Comment proxy Geoserver via Apache dans Windows

j'utilise un serveur web apache sur localhost: 80 et un géoserveur servi à partir de la jetée servlet sur localhost: 8888. Je veux configurer un proxy pour rediriger les demandes de telle sorte que les demandes vers localhost / geoserver soient acheminées vers localhost: 8888 / geoserver

je suis le tutoriel de http://gistutor.com/geoserver/21-intermediate-geoserver-tutorials/38-configuring-geoserver-proxy-for-public-and-remote-data-access.html et je suis coincé dans le partie où il est dit

copy the text below and right click to paste the ProxyPass into your httpd.conf file 
right above the </VirtualHost> tag.

ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /geoserver http://localhost:8080/geoserver
ProxyPassReverse /geoserver http://localhost:8080/geoserver

je ne trouve pas où insérer le texte ci-dessus dans le fichier httpd.conf. la directive des hôtes virtuels dans le fichier httpd.conf pointe vers le fichier httpd-vhosts.conf qui ressemble à ci-dessous

#
# Use name-based virtual hosting.
#
##NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
##<VirtualHost *:80>
##ServerAdmin postmaster@dummy-host.localhost
##DocumentRoot "C:/xampp/htdocs/dummy-host.localhost"
##ServerName dummy-host.localhost
##ServerAlias www.dummy-host.localhost
##ErrorLog "logs/dummy-host.localhost-error.log"
##CustomLog "logs/dummy-host.localhost-access.log" combined
##</VirtualHost>

##<VirtualHost *:80>
##ServerAdmin postmaster@dummy-host2.localhost
##DocumentRoot "C:/xampp/htdocs/dummy-host2.localhost"
##ServerName dummy-host2.localhost
##ServerAlias www.dummy-host2.localhost
##ErrorLog "logs/dummy-host2.localhost-error.log"
##CustomLog "logs/dummy-host2.localhost-access.log" combined
##</VirtualHost>

j'ai essayé et changé ce fichier httpd-vhosts.conf avec les codes ci-dessus, mais chaque fois que je le fais, je ne peux pas redémarrer le serveur apache.

c'est le fichier httpd.conf comme dans c: \ xampp \ apache \ conf \

#
# 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:/xampp/apache"

#
# 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.
#
#Listen 0.0.0.0:80
#Listen [::]:80
Listen 80

# '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. admin@your-domain.com
#
ServerAdmin postmaster@localhost

#
# 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.

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

# 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://localhost/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

Si vous utilisez Ubuntu, vous devrez d'abord configurer Apache

$sudo ln -s /etc/apache2/mods-available/proxy.conf /etc/apache2/mods-enabled/proxy.conf
$sudo ln -s /etc/apache2/mods-available/proxy.load /etc/apache2/mods-enabled/proxy.load
$sudo ln -s /etc/apache2/mods-available/proxy_http.load /etc/apache2/mods-enabled/proxy_http.load

Ajoutez ensuite ce qui suit à votre / etc / apache2 / sites-available / default

 ProxyRequests Off 
 # Remember to turn the next line off if you are proxying to a NameVirtualHost 
 ProxyPreserveHost On

 ProxyPassReverse /geoserver http://localhost:8888/geoserver

C'est un peu délicat sous Windows, vous devrez charger certains modules pour activer le proxy. Dans votre httpd.conf, ajoutez les éléments suivants:

LoadModule  proxy_module         modules/mod_proxy.so
LoadModule  proxy_http_module    modules/mod_proxy_http.so
#LoadModule proxy_ftp_module     modules/mod_proxy_ftp.so
#LoadModule proxy_connect_module modules/mod_proxy_connect.so
LoadModule  headers_module       modules/mod_headers.so
LoadModule  deflate_module       modules/mod_deflate.so
LoadModule  xml2enc_module       modules/mod_xml2enc.so
LoadModule  proxy_html_module    modules/mod_proxy_html.so

À la fin de votre httpd.conf, ajoutez les lignes suivantes

<VirtualHost  *:80>
   ProxyPass /geoserver http://localhost:8080/geoserver
   ProxyPassReverse /geoserver http://localhost:8080/geoserver
</VirtualHost>

Vous n'avez pas besoin de configurer proxypass et proxypassreverse.

Vous aurez besoin d'un fichier proxy.cgi écrit en python et python installé sur votre serveur. vous pouvez obtenir le fichier proxy avec la distribution openlayers dans le dossier d'exemple. vous devrez configurer le chemin d'accès à l'interpréteur python sur la 1ère ligne et ajouter votre hôte à la liste des hôtes autorisés.
