unstack doesn't clean out /opt/stack. or purge all dependency packages. or clean all eggs out of python.

I recommend running devstack in a VM. It's easy enough to simply remove the VM and rebuild from scratch.

Example shell script for creating a devstack VM for kvm:

<pre><code>#!/bin/sh

/usr/bin/vmbuilder kvm ubuntu -v --suite=oneiric --libvirt=qemu:///system --flavour=server --arch=amd64 --cpus=2 --mem=4096 --swapsize=2048 --rootsize=30480 --ip=192.168.122.236 --hostname=devstack --user=stack --name=stack --pass=stack --addpkg=git --addpkg=screen --addpkg=vim --addpkg=strace --addpkg=lsof --addpkg=nmap --addpkg=subversion --addpkg=acpid --addpkg=tcpdump --addpkg=python-pip --addpkg=wget --addpkg=htop --mirror=http://us.archive.ubuntu.com/ubuntu --components='main,universe' --addpkg=openssh-server --dns=8.8.8.8 --dest=/virts/devstack
</code></pre>

blocks|key|5258509|text|unstack.sh脚本仅停止服务，而不删除它们。Devstack的文件夹包含一个clean.sh脚本，该脚本删除了openstack和依赖项，因此您可以运行如下代码：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|5258510|cd+path/to/devstack

#+There's+no+need+to+call+unstack.sh+explicitly

The unstack.sh script only stops the services without removing them.
Devstack's folder contains a clean.sh script that removes openstack and dependencies so you can run something like this:

<pre><code>cd path/to/devstack

# There's no need to call unstack.sh explicitly
# clean.sh invokes that script itself.
./clean.sh
</code></pre>

Follow the following 3 steps:

<ol>
<li><code>./clean.sh</code></li>
<li><code>rm -rf /opt/stack</code></li>
<li><code>rm -rf /usr/local/bin</code> (careful, this will remove everything installed to your local bin folder, which might include previously installed applications).</li>
</ol>

I am installing OpenStack on my local machine via <a href="http://devstack.org/guides/single-machine.html" rel="nofollow">this</a> link. But I am having trouble in completely removing installed components from my local machine. I ran following command:-

<pre><code>$ sudo ./unstack.sh
tgtadm: can't send the request to the tgt daemon, Transport endpoint is not connected
tgtd seems to be in a bad state, restarting...
stop: Unknown instance: 
tgt start/running, process 14629
tgt stop/waiting
Volume group "stack-volumes" not found
Skipping volume group stack-volumes
</code></pre>

And file are still present in /opt/stack and /usr/local/bin/. But manually removing these file will not be a good option.

Completely remove openstack from system after installation from devstack script
