Agenda

Multiple Sites in OpenCms

3

● One OpenCms installation can be used to

maintain multiple websites

● Every site has its own set of resources and

can be addressed with an URL by the public

● Optional server aliases and a secure server

(https) can be configured for each site

● This information is stored in the OpenCms XML

configuration (opencms-system.xml)

4

Sites in OpenCms

● To add new or to manage existing sites

administrative server knowledge and

permissions were required

● Edit the OpenCms XML configuration

● Configure the Web-Server’s files manually

● Restart the servlet container

● The simple Site Manager’s UI helps to

decrease the configuration complexity

Web-Server Configuration

● OpenCms requires a specific Apache

configuration to

● Access a site with a nice web address

● Get rid of /opencms/opencms in the URL

● Serve static resources directly by Apache

● Configure the Web-Server is as well as editing

the OpenCms configuration a painstaking task

● Therefore OpenCms 9 supports generating

Web-Server configurations on-the-fly

8

Integrate Apache in front

● Prepare Apache Web-Server

● mod_proxy, mod_proxy_http, mod_rewrite and mod_jk

● Include a directory where for the virtual host files

● Create ONE virtual “by hand” for the OpenCms

workplace server

● Prepare Apache Tomcat

● Enable AJP connector and set session cookie path to

“/”, if OpenCms is not running as ROOT

● Prepare OpenCms (opencms-importexport.xml)

and replace the RFS and the VFS prefixes with

9

Environment preparation

<rfs-prefix>/export</rfs-prefix>

<vfs-prefix></vfs-prefix>

Virtual Host Template files

14

15

String Template based generation

<VirtualHost *:80>

DocumentRoot "$DOCUMENT_ROOT$"

ServerName $SERVER_NAME_WITH_PORT$

$ALIAS_DIRECTIVE$ $SERVER_ALIASES$

[...]

</VirtualHost>

● By default the distribution contains an Apache

virtual host “String template” that is working

with OpenCms out of the box …

16


$CONFIG_FILENAME$

$LOGGING_DIRECTORY$

$WEBAPP_NAME$

$DOCUMENT_ROOT$

$CONTEXT_PATH$

$SERVLET_PATH$

$DEFAULT_ENCODING$

$SERVER_URL$

$SERVER_NAME_WITH_PORT$

$SERVER_PROTOCOL$

$SERVER_NAME$

$SERVER_ALIASES$

$SECURE_URL$

$SECURE_SERVER_NAME$

$SECURE_SRV_WITH_PORT$

$SECURE_SERVER_PORT$

$SECURE_SERVER_PROTOCOL$

$ALIAS_DIRECTIVE$

$SITE_TITLE$

$ERROR_PAGE$

● Such a template file can contain „macros“, that

will be replaced when executing the „Update

Web-Server“ action

● Generated configuration files are written to a

specified location on the server's RFS

● As a very last step you can let the servlet

container execute a Shell-Script

17


cp ~Web-Server.tmp

/etc/apache2/sites-enabled/happy.managers.org

** only added for illustration purposes (something equivalent is done in Java) **

#!/bin/bash

# simple script reloading the apache web server

/etc/init.d/apache2 reload

● In a default OpenCms installation you'll find the

example files on the server at

<OPENCMS_HOME>/WEB-INF/server-scripts

18


available-macros.txt (with explanation in it)

script.bat (Restarts the Apache on Windows)

script.sh (reloads /etc/init.d/apache2 on Unix)

vhost.template (for none secure sites)

vhost-secure.template (for secure sites)

worker.conf (example for mod_jk)

worker.properties (ajp13 config)

Conclusion

19

● Administrators can now create new sites and

manage existing sites using a simple GUI

● Global settings like the workplace server, the

default URI or the shared folder location can be

selected using the new Admin-Tool

● Automated configuration update by OpenCms

● Generate Web-Server files 100% dynamically

… automatically run a script after generation

… and getting rid of /opencms/opencms/

… without deep knowledge about the Web-Server

● No servlet container restart required anymore
