FIG. 1 is a block diagram of an embodiment of a method of remotely executing functions on multiple servers in accordance with the present invention.
Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention and are not to be construed as limiting the present invention.
The invention discloses a method and a device for simultaneously controlling a plurality of servers and sending instructions based on RPC technology.
The invention relates to a device for executing functions on a plurality of servers remotely, which mainly comprises the following two modules: an RPC Server module (RPC Server module) and an RPC Client module (RPC Client module);
the RPC Server module is an RPC Server terminal started on the controlled Server, all the RPC Server modules on the controlled Server need to bind the IP and the port of the Server, the RPC Server exposes the bound IP, port and function, the RPC Server always waits for the parameter transmitted by the RPC client module in a circulating way, and the corresponding function is executed after the parameter instruction of the RPC client module is received.
The RPC Client module is a Client to be executed on a host controlling other servers, the IP and the port of the Server to be controlled are bound, after the RPC Client module binds the IP and the port of the RPC Server to be controlled, the RPC Client module can be used for transmitting parameters to the RPC Server module to control the RPC Server module to execute the exposed function, and the control Server starts corresponding services through different parameters.
The invention discloses a method for executing functions on a plurality of servers remotely, which is realized by the following specific ideas:
all PC hosts in the system are linked through the same local area network, so that communication can be ensured. The controlled host is used as an RPC service end, RPC service is started at the appointed IP and port, the RPC service appoints a specific method which is exposed at the specific port, the method receives a character string parameter, and different commands are executed according to the content of the parameter.
The control host is used as an RPC client, creates an RPC link, uses IP and ports to link to the service of the RPC server host, and the RPC client object can execute the method exposed by the RPC server and control the server host by executing the parameter input by the method.
One host computer remotely controls a plurality of host computers, an RPC server end is required to be deployed on the controlled plurality of host computers, the control host computer deploys an RPC client end, and the client end links the plurality of RPC server ends and executes a corresponding method to send an instruction so as to control the plurality of host computers, so that the remote execution of commands on a plurality of servers can be realized.
As shown in fig. 1, a schematic diagram of an embodiment of the present invention is shown. There are five hosts and testing requires that responsive commands be executed on each of the 5 hosts to initiate a service.
The invention can be used for starting the RPC client service on the pc1, starting the RPC server and the RPC client service on the pc2, the pc3 and the pc4 and starting the RPC server service on the pc5, so that multiple hosts can be controlled in series at the same time, and the online test and other works of multiple servers can be performed.
There are five hosts, host pc1 for the operator to perform the test work. Four services server1, server2, server3, server4 on which the test work depends are deployed on pc2, pc3, pc4, pc5, respectively. pc2, pc3, pc4, pc5 all initiate the RPC service of the present invention. pc1, pc2, pc3, pc4 may all launch RPC clients in the present invention. pc1 indirectly controls the management of all services through control of pc 2.
When the RPC services of pc2 and pc3 are started, pc1 sends instructions to pc2 to let pc2 start server1 and server2.Pc2 will start its own server1 and send an instruction to Pc3 to let Pc3 start server2, and Pc3 starts server2 after receiving the instruction. Control of all services can be accomplished in a similar manner. Thus, all services deployed on other multiple hosts are started through one instruction.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereto, and any modification made on the basis of the technical scheme according to the technical idea of the present invention falls within the protection scope of the present invention.
