Detailed Description
The main implementation principle, the specific implementation mode and the corresponding beneficial effects of the technical scheme of the embodiment of the present application are explained in detail with reference to the accompanying drawings.
Examples
Referring to fig. 1, an embodiment of the present application provides a floating authorization method for a solver, which is applied to a server, and the method includes:
s101, creating and activating a virtual environment;
s102, installing an interface of a solver into the virtual environment, and copying a dynamic link library file of the solver into the virtual environment, wherein an authorization server is provided with authorization permissions of the solver and the solver;
s103, after the dynamic link library file is copied to the virtual environment, compressing the file in which the virtual environment is located to obtain a compressed file;
s104, setting the compressed file and the configuration file of the floating authorization in a distributed file system, so that the distributed file system sends the configuration file and the path of the virtual environment to each node in the distributed file system.
In step S101, a virtual environment may be created and activated in any one machine, for example, a virtual environment may be created and activated on any one node in the distributed file system, a virtual environment may also be created and activated on one machine connected to the authorization server, and a virtual environment may also be created and activated in the authorization server.
In a specific implementation process, the authorization server may be a linux server or a unix server, and a solver is installed in the authorization server, and the solver may be a COPT solver, which is an efficient mathematical programming solver suite for large-scale optimization problems, and can provide solutions for various mathematical programming such as linear programming problems, integer programming problems, and nonlinear problems for clients. However, the solver usually requires authorization, which usually includes a stand-alone authorization and a floating authorization, wherein the stand-alone authorization is installation and authorization on a single machine, the floating authorization is that one machine is used as an authorization server, and the rest N machines (according to the number of purchased tokens) queue to obtain authorization through network requests, wherein N is an integer not less than 2.
Specifically, if the authorization server is a linux server, a python virtual environment can be created in the authorization server and activated, and the floating authorization file of the solver is installed in the directory where the executable file of the authorization server is located. When the floating authorization file is installed in the directory where the executable file of the authorization server is located, the copt _ flserver may be input at the terminal of the authorization server, and the authorization server is further started.
In the practical application process, taking an authorization server as a linux server as an example, a linux server needs to be prepared for use as the authorization server, and a COPT solver is installed on the linux server and obtains a license with floating authorization. Assuming that the following configuration pieces are made on the machine, i.e. Port is a Port opened by floating grant, all nodes in the distributed file system that need to use a COPT solver need to communicate with the machine and the Port, license is a path for reading a certificate, and the code is specifically as follows:
[Main]
Port＝7979
[Licensing]
LicenseFile＝license.dat
PubkeyFile＝license.key。
in turn, the authorization server is configured such that each node in the distributed file system communicates with the authorization server through a port of 7979. Among them, the distributed file system generally employs a Spark framework.
In the embodiment of the present specification, Spark is a mainstream large data processing framework, and large-scale data is processed in a cluster form through a master + slave management mode.
And, after the floating authorization license of the solver is installed in the authorization server and the above configuration is completed, a python virtual environment named copt _ env can be created by using the conda to execute the conda create-n copt _ env, and then the conda activate copt _ env is executed to activate the virtual environment. Of course, other ways of creating a python virtual environment and then activating the created python virtual environment may be used.
After the virtual environment is activated, step S102 is performed.
In step S102, the installation package of the solver may be first obtained, then the installation package of the solver is decompressed, a decompressed solver file is obtained, then the python interface of the solver is obtained from the decompressed solver file, and the python interface is installed in the virtual environment. Of course, the python interface can also be directly obtained from the installation file of the solver and installed in the virtual environment.
In this embodiment of the present specification, since the authorization server needs to perform floating authorization on a node in the distributed file system, the authorization server needs to install a solver and a floating authorization of the solver.
Specifically, if the installation package of the solver is a COPT installation package, the COPT installation package may be decompressed, the lib/python/setup.py is found in the decompressed folder, the python setup.py install may be executed, and the python interface of the COPT may be installed in the python virtual environment.
