The core of the invention is to provide a cifs service backup switching method, which can realize stable, reliable and easy-to-realize cifs service backup switching.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a cifs service backup switching method in an embodiment of the present invention, where the method includes the following steps:
s101, the first node determines a second node which is used for cifs system service backup together with the first node and is connected to the second node;
determining a first node and a second node under the storage equipment of the cifs system as two nodes commonly used for the business backup of the cifs system, wherein the first node and the second node are only used for distinguishing the two nodes. In order to reduce the risk of heartbeat disconnection caused by network fluctuation due to network crossing network segments, a first node and a second node of a storage device in a cifs system can be selected to be located in the same switching network as two nodes commonly used for business backup of the cifs system, that is, the lower ports of the storage devices to which the first node and the second node belong are located in the same switching network, and of course, the first node and the second node can also be determined according to other use requirements.
It should be noted that the two nodes commonly used for the service backup of the cifs system are not in a complete main-standby relationship, and both can run the service and can switch the service to the opposite end node.
After determining a second node, which is used for cifs system service backup together with a first node, the first node needs to be connected to the second node, and a specific connection manner is not limited in this embodiment, and one implementation manner is as follows:
(1) the first node determines the ip inside the node and the name of the connected host;
the ip inside the node indicates the connected network segment, and the name of the connected host indicates the service object.
The determination method of the internal ip and the host name of the connection is not limited in this embodiment, the internal ip may be determined by obtaining network configuration information of the internal ip, and the first node may also set the node internal ip according to a heartbeat port specified in the configuration file. And appointing a heartbeat port and a heartbeat port network segment in the equipment configuration file, setting an internal ip of a node according to the appointed heartbeat port in the configuration file, and generating a host name so as to be flexibly configured according to actual network deployment.
(2) Sending the local node information to a second node; the local end node information comprises a host name;
connecting an opposite end (second node) ip, and sending node information including a home name of the home end to the opposite end, wherein the node information is mainly used for secret-free connection and establishment of a corresponding relation between the ip and the home name, the configuration of information except the home name is not limited, and for example, the node information may further include public key information and the like.
The two nodes exchange node information to facilitate connection establishment and service switching.
(3) After receiving the node information fed back by the second node, taking the node information as opposite node information;
after receiving the correspondent node information, the correspondent node information can be written into the local hosts file, so that the correspondent node information can be read from the local hosts file for mutual handshake connection.
(4) And connecting to the second node according to the opposite node information.
The implementation of the inter-node connection according to the information of the corresponding node may refer to the description of the related art, and will not be described herein again.
In this embodiment, only the above implementation manner of information determination is described as an example, and other implementation manners may refer to the above description, which is not described herein again.
S102, monitoring the network states of the second node and the second node;
the network state may be determined according to the operation of the actual service, such as the failure of heartbeat packet transmission, or may be determined according to the operation state of the connected network device, such as the abnormality of the switch.
After the network state of the two nodes is determined, the respective network state information can be exchanged between the two nodes, so that the network state of the opposite node can be monitored, and the timely discovery and the timely service switching when the opposite network is abnormal can be further realized.
In order to promote the network state information to be timely acquired by the opposite node, the transmission of the network state information between the two nodes may be in the form of a heartbeat packet, and accordingly, the process of monitoring the network states of the second node and the second node may specifically include the following steps:
(1) monitoring the network state of the user to obtain network state information;
the monitoring of the network state itself may be determined by the transmission of the data packet and the operating state of the connected network device, and the implementation manner of monitoring the network state itself in this embodiment is not limited, and one implementation manner is as follows:
(1.1) monitoring the communication state of the gateway connected with the gateway;
(1.2) receiving the physical connection state of a physical network card connected with the network card;
and (1.3) determining the network state of the user according to the communication state and the physical connection state to obtain network state information.
The communication state of the monitoring gateway and the physical connection state of the physical network card are adopted in the evaluation mode of the network state, so that the network state of the node can be objectively evaluated from the perspective of physical line connection.
