detailed description

In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

An embodiment of the present invention provides a server migration method, as shown in Figure 1, the method includes:

Step 101. Scan the server to be migrated to obtain N hard disks to be migrated.

Wherein, N is a positive integer.

It should be noted that the server to be migrated may include disk C, disk D, and disk E, and this N is equal to 3.

Step 102: Acquire the files of N hard disks to be migrated, and convert the file format of the obtained files into a preset file format.

Wherein, the preset file format is a file format supported by the target virtual machine.

Specifically, the file format of the N hard disk files to be migrated may be in img format, but the target virtual machine does not support files in this format, but supports files in qcow2 format. Therefore, the default file format is qcow2 format.

Step 103, sending the converted file to the target virtual machine.

It should be noted that, after the N hard disk files to be migrated are sent to the target virtual machine with the file format converted into a preset file format, the virtual machine is booted to check whether the files on the hard disk to be migrated are successfully migrated.

The server migration method provided by the embodiment of the present invention scans the server to be migrated to obtain N hard disks to be migrated; obtains the files of the N hard disks to be migrated, and converts the file format of the obtained file into a preset file format; wherein, The preset file format is a file format supported by the target virtual machine; the converted file format is sent to the target virtual machine. It can be seen from the technical solution provided by the present invention that when the files of the hard disk to be migrated are obtained, the file format of the files of the hard disk to be migrated is converted into a preset file format, so the acquisition of the files of the hard disk to be migrated and the conversion of the file format are realized. Simultaneously, thereby saving time spent in the server migration process and improving migration efficiency.

The embodiment of the present invention provides another server migration method, as shown in Figure 2, the method includes:

Step 201. Scan the server to be migrated to obtain N hard disks to be migrated.

Wherein, N is a positive integer.

Step 202: Acquire the files of N hard disks to be migrated, and convert the file format of the obtained files into a preset file format through the pre-written file format conversion algorithm in the preset file format conversion interface.

Specifically, the file format conversion algorithm may be written in the preset file format conversion interface in the form of a program.

It should be noted that the preset file format conversion interface is an open interface. If the file format supported by the target virtual machine changes, the file format conversion algorithm can be rewritten to be written into the preset file conversion interface.

Step 203, through the network card of the server to be migrated, sequentially send the file of the i-th hard disk to be migrated after the format conversion to the i-th hard disk created in advance by the target virtual machine according to the destination address.

Wherein, the destination address is the address of the storage space allocated by the server where the target virtual machine is located for data storage of the target virtual machine; i=1, 2...N.

Concretely, the sending of the file of the hard disk to be migrated is based on the hard disk. Assuming that the hard disk of the server to be migrated has C disk, D disk and E disk, then using the network card of the server to be migrated, by configuring Internet Protocol (Internet Protocol, IP) Information such as address, gateway, mask, etc., the file format is converted into the first file of the hard disk to be migrated in the preset file format in turn, that is, the file on the C drive is sent as a whole to the first pre-created file of the target virtual machine according to the destination address. One hard disk, that is, the C drive of the virtual machine; the file format of the second hard disk to be migrated is converted to the preset file format, that is, the file of the D drive as a whole is sent to the pre-created second hard disk of the target virtual machine according to the destination address. Among the two hard disks, that is, the D disk of the virtual machine; the file format of the third hard disk to be migrated is converted to the preset file format, that is, the file of the E disk as a whole is sent to the pre-created target virtual machine according to the destination address The third hard disk is the E disk of the virtual machine.

It should be noted that this method shields detailed information such as the specific operating system, components, and operating environment of the server to be migrated, and migrates all files on the entire hard disk as a unit. The effect is the same as the whole machine migration, and the server to be migrated is completely retained. The operating environment and configuration information it relies on greatly reduces the complicated environment configuration that needs to be done during migration, and also provides a great security guarantee for the stable operation of the server after migration.

The server migration method provided by the embodiment of the present invention scans the server to be migrated to obtain N hard disks to be migrated; obtains the files of the N hard disks to be migrated, and converts the file format of the obtained file into a preset file format; wherein, The preset file format is a file format supported by the target virtual machine; the converted file format is sent to the target virtual machine. It can be seen from the technical solution provided by the present invention that when the files of the hard disk to be migrated are obtained, the file format of the files of the hard disk to be migrated is converted into a preset file format, so the acquisition of the files of the hard disk to be migrated and the conversion of the file format are realized. Simultaneously, thereby saving time spent in the server migration process and improving migration efficiency.

The embodiment of the present invention provides another server migration method, as shown in Figure 3, the method includes:

Step 301. Control the server to be migrated to start, and control the server to be migrated to enter a preset file migration interface.

Step 302. Scan the server to be migrated to obtain N hard disks to be migrated.

Wherein, N is a positive integer.

Step 303: Obtain the files of N hard disks to be migrated, and convert the file format of the obtained files into a preset file format through the file format conversion algorithm pre-written in the preset file format conversion interface.

Step 304, generating a first verification code according to the converted file format.

Specifically, the first check code may be generated by using a preset algorithm to encrypt the file format and convert the files of the N hard disks to be migrated into the preset file format, wherein the preset algorithm may be the fifth version of the message digest algorithm (MessageDigest Algorithm 5, MD5).

Step 305 , through the network card of the server to be migrated, sequentially send the file of the i-th hard disk to be migrated after the file format conversion to the i-th hard disk pre-created by the target virtual machine according to the destination address.

Wherein, the destination address is the address of the storage space allocated by the server where the target virtual machine is located for data storage of the target virtual machine; i=1, 2...N.

Step 306, acquiring N hard disk files to be migrated from the target virtual machine.

Step 307, generating a second check code according to the files obtained from the target virtual machine on the N hard disks to be migrated.

It should be noted that the second check code may be generated by encrypting the files of the N hard disks to be migrated from the target virtual machine using a preset algorithm, wherein the preset algorithm used to generate the second check code should be the same as The preset algorithm used to generate the first check code should be consistent. If the preset algorithm used to generate the first check code is MD5, then the preset algorithm used to generate the second check code should also be MD5.

Step 308, comparing whether the second check code is the same as the first check code.

It should be noted that the purpose of comparing whether the second check code is the same as the first check code is to check whether the files on the hard disk to be migrated are missed or wrongly transmitted during the process of sending them to the target virtual machine.

Step 309 , if the second check code is different from the first check code, resend the converted file to the target virtual machine until the second check code is the same as the first check code.

Specifically, if the second check code is the same as the first check code, it means that the files on the hard disk to be migrated have not been missed or mistransferred; The files on the migrated hard disk are missing or mistransmitted, so the N hard disk files to be migrated are resent to the target virtual machine after the file format is converted to the preset file format, until the generated second checksum is the same as the first The checksums are the same.
