When a virtual machine of a virtualization platform is used to run a service, a virtual machine is usually created first, a Linux operating system is installed for the virtual machine, then the service to be run is deployed in the virtual machine, finally the virtual machine is converted into a virtual machine template, and when the same service needs to be deployed subsequently, the virtual machine is directly deployed through the virtualization template. When the Linux virtual machine is deployed through the virtual machine template, the effective IP address is directly configured for the new virtual machine after the deployment of the virtual machine is finished. When a plurality of virtual machines are deployed through the template, the available IP functions are configured for the virtual machines when new virtual machines are deployed, and the method is very practical.
Under the condition that the virtual machine is not accessed, the virtual machine is operated on the virtual machine in the virtual machine management platform, for example, the function of safely closing the virtual machine of the virtual machine management platform is that the closing operation is installed below the virtual machine management platform, and the actual shutdown program is in the virtual machine, so that the same effect of closing the virtual machine and accessing the virtual machine operating system for shutdown can be realized.

Detailed Description
In order to clearly explain the technical features of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings. The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. It should be noted that the components illustrated in the figures are not necessarily drawn to scale. Descriptions of well-known components and processing techniques and procedures are omitted so as to not unnecessarily limit the invention.
The following describes a method and a system for configuring a network for multiple Linux system virtual machines in detail, which are provided by the embodiments of the present invention, with reference to the accompanying drawings.
As shown in fig. 1, the present invention discloses a method for configuring a network for multiple Linux system virtual machines, which comprises the following steps:
s1, forming a compatible Linux operating system list according to the Linux operating system type subjected to the IP configuration program compatibility adaptation;
s2, an IP configuration program built in the virtual machine receives configuration IP operation and IP address information issued by the virtualization platform, and obtains the system type and version of the Linux virtual machine;
s3, checking whether the virtual machine operating system type exists in a compatible Linux operating system list, and when the virtual machine operating system type exists, performing IP configuration through an internal network configuration service; and when the IP configuration program does not exist, performing IP configuration through a network configuration service supported by the IP configuration program.
The embodiment of the invention does not relate to a virtualization management platform, issues the operation of configuring the IP to the inside of the virtual machine, only cares about how the program for configuring the IP running in the inside of the virtual machine can be compatible with various Linux operating systems, and reliably configures the IP address into the virtual machine.
The network card IP configuration program is operated in the virtual machine, a compatible Linux operating system list is maintained, the Linux operating system list basically comprises all Linux operating system types, and the IP configuration programs of the Linux systems in the Linux operating system list are subjected to compatibility adaptation, so that the IP configuration can be more reliably carried out on the virtual machine.
If the Linux virtual machine system type is in the compatible Linux operating system list, the corresponding IP configuration program can be directly run for configuration, and when the IP configuration is performed, network configuration services in the Linux system are used for configuration, for example, a Suse12 version operating system maintains network configuration through a wicked network, most Linux systems maintain network configuration by using a NetworkManager, and the network configuration services all have related network configuration commands to perform IP address configuration on the network cards. The IP address can be better configured by using the network maintenance software in the Linux virtual machine system to configure the IP address.
If the system type of the Linux virtual machine is not in the compatible Linux operating system list, checking whether a network configuration service supported by an IP address configuration program is contained in the Linux system, and if the network configuration service exists and can be used by the service configuration program, using the network service to perform IP address configuration. If the supported network configuration service cannot be detected, a Linux system universal IP configuration mode is used, for example, the network card can be configured by IP commands supported by the Linux system, but the configuration mode can ensure normal configuration of the IP, but the IP address cannot be persisted to a configuration file because the network card configuration rule of the Linux system is unclear, and the IP address may be lost after the system is restarted, so that the network card needs to be configured by the universal IP command again when the IP address is lost after the system is restarted.
And the IP configuration program in the Linux virtual machine receives the configuration IP operation and the IP address information sent by the virtualization platform, acquires the system type and the version of the Linux virtual machine, and checks whether the system type and the version of the Linux virtual machine are in a compatible Linux operating system list.
If the Linux virtual machine system type is the supported system type, executing the following steps:
checking network configuration service in the Linux system, and if the network configuration service is available, carrying out IP configuration through a related configuration command of the network service; and if the network configuration service is abnormal, performing IP configuration through a Linux general IP command.

checking whether a network configuration service supported by an IP configuration program exists in the Linux system, and if the supported network configuration service is available, carrying out IP configuration through a related configuration command of the network service; and if the network service does not exist or is abnormal, carrying out IP configuration through a Linux general IP command.
The embodiment of the invention realizes the network configuration of various virtual machine Linux system virtual machines of a virtualization platform by running the program for configuring the IP inside the Linux virtual machine, detecting whether the Linux virtual machine operating system is in the compatible Linux operating system list by using the program, configuring the IP by using the network configuration service inside the virtual machine, and carrying out the IP configuration on the Linux virtual machine network card by adopting a general IP command when the Linux virtual machine system can not be compatible. The method is simple and easy to implement, can effectively improve the IP configuration efficiency of the network card and saves time.
