Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application 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 present application and are not intended to limit the present application.
The gateway of the internet of things is also a router in nature, and not only has the network routing function of a civil router, but also has the function of connecting the devices of the internet of things (such as Bluetooth devices, zigBee devices and the like) to the internet.
In addition, different from a civil router, in the internet of things gateway industry, the number of deployed gateways is often more than one, and therefore, the gateways of the internet of things need to handle the cascade relationship among multiple gateways.
At present, there are two main ways of cascading between gateways, a bridge mode and a non-bridge mode.
When the gateways are cascaded in a bridging mode, the newly added gateway does not add a network segment but continues the network segment of the upstream network, namely, the upstream network can communicate with the downstream network, and the batch management of the Internet of things equipment is favorably realized.
For example, as shown in fig. 1, after the gateways are cascaded in the bridge mode, the IP addresses of the WAN interfaces of the gateway 1 and the gateway 2 are 192.168.0.2 and 192.168.0.3, and the IP address of the WAN interface of the newly added gateway 3 is configured to be 192.168.0.4; namely, the gateway 1, the gateway 2 and the newly added gateway 3 are in the same network segment, and the upstream network can communicate with the downstream network, which is beneficial to realizing the batch management of the internet of things devices.
When the gateways are cascaded in a non-bridging mode, each time a gateway is added, a network segment is added in the internet of things system, and after the network segment is added, an upstream network cannot directly access a downstream network.
For example, as shown in fig. 2, the IP addresses of the WAN interfaces of the gateway 1 and the gateway 2 are 192.168.0.2, 192.168.98.2, and the IP address of the WAN interface of the newly added gateway 3 is configured to be 192.168.97.2; the gateway 1, the gateway 2 and the gateway 3 are all in different network segments, and an upstream network cannot directly access a downstream network, so that the method has the characteristic of higher network security.
However, in practical applications, when the gateways are deployed, the gateways that are cascaded in the bridge mode are adopted, and in order to better manage the gateways, a static IP address needs to be manually set for each gateway in sequence; however, in the gateways that are cascaded in the non-bridging mode, because each gateway needs to be located in a different network segment, an IP address needs to be manually set for each gateway in sequence, that is, the two gateways are cascaded in a manner that the IP addresses of the gateways need to be manually set, and plug and play cannot be realized.
Based on this, embodiments of the present application provide a method and an apparatus for configuring a gateway IP address, a gateway, and a readable storage medium, which can implement automatic configuration of a gateway IP address, achieve an effect of plug and play, and simplify deployment of a gateway.
Fig. 3 is a schematic view illustrating an implementation flow of a method for configuring an IP address of a gateway according to an embodiment of the present application, where the method for configuring an IP address of a gateway is applied to the gateway, and after the gateway is powered on, a device for configuring an IP address of the gateway can execute the method for configuring an IP address of a gateway. Specifically, the method for configuring the gateway IP address may include: step 101 to step 103 are detailed as follows:
In this embodiment, the cascading manner between the gateways may include a bridge mode and a non-bridge mode.
Optionally, the cascade mode of the detection gateway may be implemented by: detecting whether a mode switch of the gateway is turned on, and confirming that a cascade mode of the gateway is a bridge mode or a non-bridge mode when the mode switch of the gateway is turned on; and when the mode switch of the gateway is closed, determining that the cascade mode of the gateway is a non-bridge mode or a bridge mode. Or acquiring factory setting information of the gateway and confirming the cascade mode of the gateway.
It should be noted that, this is merely an example for detecting the cascading mode of the gateway, and is not meant to limit the scope of the present application, and in other embodiments of the present application, the cascading mode of the gateway may be detected in other manners.
And 102, configuring the bridge service, the DHCP service and the switch state of the firewall of the gateway into a preset switch state according to the cascade mode, and detecting whether the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs when the bridge service and the DHCP service of the gateway are in the preset switch state.
Optionally, the configuring, according to the cascade mode, the bridge service of the gateway, the DHCP service, and the switch state of the firewall to the preset switch state may include: if the cascade mode of the gateway is a bridge mode, configuring the bridge service of the gateway to be in an open state, and configuring the DHCP service and the firewall of the gateway to be in a closed state; and if the cascade mode of the gateway is a non-bridge mode, configuring the bridge service of the gateway to be in a closed state, and configuring the DHCP service and the firewall of the gateway to be in an open state.
