All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the current technical environment, server applications often need to run on multiple operating systems. However, since there are differences between different operating systems, in order to ensure that an application program on an operating system before migration can normally run on an operating system after migration, a developer is required to perform a lot of manual work and code modification in the related art, which requires a lot of time and labor cost. When application cross-system migration is performed, developers need to perform a great deal of modification and adjustment on the application program, code loopholes and potential safety hazards possibly exist, and stability and performance of the application program can be affected. Therefore, there is a need for an operating system migration method that can help developers to quickly and accurately detect and migrate their server applications to a new operating system.
Fig. 1 is a flowchart of a migration method of an operating system according to the present invention, where the migration method of an operating system includes:
s11: determining system information of a first server and a second server, wherein the system information comprises the type of an operating system operated by the server, the version of the operating system and an application program installed by the server;
the migration between the operating systems of the two servers needs to consider whether the operating systems are compatible, and whether the operating systems are compatible or not by the version determinator, and in addition, a plurality of application programs are installed in the servers.
Therefore, system information of the first server and the second server is predetermined for subsequent operating system migration.
S12: adjusting the operating system operated by the first server according to the system information so that the operating system operated by the first server is matched with the operating system operated by the second server;
whether the operation of the new server is compatible with the operating system on the old server, i.e. whether the operating system of the second server is fully compatible with the operating system of the first server, it will be appreciated that there are two different operating systems in the prior art that are compatible, e.g. Anolis OS 7 may be seamlessly compatible with CentOS 7, and Zhuang kylin V10 may be conditionally compatible with CentOS 7.
Specifically, the operating system is adjusted by adjusting the application program.
S13: transmitting an application program installed by the first server to the second server;
if the application program installed in the first server does not exist in the second server, the starting of the second server after the operating system is migrated to the second server is affected, so that the application program installed in the first server needs to be sent to the second server, and the second server can operate normally.
S14: judging whether the second server normally operates based on the application program; if yes, go to step S15;
s15: it is determined that migration of the operating system in the first server to the second server was successful.
If the second server can be started normally, each application device in the first server is proved to be successfully sent to the second server, and the second server successfully installs all application programs and can operate normally. The first server successfully migrates to the second server.
The invention discloses a migration method, a migration system, a migration device and a migration server of an operating system, which relate to the field of data migration and comprise the following steps: determining system information of a first server and a second server; adjusting the operating system operated by the first server according to the system information so that the operating system operated by the first server is matched with the operating system operated by the second server; transmitting an application program installed by the first server to the second server; judging whether the second server normally operates based on the application program; if yes, the operating system in the first server is determined to be successfully migrated to the second server. And automatically comparing the system information of the operating systems operated by the first server and the second server, installing the missing part in the second server, and simultaneously adjusting the operating system operated by the first server to be compatible with the operating system operated by the second server, wherein if the second server can normally operate, the operating system migrated to the second server can normally operate, and the operating system is successfully migrated.
Based on the above embodiments:
in some embodiments, the system information further includes physical hardware configuration of the server, kernel information of the operating system, firewall, network connectivity information, and file directory rights information;
after determining the system information of the first server and the second server, the method further comprises:
and installing the physical hardware configuration of the first server for the second server, and installing the kernel information, the firewall, the network communication information and the file directory authority information of the operating system operated by the first server for the operating system operated by the second server.
The types of operating systems, such as centos, homemade kylin, dragon, etc., are versions of the corresponding operating systems, such as centos operating system 7.2 or 7.3, and further such as windows 10 and windows 11 on office computers, which are versions of the operating systems. The version and kernel information, firewall policy, network connectivity information, file directory authority information and server physical hardware configuration information of the current operating system are mainly collected through the remote shell script, and meanwhile, three-party software and library information such as square font library components, encryption components and the like which are installed in the current server are collected according to the rpm-qa command, and are not available in the original operating system. For example, in office computer windows, the software running at present needs to rely on the dog searching input method, so that the software migration is deployed into a new operating system, the dog searching input method needs to be installed in the new operating system, the non-operating system software and library classes which are similar to the dog searching input method and installed in the original operating system can be automatically scanned through the step, and the information is collected into an information report of an original server.
