Referring specifically to fig. 2, fig. 2 is a flowchart of a method for creating a blockchain according to an embodiment of the present invention, where the method for creating a blockchain may be performed by a blockchain creating device, where the creating blockchain device is disposed in a node of a blockchain network in a port detection system, and the specific explanation of the port detection system is as described above. Specifically, the method of the embodiment of the invention comprises the following steps.

S201: and receiving a port detection instruction which is sent by the blockchain management platform when receiving a creation instruction of a target blockchain, wherein the port detection instruction carries port segment information.

In the embodiment of the invention, the node can receive a port detection instruction sent by the blockchain management platform when receiving a target blockchain creation instruction, the port detection instruction carries port segment information, and in some embodiments, the port detection instruction is sent by the blockchain management platform to each node related to the target blockchain, and the target node is any one of the nodes. In certain embodiments, the port segment information includes, but is not limited to, information of one or more port segments; for example, the port segment information carried by the port detection command is 16000-17000; in some embodiments, a plurality of ports are included in one port segment. In certain embodiments, the blockchain management platform includes, but is not limited to, a mass platform.

S202: and detecting the state of each port in the plurality of ports corresponding to the port segment information according to the port segment information.

In the embodiment of the invention, the node can detect the state of each port in the plurality of ports corresponding to the port segment information according to the port segment information. In certain embodiments, the plurality of ports includes, but is not limited to, greater than or equal to 4 ports.

In one embodiment, when detecting the state of each of the plurality of ports corresponding to the port segment information according to the port segment information, a node may send a detection command to each of the plurality of ports corresponding to the port segment information through a proxy process of the blockchain management platform, so that each port responds to the detection command to detect the respective state, and acquire the respective state returned by each port. In no embodiment, the probe command includes, but is not limited to, an lsof command. In some embodiments, the order in which the proxy process of the blockchain management platform sends the probe command to each of the plurality of ports corresponding to the port segment information is not specifically limited.

In one embodiment, when detecting that the state of a first port of the plurality of ports is an occupied state, the node may send the probe command to a next port of the first port through the proxy process when sending the probe command to each port of the plurality of ports corresponding to the port segment information through the proxy process of the blockchain management platform, so that the next port responds to the probe command to probe its own state. In some embodiments, the proxy process includes, but is not limited to, an a process.

In one example, assuming that the first port is a port with port number 16000, when detecting that the state of port 16000 is an occupied state, a node may send an lsof command to the next port 16001 of the port 16000 through a proxy process to cause the next port 16001 to probe 16001 for its own state in response to the lsof instruction.

In one embodiment, when detecting that the state of the first port is an idle state, the node may record the port number of the first port into a target port set, acquire the number of port numbers recorded in the target port set, and determine whether to send the probe command to the next port of the first port according to the number of port numbers recorded in the target port set. By the implementation mode, the ports in the target port set can be ensured to be available ports in an idle state, the effectiveness of the ports in the target port set is improved, and the effectiveness of a blockchain created by using the ports in the target port set is improved.

In one example, assuming that the first port is a port with port number 16000, when detecting that the state of port 16000 is an idle state, the node may record the port number 16000 of the port 16000 into a target port set, and obtain the number of port numbers recorded in the target port set.

In one embodiment, when determining whether to send the probe command to the next port of the first port according to the number of port numbers recorded in the target port set, the node may detect whether the number of port numbers recorded in the target port set is smaller than a specified number, and when the detection result is yes, send an lsof command to the next port of the first port, so that the next port of the first port responds to the probe command to probe the state of the next port of the first port, and when the detection result is no, stop sending the probe command to the next port of the first port. In certain embodiments, the specified number is 4.

In one example, assuming that a first port is a port with port number 16000, when detecting that the state of port 16000 is an idle state, a node records port number 16000 of port 16000 into a target port set and obtains the number of port numbers recorded in the target port set, and if detecting that the number of port numbers recorded in the target port set is 3 or less than a specified number 4, the lsof command may be sent to the next port 16001 of port 16000 to cause the next port 16001 of port 16000 to probe the state of the next port 16001 of port 16000 in response to the lsof command.

In one example, assuming that the first port is a port with port number 16000, when detecting that the state of port 16000 is idle, a node records port number 16000 of port 16000 into a destination port set and obtains the number of port numbers recorded in the destination port set, and if detecting that the number of port numbers recorded in the destination port set is 4 equal to the specified number 4, the node may stop sending lsof commands to the next port 16001 of port 16000.

Therefore, by the embodiment, the detection command is stopped from being sent to other ports when the ports in the idle state with the specified number are acquired, and the situation that the other ports are detected after the ports in the idle state with the specified number are detected, so that resource waste is caused is avoided.
