Description
Technical Field
The invention relates to the technical field of distributed system clusters, in particular to a node access method and a node access system.
Background
Distributed service architectures are currently finding wider and wider application. Among them, ZooKeeper (reliable coordination system) is a distributed, open source distributed application coordination service. The ZooKeeper stores a metadata directory called znode, which carries real-time metadata of upper-layer services and tasks.
Under normal conditions, the information recorded in the znode is consistent with the actual conditions, so that the normal operation of the upper layer service and the task can be ensured. However, sometimes, because of the defect of the software product itself or the bad communication state between the component and the ZooKeeper, the information stored in the znode is inconsistent with the actual information of the task, which may cause the failure of starting the component instance. In a general method, a Hue logs in any node of a ZooKeeper cluster, and after performing correlation operation on a znode, a service with a fault is restarted, so that an upper-layer service re-registers the znode in the ZooKeeper, and then the upper-layer service is recovered.
However, the ZooKeeper cluster includes a plurality of nodes, and a Uniform Resource Locator (URL) address of one of the nodes can only be fixedly written in the configuration of the Hue, so that the Hue can only log in one fixed node in the ZooKeeper cluster. When the node fails, the znode cannot be normally accessed and managed by Hue.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present 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.
Fig. 1 is a schematic structural diagram of a node access system according to an embodiment of the present invention. As shown in fig. 1, the node access system provided in this embodiment may include: access means 11, forwarding means 12 and node cluster 13. The node cluster 13 includes a plurality of nodes, and the forwarding device 12 and the nodes both correspond to a same virtual Internet Protocol (IP) address.
And the access device 11 is used for acquiring the node access request and sending the node access request. And the destination IP address in the node access request is a virtual IP address. The node access request is for accessing a node in the node cluster 13.
And a forwarding device 12, configured to receive the node access request and send the node access request to a first node in the node cluster 13. The first node is a node with a normal access state.
Specifically, the node access system provided in this embodiment may include an access device 11, a forwarding device 12, and a node cluster 13. The node cluster 13 includes a plurality of nodes, and the physical IP address of each node is different, and the number of the nodes is not limited in this embodiment. The access means 11 and the forwarding means 12 correspond to physical entity devices, respectively. Optionally, in an implementation manner, the physical entity device corresponding to the access apparatus 11, the physical entity device corresponding to the forwarding apparatus 12, and each node in the cluster may be different physical entity devices. Optionally, in another implementation manner, the physical entity device corresponding to the access device 11 and a certain node in the cluster may be the same device.
In this embodiment, the forwarding device 12 and each node in the cluster correspond to the same virtual IP address. The access device 11 may obtain a node access request, where the node access request is used to access a node in the node cluster 13, and a destination IP address of the node access request is the above-mentioned virtual IP address. After acquiring the node access request, the access device 11 sends the node access request according to the virtual IP address. Accordingly, the forwarding device 12 may receive the node access request sent by the accessing device 11 corresponding to the virtual IP address, and send the node access request to the first node in the node cluster 13 with a normal access state. The first node may be any node in the node cluster 13 with a normal access state.
It can be seen that, in the node access system provided in this embodiment, the forwarding device and the nodes in the cluster both correspond to the same virtual IP address, and after the access device obtains the node access request, the access device sends the node access request by using the virtual IP address as a destination address, and the access device does not need to know or configure the forwarding device or a fixed node in the cluster in advance. The forwarding device receives the node access request sent by the access device, so that the node access request is sent to a node with a normal access state in the cluster, and even if a fault node exists in the node cluster, the node can be successfully accessed. In combination with a specific application scenario, when the node cluster is a ZooKeeper cluster, for an application scenario of accessing a node in the ZooKeeper cluster, in the node access system provided in this embodiment, the access device does not need to pre-configure a URL address of a certain node in the ZooKeeper cluster, and only needs to forward a node access request according to a virtual IP address corresponding to each node in the ZooKeeper cluster. In the prior art, only one pre-configured fixed ZooKeeper node can be accessed in a single node access mode, so that the problem that the node cannot be normally accessed when the pre-configured node fails exists. In this embodiment, any node in the node cluster with a normal access state can be accessed, so that the success rate of node access is improved. In addition, because a single fixed node does not need to be configured in advance, the complex operation flows of configuration modification and equipment restart caused by the failure of the node are avoided, and the node access efficiency is improved.
