Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
To avoid that ports allocated to the proxy service are occupied, the proxy service cannot operate normally. The ports of the service system where the proxy service is located can be monitored through a third party service independent of the proxy service, the obtained port information is sent to another service different from the proxy service and the third party service, and the other service allocates ports for the proxy service according to the port information.
However, this method requires a special third party service to monitor each port, and multiple services interact to implement the process of allocating ports, which makes the system structure complex, and thus the system maintenance complex.
The embodiment of the invention provides a port allocation method, a system, a device, equipment and a storage medium, which are used for solving the problem that proxy service cannot normally operate due to the fact that the port allocated to the proxy service is occupied. In the embodiment of the invention, the proxy service reports the port information to the management service, and a third party service independent of the proxy service is not required to monitor each port, so that the complexity of a system structure can be reduced, and further the complexity of system maintenance, the cost of system maintenance, the difficulty of system development and the like can be reduced.
An embodiment of the present invention provides a port allocation system, as shown in fig. 1, may include:
a proxy service 101 and a management service 102;
the proxy service 101 acquires port information of a service system where the proxy service 101 is located, and reports the port information to the management service 102;
the management service 102 receives the port information and allocates an unoccupied port to the proxy service 101 according to the port information.
In the embodiment of the invention, the proxy service 101 acquires port information of a service system where the proxy service 101 is located, and reports the port information to the management service 102; the management service 102 may assign the agent service 101 with unoccupied ports according to the port information. In this way, the occupied ports can be prevented from being allocated to the proxy service, and the problem that the proxy service 101 cannot normally operate due to the occupied ports allocated to the proxy service can be solved.
In the embodiment of the invention, the proxy service actively reports the port information to the management service, and a third party service independent of the proxy service is not required to monitor each port, so that the complexity of a system structure can be reduced, and further the complexity of system maintenance, the cost of system maintenance, the difficulty of system development and the like can be reduced.
The proxy service can monitor each port in the service system where the proxy service is located, and obtain the port information of each port. The port information is used for indicating the unoccupied port in the service system, namely, the management service can obtain the unoccupied port in the service system according to the port information and allocate the unoccupied port for the proxy service. For example, the port information may include information of an unoccupied port, and then the unoccupied port may be obtained according to the port information; or the port information may include the information of the occupied ports, the occupied ports are obtained according to the port information, and the occupied ports are removed from all ports in the service system, namely the unoccupied ports. In one implementation, the port information may include occupancy information, and the occupancy information for each port may include whether each port has been occupied or unoccupied. The agent service reports the port information to the management service, the management service can obtain the occupied port and the unoccupied port according to the occupation condition information of each port, and the unoccupied port can be allocated for the agent service according to the port information.
The allocation of ports for proxy services can be understood as follows: ports are allocated for clients accessing proxy services. If the proxy service receives an access request sent by the user terminal, port information can be sent to the management service to request the management service to allocate a port, and after the management service is a proxy service port, the proxy service can forward the access request sent by the user terminal to the service node by using the allocated port, and the service node processes the access request.
The service system in which the proxy service is located may be a system that deploys a plurality of services including the proxy service. The service system may include one machine or may include multiple machines deployed in a distributed manner. The machine may be an entity device, software, or the like. The ports of the service system may include ports of individual machines in the service system.
In the embodiment of the invention, the proxy service and the management service can be deployed on the same device in the service system. Alternatively, the proxy service and the management service may be deployed on different devices, e.g., the proxy service may be deployed on a proxy device and the management service may be deployed on a management device.
In an alternative embodiment, before the proxy service reports the port information to the management service, the method may further include:
Adding configuration information in the proxy service, wherein the configuration information comprises a service address of the management service; the port information is sent to the service address.
It is also understood that the proxy service registers the service address of the management service. The service address may be a network protocol (Internet Protocol, IP) address, port address, etc.
Specifically, configuration information "report_server_info= [ ]" may be added to the configuration of the proxy service, and the configuration information indicates a service address of the management service, that is, an address of the proxy service reporting port information.
