откройте сервер базы данных vSwitch (Open vSwitch database server)
Описание (Description)
The ovsdb-server program provides RPC interfaces to one or more
Open vSwitch databases (OVSDBs). It supports JSON-RPC client
connections over active or passive TCP/IP or Unix domain sockets.
For an introduction to OVSDB and its implementation in Open
vSwitch, see ovsdb(7).
Each OVSDB file may be specified on the command line as database.
Relay databases may be specified on the command line as
relay:schema_name:remote. For a detailed description of relay
database argument, see ovsdb(7). If none of database files or
relay databases is specified, the default is
/usr/local/etc/openvswitch/conf.db. The database files must
already have been created and initialized using, for example,
ovsdb-tool's create, create-cluster, or join-cluster command.
This OVSDB implementation supports standalone, active-backup,
relay and clustered database service models, as well as database
replication. See the Service Models section of ovsdb(7) for more
information.
For clustered databases, when the --detach option is used,
ovsdb-server detaches without waiting for the server to
successfully join a cluster (if the database file is freshly
created with ovsdb-tool join-cluster) or connect to a cluster
that it has already joined. Use ovsdb-client wait (see
ovsdb-client(1)) to wait until the server has successfully joined
and connected to a cluster. The same is true for relay
databases. Same commands could be used to wait for a relay
database to connect to the relay source (remote).
In addition to user-specified databases, ovsdb-server version 2.9
and later also always hosts a built-in database named _Server.
Please see ovsdb-server(5) for documentation on this database's
schema.
