如何删除 OpenStack Nova 僵尸实例

Posted 2023-03-22

参考技术A #!/bin/bash
for i in "$@"
do
mysql -uroot -pmygreatsecret << EOF
use nova;
DELETE FROM nova.virtual_interfaces where instance_uuid='$i';
DELETE FROM nova.fixed_ips where instance_uuid='$i';
DELETE FROM nova.block_device_mapping where instance_uuid='$i';
DELETE FROM nova.instance_system_metadata where instance_uuid='$i';
DELETE FROM nova.security_group_instance_association where instance_id='$i';
DELETE FROM nova.instance_info_caches WHERE instance_uuid='$i';
DELETE FROM nova.instances WHERE uuid='$i';
EOF
done
#echo "ok!,$# vm was deleted successfully!!"
#exit 0

运行脚本时后面加参数 ，参数为你要删除的实例的id，例如：
22f8d28d-d6cd-461e-911f-627e6cb8d4fe

在实例所在的计算结点上删除/var/lib/nova/instance/instance00000[这个是要删除的实例的号]本回答被提问者和网友采纳

sh 查询openstack nova实例

# CTL

function nova-show-vm() {

 salt $1 cmd.run "virsh list --all";
 ping -c3 $2;
}
instance-check $(instance-placement $IP)



function getip ()

    getent hosts $1 | awk '{ print $1 }'
}

  test -e $TEMPCAHCE || {
    nova-manage vm list | column -t > $TEMPCAHCE
  }
  egrep $@ "$TEMPCAHCE" | egrep -v deleted | awk '{print $7,$2,$1,$4}'
}

  
  
  
## associate Floating IPs by instance name
declare PORTS=($(nova list  --all-tenants|egrep -i '(gb-ss-vos-node-iyvooqnuxvqj-4jqzkrgqbcbx-r3ey62hav3ge|gb-ss-vos-node-iyvooqnuxvqj-zi3eglyjffrd-n7xcuwcgkjlg|gb-ss-.....)' |awk -F"|" '{print $2}' | xargs neutron port-list --device-id  |awk -F"|" '{print $2}'|xargs))

for i in $(seq 1 ${#PORTS[@]}); do echo neutron floatingip-associate ${FFIPS[$i]} ${PORTS[$i]};done


## get logs from stack
nova console-log $(openstack stack resource show 87dd6864-f004-467f-9725-39e67e59dbd2 mcp_salt_master -f json | jq -cr '.attributes.instance')
