This article mainly introduces what is the use of neutron database in openstack. It is very detailed and has certain reference value. Friends who are interested must finish reading it.

I. the overall architecture of the Neutron database

Neutron Database adopts a distributed architecture, which consists of three servers to form a cluster.Neutron Server through Plugin, and then sends it to the VIP of Neutron Database. After receiving the message, HAProxy forwards it to the real address of database.

The 1.Neutron server receives the api request.

2.plugin conversion message, sent to database

3.database saves the neutron network state.

4.HAProxy realizes active and standby protection of data

II. Neutron database and fields
