Exemplary method
The present embodiment provides a cloud-based VPN server switching method, specifically as shown in fig. 1, the method includes:
step S100, establishing communication between a first VPN server and a second VPN server, and configuring the first VPN server as an active server.
In order to avoid that the VPN server has a problem and the application cannot run, in this embodiment, two VPN servers, that is, a first VPN server and a second VPN server, are applied to a cloud service provider, and both the first VPN server and the second VPN server are installed with VPN server software and an application program that supports switching between a main server and a standby server. In the operation process, firstly, communication between the first VPN server and the second VPN server is established, the first VPN server is configured as an active server, and the second VPN server is a standby server. In this embodiment, two VPN servers are set, and one of the VPN servers is configured as a primary server, so that when the primary server fails, the primary server can be switched to another VPN server, thereby ensuring normal operation of an application program and improving user experience.
In a specific embodiment, as shown in fig. 2, the step of establishing communication between the first VPN server and the second VPN server in step S100 includes:
step S110, a first internal private IP address and a second internal private IP address are obtained;
step S120, allocating the first internal private IP address to a first internet access corresponding to the first VPN server, and allocating the second internal private IP address to a second internet access corresponding to the second VPN server.
The first internet access and the second internet access are used for private communication between the first VPN server and the second VPN server, in this embodiment, a first internal private IP address and a second internal private IP address are preset, when communication between the first VPN server and the second VPN server is established, the first internal private IP address and the second internal private IP address are obtained, the first internal private IP address is allocated to a first internet access corresponding to the first VPN server, the second internal private IP address is allocated to a second internet access corresponding to the second VPN server, and after the internal private IP addresses are allocated to the first internet access and the second internet access, the first VPN server and the second VPN server can perform real-time communication through the first internet access and the second internet access configured with the internal private IP addresses. For example, the first internal private IP address is 192.168.100.1, the second internal private IP address is 192.168.100.2, and when communication between the first VPN server and the second VPN server is established, 192.168.100.1 is allocated to the first portal, and 192.168.100.2 is allocated to the second portal.
In a specific embodiment, as shown in fig. 3, the step of configuring the first VPN server as an active server in step S100 includes:
step S130, obtaining an external public network address;
step S140, allocating the external public network address to a third network port corresponding to the first VPN server, so as to configure the first VPN server as an active server.
Specifically, an external public network address is preset in this embodiment, the external public network address is used for the VPN server to communicate with each terminal of the internet of things, and the first VPN server is further provided with a third internet access for communicating with each terminal of the internet of things. When the first VPN server is configured as a primary server, an external public network address is firstly obtained, and then the external public network address is distributed to a third network port corresponding to the first VPN server. And the third internet access is an external internet access of the first VPN server, and after the external public network address is distributed to the third network, each internet of things terminal establishes connection with the first VPN server through VPN dialing. For example, the external public network address is 10.10.88.99, and after 10.10.88.99 is allocated to the third internet access, the connection between the camera and the mobile phone APP and the first VPN server can be established through VPN dialing.
In a specific embodiment, after the step of configuring the first VPN server as the active server in step S100, the step includes:
step S150, controlling the first VPN server to receive an access request and send data corresponding to the access request through the external public network address.
In the foregoing step, after the external public network address is allocated to the third port corresponding to the first VPN server, each internet of things terminal may establish a connection with the first VPN server through VPN dialing. After the internet of things terminals are connected with the first VPN server, each internet of things terminal can send an access request to the first VPN server and receive data corresponding to the access request returned by the first VPN server, and the first VPN server can also receive the access request sent by the internet of things terminals and send the data corresponding to the access request to the internet of things terminals. For example, after the camera and the mobile phone APP can establish connection with the first VPN server through VPN dialing, the camera can store video data acquired by the camera to a cloud end, the mobile phone APP requests the cloud end for the video data acquired by the camera, and the cloud end receives an access request of the mobile phone APP through the first VPN server and sends the video data acquired by the camera to the mobile phone.
In a specific embodiment, after the step of configuring the first VPN server as the active server in step S100, the method further includes:
step S160, controlling the first VPN server to send the access request and the data corresponding to the access request to the second VPN server through the first internal private IP address.
In order to continue to receive an access request and send data corresponding to the access request through a second VPN server after a failure occurs in a first VPN server, in this embodiment, while controlling the first VPN server to receive the access request and send the data corresponding to the access request through the external public network address, the first VPN server is also controlled to send the access request and the data corresponding to the access request to the second VPN server through the first internal private IP address in real time, so that when the first VPN server fails, the second VPN server can continue to receive the access request and send the data corresponding to the access request.
Step S200, monitoring the communication state between the first VPN server and the second VPN server in real time through the heartbeat message sent between the first VPN server and the second VPN server.
