Removing Nova and Neutron Services from Mysql

Some times we need to remove the services listed in the Nova or neutron as they are duplicated or they are removed from the entire system. So we can do it in the following way.

Removing Nova Service from Mysql Database. 

>>nova service-list
>>nova hypervisor-list

mysql> use nova;
mysql> SELECT id, created_at, updated_at, hypervisor_hostname FROM compute_nodes;

mysql> DELETE FROM compute_node_stats WHERE compute_node_id='1';
mysql> DELETE FROM compute_nodes WHERE hypervisor_hostname='compute1';
mysql> DELETE FROM services WHERE host='compute1';

Removing Nneutron  Service from Mysql Database. 

>>neutron agent-list

mysql> use neutorn
mysql> DELETE FROM agents WHERE host='compute1';
