Як проксі-сервер Geoserver через Apache в Windows

Я використовую веб-сервер apache на localhost: 80 та геосервер, що обслуговується з сервісу jetty на localhost: 8888. я хочу встановити проксі-сервер для переадресації запитів таким чином, щоб запити на localhost / geoserver перенаправлялися на localhost: 8888 / geoserver

я слідкую за підручником від http://gistutor.com/geoserver/21-intermediate-geoserver-tutorials/38-configuring-geoserver-proxy-for-public-and-remote-data-access.html, і я застряг у частина, де сказано

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

я не можу знайти, куди слід вставити текст вище у файл httpd.conf. директива щодо віртуальних хостів у файлі httpd.conf вказує на файл httpd-vhosts.conf, який виглядає нижче

#
# 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>

Я спробував і змінив цей файл httpd-vhosts.conf з вищезазначеними кодами, але кожен раз, коли я це роблю, я не можу перезапустити сервер apache.

це файл httpd.conf, як у 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>

Якщо ви використовуєте Ubuntu, спочатку доведеться налаштувати 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

Потім додайте наступне до вашого / etc / apache2 / sites-available / default

У Windows це досить складно, вам доведеться завантажити деякі модулі, щоб увімкнути проксі. У свій httpd.conf додайте наступне:

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  xml2enc_module       modules/mod_xml2enc.so
LoadModule  proxy_html_module    modules/mod_proxy_html.so

В кінці свого httpd.conf додайте наступні рядки

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

Вам не потрібно налаштовувати proxypass і proxypassreverse.

Вам знадобиться файл proxy.cgi, записаний в python, і python, встановлений на вашому сервері. ви можете отримати проксі-файл із розподілом openlayers у папці з прикладом. вам доведеться налаштувати шлях до інтерпретатора python у 1-му рядку та додати хоста до списку дозволених хостів.
