About Scarab
Scarab is a highly customizable artifact tracking system. ( http://scarab.tigris.org/ )
A good replacement for bugzilla, and also has import scripts to import bugzilla issues.
Read about scarab:
http://www.solitone.org/scarab-trunk-doc/index.html
and Scarab design:
http://www.solitone.org/scarab-trunk-doc/misc/scarab-design.html
Installation
Install Tomcat as described here: Tomcat
Then open mysqld access to local network because Scarab use the mysqld port instead the socket.
The following instructions are extracted from MySQL#Access_MySQL_from_the_local_network
config setprop mysqld LocalNetworkingOnly no expand-template /etc/my.cnf sv t /service/mysqd
In some circunstances mysqld fail to start. If this is your case, reboot the server.
Install:
yum --enablerepo=smecontribs install scarab
The installation create scarab db and scarabu user.
Under /opt/scarab you have found the extensions directory, and can be use the scripts to import data from bugzilla.
Under /db/mysql you have found the database creation scripts. The installation use install_db_plain.sql. This script install a plain db for Scarab. If you want to install sample data, when finish the installation, execute:
mysql < install_db_with_sample.sql
The script remove the old db and create a new one with sample data.
You can always return to the plain db executing:
mysql < install_db_plain.sql
Usage
Access http://yourdomain:tomcatport/scarab
The default username is Administrator with password 1 (number one)
Conclusion
Read all the documentation available from Scarab site. The mailing list is a good source of information too.
I think Scarab is a good tool to try and test over bugzilla.
As always, report any bug
