Dynamic configuration of large-capacity Virtual Hosts

Method 1: Simple Dynamic Virtual Host code: This is the configuration method of the virtual host in the httpd. conf file. mod_vhost_alias is used here. # Obtain the server name ServerNameUseCanonicalNameOff from the Host: Header # The log format here can be separated by the first parameter field in the future

Method 1: Simple Dynamic Virtual Host code: This is the configuration method of the virtual host in the httpd. conf file. mod_vhost_alias is used here. # Obtain the Server Name "Server Name UseCanonicalName Off" from the Host: Header # The log format here can be separated by the first parameter field in the future

Method 1: simple Dynamic Virtual Host

Code:

This is in the httpd. conf file. Virtual HostOf ConfigurationMod_vhost_alias is used here.

# Obtain the Server Name from Host: Header Server Name

UseCanonicalName Off

# The log format here can be separated by the first parameter field in the future Virtual HostLogs

LogFormat "% V % h % l % u % t" % r "% s % B" vcommon

CustomLog logs/access_log vcommon

# Include the server name in the path of the returned request file name

VirtualDocumentRoot/ Virtual HostSpace root directory/% 0/htdocs

VirtualScriptAlias/ Virtual HostSpace root directory/% 0/cgi-bin

# Create/% 0/htdocs first, and put the file in htdocs for access

# % 0 Virtual HostFor example, www.net.cn.

Disable UseCanonicalName ConfigurationChange to UseCanonicalName DNS to implement IP address-based Virtual Host. The server name to be inserted in the file path is Virtual Host.

Method 2: Multiple Dynamic Virtual Host

Code:

UseCanonicalName Off

LogFormat "% V % h % l % u % t" % r "% s % B" vcommon



Options FollowSymLinks

AllowOverride All





Options FollowSymLinks

AllowOverride None





ServerName www.commercial.isp.com

CustomLog logs/access_log.commercial vcommon

VirtualDocumentRoot/www/commercial/% 0/docs

VirtualScriptAlias/www/commercial/% 0/cgi-bin





ServerName www.homepages.isp.com

CustomLog logs/access_log.homepages vcommon

VirtualDocumentRoot/ Virtual HostSpace root directory/% 0/htdocs

VirtualScriptAlias/ Virtual HostSpace root directory/% 0/cgi-bin



Method 3: IP address-based Virtual Host

Code:

# Obtain the server name from IP address reverse resolution)

UseCanonicalName DNS

# Include IP addresses in logs to facilitate subsequent distribution

LogFormat "% A % h % l % u % t" % r "% s % B" vcommon

CustomLog logs/access_log vcommon

# Include IP address % 0 in the file path to indicate IP Address

VirtualDocumentRootIP/www/hosts/% 0/docs

VirtualScriptAliasIP/www/hosts/% 0/cgi-bin



Method 4: Use mod_rewrite Virtual HostSystem

Code:

RewriteEngine on

RewriteMap lowercase int: tolower

# Check whether the hostname is correct before RewriteRule can take effect

RewriteCond $ {lowercase: % {SERVER_NAME} ^ www \. [a-z-] + \. isp \. com $

# Set Virtual HostThe name must start with URI.

# [C] indicates that the result of this rewrite will be used in the next rewrite rule

RewriteRule ^ (. +) $ {lowercase: % {SERVER_NAME }}$ 1 [C]

# Create the actual file name

RewriteRule ^ www \. ([a-z-] +) \. isp \. com/(. *)/home/$1/$2



Highlights

Method 5: Use an independent Virtual Host ConfigurationFile

When you modify vhost. map, you do not need to restart Apache.

Code:

This layout utilizes the advanced features of mod_rewrite Virtual Host ConfigurationFile conversion. This can be more flexible, but requires more complex settings.

The vhost. map file contains content similar to the following:

Www.customer-1.com/www/Mers MERs/1

Www.customer-2.com/www/Mers MERs/2

#......

Www.customer-N.com/www.mers MERs/N

Http. conf includes:

RewriteEngine on

RewriteMap lowercase int: tolower

# Defining image files

RewriteMap vhost txt:/VHOST. map path/vhost. map

# Process name change as in the preceding example

RewriteCond % {REQUEST_URI }! ^/Icons/

RewriteCond % {REQUEST_URI }! ^/Cgi-bin/

RewriteCond $ {lowercase: % {SERVER_NAME} ^ (. +) $

# File-based re ing

RewriteCond $ {vhost: % 1} ^ (/. *) $

RewriteRule ^/(. *) $ % 1/docs/$1

RewriteCond % {REQUEST_URI} ^/cgi-bin/

RewriteCond $ {lowercase: % {SERVER_NAME} ^ (. +) $

RewriteCond $ {vhost: % 1} ^ (/. *) $

RewriteRule ^/(. *) $ % 1/cgi-bin/$1

If you go to http://w.yi.org, use keywords Virtual HostSearch all at once, I believe there will be more information