Thus, the proxy service obtains the port information and can report the port information to the service address indicated by the configuration information.
Here, "ports= [ ]" or the like may be transmitted in json format, and port information of each port is represented.
In one implementation, the proxy service may also pre-configure a preset time interval for acquiring port information and a preset time interval for reporting port information, for example, add configuration information "report_interval" in the configuration of the proxy service to indicate the preset time interval.
In an alternative embodiment, the proxy service may include a first thread and a second thread, the first thread configured to obtain port information; the second thread is used for reporting port information to the management service.
The proxy service can acquire port information of a service system where the proxy service is located through a preset system command.
The first thread can scan each port in the system at regular time according to a preset time interval, and acquire port information of a service system where the proxy service is located through a preset system command.
For example, the command may be: netstat-tln |awk' BEGIN { count=0 } { ++count; if (count > 2) print $4}, obtain port information.
The second thread may also report port information to the management service at preset time intervals. The second thread may be synchronous or asynchronous with the first thread, e.g., the predetermined time interval used by the first thread may be the same as or different from the predetermined time interval used by the second thread.
In one implementation, the proxy service may further include: and a cache module.
The first thread acquires port information according to a first time interval and stores the acquired port information to the cache module;
and the second thread acquires port information from the cache module according to a second time interval and reports the port information to the management service.
The first time interval and the second time interval may be determined according to actual requirements, such as 5 seconds, 10 seconds, etc. In one implementation, the first time interval and the second time interval are different.
Therefore, the problem of coupling between the two threads can be solved through the cache module, decoupling of the first thread and the second thread is achieved, and port information can be obtained through an asynchronous thread mechanism.
In an alternative embodiment, the management service may select a port from the unoccupied ports according to a preset allocation policy, and allocate the selected port to the proxy service.
The preset allocation policy may include allocation according to occupancy of each machine port in the service system.
Specifically, according to the load condition of each machine in the service system and/or the ports designated by the user, the ports are selected from unoccupied ports, and the selected ports are allocated to the proxy service.
In one implementation, the preset allocation policy may include allocation according to load conditions of each machine in the service system in a load balancing manner.
In another implementation manner, multiple machines in the service system may each deploy a proxy service, for example, machine 1, machine 2, and machine 3 each deploy a proxy service, where machine 1, machine 2, and machine 3 are in a master-slave relationship, and as one machine is the master machine at a time, other slave machines are used as standby machines of the master machine to achieve high availability. The agent service of each machine in the system reports the port information obtained by monitoring to the management service, and the management service gathers the port information respectively reported by each agent service, for example, analyzes the port information reported by each agent service to obtain unoccupied ports indicated by each port information.
In another implementation, the preset allocation policy may further include allocating according to a user-specified port. The ports can be allocated in combination with the use of each port and user-specified ports. For example, if the port range specified by the user is 30000-50000, selecting a port within the range 30000-50000 from the unoccupied ports obtained according to the port information, and taking the port within the range as the port to be allocated to the proxy service.
In one implementation, the allocation can be performed according to the serial number sequence of the ports, and meanwhile, each allocation condition can be recorded, so that the allocation efficiency can be improved.
In another implementation, the port assignment may be combined with the load condition of each machine in the service system and the user-specified port assignment. For example, after unoccupied ports are selected in a load-balanced manner according to the load conditions of the respective machines, ports within a user-specified port range are selected from among the selected ports as ports allocated to proxy services, such as ports within the range 30000-50000.
In the distributed database, the service is deployed through the master-standby mode, and in the case of deploying the service through the master-standby mode, there is a need for a primary-standby switch, for example, a standby node switches to provide services for the primary node. In the process of realizing the active-standby switching, the active-standby switching can be realized by using the proxy service in a load balancing mode, so that a user can access the active node.
