Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. 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.

Based on the above problems, the present invention provides a remote control management method, which virtualizes a computer into a plurality of logical computers through a virtualization technology. A plurality of logic computers are operated on one computer at the same time, each logic computer can operate different operating systems, and application programs can operate in mutually independent spaces without being influenced, so that the working efficiency of the computer is remarkably improved. The method for redefining and planning the IT resources by using the software can realize the dynamic allocation, flexible scheduling and cross-domain sharing of the IT resources, improve the utilization rate of the IT resources, enable the IT resources to be truly an infrastructure and serve the flexible and variable application requirements in various industries.
The execution flow of the method is shown in fig. 1, and comprises the following steps:
s101, at least one KVM virtual machine is built in a client in advance, wherein each KVM virtual machine is used for controlling a corresponding server;

The imann 200 is a single mouse function that can hide the mouse on the local PC in the KVM interface, leaving only the mouse on the live desktop to provide a more convenient operating experience.
The remote control principle based on the KVM virtual machine in the client is that the graphic interface of the KVM virtual machine on a remote server is transmitted to the local through network connection so as to realize the remote control and management of the virtual machine. It typically uses a remote desktop protocol (such as VNC) or SPICE protocol to transport the graphical interface.
The method comprises the following steps:
1. on the remote server, the graphical interface of the KVM virtual machine is converted into pixel data.
2. Pixel data is transmitted locally across the network.

Otherwise, the target virtual machine corresponding to the control request does not exist, and the result is fed back.
S103, based on the target KVM virtual machine, issuing the control request to the target server so as to enable the target server to respond to the control request;
in the embodiment of the invention, the client accesses the front-end proxy service in an https mode to realize Http data interaction and ssl encryption, after authentication is completed, the Http Post form realizes that the front-end proxy server requests to send a managed node request, wherein the front-end proxy server completes encryption and unloading actions of a certificate on the https service, in addition, the front-end proxy server also bears static page loading and backward forwarding functions of the first request of the client, the application server receives a proxy server control request, acquires a request data field in the control request, semantically analyzes and sequences the request data field into a Json character string, receives the proxy server request and sends data to the managed node in parallel in a non-blocking thread and IO multiplexing mode, and the application server locally uses a php json_node () function to construct the authentication request and the request which can be identified by the managed node iI, and information acquisition and other requests, and considers the problem of unified signing and signing of the BMC certificate, and the X509 is a private certificate by-pass.

In the embodiment of the invention, a KVM remote console can be constructed based on the method, wherein the KVM remote console executes the remote control management method, and the KVM remote controller can realize a visual graphical interface. The system provides a series of management deployment tools such as hardware state monitoring, deployment, energy saving, safety and the like, comprehensively monitors various components of the server, realizes a deep fault diagnosis and fault prediction mechanism of key components of the server, and also provides a series of fault auxiliary positioning tools.
In the embodiment of the invention, the kvm remote console is a software integration environment, and a JER environment (namely Java, extJS and RESTful services) is needed to realize the related functions of the highly fused WEBUI. The JER environment provides support for the Java language so that developers can write the relevant code of the KVM remote console using the Java language. At the same time, the JER environment also integrates an ExtJS framework that can be used to build user interfaces, and is highly customizable and extensible. Furthermore, the JER environment also uses RESTful services to enable communication and data exchange with backend systems.
The method for realizing the high fusion of the KVM remote console tool and the WEBUI related functions is realized through an oVirt management platform. The oVirt is an open source KVM virtualization-based management tool and cloud computing platform that provides complete virtual machine management and monitoring functionality, and provides a Web-based user interface so that a user can manage and control a KVM virtual machine through a Web browser.
The WEBUI of oVirt provides a convenient and easy-to-use graphical interface through which a user can create, edit, start, stop, and delete virtual machines. Meanwhile, the system also provides the functions of monitoring the virtual machine resources and performance statistics, and a user can check the running state of the virtual machine, CPU, memory, network use conditions and other information through WEBUI.
In addition to basic virtual machine management functions, oVirt also supports high-level functions such as virtual machine cloning, snapshot, virtual machine migration, and the like. The user may perform these operations through the WEBUI without using command lines or other tools. In summary, the WEBUI of oVirt provides a convenient and powerful interface that highly fuses the KVM remote console tool with WEBUI-related functions so that a user can easily manage and control the KVM virtual machine through a Web browser
For example, as shown in fig. 2, a specific implementation schematic diagram is that a client sends Https/SSL and httproof (ID, psw, …), after receiving Https/SSL and httproof (ID, psw, …), the Apche server submits a request to execute a corresponding PHP script, the PHP calls a C/PHP interactive function and Json string data to pme_web.c, pme_web.c sends Json (VerifyValue, decrykey, …) to the PHP, the PHP forwards the data to the response generated by the server in an echo manner, and the Apche server delivers httpropense (VerifyValue, decrykey, …) to the client.
