Installation of OpenCms 6
This page provides information on how to install OpenCms using Tomcat and MySql. All
installation parts are described as single steps. After completing
each step you are strongly advised to verify the success.
1. Install the Java 2 SDK, version 1.4 or
newer
Install the Java 2 SDK, version 1.4 or newer (from SUN http://java.sun.com/products/j2se/ ).
For details on how to install these components on your operating
system, see the documentation that comes with them. You must
install the Java SDK, not the JRE (Java Runtime
Environment) that is also available from SUN. The JRE is not
sufficient to run OpenCms!
Important: This OpenCms 6 was tested with Java
1.4 and 1.5 only. Some features regarding file encoding where used
that are not available with Java releases before 1.4.
Please note: FreeBSD users may need to setup new
entropy sources in the O/S using rndcontrol . Otherwise the installation
process may hang. For example, on a machine with a network interface card on
IRQs 9, you can execute
rndcontrol -s 9
2. Install Tomcat
OpenCms 6.0 requires a Servlet 2.3 / JSP 1.2 standards compliant
container. Tomcat 4 is the reference implementation of this
Standard. This release was tested with Tomcat 4.1.x, Tomcat 5.0.x
and Tomcat 5.5.x. Older versions of Tomcat (3.x and earlier) do not
support this newer standard and are thus not usable for OpenCms
6.0. Tomcat 4.0.x was not tested, but may work.
Install Tomcat from http://jakarta.apache.org/tomcat/index.html
into a folder of your choice. This is the
CATALINA_HOME folder. Don't forget to set the
environment variables CATALINA_HOME and
JAVA_HOME .
Test the installation by running Tomcat in standalone mode and
check the examples. Note: Tomcat uses port 8080 in standalone mode.
If you wish, you can combine the servlet-engine with a webserver
like the Apache Web Server http://www.apache.org/httpd.html
. Please see the documentation available with the webserver on how
to combine it with your servlet environment.
Please note: There's an extended
OpenCms documentation module available from Alkacon Software GmbH
on the opencms.org website that describes how to setup OpenCms with
Apache httpd and Tomcat using mod_proxy.
Please note: On Linux systems, Tomcat's JVM has to be started with the command line argument
-Djava.awt.headless=true . The reason for this is that OpenCms uses Swing
classes for parsing RTF documents. Using these classes initializes
the GUI system. This leads to an exception as the server process doesn't
have access to the GUI system when not using the described argument.
Please note: Older OpenCms Version
required an environment setting for the Java file encoding
-dfile.encoding=.... for OpenCms. This is NOT longer
required with OpenCms 6.
3. Install MySQL
Install MySQL from http://www.mysql.com/downloads/index.html
(see the MySQL documentation on http://www.mysql.com/documentation/index.html
). On Windows-based systems MySQL has to be installed on the
C:\ drive and should be registered as service using
%MYSQL_HOME%/bin/mysqld -install .
OpenCms can be used with MySQL 3.2, 4.0 and 4.1. For performance
reasons we recommend MySQL 4.1, or at last 4.0.
Start the MySQL server by running the service (WIN32) or
executing %MYSQL_HOME%/bin/mysqld (UNIX).
Check that MySQL is running before you continue by starting the
MySQL monitor (execute mysql in your MySQL bin
folder). The database works correctly if a MySQL prompt appears
after calling the monitor. Quit the MySQL monitor by typing exit
and go to the next step.
Important: You will have to increase
the MySQL configuration variable max_allowed_packet located
in the MySQL configuration file (usually called my.ini ). For OpenCms,
the limit should be as high as possible, a setting of max_allowed_packet=16M is
recommended.
4. Deploy the opencms.war file
Copy the opencms.war file from the binary
distribution ZIP file to CATALINA_HOME/webapps/ .
Replace CATALINA_HOME with the real path to your
Tomcat installation.
Start (or restart) Tomcat. Tomcat will now deploy the web
application OpenCms.
Important: OpenCms requires that it's
*.war file is unpacked. OpenCms can not be deployed as
war file only. Make sure Tomcat does unpack the war file and
creates the CATALINA_HOME/webapps/opencms/ directory,
placing the OpenCms files in this directory. The default
configuration for your Servlet containers / environment could be to
not unpack the deployed *.war file. If this is so you
must unpack the opencms.war file manually. Use an unzip tool for
this, *.war files are just *.zip files
with a different extension. The OpenCms setup wizard will display a
warning and not allow you to continue if you did not unpack the
*.war file.
5. Install OpenCms using the Setup-Wizard
Start the Setup-Wizard by pointing your webbrowser to http://localhost:8080/opencms/setup .
Depending on your configuration, you have to replace
localhost with your servername. The port 8080 is only
used if you start Tomcat in standalone mode.
Follow the instructions of the OpenCms Setup-Wizard. It will set up the OpenCms database and
import all available modules into the system. For normal installations
with MySql and Tomcat running on the same server all default
settings will fit your needs.
If you are using different database users with MySql, be sure that they exist before creating the database tables and importing the modules.
Important: Make sure you disable all
popup blockers for the server URL you installed OpenCms on.
Otherwise you will not be able to log in to the OpenCms
Workplace.
6. Now your system is ready
Now your system is ready to use. You can login with username:
Admin and password: admin . Please change
this password as soon as possible. The login URL of OpenCms in a
default configuration is: http://localhost:8080/opencms/opencms/system/login/
7. Security issues
Finally after you have installed OpenCms you should have a look
at the security settings.
First change the Admin user password of OpenCms by
calling the user preferences (the "checkbox" icon on the main screen
of the Workplace).
Then you can add a password to the MySQL database. Enter the
following commands at the MySQL command line.
use mysql;
insert into user values ('localhost', 'opencmsuser', password('XXXXX'),\
'N','N','N','N','N','N','N','N','N','N','N','N','N','N');
insert into db values ('localhost', 'opencms', 'opencmsuser',\
'Y','Y','Y','Y','Y','Y','Y','Y','Y','Y');
flush privileges;
Make sure you replace opencmsuser and
opencms with the name of your user and database in
case you have changed them on the setup wizard.
Don't forget to add the new user and password to all connect
strings of the database in your opencms.properties
file. Only the new user can now connect to the OpenCms tables. For
more information see the MySQL documentation.