In particular, the proxy service may be implemented by proxy component Haproxy, neutron or nmginx. While Haproxy, neutron or nmginx have port occupancy problems. For example, if a port assigned to nmginx is occupied, the port is not valid and cannot be loaded normally; if the ports allocated to the Neutron are occupied, port conflicts are generated and error information is returned; if the ports assigned to the Haproxy are occupied, the Haproxy cannot be started, which affects load balancing in the service system where the Haproxy is located, and similarly, other proxy components have the same port occupation problem. Where a port is occupied may be understood as having been used by other services in the service system.
In order to avoid that the ports allocated to the proxy service in the distributed database are occupied, which causes that the proxy service cannot operate normally, affects system load balancing, etc., the proxy service in the embodiment of the invention may include Haproxy, neutron or nmginx, etc.
The port distribution system provided by the embodiment of the invention can be applied to a distributed database, and well operates in the distributed database.
In a specific embodiment, the proxy service is implemented by a proxy component Haproxy. The Haproxy acquires port information of each port in a service system where the Haproxy is located, such as occupation condition information of each port, and reports the port information to a management service, such as a network distribution service (trove-lb).
Specifically, configuration information report_server_info= [ ] is added in the Haproxy configuration to represent the service address to be reported by Haproxy, namely the service address of the management service trove-lb. It is also understood that Haproxy registers the service address of the management service.
Meanwhile, a preset time interval for acquiring port information and a preset time interval for reporting port information can be preset, for example, configuration information 'report_interval' is added in the configuration of Haproxy to represent the preset time interval. The preset time interval for acquiring the port information and the preset time interval for reporting the port information may be the same or different.
Two threads, thread 1 and thread 2, and a cache module cache may be initialized. Haproxy starts thread 1, acquires port information according to a first time interval through thread 1, and stores the acquired port information to a cache. Haproxy starts thread 2, obtains port information from the cache according to a second time interval through thread 2, and reports the port information to the trove-lb.
the control-lb receives port information reported by Haproxy; and assigning unoccupied ports to the Haproxy according to the port information.
Specifically, the trove-lb obtains unoccupied ports in the service system according to the occupation condition information of each port in the service system; selecting ports from unoccupied ports according to a preset allocation strategy, and allocating the selected ports to Haproxy. For example, trove-lb gathers port information reported by each Haproxy, for example, analyzes port information reported by each Haproxy to obtain unoccupied ports indicated by each port information.
In one approach, the assignment may be made in connection with a user-specified port. For example, if the range of the port specified by the user is 30000-50000, the Haproxy sends the scanned available port to the trove-lb, the trove-lb only selects the available port between 30000-50000 when allocated, if 30001 is already occupied, the user can allocate 30002 to the Haproxy, specifically, the user terminal accessing the Haproxy can be allocated, and meanwhile, the trove-lb can save the already allocated port in the loadbandwidth.
In addition, in order to improve the allocation efficiency, the allocation may be performed according to the serial number sequence of the ports, for example, the ports are selected from the unoccupied ports to perform the allocation in a sequential scanning manner, and meanwhile, the allocation condition of each time may also be recorded. For example, the current allocation port 30002 is recorded, and then the port may be selected from 30003 for allocation next time.
In this way, the Haproxy actively reports port information to the trove-lb, the port information can include the service condition of each port, an unoccupied port can be obtained according to the port information, and the port can be understood as an available port, so that the function of actively reporting the available port can be realized. the trove-lb allocates ports to the Haproxy according to the port information, namely allocates unoccupied ports to the Haproxy, so that the problem that the Haproxy cannot normally operate due to the fact that the occupied ports are allocated to the Haproxy can be solved.
Moreover, the Haproxy actively reports port information to the management service, and the ports do not need to be monitored by using a service independent of Haproxy and other third parties, so that the number of system components can be reduced, namely the complexity of a system structure can be reduced, the complexity of system maintenance can be further reduced, the cost of system maintenance, the difficulty of system development and the like are reduced, and the development and maintenance are facilitated.
