Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
In the embodiment of the present invention, each server node may be a member of a plurality of server clusters. It should be noted that, for each server cluster, a group length is determined from all the group members in the server cluster. For a certain server node in the server cluster, if the server node is the group leader, a group leader identifier is set in the group member label of the server node, and if the server node is not the group leader, a common member identifier is set in the group member label of the server node.
Fig. 1 illustrates a workflow of a method for building a server cluster according to an embodiment of the present invention, and for convenience of description, only a part related to the embodiment of the present invention is illustrated.
As shown in fig. 1, the method for establishing a server cluster provided in the embodiment of the present invention includes a step a1, a step a2, a step A3, a step a4, and a step a 5.
step a1, a channel is established at the channel layer, through which a join event is issued to join a specified cluster.
It should be noted that, for a server cluster accessible to the server node, in the embodiment of the present invention, one or more server clusters selected in advance from the accessible server clusters are used, and the selected server cluster is used as the designated cluster.
In the embodiment of the invention, the names of one or more appointed clusters are preset in the server node; if the server node needs to be added into a certain designated cluster, a channel needs to be correspondingly established. If the server node is expected to be added into a plurality of designated clusters, a channel needs to be established for each designated cluster.
and through a channel, a join event for joining a specified cluster can be issued.
In the embodiment of the present invention, each channel is established in a channel layer (i.e., channel layer). After a channel is established for a task joining a designated cluster, a joining event is triggered through the channel and is sent to a group service layer (namely GMS layer); the request to join the specified cluster is triggered by the join event.
In the embodiment of the present invention, the group service layer of the server node may perform statistics on each server cluster (including an accessed server cluster and a server cluster that is not accessed temporarily) that the server node can access, and perform statistics on the name of each server cluster.
in addition, the group service layer also performs member information statistics on each server cluster accessed by the server node, including: a name of each server node in the server cluster (e.g., the HOST name of the server node), a physical address of each server node in the server cluster, and a panelist tag for each server node in the server cluster; wherein the panelist tag includes: information whether the server node joined the server cluster. If the server cluster is added, the member tag further records an identifier; specifically, if the server node is the group leader of the server cluster, the identifier of the group member tag record is the group leader identifier; and if the server node is not the group leader of the server cluster, the identifier of the member tag record is a common member identifier.
for each server cluster which is accessed, when the member of a certain server cluster has update (namely a certain server node is newly added in the certain server cluster or a certain server node is withdrawn from the certain server cluster), the group leader of the certain server cluster updates the member list; that is, if a certain server node is added to the server cluster, the member information of the server node (including the name, physical address and group member tag of the server node) is added to the member list; if a server node exits from the server cluster, the member information of the server node (including the name, physical address and group member tag of the server node) is deleted from the member list. Each time the group leader of the server cluster updates the member list, the updated member list is sent to each member (server node in the server cluster). It should be noted that, if the server node is not the group leader of the server cluster, the server node receives the updated member list (the member list sent by the group leader of the server cluster); if the server node is the group leader of the server cluster, the server node updates the member list and sends the updated member list to each member of the server cluster.
Step A2, when the joining event is monitored, generating a searching event for searching the members of the specified cluster.
In the embodiment of the present invention, for a server cluster that wants to join (a server cluster specified by the joining event), the group service layer in the server node only knows the name of the server cluster (which is preset), but does not know the member list of the server cluster; thus triggering step a 2; by executing step a2, a search event for searching the group member of the designated cluster is generated when the join event is monitored, and the group service layer issues the search event to the transport layer through the discovery layer.
As a preferred embodiment, a group search unit is added in the group service layer; correspondingly, the step of generating a search event for searching the members of the designated cluster when the join event is monitored specifically includes: and when the group searching unit monitors the joining event, the group searching unit generates a searching event for searching the members of the specified cluster.
In the preferred embodiment, a group search unit is added to the group service layer; the group searching unit monitors events issued by a channel layer in real time, and if the joining event is monitored, the group searching unit generates searching events of the members of the designated group. If other events are heard (not the join event), the event is either discarded directly or forwarded.