That is, when the cascade mode of the gateway is the bridge mode, the preset switch states corresponding to the bridge service, the DHCP service and the firewall are that the bridge service is in the on state, and the DHCP service and the firewall are in the off state; when the cascade mode of the gateway is a non-bridge mode, the preset switch states corresponding to the bridge service, the DHCP service and the firewall are that the bridge service is in a closed state, and the DHCP service and the firewall are in an open state.
Specifically, in the embodiment of the present application, when the cascade mode of the gateway is the bridge mode, the newly added gateway does not add a network segment but continues the network segment of the upstream network, so that when the cascade mode of the gateway is the bridge mode, the bridge service is in an open state, and the DHCP service and the firewall are in a closed state, so that the newly added gateway and the downstream device thereof can obtain the DHCP service from the upstream gateway or router, and the firewall of the downstream device of the newly added gateway is in the same state as that in a local area network.
For example, as shown in fig. 1, when accessing the internet of things, the newly added gateway 3 may send an IP address acquisition request to the upstream network, and receive the IP address 192.168.0.4 of the WAN interface of the gateway 3 forwarded by the gateway 1 and the gateway 2 and allocated by the router 4 of the upstream network, where the gateway 1 and the gateway 2 only forward the IP address and do not allocate the IP address.
In addition, when the cascade mode of the gateway is a non-bridge mode, a network segment is added to the newly added gateway instead of the network segment of the continuous upstream network, that is, the IP address of the newly added gateway is not in the same network segment with the IP addresses of other gateways and routers in the upstream, so that when the cascade mode of the gateway is the non-bridge mode, the bridge service is in a closed state, and the DHCP service and the firewall are in an open state, so that the downstream equipment of the newly added gateway can obtain the DHCP service from the newly added gateway, and the firewall of the newly added gateway can protect the downstream Internet of things equipment.
For example, as shown in fig. 2, the gateway 2 and the gateway 3 are cascaded in a non-bridge mode, and when the new gateway 3 accesses the internet of things, the IP address 192.168.97.2 of the WAN interface can be obtained from the DHCP service of the gateway 2 of the upstream network, and at this time, the IP address 192.168.98.2 of the WAN interface of the gateway 2 and the IP address 192.168.97.2 of the WAN interface of the gateway 3 are in different network segments.
In the embodiment of the application, after the gateway acquires the DHCP service from an upstream gateway or router and obtains the IP address of the WAN interface, it is necessary to detect whether the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs, so as to avoid the collision of the gateway IP addresses and the abnormality of the network of the gateway itself.
And 103, if the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs, modifying the IP address of the gateway LAN interface until the network segment to which the IP address of the gateway LAN interface belongs is inconsistent with the network segment to which the IP address of the gateway WAN interface belongs, and finishing the configuration of the gateway IP address.
In practical application, the default IP address of the LAN interface when the gateway leaves the factory is generally 192.168.98.1, and therefore, when the gateway accesses the internet of things, and after the IP address of the WAN interface is acquired from an upstream gateway or router, the IP address of the WAN interface acquired from the upstream gateway or router may be located in a network segment with the IP address of the default LAN interface when leaving the factory, and therefore, it is necessary to detect whether the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs, and modify the IP address of the gateway LAN interface when the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs, so as to avoid conflict between the IP addresses of the gateway and cause abnormality of the network of the gateway itself.
For example, as shown in fig. 2, the IP address of the WAN interface acquired by the gateway 2 from the DHCP service of the gateway 1 is 192.168.98.2, and the default IP address of the LAN interface when the gateway 2 leaves the factory is 192.168.98.1, at this time, the gateway 2 and the gateway 1 are in a network segment, and therefore, the IP address of the LAN interface of the gateway 2 needs to be modified to make the network segment to which the IP address of the LAN interface of the gateway 2 belongs coincide with the network segment to which the IP address of the WAN interface of the gateway 2 belongs, so as to avoid the collision of the IP addresses of the gateway 2 and the abnormality of the network of the gateway 2 itself.
Optionally, in some embodiments of the present application, the modifying the IP address of the gateway LAN interface may be implemented by a circular decrement or a circular increment.
