apache 2.2 到 apache 2.2 代理

通过apache 2.2作为在另外两台apache服务器的入口，提供访问入口配置

 

修改httpd.conf

如下

#

# This is the main Apache HTTP server configuration file.  It contains the

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.2/> for detailed information.

# In particular, see 

# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>

# for a discussion of each configuration directive.

#

# Do NOT simply read the instructions in here without understanding

# what they do.  They're here only as hints or reminders.  If you are unsure

# consult the online docs. You have been warned.  

#

# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# server will use that explicit path.  If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"

# with ServerRoot set to "C:/Program Files/Apache Software Foundation/Apache2.2" will be interpreted by the

# server as "C:/Program Files/Apache Software Foundation/Apache2.2/logs/foo.log".

#

# NOTE: Where filenames are specified, you must use forward slashes

# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").

# If a drive letter is omitted, the drive on which Apache.exe is located

# will be used by default.  It is recommended that you always supply

# an explicit drive letter in absolute paths, however, to avoid

# confusion.

#

 

# ThreadsPerChild: constant number of worker threads in the server process

# MaxRequestsPerChild: maximum  number of requests a server process serves

ThreadsPerChild 1000

MaxRequestsPerChild  10000

 

#

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# Do not add a slash at the end of the directory path.  If you point

# ServerRoot at a non-local disk, be sure to point the LockFile directive

# at a local disk.  If you wish to share the same ServerRoot for multiple

# httpd daemons, you will need to change at least LockFile and PidFile.

#

ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2"

 

#

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the <VirtualHost>

# directive.

#

# Change this to Listen on specific IP addresses as shown below to 

# prevent Apache from glomming onto all bound IP addresses (0.0.0.0)

#

#Listen 12.34.56.78:80

Listen 80

 

#

# Dynamic Shared Object (DSO) Support

#

# To be able to use the functionality of a module which was built as a DSO you

# have to place corresponding `LoadModule' lines at this location so the

# directives contained in it are actually available _before_ they are used.

# Statically compiled modules (those listed by `httpd -l') do not need

# to be loaded here.

# 'Main' server configuration

#

# The directives in this section set up the values used by the 'main'

# server, which responds to any requests that aren't handled by a

# <VirtualHost> definition.  These values also provide defaults for

# any <VirtualHost> containers you may define later in the file.

#

# All of these directives may appear inside <VirtualHost> containers,

# in which case these default settings will be overridden for the

# virtual host being defined.

#

 

#

# ServerAdmin: Your address, where problems with the server should be

# e-mailed.  This address appears on some server-generated pages, such

# as error documents.  e.g. [e-mail]

#

ServerAdmin [e-mail]

 

#

# ServerName gives the name and port that the server uses to identify itself.

# This can often be determined automatically, but we recommend you specify

# it explicitly to prevent problems during startup.

#

# If your host doesn't have a registered DNS name, enter its IP address here.

#

ServerName www.szhtkj.net:80

 

#

# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory, but

# symbolic links and aliases may be used to point to other locations.

#

DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs"

 

#

# Each directory to which Apache has access can be configured with respect

# to which services and features are allowed and/or disabled in that

# directory (and its subdirectories). 

#

# First, we configure the "default" to be a very restrictive set of 

# features.

# you might expect, make sure that you have specifically enabled it

# below.

#

# This should be changed to whatever you set DocumentRoot to.

#

    # Note that "MultiViews" must be named *explicitly* --- "Options All"

    # doesn't give it to you.

    #

# ErrorLog: The location of the error log file.

# If you do not specify an ErrorLog directive within a <VirtualHost>

    #CustomLog logs/access.log combined

</IfModule>

 

<IfModule alias_module>

    #

    # Redirect: Allows you to tell clients about documents that used to 

    # exist in your server's namespace, but do not anymore. The client 

    # will make a new request for the document at its new location.

    # Example:

    # Redirect permanent /foo http://www.szhtkj.net/bar

 

