Servers:Hercules

Adding a new vserver

• As root on hercules:
• First create the template the server will use for portage

# cd /etc/managed-portage/
# rsync -avP hosts/TEMPLATE_webdb/ hosts/sr-hercules$$

• Commit the new vserver's template to git

# git add /hosts/sr-hercules$$
# git commit -m 'New VM, Hercules$$'
# git push

• Create the new vserver

# cd ~/vps-siat/scripts/
# ./make-vps sr-hercules$$ br0:10.0.1.XX/16 br0:209.87.56.XX/24

• Note that $$ must be the number of the new vserver, which start at 00.
• Further note that XX is the IP to be assigned to the new server. Be very careful not to assign an already taken IP.

Removing an existing vserver

• As root on hercules:
• First ensure that the Vserver is stopped

# vserver sr-hercules$$ stop

• Kill the server

# cd ~/vps-siat/scripts/
# ./kill-vps sr-hercules$$

• Note that $$ must be the number of the vserver.

Working with managed-portage profiles

• It is very important that you DO NOT touch /etc/portage/ on any vserver. Everything must be done through /etc/managed-portage/ on the master server.
• Below are a few common tasks for managed-portage

Setting up vserver-specific USE flags

• As root on hercules:

# cd /etc/managed-portage/hosts/sr-hercules$$/make.profile/

• Here you can create/edit any regular files you would under /etc/portage/, such as package.use for example:

# vim package.use

• Specify what USE flags you'd like a package to use
• Commit the changes to git

# git commit -m '$MESSAGE' package.use
# git push
# cd /vservers/sr-hercules$$/etc/managed-portage/
# git pull

• Note that $$ must be the number of the new vserver, which start at 00.
• Also note that you must replace package.use with whatever file you edited/created.

Changing or setting the profile of a vserver

• As root on hercules:

# cd /etc/managed-portage/class/$PROFILE

• Add the name of the vserver to the applies_to file (if your vserver is sr-hercules99, add 'sr-hercules99' to a new line in the file)
• Commit the changes to git

# git commit -m "$MESSAGE' applies_to
# git push

• Enter the vserver

# vserver sr-hercules$$ enter

• Pull the changes from git and emerge

# cd /etc/managed-portage/
# git pull
# emerge -knN @system ; emerge -knN @world ; emerge -knN @installed
