Path mapping:-->/www/htdocs/download/bash-4.4.2-3.el6.x86_64.rpm

alias/url/"/path/to/somedir/"//url is the original path, followed by the alias Path//alias refers to the access to a path, the path should be under the DocumentRoot, but is directed to another location:

Example:

#mkdir-pv/www/htdocs

#cd!$

#mkdir BBS

#vim/www/htdocs/bbs/index.html//For the BBS directory to create a page to add content page At/bbs, at this time in the page is inaccessible

#vim/etc/httpd/conf.d/httpd.conf//Modify

alias/bbs/"/forum/htdocs"//define BBS alias as/forum/htdocs

Http://www.magedu.com/bbs/index.html

The alias path is:-->/forum/htdocs/bbs//forum created under the root directory, which is not related to DocumentRoot.

One , set the default character set

Adddefaultcharset UTF-8//Set default character set

GBK, GB2312, GB18030//These 3 are GB Chinese character code

A , user-based access control Important

1, certification questions:

Www-authenticate: The response code is 401, rejecting the client request and stating that the customer is required to provide the account number and password;

2, certification:

Authorization: The client user fills in the account number and the password again sends the request message, the authentication passes, then the server sends the response the resource;

Authentication type:

Basic: Clear Text authentication

Digest: Message digest (encrypted by MD5)

Security Domain : A path that requires user authentication to be accessible;

It should be identified by name and used to inform the user of the reason for authentication;

Where is the user's account and password stored?

Virtual Account: The authentication logo used only to access a service;

storage ://Virtual Account Storage Place

Add a virtual host based on IP

First step: Add the configuration in the main configuration file of httpd first

#vim/etc/httpd/conf/httpd.conf//Add a configuration file for two virtual hosts on the last line of the main configuration file

<virtualhost 192.168.108.160:80>

ServerName web1.magedu.com

DocumentRoot "/vhosts/web1/htdocs"

</VirtualHost>

<virtualhost 192.168.108.161:80>

ServerName web2.magedu.com

DocumentRoot "/vhosts/web2/htdocs"

</VirtualHost>

#httpd-T or #service httpd configtest//Can see if the master profile syntax is correct

Step Two:

#mkdir/VHOSTS/{WEB1,WEB2,WEB3,WEB4}/HTDOCS-PV//DocumentRoot to add a virtual host

Step Three: Configure the access page for the virtual host

#vim/vhosts/web1/htdocs/index.html added: Page at Web1

#vim/vhosts/web2/htdocs/index.html added: Page at WEB2
