CSEE allows users to request one or more MySQL databases. The accounts given through this interface can do anything standard MySQL can do, with the exception that you are limited to one database. You may request any alphanumeric string as the name of your database, but if someone else has already taken that name they have precedence. The string you give is prepended with "user_", so if you request the database "foo" and nobody has taken it, you will be granted a database by the name "user_foo". We suggest that you pick a name that describes the purpose of your database rather than who owns it, although there is no prohibition on picking, say, your own username as a database name. However, if you're doing a group project, it may be a better idea to pick something related to the project, so if you graduate and someone else takes over the project, the name of the database will be sensible.

To get a CSEE database account, submit a ticket through the standard interface at [https://my.cs.umbc.edu my.cs.umbc.edu]. Mention that you want a database and what name you want for it.

Once you've been granted a CSEE database account, you can connect to it at db1.cs.umbc.edu on port 3306 (the standard port for MySQL), your UMBC username, and the password that you'll be given via email.

Wiki

2009-01-11T00:00:55Z

Willm1:

==How to set up your own wiki==

1. Follow the instructions to [[Web Introduction|set up your personal webspace]].

2. Log in to <tt>sunserver1.cs.umbc.edu</tt>

3. Go to your <tt>www</tt> directory (<tt>cd ~/www</tt>)

4. Run <tt>/usr/site/bin/createwiki.sh <wiki path></tt>. This will create your wiki in <tt>~/www/<wiki path></tt>. For example, <tt>/usr/site/bin/createwiki.sh wiki</tt> will create <tt>~/www/wiki</tt>.

5. Your wiki is now available at <tt><nowiki>http://cs.umbc.edu/~''username''/<wiki path></nowiki></tt>. Follow the instructions there to modify <tt>~/www/<wiki path>/wikiconfig.py</tt> to suit your needs.

Note that creating a wiki will use approximately 10mb of your quota to start, and adding pages will increase its usage. We use [http://moinmo.in/ the MoinMoin wiki engine], if you want to read up on how to use it.

Public Subversion

2009-01-08T19:58:50Z

Willm1:

CS systems have the Subversion versioning system (similar to CVS) installed on them in <tt>/usr/bin/svn</tt>. Private SVN repositories are creatable by means described in [http://svnbook.red-bean.com/ the SVN book], but a method is also provided to create repositories that are publicly accessible over HTTP.

To share a repository in this way, first create it in a directory of your choosing.
willm1@linuxserver1:~$ mkdir svn
willm1@linuxserver1:~$ cd svn
willm1@linuxserver1:~/svn$ svnadmin create myrepo
This will create a directory <tt>myrepo/</tt>, and contents in that directory. This is a fully functional SVN repository:
willm1@linuxserver1:~/svn$ svn checkout file:///home/csee1/willm1/svn/myrepo ~/myrepo
Checked out revision 0.
willm1@linuxserver1:~/svn$ cd ~/myrepo
willm1@linuxserver1:~/myrepo$ echo 'Hello, World!' > greeting
willm1@linuxserver1:~/myrepo$ svn add greeting
A greeting
willm1@linuxserver1:~/myrepo$ svn commit --message "Add a friendly greeting"
Adding greeting
Transmitting file data .
Committed revision 1.
However, this is not yet accessible over the web; even if you put the repository in your web directory, browsing to this directory over HTTP will show the file contents of the SVN repository (<tt>README.txt</tt>, <tt>conf/</tt>, etc.), rather than the SVN contents. To make this happen, the web server needs to be informed that the <tt>myrepo</tt> directory contains SVN information, and SVN should be used to determine what is actually shown over the web. There is a web interface at [http://my.cs.umbc.edu my.cs.umbc.edu] that can be used to accomplish this. Go there, and log in using your UMBC username and password as normal. Under "CSEE Account", click on "Subversion". You should see a menu like this:
[[Image:svn-repo.png]]

In the box on the left, fill in the name that will be visible over HTTP. For example, <tt>myrepo</tt> would be a good choice for this repository, but if something more descriptive applies to your code you may choose whatever you like. In the box on the right, fill in the path to your repository, excluding the part which is your home directory. For example, the full path to the repository I created is <tt>/home/csee1/willm1/svn/myrepo</tt>, and my home directory is <tt>/home/csee1/willm1</tt>, so I would enter <tt>svn/myrepo</tt> in the box. Finally, click "Add" to make the changes take effect. Your repository will be exposed immediately, and the interface will look like this:
[[Image:svn-repo-created.png]]

You can click on the link under "URL" to take you directly to the repository. Congratulations, your repository is completely set up!

If you are using the directory-listing feature of Apache to generate an <tt>index.html</tt> file for your CS account webpage, do not create a directory with the same name as the name you gave your repository, so that the repository shows up in that list. This will prevent others from checking out your repository properly using an svn client. It will still be accessible over the web, but error messages like the following will be generated:
willm1@chasca:/tmp$ svn checkout http://www.csee.umbc.edu/~willm1/myrepo/
svn: PROPFIND request failed on '/~willm1/myrepo'
svn: PROPFIND of '/~willm1/myrepo': 301 Moved Permanently (http://www.csee.umbc.edu)
It is recommended, instead, to create an HTML page that lists the things available on your web site.

==Debugging==
You may need to make sure that this directory is readable by the webserver. The web server currently runs with group id 48 (apache), so if you don't wish to give "o+rx" permissions on this directory you may use
chgrp -R apache ~/svn
chmod -R g+rx ~/svn
Otherwise, a simpler set of permissions can be given:
chmod -R o+rx ~/svn
Depending on your configuration, this step may not be necessary. If you run into a problem with this and are unable to make your repository visible, please submit a ticket detailing the problem via the [http://my.cs.umbc.edu my.cs.umbc.edu interface].
