# Chmod 755/etc/rc. d/init. d/proftpd
　　
# Vi/etc/rc. d/init. d/functions
Export PATH = "/sbin:/usr/sbin:/bin:/usr/X11R6/bin:/usr/local/proftpd/
Sbin"
　　
# Vi/etc/rc. d/init. d/proftpd
Config:/usr/local/proftpd/etc/proftpd. conf
PATH = "$ PATH:/usr/local/proftpd/sbin"
　　
# Chkconfig proftpd on
　　
Create an account and directory:
　　
# Mkdir/home/test
# Chmod 755/home/test
# Adduser-d/home/test-g ftp-s/sbin/nologin test
