Environment for running RIB v3.0
RIB v3.0 will be running as a web application, so an environment for running web
applications is necessary to run RIB. A typical environment RIB runs on requires
the following components: Java JDK, Tomcat web container
and MySQL database system. You will also need the Java Runtime Environment (JRE)
on any machine that will be running the Java administration Applet. This is not necessarily
the same machine that is running RIB. Instructions on how to install these various
components are given below, as well as instructions on installing RIB itself. If
one or more of these components have already been installed on your system, you
can skip the corresponding sections on installing them; if your system has all
components installed already, you can go directly to the section on
installing RIB v3.0. RIB v3.0 runs on both the Unix and the Windows platforms,
so the installation instructions below will be based on these two types of platforms.
RIB v3.0 requires JDK 1.4.0 or above. JDK's and JRE's can be downloaded from
Sun's website for free.
Installation instructions are available from the same page
that you download your package from. These instructions will be specific for
the platform and version that you have selected. For your conveniences,
links are provided here for downloading and documentation.
It is recommended that you use the latest version of JDK available.
(Note: RPM packages will require root privileges to install.)
(Let JDK_DIR denote the installation directory of your JDK)
On Unix, you will need to set the environment variable JAVA_HOME. Depending on your shell either one
of these commands should work. This step needs to be done prior to starting Tomcat. This can also be
placed in your shell resource file to be set automatically when you login ( e.g. .cshrc ).
tcsh: setenv JAVA_HOME JDK_DIR
bash: JAVA_HOME=JDK_DIR; export JAVA_HOME
You may also want to add the path to the "Java" command to your PATH environment variable
in a similar way.
On Windows, if you will be using your JDK with Tomcat 4.x, you may need to create the JAVA_HOME
environment variable. You can do this by going to "Start -> Settings -> Control Panel -> System
-> Advanced -> Environment Variables", creating a new variable JAVA_HOME and pointing it to
JDK_DIR. (Setting the JAVA_HOME environment variable is not required by Tomcat 5.x)
You can also add the path to the "Java" command to your PATH environment variable
the same way as described above.
RIB v3.0 requires Tomcat 4.1 or above. Tomcat can be downloaded from the
Apache Jakarta Project website for free and instructions on installation can also be found there.
For your convenience, links are provided here for downloading
and documentation. It is recommended that you use the latest version of Tomcat available.
(Let TOMCAT_DIR denote the installation directory of your Tomcat)
On Unix, you can start/stop Tomcat with the commands below:
./startup.sh (to start)
./shutdown.sh (to stop)
On Windows, if you are using Tomcat 4.x, you can start/stop it by going to TOMCAT_DIR/bin
and invoking "startup.bat" to start and "shutdown.bat" to stop.
When using Tomcat 5.x, you can start/stop it by going to "Start -> Programs -> Apache Tomcat 5.x
-> Configure Tomcat".
To verify that Tomcat is properly installed and working, open a browser to http://localhost:8080,
you should be able to see the Tomcat startup page.
RIB v3.0 requires MySQL 4.0 or above. MySQL can be downloaded from the
MySQL website for free
and the installation guide can be found there too. For your conveniences,
links are provided here for downloading and documentation. It is recommended
that you use the latest version of MySQL available.
(Let MYSQL_DIR denote the installation directory of your MySQL)
The documentation describes several ways to install MySQL directed to a user with
root privileges. If you do not have root, you should download a source tarball and
not an RPM or binary release. These will need write access
to /usr/local, you can use --prefix to install the source tarball
into your home area. To install MySQL with non-privileged user account you can follow
the steps outlined below.
||Download from here:
||tar zxvf mysql-4.x.x.tar.gz
(this is the path designated with --prefix above, in the var directory)
(this is the path designated with --prefix above)
||bin/mysqladmin -u root password 'new-passwd'
|(Note: You will need to replace versions and paths to match your version and environment)
On Unix, you can invoke the MySQL command line client
with the commands below:
./mysql --user=username --password=password
On Windows, if you are using MySQL 4.0, you can invoke the MySQL command line client
with the commands below:
.mysql --user=username --password=password
When using MySQL 4.1, in addition to invoking the MySQL command line client the same way
as described above, you can also invoke it by going to "Start -> Programs -> MySQL ->
MySQL Server 4.1 -> MySQL Command Line Client".
You also need to get a copy of the JDBC driver for MySQL in order for RIB to access your database
through Java. The official JDBC driver for MySQL database is MySQL Connector/J, as provided by MySQL.