(2) Sending the network state information to the second node through the heartbeat packet;
(3) and receiving the network state information fed back by the second node as the network state of the second node.
The information transmission form of the heartbeat packet can ensure that the opposite terminal can know the network state of the local terminal in time, and meanwhile, the reverse monitoring of the network state can be further realized through frequent data transmission, for example, if the network state data sent by the opposite terminal node is still not received after the transmission time interval of the heartbeat packet is exceeded, the transmission of the network state data is proved to be abnormal.
In this embodiment, only the information transmission method is described as an example, and the above description can be referred to for the implementation of network status monitoring based on other transmission methods.
S103, judging whether the current node is a main configuration node or not; if yes, triggering step S104; if not, triggering step S105;
both nodes can be used as a main configuration node and a standby node, and in this embodiment, a corresponding main configuration node processing flow and a standby node processing flow are set for each node, so that flexible assignment of the main configuration node and the standby node is performed according to different use requirements.
One of the two nodes is set as a main configuration node, and the other is set as a standby node, it should be noted that the standby node may not be completely used as a standby of the main configuration node, and may also implement other service functions.
Judging whether the current node (namely the executed node itself, namely the first node) is a main configuration node; if yes, triggering step S104 to execute the corresponding process of the main configuration node; if not, triggering step S105 to execute the corresponding process of the standby node.
S104, enabling the network port, starting the cifs service according to the configuration, and sending the configuration to the second node so that the second node starts the service same as that of the first node according to the configuration;
if the self node is the main configuration node, the network port is enabled (allowing the input and output of signals), and at the moment, the client can be normally connected with the cifs service so as to start the cifs service according to the configuration, and simultaneously, the cifs configuration is sent to the opposite end node so as to facilitate the opposite end node to perform the same configuration after receiving the configuration information, thereby realizing the synchronous backup of the service.
S105, starting the cifs service, and triggering the corresponding cifs service according to the received configuration; and if the network state of the main configuration node is abnormal, enabling the network port and sending an arp packet of the gateway.
The non-main configuration node (namely the standby node) only starts the cifs service, and does not enable the network card configuration and directly respond to the user service while realizing the service. It should be noted that the two nodes map and mount the same iscsi volume, so as to implement the same service configuration.
In addition, two nodes send network state information to an opposite end node in the running process, the network state information (usually including basic detection information such as physical connection state, network quality and the like), if the network state of the active main configuration node is abnormal (for example, the service network is abnormal or the heartbeat does not respond), the standby node makes a virtual network card up and sends an ARP packet of the gateway, at the moment, the cifs service is successfully transferred (the ARP packet is a basic network protocol, and the purpose is mainly to actively refresh the configuration in the network), and the service switching of the main configuration node is realized.
It should be noted that, the processing mode of the main configuration node after the network state is abnormal is not limited in this embodiment, if the network state of the main configuration node is abnormal and recovered, the service recovery mechanism is also not limited in this embodiment, in order to avoid the processing burden of the standby node that is too heavy for a long time as much as possible, the standby node may close the network port (drop the network port) after receiving the notification of the network state recovery of the main configuration node, and the main configuration node refreshes the arp, so far, the cifs service of the main configuration node is recovered, and the standby node recovers the service standby state before the failure.
Based on the introduction, the technical scheme provided by the embodiment of the invention realizes common cifs system service backup through double nodes, the main configuration node opens a network port to respond to the cifs service request of the client, and the non-main configuration node starts the cifs service so as to conveniently backup the cifs service of the main configuration node and synchronize the service state; and monitoring the running state of the nodes in real time in the service process of the main configuration node, and if the network state of the main configuration node is abnormal, starting the network service to call the non-main configuration node to take over the cifs service. According to the method, the state of the two nodes is synchronized, and the state of the network of the other node is judged in real time, so that the backup transfer of the service is carried out, and the network port is opened, thereby providing high-availability data communication.
