Try OpenCms now. We explain where you can download the latest OpenCms version and how to install OpenCms locally. We will not cover an installation on a productive server. But you can develope your website locally and move to a server whenever you want. OpenCms makes it easy to move between different installations.
Why should I install OpenCms locally?
- You can log in to your local installation and play with it.
- OpenCms provides a feature-rich demo that you can explore and adapt.
- This documentation will ship with OpenCms and you can try the interactive demos in your local installation.
- It is not hard to move your generated content to other OpenCms installations, so you can use the local installation and start developing your own web site.
How to install OpenCms on your productive web server? - Look it up here.
1 Where to download OpenCms?
OpenCms is free. You can download the latest stable release at http://www.opencms.org/en/download/. Extract the downloaded file opencms.zip. It will contain a file opencms.war, that you need later on in the installation process.
2 What do I need to run OpenCms locally?
To use OpenCms you need
- a JDK (Java Developer Kit)
- a servlet container (e.g., Tomcat)
- a DBMS (e.g., MySql).
Here, you get a tutorial on how to install the JDK, MySql and Tomcat, and how to deploy and set up OpenCms. We recommend this installation, but of course you are free to choose other components to run OpenCms.
3.1 Install the Java SDK, version 6 or newer
Install the Java JDK, version 6 or newer (from Oracle http://www.oracle.com/technetwork/java/javase/downloads/index.html). For details on how to install these components on your operating system, see the documentation that comes with them. You must install the Java JDK (Java Development Kit), not the JRE (Java Runtime Environment) that is also available from Oracle. The JRE is not sufficient to run OpenCms!
3.2 Install Tomcat
OpenCms requires a Servlet 2.4 / JSP 2.0 standards compliant container. This release was tested with Tomcat 6.0.x. and Tomcat 7.0.x.
Install Tomcat from http://tomcat.apache.org 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://httpd.apache.org. Please see the documentation available with the webserver on how to combine it with your servlet environment.
-Djava.awt.headless=true.3.3 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 5.0, 5.1, 5.5 and 5.6.
Start the MySQL server by running the service (WINDOWS) 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.
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 at least max_allowed_packet=32M is recommended.
3.4 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.
*.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.3.5 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, be sure that they exist before creating the database tables and importing the modules.
3.6 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/.
3.7 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 in the top menu 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.
