​​​​​​​介绍

在以openstack为底层开发的一些项目中，常常会遇到项目中数据与openstack数据不同步的问题，为了简化清空无效数据的繁琐，提供以下脚本便于运维操作。

环境变量

[root@cloud ~]# cat admin.sh
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://cloud:35357/v3
export OS_IDENTITY_API_VERSION=3

脚本示例

[root@cloud ~]# cat clean.sh
source /root/admin.sh#删除无项目虚拟机
project_id=`openstack project list |awk '{print $2}'`
vms=`nova list  --all-tenants |awk -F'|' '{print $2,$3,$4,$5}'|grep -v "ID"`
ifs_old=$IFS
IFS=$'\n'
echo "开始清除无效虚拟机"
for vm in $vms
do
{
vm_id=`echo $vm |awk '{print $1}'`
p_id=`echo $vm |awk '{print $3}'`
name=`echo $vm |awk '{print $2}'`
if [[ $project_id =~ $p_id ]]
then
sleep 0
else
nova delete $vm_id 2&>/etc/null
echo "清除虚拟机($name)"
fi
}&
done
wait
