Example 1
Referring to fig. 1 and fig. 2, a method for controlling remote power on/off of cluster management equipment, which is used for interaction between the equipment and a server, includes: a shutdown control flow, a startup control flow and a connection flow,

the server sends a shutdown instruction to the equipment;
the client of the equipment carries out shutdown operation according to the shutdown instruction;
the boot control flow includes the steps of:
the server acquires a starting command and generates a starting instruction according to the starting command;

the equipment analyzes the response broadcast packet to obtain a connection IP and a connection port of the server;
and the equipment is connected with the server according to the connection IP and the connection port of the server.
In this embodiment, in the shutdown control flow, in order to effectively manage the device, the device needs to run client software, the client is connected to the server through the TCP, when the server obtains a shutdown command, the server triggers generation of a shutdown instruction, the shutdown instruction is sent to the client of the corresponding device through the network, and after the client of the device receives the shutdown command, the shell command "shutdown-s-t 60" of the system is called, that is, the shutdown action is realized through the operating system.

the server acquires working period information of each device;
the server generates a shutdown command of the corresponding equipment to the specified equipment according to the working period information;
and the server generates a network awakening data packet at preset startup time according to the timing startup command and broadcasts the network awakening data packet through the network.
In this embodiment, in order to perform the on-off processing on the devices in batches, the management terminal may be connected to the server, the on-off time of the devices may be set in batches by the management terminal, the server may continuously poll the on-off time of each device, and when the preset on-off time or the preset off time is reached, the server may send the off command to the designated device at the preset off time according to the timing off command or generate the network wakeup data packet at the preset on time according to the timing on command, and wake up the designated device through network broadcasting.
Example 3
On the basis of embodiment 2, in the shutdown control flow step, the method further includes the steps of: and after receiving a shutdown instruction, counting down according to preset time, and executing shutdown operation after the counting down is finished.
In this embodiment, in order to prevent the device from being stopped in an emergency, after receiving a shutdown instruction, the device invokes a shell command "shutdown-s-t 60" of the system to perform shutdown, where "60" is counted down for 60 seconds, during which time, if the user needs to cancel shutdown, the server sends a shutdown cancellation instruction to the client of the device, and the client immediately invokes the shell instruction "shutdown-a" to cancel shutdown, thereby terminating shutdown.
Example 4
In embodiment 3, the step of the connection process further includes determining whether the response broadcast packet is valid.
In this embodiment, the response broadcast packet includes the MAC address of the requesting device, and after receiving the response broadcast packet, the device in the network determines whether the MAC address in the response broadcast packet matches the local device, and if not, discards the response broadcast packet; and if the response broadcast packet is matched with the connection port, analyzing the response broadcast packet to acquire the connection IP and the connection port of the server.

When the device needs to be powered on, the client cannot be operated because the device is in a power-off state, no connection with the outside exists, and a built-in power-on module does not exist in the device. At this time, a Wake-on-LAN (WOL) technique is required.
Specifically, the startup command generating unit generates a startup command according to the startup command, and the startup command generating unit generates the network awakening data packet according to the startup command, wherein the network awakening data packet comprises the MAC address of the target computer, and the network awakening data packet can be uniquely identified by corresponding equipment in the network due to the uniqueness of the MAC address.

Specifically, the WOL network wake-up technology is a Magic Packet wake-up mode.
A Magic Packet is a broadcast frame containing the MAC address of the destination computer, and because of the uniqueness of the MAC address, the Packet can be uniquely identified in the network, and Magic Packet transmission typically uses a connectionless transport protocol (UDP). The Magic Packet is most simply constructed as a 16-ary FF of 6 bytes, followed by 16 repetitions of the 48-bit MAC address of the destination device, for a total of 102 bytes of the Packet.
Because each device needs to run client software and needs to manually configure the IP address and port of the server, in order to save manpower and material resources, the device and the server can be configured in a UDP broadcast manner.
