Bash script to create a full software development environment

I have create this (first version) script to automatize the creation of all the services related with a new software development project.

The script creates…

  • A new Subversion repository to host the source code of the project.
  • A new MySQL database to store the data of the Trac instance.
  • A new instance of Trac, linked to the just created Subversion repository, to be used like the project’s portal.
  • A configuration file for Apache2 in order to made accesible the Trac repository.

The structure of the new Subversion repository is as follows:

-> branches
-> tags
-> trunk
   -> docs
   -> src

The environment used was the following

  • Ubuntu Server 11.04 64 bits
  • Apache/2.2.17 (installed from the Ubuntu repositories)
  • MySQL Server 5.1.541ub (installed from the Ubuntu repositories)
  • Subversion 1.6.12 (installed from the Ubuntu repositories)
  • Python 2.7.1+ (installed from the Ubuntu repositories)
  • Trac 0.12

TODO

  • Implement checking to ensure that the different elements do not exists before trying to create them (for example the Subversion repository, or the MySQL database).
  • Implement the installation of the Subversion hooks that ensure that the Trac instance keeps in sync with the Subversion repository