It should be noted that, in this embodiment, implementation manners of the physical devices and the node cluster 13 corresponding to the access device 11 and the forwarding device 12 are not limited, and the method is applicable to application scenarios for solving a single node access manner.
Optionally, the access device 11 may integrate a Hue service, the forwarding device 12 may integrate a Keepalived service, and the node cluster 13 is a ZooKeeper cluster. The Hue is an open-source Apache Hadoop UI system, and can interact with a node cluster on a World Wide Web (Web) console of a browser end by using the Hue, so that related data is analyzed and processed. The Keepalived service may detect the state of the server. Specifically, if one web server is down or fails, Keepalived detects the web server, removes the failed server from the system, and replaces the server with other servers; when the failed server works normally, Keepalived can automatically add the server to the server group.
Optionally, the forwarding device 12 is specifically configured to:
and determining a first node in the node cluster 13 according to a preset scheduling policy and the access state of each node in the node cluster 13.
And sending a node access request to the first node according to the physical IP address of the first node. The forwarding device 12 stores a physical IP address of each node in the node cluster 13.
Optionally, the preset scheduling policy may include, but is not limited to, at least one of the following: round robin scheduling and priority scheduling.
This is illustrated by way of example.
Optionally, in an example, the preset scheduling policy is polling scheduling. The node cluster comprises 4 nodes which are respectively 1-4 nodes. Suppose that the access states of the nodes 1-2 are abnormal and the access states of the nodes 3-4 are normal. The forwarding device can be in a polling scheduling sequence of nodes 1-4 according to a polling scheduling strategy. However, due to the abnormal access state of the nodes 1-2, the forwarding device may determine that the first node is the node 3, and send a node access request to the node 3 according to the physical IP address of the node 3, thereby realizing successful access to the node in the node cluster.
Optionally, in another example, the preset scheduling policy is priority scheduling. The node cluster comprises 4 nodes which are respectively 1-4 nodes. Suppose that the scheduling priorities of the nodes are as follows from high to low: node 1, node 4, node 2 and node 3. The access states of the nodes 1-2 are abnormal, and the access states of the nodes 3-4 are normal. The forwarding device can determine that the first node is the node 4 according to the priority scheduling policy, and sends a node access request to the node 4 according to the physical IP address of the node 4, so that the node in the node cluster can be successfully accessed.
It should be noted that, in this embodiment, a method for the forwarding device 12 to obtain the access state of each node in the node cluster 13 is not limited. For example, the access state of the acquisition node is detected through heartbeat. In heartbeat detection, a sender may send a heartbeat signal to a receiver. The heartbeat signal refers to a data packet transmitted periodically. The sender can judge the state of the receiver or judge whether the communication link between the sender and the receiver is disconnected according to the reply condition of the receiver.
Optionally, the forwarding device 12 may include at least two forwarding sub-devices, and the priorities of the at least two forwarding sub-devices are different.
And the first forwarding sub-device is used for receiving the node access request and sending the node access request to the first node. The first forwarding sub-device is the forwarding sub-device with the highest priority in the forwarding sub-devices with normal states.
In this embodiment, the number of forwarding sub-devices is not limited.
This is illustrated by way of example.
Suppose that the forwarding device includes two forwarding sub-devices, which are the forwarding sub-devices 1-2 respectively. The forwarding sub-apparatus 1 has a higher priority than the forwarding sub-apparatus 2. Currently, if the state of the forwarding sub-device 1 is abnormal and the state of the forwarding sub-device 2 is normal, the first forwarding sub-device is the forwarding sub-device 2. The forwarding sub-apparatus 2 may receive the node access request sent by the access apparatus and send the node access request to the first node in the node cluster. And the node accesses the request. Optionally, if the state change of the subsequent forwarding sub-device 1 is normal, the first forwarding sub-device is changed to the forwarding sub-device 1.

The embodiment provides a specific application scenario of the node access system based on the embodiment shown in fig. 1. In this embodiment, the access device integrates a Hue service, the forwarding device integrates a Keepalived service, and the node cluster is a ZooKeeper cluster.

The ZooKeeper cluster includes 3 nodes, referred to as node 1 to node 3, respectively. The device names, physical IP addresses, and corresponding virtual IP addresses of the active device, the standby device, and the nodes 1 to 3 may be referred to in table 1.