Specifically, after the decompressed solver file is obtained, all dynamic link library files required by the operation of the solver are obtained from the decompressed solver file, and all the obtained dynamic link library files are used as dynamic link library files of the solver, and then the dynamic link library files of the solver are copied to the dynamic library files of the virtual environment. Of course, all the dynamic link library files required by the operation of the solver can also be directly obtained from the installation files of the solver, and then all the obtained dynamic link library files are copied into the virtual environment.
For example, taking COPT as an example, in a COPT installation package, four dynamic link library files, namely libcopt.so, libcopt _ cpp.so, libcoptcswrap.so and libcoptjniwrrap.so, are located under a lib folder, and are copied into a lib file of a virtual environment, the bottom layer of the COPT is implemented by C + +, and the 4 dynamic link libraries need to be found during operation to be operated, so that the four dynamic link library files are added into the lib file of the virtual environment, and the COPT can be operated in the virtual environment; and installing the python interface of the solver into the virtual environment, so that the nodes in the distributed file system are accessed to the virtual environment through the python interface.
After copying the dynamic link library file to the virtual environment, step S103 is performed.
In step S103, after the interface of the solver is installed in the virtual environment and the dynamic link library file of the solver is copied to the virtual environment, the file in which the virtual environment is located is compressed to obtain a compressed file.
For example, taking COPT as an example, installing a python interface of COPT into a python virtual environment, and copying four dynamic link library files, namely libcopt.so, libcopt _ cpp.so, libcoptcswap.so and libcoptjniwrap.so, below a lib folder in the COPT into a lib file of the python virtual environment; at the moment, the file where the python virtual environment is located is compressed into a ZIP compression package, the transmission data can be reduced by compressing the python virtual environment, and the transmission efficiency is improved.
After the compressed file is obtained, step S104 is performed.
In step S104, the compressed file may be placed into the distributed file system, and the obtained configuration file of the floating authorization may be written into the distributed file system.
Specifically, after obtaining the compressed file, a configuration file of the floating authorization may be obtained, where the configuration file includes an IP address of the authorization server and an externally open interface of the authorization server, and of course, the configuration file may further include obtaining a longest waiting time of the authorization, and the specific codes are as follows:
Host＝192.168.1.11
Port＝7979
QueueTime＝600。
the Host is an IP address of the authorization server, the Port is an externally open Port of the authorization server, and the queue time is the waiting time for obtaining the authorization.
In this embodiment of the present specification, a virtual environment is installed in the authorization server, a solver is run in the virtual environment, and the authorization server is installed with a floating authorization permission, so that when each node in the distributed file system acquires a floating authorization of the solver, it needs to communicate with the virtual environment of the authorization server through the virtual environment of each node to acquire the floating authorization of the solver of the authorization server.
Specifically, the compressed file may be first put into the distributed file system, and the compressed file is decompressed in the distributed file system, so that the distributed file system obtains the virtual environment; and after obtaining the configuration file of the floating authority, the distributed file system is capable of sending the virtual environment and the configuration file to each node in the distributed file system, thereby enabling each node to communicate with the virtual environment in the authorization server through the virtual environment and the configuration file, since the solver is run in the virtual environment in the authorization server, and the authorization server has a floating authorization permission, so that each node can be authorized in turn by the floating authorization permission of the authorization server, while it is communicating with the virtual environment in the authorization server, so that each node can use the solver, and a solver does not need to be installed on each node and the operation and maintenance are carried out on each solver, and only an authorization server needs to be operated and maintained, so that the nodes needing to be operated and maintained are effectively reduced, the operation and maintenance efficiency is effectively improved, and the operation and maintenance pressure is reduced.
Specifically, taking the example that the Spark framework is adopted by the distributed file system, the distributed file system sends the virtual environment and the configuration file to each node in the distributed file system through a pre-distribution mechanism of the Spark framework during running, and a parameter for pointing to the virtual environment needs to be set in the Spark submit script, so that the accuracy of communication between each node and the virtual environment of the authorization server is higher.
For example, when sending the virtual environment and the configuration file to each node in the distributed file system through the pre-distribution mechanism of the Spark framework, the following parameters need to be specified in the Spark submit script, and the COPT can be used on the whole cluster by normally submitting the task.
