Fedora 2.1.1 setup

The Fedora package goal is describing exact steps needed to install the Fedora repository in a way suitable for use in our DOMS project.

Introduction

The basis for our metadata storage in the DOMS system, is a Fedora repository. The Fedora repository needs not be on the same machine as the rest of the DOMS system, but can be communicated with through different web services through HTTP/SOAP, HTTP REST-based, or OAI harvesting.

Requirements

• Java 1.5
• A MySQL database

For a full-scale Fedora installation, furthermore you need the following:

• Decent processor power (e.g. a Xeon 3GHz dual-CPU machine)
• at least 4GB RAM, preferably more.
• 400GB+ fast harddisks
• 64 bit operating system
• 64 bit Java 1.5
• A filesystem that can handle 10 million+ small files.
  • Tip: Turn off updating of the lastAccessed timestamp on the file system. This speeds up harddisk access for Fedora.
  • Tip: Consider putting the MySQL database on a separate harddisk for faster access/update time, about 1/10th of the space should be allocated for this.

Installation instructions

Installing MySQL

If you do not yet have MySQL installed, you need to do this, set the password, and start it up.

For Fedora Core Linux 3 or above, or Redhat Enterprise Linux 4 or above, you should be able to install MySQL, and make it start up at system boot, with the following commands:

sudo yum install mysql-server

Continue with:

sudo /sbin/chkconfig mysqld on
sudo /sbin/service mysqld start

which enables start of MySQL server on startup.

Now you should set the root password:

/usr/bin/mysql -u root
mysql> set password for root@localhost=password('new-password');
mysql> set password for root@<<$HOSTNAME>>=password('new-password');

(Remember to replace <<$HOSTNAME>> with your host name)

Installing MySQL on Windows

A starting point: http://dev.mysql.com/doc/refman/5.0/en/windows-installation.html

Go to http://dev.mysql.com/downloads/mysql/5.0.html#downloads and select the "Windows (x86) ZIP/Setup.EXE" package.

• Unpack & execute the installer.

• Select "Typical".
• Skip the part with the MySQL.com Sign Up.
• Choose the setup option at the end of the installation (default). Use the choices below in the wizard. Only deviations from the standard selections are described.
  • Detailed Configuration.
  • Developer Machine.
  • Non-Transactional Database Only.
  • Manual Setting for concurrent connections: 100 (the default maximum for Fedora).
  • Turn off "Enable Strict Mode".
  • Best Support For Multilingualism.
  • Include Bin Directory in Windows PATH.

  • Write a root password. Remember it!.

Installing Fedora

These are instructions for installing the Fedora 2.1.1 repository in ~/fedora-2.1.1, with settings as expected by the DOMS installation.

Step 1: Unpack the distribution

The file DOMS/Fedora/fedora-2.1.1-server.tar.gz can be found in our CVS repository. Unpack this in your home directory:

cd ~
tar -xzvf fedora-2.1.1-server.tar.gz

Step 2: Set up your environment variables

Edit the file ~/.bash_profile

Make sure the following environment variables are set (make sure JAVA_HOME points right for your system):

export JAVA_HOME=/usr/java/jdk1.5.0_07
export FEDORA_HOME=~/fedora-2.1.1/
export CATALINA_HOME=~/fedora-2.1.1/jakarta-tomcat-5.0.28/
export PATH=$JAVA_HOME/bin:$FEDORA_HOME/server/bin:$PATH

Log out and log in again to make the change take effect or perform a source ~/.bash_profile in all open terms.

Environment variables under Windows

Navigate to Control Panel | System | Advanced | Environment | System.

JAVA_HOME C:\java\jdk1.5.0_07
FEDORA_HOME C:\fedora-2.1.1
PATH <previous path>;C:\java\jdk1.5.0_07;C:\fedora-2.1.1

Step 3: Set up the MySQL database

The Fedora installation contains a script that handles initialising the database with the expected tables. Run the script with the following command (remember to replace <<YOUR_DATABASE_ROOT_PASSWORD>> with the root password for MySQL):

mysql-config /usr root <<YOUR_DATABASE_ROOT_PASSWORD>> fedora fedora fedora mysql41_flag

If you do not have root access to MySQL, please ask your friendly it-department to run the script for you.

Note: The above command assumes the mysql command is installed as /usr/bin/mysql. If it isn't, replace /usr with the basedir of your MySQL installation (that is excluding bin)

Note 2: Same procedure under Windows, where /usr should be replaced with the path to the MySQL installation. Use double quotes, if the path contains spaces.

Step 4: Setup configuration files

First, run a small script bundled with fedora, that does some basic security setup of the embedded tomcat:

fedora-setup no-ssl-authenticate-apim

Then copy in the custom fedora configuration file from our CVS repository to replace the existing fedora.fcfg

cp <<$CVSROOT>>/Fedora/config/fedora.fcfg ~/fedora-2.1.1/server/config

This sets up fedora with the following properties:

• Using MySQL on localhost initialised as above.
• Starting the server on localhost port 7900, and using ports in the range 7901-7909 for various purposes.
• Using the directory ~/fedora-2.1.1/data for data

For a large scale installation, or an installation accessible from outside localhost, you will need to edit the fedora.fcfg file further. See the Fedora documentation for details.

Step 5: Start the server

fedora-start

Step 6: Test the server is running

Visit the URL

http://localhost:7900/fedora/search

Try searching for *

There should be no results, but no errors either.

Step 7: Setup OAI provider

See SettingUpOAI

Resetting Fedora

To reset a Fedora repository to an empty repository, do the following.

fedora-stop
rm -r ~/fedora-2.1.1/data/objects
fedora-rebuild

choose 1,1

fedora-rebuild

choose 2,1

If you are using the oai provider service, you should also clear the proai cache

mysqldump -uproai -pproai --add-drop-table --no-data proai|grep ^DROP|mysql -uproai -pproai proai

then, finally

fedora-start

Your Fedora repository has now been emptied.