Only if the kernel information, the firewall, the network communication information and the file directory authority information of the operating system are installed on the second server, the operation of the second server can be normally close to that of the first server.
In some embodiments, before adjusting the operating system running in the first server according to the system information, the method further includes:
judging whether the operating system operated by the second server is compatible with the operating system operated by the first server;
if yes, the operating system running on the first server is not required to be adjusted, and the step of sending the application program installed on the first server to the second server is entered;
if not, the step of adjusting the operating system running in the first server according to the system information is entered.
The adaptation between two operating systems is largely divided into two points: firstly, whether the operation of the new server is compatible with the operating system on the original old server or not, and secondly, whether the configuration of the new server is higher than that of the original old server or not, namely whether the operating system of the migrated server is completely compatible with the operating system of the original server or not. The tool has maintained through expert experience a list of operating systems that are seamlessly compatible with CentOS, e.g., anolis OS 7 is seamlessly compatible with centOS 7, and Anolis V10 is conditionally compatible with centOS 7, and whether the target server hardware configuration is higher than the original server configuration or higher than the running requirements of the migration application (jvm running configuration requirements).
If the operating systems of the two servers are not compatible, the application program in the first server needs to be adjusted, and if the first server is matched with the second server, the adjustment of application software is not needed, so that the migration speed of the operating system is increased.
In some embodiments, before sending the application installed by the first server to the second server, further comprising:
judging whether an application program installed in the first server is missing in the second server;
if yes, the step of sending the application program installed by the first server to the second server is entered;
if not, the step of judging whether the second server normally operates based on the application program is entered.
If the second server comprises all the application programs installed in the first server, the repeated installation of the application programs is not needed, and whether the second server can normally operate is judged directly. If there is a miss in the second server, i.e. the application in some or all of the first server is not included, then it is necessary to determine if the second server is operating properly after the miss is installed.
In the case that the operating system of the second server cannot be fully compatible with the operating system of the first server, testing and modification are required for the application program, namely, the application program of the first server is modified to adapt to the operating system of the second server, and if the migrated application program is incompatible with the new operating system, the software is required to be manually intervened and modified to adapt to the new operating system.
In some embodiments, further comprising:
and the control display module displays the system information, the progress of adjusting the operating system operated by the first server, the progress of sending the application program installed by the first server to the second server and the operation result of the second server.
The display module is arranged, and can display the system information of the first server and the system information of the second server, so that the difference of the system information of the first server and the system information of the second server can be displayed more intuitively. If the operating system of the first server needs to be adjusted, the display module displays the adjustment progress. If the application program of the first server needs to be sent to the second server, the display module displays the sending progress of the application program. And displaying the final operation result of the second server.
The migration process of the operating system is displayed through the display module, so that the migration progress can be determined more intuitively.
In some embodiments, sending the first server-installed application to the second server includes:
the first server is controlled to directly send the application program to the second server.
The application program is migrated from the original server to the target server, SCP commands are executed on the original server in a remote shell script mode, and the application program is directly sent from the original server to the target server.
In some embodiments, sending the first server-installed application to the second server includes:
receiving an application program sent by a first server;
the application is sent to a second server.
When software is migrated, some new servers and old servers cannot communicate, namely the network is not available, so that the software to be migrated cannot be directly sent to the new servers from the old servers, and the migrated software can be migrated to the new servers through transfer, so that the goal of one-key migration is achieved, and the war package of the application program can also be directly uploaded to the target servers.
In summary, the first server may be directly controlled to send the application program to the second server, or may be used as an intermediate bridge to receive the application program sent by the first server and send the application program to the second server.