You can download it through the following link:
Download MySQL Connector/J
Important: Please copy the .jar file to JAVA_HOME/jre/lib/ext
(also to JRE_DIR/lib/ext if you have the JRE installed),
since this is the place where the JDBC driver can be found automatically by the
Java Virtual Machine (JVM). Otherwise you might receive error messages like
"java.lang.ClassNotFoundException: com.mysql.jdbc.Driver" when running RIB. If you see the above ClassNotFoundException you should try placing the JDBC driver in the TOMCAT/webapps/rib3app/WEB-INF/lib directory.
Creating the "rib3" database and the "rib3" user account
After installing MySQL, you need to create a database named "rib3" for the RIB web application.
Also, it is highly recommended that you remove the anonymous accounts and create a user account "rib3".
You should use the "rib3" account to access your database instead of using the "root" account
for security reasons. You can perform the above tasks with the commands below:
(All commands are to be executed by the MySQL command line client.)
(Invoke the MySQL command line client, login as "root")
||Create "rib3" database:
mysql> CREATE DATABASE rib3;
||Remove anonymous accounts:
mysql> DELETE FROM mysql.user WHERE User = '';
||Create "rib3" user account:
mysql> GRANT ALL PRIVILEGES ON rib3.* TO rib3@localhost IDENTIFIED BY 'yourpassword';
mysql> FLUSH PRIVILEGES;
Installing RIB v3.0
Before proceeding to install RIB v3.0 on your system, please make sure the
following things have been done:
- Java has been installed and functions properly (if not, please go back to Installing Java)
- Tomcat has been installed and functions properly (if not, please go back to Installing Tomcat)
- MySQL has been installed and functions properly (if not, please go back to Installing MySQL)
- JDBC driver has been installed and a database named "rib3" has been created (if not, please go back to Installing MySQL)
Once all components required by RIB v3.0 have been properly installed and can function properly,
installing the RIB web application becomes a very easy task. RIB v3.0 (beta) can be obtained from the Software page.
After downloading, unpack the compressed file under the root directory of all your web applications
to create a new web application "rib3app".
(Let TOMCAT_DIR denote the installation directory of your Tomcat)
Unpack rib3app.tgz under TOMCAT_DIR/webapps to create TOMCAT_DIR/webapps/rib3app
using the command: "gunzip -dc rib3app.tgz | tar -xvf -".
Unzip rib3app.zip under TOMCAT_DIR\webapps to create TOMCAT_DIR\webapps\rib3app
using a third party software like WinZip.
When unpacking is done, you need to configure your RIB v3.0 installation following the steps below:
- Make sure your MySQL database server is running
- Start your Tomcat web server
- Open a browser window
- Type in the URL ROOT_URL/rib3app/config to launch the web-based configuration interface
(ROOT_URL here denotes the root URL of all your web applications)
The web-based configuration interface will collect various information about your
Java JDK, RIB 3.0 web application, MySQL database system and etc. Default values will be provided,
and you need to make sure that they match your actual settings and make changes when necessary.
All collected information will be saved to your "RIBSettings.ini" file under
TOMCAT_DIR/webapps/rib3app/WEB-INF/classes/edu/utk/cs/rib. You can always go directly to this
file and edit it manually to make further changes. See here for a sample "RIBSettings.ini" file and explanations to various entries in the file.
If no problem occurs when configuration is done, you need to restart your Tomcat web server
to accommodate changes made during configuration, and then you should be able to run
RIB v3.0 as a standard web application. The main RIB password to access the RIB
administrator's management page is the password you provided in the "Administration Configuration" section.
Setting up auto-update for interoperations
In order for RIB to be able to automatically perform updates, you must have set up a
scheduled job on the machine where RIB is installed. On Unix machines this is done
using the "cron" system utility. Assuming that the RIB web application is installed
in the directory /usr/local/jakarta-tomcat-5.5.4/webapps/rib3app, simply add a line
such as the following to a crontab:
0,15,30,45 * * * * java -cp /usr/local/jakarta-tomcat-5.5.4/webapps/rib3app/bin:
(Note: The "-cp CLASSPATH" parameter can not be omitted as "UpdateAllInterops" uses packages
that can only be found under the specified CLASSPATH.)
This will cause RIB to check the update intervals every 15 minutes. On Windows machines,
this can be done through the "Scheduled Tasks" system tool in a similar way.
