ManageAllAdminScriptsWithSVN

Goal

We (grid sysadmins) are using a lot of scripts to accomplish a lot of different tasks. The main problem with these scripts is that they are disseminated on several servers. To ease their maintenance, we then decided to manage them from a single SVN repository located on our documentation server (mon).

List of Scripts

We maintain a list of all the scripts that are used, their place and their eventual cron execution ListOfScripts here

Accessing the repo

You need a valid account (see next section for the creation of accounts). Here is the URL of the repo :

http://mon.iihe.ac.be/repos/scripting

Having a quicky look at the content of the repo, you'll see that, under the root, we have created one directory per server.

Creation of a new account

Log in on mon. Edit the file /var/svn/repos/scripting/svnauth. Here is an example :

[/]
stgerard = rw
mdupont = rw

Now, you have to generate the encrypted password for the new created account :

 htpasswd -m /var/svn/repos/scripting/svnpass mdupont

How to copy a new script/project to the central SVN ?

Say that, for example, you've just created a new project, locate in /root/myproject on ccq. Here are the steps to add this new project to the central SVN :

cd /root
svn import -m "new project found in ccq --> myproject" myproject http://mon.iihe.ac.be/repos/scripting/ccq/myproject
cd myproject
svn checkout --force http://mon.iihe.ac.be/repos/scripting/ccq/myproject .

However, if you want to exclude files from the project (temporary, examples, log files, etc.), then, don't use svn import. Instead, do the following :

svn mkdir http://mon.iihe.ac.be/repos/scripting/ccq/myproject -m "creating a new project"
svn checkout --force http://mon.iihe.ac.be/repos/scripting/ccq/myproject
cd myproject
svn checkout http://mon.iihe.ac.be/repos/scripting/ccq/myproject .
svn add <the list of files you want to add, seperated by spaces>
svn commit -m "initial version of myproject"

What if you intend to modify the local copy of a project ?

First of all, before modifying the files, never forget to make an update of the local copy :

cd myproject
svn update

After having modified the files, commit the changes :

svn commit -m "initial version of myproject"

If you have added new files, don't forget to add them :

svn add <the list of files you want to add, seperated by spaces>
