salt.modules.lvs¶

Support for LVS (Linux Virtual Server)

salt.modules.lvs.add_server(protocol=None, service_address=None, server_address=None, packet_forward_method='dr', weight=1, **kwargs)¶

Add a real server to a virtual service.

protocol: The service protocol(only support tcp, udp and fwmark service).
service_address: The LVS service address.
server_address: The real server address.
packet_forward_method: The LVS packet forwarding method(dr for direct routing, tunnel for tunneling, nat for network access translation).
weight: The capacity of a server relative to the others in the pool.

CLI 范例:

salt '*' lvs.add_server tcp 1.1.1.1:80 192.168.0.11:8080 nat 1

salt.modules.lvs.add_service(protocol=None, service_address=None, scheduler='wlc')¶

Add a virtual service.

protocol: The service protocol(only support tcp, udp and fwmark service).
service_address: The LVS service address.
scheduler: Algorithm for allocating TCP connections and UDP datagrams to real servers.

CLI 范例:

salt '*' lvs.add_service tcp 1.1.1.1:80 rr

salt.modules.lvs.check_server(protocol=None, service_address=None, server_address=None, **kwargs)¶

CLI 范例:

salt '*' lvs.check_server tcp 1.1.1.1:80 192.168.0.11:8080

salt.modules.lvs.check_service(protocol=None, service_address=None, **kwargs)¶

Check the virtual service exists.

CLI 范例:

salt.modules.lvs.clear()¶

Clear the virtual server table

CLI 范例:

salt '*' lvs.clear

salt.modules.lvs.delete_server(protocol=None, service_address=None, server_address=None)¶

Delete the realserver from the virtual service.

protocol: The service protocol(only support tcp, udp and fwmark service).
service_address: The LVS service address.
server_address: The real server address.

CLI 范例:

service_address: The LVS service address.

CLI 范例:

salt '*' lvs.delete_service tcp 1.1.1.1:80

salt.modules.lvs.edit_server(protocol=None, service_address=None, server_address=None, packet_forward_method=None, weight=None, **kwargs)¶

Edit a real server to a virtual service.

protocol: The service protocol(only support tcp, udp and fwmark service).
service_address: The LVS service address.
server_address: The real server address.
packet_forward_method: The LVS packet forwarding method(dr for direct routing, tunnel for tunneling, nat for network access translation).
weight: The capacity of a server relative to the others in the pool.