For example, the IP address of the gateway LAN interface is 192.168.X.1, and x ranges from 0 to 255, and when the network segment to which the IP address of the gateway LAN interface belongs is identical to the network segment to which the IP address of the gateway WAN interface belongs, the value of x may be reduced by 1 until the network segment to which the IP address of the gateway LAN interface belongs is not identical to the network segment to which the IP address of the gateway WAN interface belongs, and the configuration of the gateway IP address is completed. Wherein, when x is zero, x minus 1 is 255.
Since the correspondence between the IP address of the gateway LAN interface and the domain name of the gateway is changed after the IP address of the gateway LAN interface is modified, in order to ensure that the gateway can be accessed by using the domain name of the gateway, after the IP address of the gateway LAN interface is modified, the modified IP address of the gateway LAN interface may be written into a preset storage path of the gateway, for example, into an/etc/hosts file, so as to update the correspondence between the IP address of the gateway LAN interface and the domain name of the gateway.
Optionally, in some embodiments of the present application, before detecting whether the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs in step 102, it may be detected whether the IP address of the gateway WAN interface is empty; and when the IP address of the gateway WAN interface is empty, outputting a prompt message that the upstream network of the gateway is abnormal. And when the IP address of the gateway WAN interface is not empty, detecting whether the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs.
Specifically, after the gateway accesses the internet of things, the gateway can request to allocate an IP address of a WAN interface to an upstream network, so that when the IP address of the WAN interface is empty, it indicates that the upstream network of the gateway is abnormal, and the IP address of the WAN interface cannot be allocated to the gateway, and therefore, a prompt message indicating that the upstream network of the gateway is abnormal can be output without detecting whether a network segment to which the IP address of the LAN interface of the gateway belongs is consistent with a network segment to which the IP address of the WAN interface of the gateway belongs.
Optionally, after the notification message that the upstream network of the gateway is abnormal is output, or when the gateway does not complete the configuration of the IP address due to other reasons, the gateway may be controlled to enter the sleep state first, and after a first preset time interval, the gateway is awakened, and the IP address is configured for the gateway again.
The first preset duration may be set according to actual experience, or may be set by default when leaving a factory.
When the cascade mode of the gateway is the bridge mode, the bridge service is in an open state, and in order to ensure that the bridge mode of the gateway can work normally, optionally, when the IP address of the gateway WAN interface is detected not to be empty, whether the IP address of the gateway WAN interface is consistent with the IP address configured in the bridge service of the gateway can be detected; and when the IP address of the gateway WAN interface is inconsistent with the IP address configured in the bridging service of the gateway, updating the IP address configured in the bridging service of the gateway into the IP address of the gateway WAN interface so as to ensure that the bridging mode of the gateway can work normally.
In some embodiments of the present application, after the configuration of the IP address of the gateway is completed, the gateway may be further controlled to enter a sleep state, and after a second preset time interval, the gateway is awakened again, and the IP address of the gateway is configured.
In the embodiment of the application, after the gateway is started, a cascade mode of the gateway is detected, then, a bridge service, a DHCP service and a switch state of a firewall of the gateway are configured to be a preset switch state according to the cascade mode, and whether a network segment to which an IP address of a gateway LAN interface belongs is consistent with a network segment to which an IP address of a gateway WAN interface belongs is detected when the bridge service and the DHCP service of the gateway are in the preset switch state; and when the network segment to which the IP address of the gateway LAN interface belongs is consistent with the network segment to which the IP address of the gateway WAN interface belongs, modifying the IP address of the gateway LAN interface until the network segment to which the IP address of the gateway LAN interface belongs is inconsistent with the network segment to which the IP address of the gateway WAN interface belongs, completing the configuration of the gateway IP address, realizing the automatic configuration of the gateway IP address, achieving the plug-and-play effect, avoiding the need of manually setting the gateway IP address, simplifying the deployment of the gateway, and greatly improving the deployment efficiency of the gateway especially when the number of the gateway is large.
In addition, the IP address and the domain name of the gateway LAN interface are written into the preset storage path of the gateway, so that the access of the gateway is realized through the domain name, and the IP address of the gateway does not need to be memorized.
It should be noted that for simplicity of description, the aforementioned method embodiments are all presented as a series of combinations of acts, but those skilled in the art will appreciate that the present invention is not limited by the order of acts described, as some steps may occur in other orders in accordance with the present invention.
