下面的腳本可以完全卸載RDO，包括所有的程序數據，組件包等。
注意：這里假設你在這臺機器上面只跑了Openstack！如果這臺機器還有其他用途，那么請使用Slightly smaller hammer method這個方法。

Slightly smaller hammer method
下面的腳本只刪除特定的程序數據和組件包，會留下一些Openstack相關的數據。

for x in $(virsh list --all | grep instance- | awk '{print $2}') ; do virsh destroy $x ; virsh undefine $x ; done ; yum remove -y "*openstack*" "*nova*" "*keystone*" "*glance*" "*cinder*" "*swift*" "*rdo-release*";# Optional - makes database cleanup cleaner. # If you do this bit, the database cleanup stuff below is superfluous. # yum remove -y "*mysql*"ps -ef | grep -i repli | grep swift | awk '{print $2}' | xargs kill ;rm -rf /etc/yum.repos.d/packstack_* /var/lib/glance /var/lib/nova /etc/nova /etc/swift \ /srv/node/device*/* /var/lib/cinder/ /etc/rsync.d/frag* \ /var/cache/swift /var/log/keystone /tmp/keystone-signing-nova ;# Ensure there is a root user and that we know the password service mysql stop cat > /tmp/set_mysql_root_pwd << EOF UPDATE mysql.user SET Password=PASSWORD('MyNewPass') WHERE User='root'; FLUSH PRIVILEGES; EOF# mysql cleanup /usr/bin/mysqld_safe --init-file=/tmp/set_mysql_root_pwd & rm /tmp/set_mysql_root_pwd mysql -uroot -pMyNewPass -e "drop database nova; drop database cinder; drop database keystone; drop database glance;"umount /srv/node/device* ; vgremove -f cinder-volumes ; losetup -a | sed -e 's/:.*//g' | xargs losetup -d ; find /etc/pki/tls -name "ssl_ps*" | xargs rm -rf ; for x in $(df | grep "/lib/" | sed -e 's/.* //g') ; do umount $x ; done

還可以，使用單條命令