    #

    # Alias: Maps web paths into filesystem paths and is used to

    # access content that does not live under the DocumentRoot.

    # Example:

    # Alias /webpath /full/filesystem/path

    #

    # If you include a trailing / on /webpath then the server will

    # require it to be present in the URL.  You will also likely

    # need to provide a <Directory> section to allow access to

    # the filesystem path.

 

    #

    # ScriptAlias: This controls which directories contain server scripts. 

    # ScriptAliases are essentially the same as Aliases, except that

    # documents in the target directory are treated as applications and

    # run by the server when requested rather than as documents sent to the

    # client.  The same rules about trailing "/" apply to ScriptAlias

    # directives as to Alias.

    #

    ScriptAlias /cgi-bin/ "C:/Program Files/Apache Software Foundation/Apache2.2/cgi-bin/"

 

</IfModule>

 

#

# 

# Apache parses all CGI scripts for the shebang line by default.

# This comment line, the first line of the script, consists of the symbols

# pound (#) and exclamation (!) followed by the path of the program that 

# can execute this specific script.  For a perl script, with perl.exe in

# the C:\Program Files\Perl directory, the shebang line should be:

 

   #!c:/program files/perl/perl

 

# Note you _must_not_ indent the actual shebang line, and it must be the

# first line of the file.  Of course, CGI processing must be enabled by 

# the appropriate ScriptAlias or Options ExecCGI directives for the files 

# or directory in question.

#

# However, Apache on Windows allows either the Unix behavior above, or can

# use the Registry to match files by extention.  The command to execute 

# a file of this type is retrieved from the registry by the same method as 

# the Windows Explorer would use to handle double-clicking on a file.

# These script actions can be configured from the Windows Explorer View menu, 

# 'Folder Options', and reviewing the 'File Types' tab.  Clicking the Edit

# button allows you to modify the Actions, of which Apache 1.3 attempts to

# perform the 'Open' Action, and failing that it will try the shebang line.

# This behavior is subject to change in Apache release 2.0.

#

# Each mechanism has it's own specific security weaknesses, from the means

# to run a program you didn't intend the website owner to invoke, and the

# best method is a matter of great debate.

#

# To enable the this Windows specific behavior (and therefore -disable- the

# equivilant Unix behavior), uncomment the following directive:

#

#ScriptInterpreterSource registry

#

# The directive above can be placed in individual <Directory> blocks or the

# .htaccess file, with either the 'registry' (Windows behavior) or 'script' 

# (Unix behavior) option, and will override this server default option.

#

 

#

# DefaultType: the default MIME type the server will use for a document

# if it cannot otherwise determine one, such as from filename extensions.

# If your server contains mostly text or HTML documents, "text/plain" is

# a good value.  If most of your content is binary, such as applications

# or images, you may want to use "application/octet-stream" instead to

# keep browsers from trying to display binary files as though they are

# text.

#

DefaultType text/plain

 

<IfModule mime_module>

    #

    # TypesConfig points to the file containing the list of mappings from

    # filename extension to MIME-type.

    #

    TypesConfig conf/mime.types

    # AddType allows you to add to or override the MIME configuration

    # file specified in TypesConfig for specific file types.

    #AddEncoding x-compress .Z

    #AddEncoding x-gzip .gz .tgz

    #

    # If the AddEncoding directives above are commented-out, then you

    # probably should define those extensions to indicate media types:

    #

    AddType application/x-compress .Z

    AddType application/x-gzip .gz .tgz

 

    #

    # AddHandler allows you to map certain file extensions to "handlers":

    # actions unrelated to filetype. These can be either built into the server

    # or added with the Action directive (see below)

    #

    # To use CGI scripts outside of ScriptAliased directories:

    # (You will also need to add "ExecCGI" to the "Options" directive.)

    #

    #AddHandler cgi-script .cgi

 

    # For type maps (negotiated resources):

    #AddHandler type-map var

 

    #

    # Filters allow you to process content before it is sent to the client.

    #

    # To parse .shtml files for server-side includes (SSI):

    # (You will also need to add "Includes" to the "Options" directive.)

    #

    #AddType text/html .shtml

    #AddOutputFilter INCLUDES .shtml

</IfModule>
