Problems solved by technology

The conversion speed between the main and standby machines also has certain disadvantages, such as high cost and long development cycle
And the main and standby machines use two sets of IPs, which cannot realize multiple switching of the main and standby machines

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] as attached figure 2 Shown, the present invention provides a kind of method based on the dual-system hot backup of the same IP of ARM, and its specific implementation process is:

[0027] In the device with built-in ARM platform, the host and backup use the same IP, and the network card of the backup is disabled; the communication between the host and backup is performed through the serial port. When the backup cannot receive information from the host normally, the It is considered that there is a problem with the main machine, and the network card is enabled on the standby machine at this time.

[0028] There are two technical difficulties in the method of dual-computer hot backup based on the same IP on the ARM platform, which are: serial port communication under ARM, and disabling and enabling network cards under ARM.

Abstract

The invention discloses a method for hot standby of dual servers using same IP based on ARM. In a device with a built-in ARM platform, a main server and a standby server use the same IP, and a network card of the standby server is forbidden; and communication between a main server device and a standby device is carried out through a serial port, when the standby server cannot normally receive main server information, the main server is considered as having problems, and at the moment, the standby server starts the network card. Compared with the prior art, the method for hot standby of dual servers using same IP based on ARM has a simple integral implementation process, effectively reduces development cost, needs short development cycle, facilitates deployment and use of small applications, can conveniently realize switching of the main server and the standby server for many times at a fast speed, needs relatively low switching cost, is highly practical, and is easy to generalize.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a practical ARM-based dual-computer hot backup method with the same IP. Background technique [0002] Traditionally, dual-system hot backup is based on the Windows platform. Use two IPs to monitor whether the master and backup machines are normal through socket communication. [0003] Today, with the rapid development of the mobile terminal, devices and applications based on the ARM platform are more and more popular due to their small size, high efficiency, and low cost. In particular, some small applications have gradually migrated from the Windows platform to the ARM platform. become a trend. [0004] Dual-machine hot backup is a method to ensure 7*24 hours of uninterrupted service as much as possible. After the main machine fails, the standby machine will start quickly to ensure the normal and uninterrupted operation of the service. Common interface connection methods in...