For the search event generated by the group search unit, the group search unit sends the search event to the discovery layer so as to forward the search event to the transmission layer, the network layer and the network interface layer in sequence; and broadcasting the search event through the network interface layer, and sending the search event to the designated cluster and other server nodes.
As an implementation manner of the above preferred embodiment, a search execution unit is added in the discovery layer; correspondingly, before the step of broadcasting the search event to the plurality of server nodes, the method for building a server cluster further includes: and when the search execution unit monitors the search event issued by the group search unit, the search execution unit issues the search event to a transmission layer.
in this embodiment, a discovery layer is located between the group service layer and the transport layer. A search execution unit and a parsing unit are added in the discovery layer. When monitoring the search event issued by the group search unit, the search execution unit forwards the search event to the transport layer through the analysis unit.
In addition, when a certain server node sends a feedback event (carrying member information such as a physical address and a group member tag of the server node) to the node server, after passing through a network interface layer and a network layer of the node server, a transport layer of the node server detects the feedback event. Furthermore, the transport layer of the node server sends the feedback event to the discovery layer, the parsing unit in the discovery layer parses the member information such as the physical address and the member tag specified by the feedback event (the member information such as the physical address and the member tag of the server node) from the feedback event, and the parsing unit sends the parsed member information such as the physical address and the member tag to the group service layer. Furthermore, the detection unit provided in the group service layer can determine (according to the panelist tag) that the server node belongs to the designated cluster.
step a3, broadcasting the lookup event to a plurality of server nodes.
In the embodiment of the present invention, after the discovery layer sends the search event to the transport layer, the transport layer protocol in the TCP/IP protocol may be used to encapsulate the search event, and encapsulate the search event into a message, and send the message to the network layer, so that the network layer sends the message to the network interface layer, and the network interface layer broadcasts the message carrying the search event. In a specific embodiment of the present invention, a tunnel protocol is used to send a message carrying the lookup event to a plurality of server nodes. In a specific embodiment of the present invention, a Transmission Control Protocol (TCP) is used to unicast a message carrying the search event to a plurality of server nodes. In a specific embodiment of the present invention, a User Datagram Protocol (UDP) is used to broadcast a message carrying the search event to a plurality of server nodes.
as a preferred embodiment of the present invention, the step of broadcasting the search event to a plurality of server nodes specifically includes: and broadcasting the search event to the server node by using a User Datagram Protocol (UDP) by adopting an IP Multicast technology (IP Multicast, which sends an IP Multicast packet to a plurality of host groups on the same physical or virtual data link layer).
In the preferred embodiment, the lookup event is broadcast by an IP multicast technique (i.e., multicast or multicast), which allows the server node to send the same packet (e.g., a message carrying the lookup event) to multiple server nodes simultaneously.
step A4, when a feedback event is monitored, the feedback event is resolved, and a physical address and a member tag specified by the feedback event are resolved, and the feedback event is fed back to the server node by the server node.
in the embodiment of the invention, a feedback monitoring unit is also added in the discovery layer.
After the server node broadcasts to other server nodes (including server nodes in a designated cluster), the server node waits for feedback of other server nodes, namely the server node monitors a feedback event; if the feedback monitoring unit of the server node monitors a feedback event, the server node sending the feedback event receives and feeds back the search event (broadcasted by the server node), the feedback monitoring unit sends the feedback event to the analysis unit in the discovery layer, and the analysis unit analyzes the feedback event and analyzes the group member information such as the physical address and the group member label specified by the feedback event.
in addition, a detection unit is added on the group service layer. When the analyzing unit sends the analyzed member information such as the physical address and the member tag to the detecting unit, the detecting unit executes step a5 to detect whether the server node with the member tag is the member of the designated cluster, and if the server node is the member of the designated cluster, further detects whether the server node with the member tag is the group leader of the designated cluster.
