Useful Scripts

Tom Elliott

Hey all,

I know this probably seems rather random, but this is just a place for me to put some of my scripts during programming for FOG.

While these are specifically setup for my environment, simple edits can make them portable.

If you all want to try your hand on these for your own projects, feel free.

Copy to svn
– All this does is take my files as I have edited them and copies them to my trunk directory for subversion/svn.
– I call it copytosvn
– The extra “trunk2” stuff you see is for btsync when that was running.
– if I call it as copytosvn git it will do the same as for trunk, but to only the git. This was added due to sourceforge being down last year.

Copy back trunk
– Copies the file in the trunk folder back to the base folder. Useful if i’m making changes that seem to break things and just need to start fresh, or if something needs to be looked at as its broken, but known working in older version. Allows me to revert the folder and copy back the files in the trunk to the base so I can see things more clearly.
– Create a backup of your original config.class.php in the root directory.
– I named it copybacktrunk

#!/bin/bash
rm -rf /var/www/fog;cp -r ~/trunk/packages/web /var/www/fog; cp ~/config.class.php /var/www/fog/lib/fog/config.class.php;chown -R apache:apache /var/www/fog; chown -R 500:apache /var/www/fog/service/ipxe

Build buildroot
– Copies the files from the main trunk directory of a remote system (my dev box) and places the files where needed.
– Does require pre-environment setup (config files etc… already in place.
– I call it buildBuildroot
– Copies the init’s back to my other servers as needed.

Build iPXE
– Build’s the ipxe files and updates the trunk version via remote methods now.
– I call it buildIpxe
– Adding arguments just add iPXE arguments to build with extra args.
For example: buildIpxe DEBUG=dhcp will build the ipxe files with the DEBUG=dhcp enabled on the built files.

Init redo
– Allows me to redo the inits without having to do a full rebuild
– I call it init_redo.sh

Fog git sync
– Syncs the git respository with the svn repository information
– I call it foggitsync.sh
– Only used to sync/merge the dev-branch information

#!/bin/bash

cd /root/fogproject
# Sync SVN with git repo
git checkout svn 
git svn -A authors.txt rebase
git commit -a --allow-empty-message -m ''
# Merge changes from svn to dev-branch
git checkout dev-branch
git pull origin dev-branch
git merge --strategy-option=theirs svn -m 'Merge svn with dev-branch'
# Push changes to remote
git push origin svn dev-branch

Just quickly copy/pasting some scripts I made for managing 15 storage nodes without killing myself.

I’m going to take all these and other stuff community has made and pile them all up into one big git repo called “Fog Tools” or something.

All of the below scripts in this post are dependent on ssh-pki being setup from the server to all nodes and having aliases created for them all, I have created a tool that helps you do this: https://github.com/wayneworkman/ssh-pki-setup