In order to monitor whether the first VPN server, i.e., the primary server, fails in real time, in this embodiment, a heartbeat-plus-measurement mechanism is used to monitor a communication state between the first VPN server and the second VPN server in real time, and after communication between the first VPN server and the second VPN server is established, the first VPN server and the second VPN server mutually send heartbeat messages through the first network port and the second network port. The communication state between the first VPN server and the second VPN server can be monitored in real time through heartbeat messages sent between the first VPN server and the second VPN server. For example, when the first VPN server does not receive a heartbeat message sent by the second VPN server within a preset time, it is described that the second VPN server has a problem; when the second VPN server does not receive the heartbeat message sent by the first VPN server within the preset time, the first VPN server is proved to have a problem.
Step 300, when it is not monitored that the first VPN server sends a heartbeat message to the second VPN server within a preset time, switching the second VPN server to be the primary server.
Specifically, in this embodiment, when it is not monitored that the first VPN server sends a heartbeat packet to the second VPN server within a preset time, it is considered that the first VPN server fails, and at this time, the first VPN server, as a master server, cannot receive an access request sent by each internet of things terminal and send data corresponding to the access request, so that the second VPN server is switched to a master server, and the second VPN server receives the access request and sends the data corresponding to the access request continuously, so that normal operation of an application program is ensured, and user experience is improved. In a specific embodiment, the first VPN server and the second VPN server are configured to send heartbeat messages to each other every 1 second, and when it is not monitored for 3 consecutive times that the first VPN server sends heartbeat messages to the second VPN server, that is, when it is not monitored that the first VPN server sends heartbeat messages to the second VPN server within 3 consecutive seconds, it is considered that the first VPN server fails.
In a specific embodiment, as shown in fig. 4, the step of switching the second VPN server to the active server in step S300 includes:
step S310, removing the binding relation between the third internet access and the external public network address;
step S320, allocating the external public network address to a fourth network port corresponding to the second VPN server, so as to switch the second VPN server to the active server.
Specifically, the fourth network port is an external network port corresponding to the second VPN server, and when it is not monitored that the first VPN server sends a heartbeat packet to the second VPN server within a preset time, the binding relationship between the third network port and the external public network address is released, and the external public network address is allocated to the fourth network port, that is, the primary server is switched from the first VPN server to the second VPN server. For example, the external public network address is 10.10.88.99, and when it is not detected that the first VPN server sends the heartbeat message to the second VPN server within the preset time, the binding relationship between the third network port and the 10.10.88.99 is released, and 10.10.88.99 is allocated to the fourth network port.
In a specific embodiment, after step S310, the method further includes:
step S330, controlling the second VPN server to receive an access request and send data corresponding to the access request through the external public network address.
After the external public network address is distributed to the fourth internet access corresponding to the second VPN server, the connection between each Internet of things terminal and the first VPN server is interrupted due to time-out, and the connection between each Internet of things terminal and the second VPN server can be established by carrying out VPN dialing again. After the internet of things terminals are connected with the second VPN server, each internet of things terminal can send an access request to the second VPN server and receive data corresponding to the access request returned by the second VPN server, and the second VPN server can also receive the access request sent by the internet of things terminal and send the data corresponding to the access request to the internet of things terminal. For example, after the first VPN server fails, the connection between the camera and the first VPN server and the connection between the mobile phone APP and the first VPN server may be interrupted due to time out, after the connection between the camera and the second VPN server is established through VPN dialing, the camera may continue to store the acquired video data to the cloud through the second VPN server, and the mobile phone APP may continue to access the video data acquired by the camera through the second VPN server.
In a specific embodiment, after the step of switching the second VPN server to the active server in step S300, the method includes:
step M310, establishing communication between the second VPN server and a third VPN server;
step M320, monitoring a communication state between the second VPN server and the third VPN server in real time through the heartbeat packet sent between the second VPN server and the third VPN server.
In order to avoid interruption of the application program caused by a failure of the second VPN server, in this embodiment, after the second VPN server is configured as the active server, communication between the second VPN server and the third VPN server is further established, which includes the steps of removing the binding relationship between the first internet access and the first internal private IP address, and allocating the first internal private IP address to a fifth internet access corresponding to the third VPN server. After communication between the second VPN server and the third VPN server is established, the communication state between the second VPN server and the third VPN server is monitored in real time through a heartbeat message sent between the second VPN server and the third VPN server, and when the heartbeat message sent from the second VPN server to the third VPN server is not monitored within a preset time, the third VPN server is switched to be the active server, where a method for switching the third VPN server to be the active server is similar to the aforementioned method for switching the second VPN server to be the active server, that is, the external public network address is allocated to a sixth network port corresponding to the third VPN server.
It can be seen that embodiments of the present invention first establish communication between a first VPN server and a second VPN server. And then, configuring the first VPN server as an active server. And then, monitoring the communication state between the first VPN server and the second VPN server in real time through a heartbeat message sent between the first VPN server and the second VPN server. And finally, when the heartbeat message sent by the first VPN server to the second VPN server is not monitored within the preset time, the second VPN server is switched to the primary server, so that the second VPN server is switched to the primary server by setting the first VPN server and the second VPN server and setting the first VPN server as the primary server when the first VPN server fails, the situation that the application cannot be used when the primary server fails is avoided, and user experience is improved.