Step A5, detecting the group member label, if detecting the group length identification from the group member label, applying for joining the appointed cluster to the server node with the group length identification according to the physical address.
in the embodiment of the present invention, since the search event is broadcasted, the server node responding to the search event is not necessarily the server node in the designated cluster, but the server node feeds back one feedback event after responding to the search event. And executing a step A5 to resolve the panelist tag from the feedback event.
in the embodiment of the present invention, the panelist tag records: whether the server node with the member label is a member of the designated cluster, which server clusters the server node with the member label is a common member (determining which server cluster the server node is a common member according to the common member identification in the member label), and whether the server node with the member label is a group leader of one or more server clusters. And if the group member label also carries a group leader identifier, determining the group leader of which server cluster the server node belongs to by the group leader identifier.
In this embodiment of the present invention, if in step a5, the group leader identifier is found from the group member tag, which indicates that the server node having the group member tag is the group leader of the specified cluster. If the server node wants to join the designated cluster, an application needs to be sent to the server node with the group leader identifier, and the application becomes a common member of the designated cluster.
as a preferred embodiment, if it is determined that the performance (e.g., storage space and/or processing speed) of the server node is better than that of the server node having the group leader identifier, the server node having the group leader identifier is adjusted to be a normal member (i.e., the identifier of the server node having the group leader identifier is adjusted to be a normal member identifier), and the server node is adjusted to be the group leader (i.e., the identifier of the server node is adjusted to be the group leader identifier).
fig. 2 illustrates an optimized workflow of a method for building a server cluster according to an embodiment of the present invention, and for convenience of description, only a part related to the embodiment of the present invention is illustrated.
as a preferred embodiment of the present invention, as shown in fig. 2, the method for establishing a server cluster further includes:
step a6, if the group leader id is not detected from the group member tag, setting a group leader id in the group member tag of the server node.
in the preferred embodiment, since it is not necessary that the server node in the designated cluster responds to the search event, the server node will feed back one feedback event after responding to the search event; the panelist tag may then be parsed from the feedback event.
Further, for each server node which has fed back the feedback event, according to the member tag of the feedback event, determining that each server node which has fed back the feedback event is not a member of the designated cluster; or the group leader identifier is not searched from the group member label of the feedback event; the server node is taken as the group leader of the designated cluster. If other server nodes wish to join the designated cluster, the request is required to be applied to the server node.
Therefore, when the server node detects the group leader of the specified cluster according to the group member label, the server node applies for the group leader of the specified cluster to join the specified cluster. When the server node does not detect the group length of the designated cluster according to the member label, the server node is set as the group length of the designated cluster, and other server nodes which want to join the designated cluster need to apply for the server node to successfully join the designated cluster.

as an embodiment of the present invention, as shown in fig. 3, a physical address obtaining unit and a feedback unit are respectively added to the discovery layer;
correspondingly, the method for establishing the server cluster further comprises the following steps:
Step a7, after the server node joins the designated cluster, if the physical address obtaining unit monitors a search event sent by a new server node, extracting the physical address of the server node, and the physical address obtaining unit sends the physical address of the server node to the feedback unit;
step A8, the feedback unit generates a feedback event including the physical address of the local server node and the panelist tag of the local server node, and feeds back the generated feedback event to the new server node.
In the preferred embodiment, when a new server node wishes to join the designated cluster, the new server node also broadcasts a search event, and the discovery layer of the server node monitors the search event (broadcasted by the new server node), acquires the physical address of the server node, and sends the physical address to the feedback unit. Then, the feedback unit generates a feedback event carrying member information of the server node (including a name, a physical address, a group member tag, and the like of the server node), and sends the feedback event to the new server node, and the analysis unit of the new server node monitors the feedback event and analyzes the member information of the server node from the feedback event.
The new server node is the same as the working principle of the server node, the detection unit of the new server node detects whether the member label of the server node belongs to the appointed cluster or not and detects whether the member label of the server node comprises the group length identification or not, if the member label of the server node comprises the group length identification, the new server node needs to apply for joining the appointed cluster to the server node, if the member label of the server node does not comprise the group length identification, the new server node needs to send a request for joining the appointed cluster to the server node with the group length identification, and if the new server node does not detect the server node with the group length identification, the new server node sets itself as the group length.