--files hdfs:///client.ini
--confspark.yarn.dist.archives＝hdfs:///copt_env.zip#pyenv
--confspark.yarn.appMasterEnv.PYSPARK_PYTHON＝pyenv/bin/python
--confspark.yarn.appMasterEnv.PYSPARK_DRIVER_PYTHON＝pyenv/bin/python。
The files parameter specifies to distribute client.ini to each running node, spark.yarn.dist.archives specifies the hdfs path of the PYTHON virtual environment package, yarn can be automatically distributed during running, alias after # is equivalent to alias, spark.yarn.appmasterenv is set with two environment variables, and PYSPARK _ PYTHON and PYSPARK _ DRIVER _ PYTHON respectively point the PYTHON interpreters in Spark Master and Work nodes to the packed PYTHON environment.
In this embodiment of the present specification, as shown in fig. 2, first, a COPT floating authorization server 20 is set, and a COPT dynamic link library 21 and a COPT Python api22 (a Python interface of a COPT) are obtained, the COPT dynamic link library 21 and the COPT Python api22 are installed in a Python virtual environment 23, then the Python virtual environment 23 is compressed, a ZIP-format compressed file 24 is obtained, and then the compressed file 24 is uploaded to an HDFS25 (distributed file system); the HDFS25 employs a Spark framework, and when running, the pre-distribution mechanism of the Spark framework automatically distributes the Python virtual environment 23, so that the Python virtual environment 23 runs in each Spark node 26, and each Spark node 26 can communicate with the Python virtual environment running in the COPT floating authorization server 20 through the Python virtual environment 23 running on its own, so as to queue for authorization, and after each Spark node 26 obtains the COPT authorization, each Spark node 26 can use the COPT for computation.
In the embodiment of the specification, the solver does not support the cluster mode operation, and the solver can be applied to the cluster mode by applying the floating authorization of the solver, so that the solver is applied to a large-scale data solving scene. The technical scheme adopted by the invention is as follows: and installing a Python interface of the solver into a Python virtual environment, and copying the dynamic link library file required by the COPT operation into a dynamic link library folder lib of the Python virtual environment.
Thus, when the Spark program runs, yann will distribute the python environment and the floating authorization configuration file from HDFS (distributed file system) to the master and all worker nodes in advance, replace the python interpreters of all nodes with the previously packaged python environment in the parameter, and since the python virtual environment installs the python interface of COPT during packaging and adds the dynamic link library of the COPT to the dynamic link library of the python virtual environment, all nodes obtaining the python environment package can also find the python interface of the COPT and the dynamic link library of the COPT bottom layer. When the worker node needs to use the copt, the worker node can normally operate only by requesting to obtain the authorization through the started copt floating authorization server. And Spark cluster in the production environment, probably has thousands of nodes, if every node all goes to install the COPT, that can produce huge fortune dimension cost, simultaneously because the authorization of COPT needs the charge, also can produce very big economic cost for all node installation COPT, and this application need not to install the COPT on every node, only need dispose on a server and purchase the authorization of floating and can let the node of operation on the whole cluster all can use the COPT, thereby can effectively reduce cost.
Based on the technical scheme, the virtual environment is created and activated; installing an interface of the solver into the virtual environment, and copying a dynamic link library file of the solver into the virtual environment; after the dynamic link library file is copied to the virtual environment, compressing the file in which the virtual environment is located to obtain a compressed file; the compressed file and the configuration file of the floating authorization are arranged in a distributed file system, so that the distributed file system sends the configuration file and the path of the virtual environment to each node in the distributed file system, in this way, the interface and the dynamic link library of the solver are arranged in the virtual environment, the compressed file and the configuration file of the virtual environment are arranged in the distributed file system, and the path of the configuration file and the path of the virtual environment are sent to each node, so that each node can access the virtual environment, and therefore each node can access the virtual environment in the authorization server to obtain the authorization, and in this way, each node in the distributed file system can effectively finish obtaining the authorization of the solver by accessing the virtual environment without installing the solver on each node and operating and maintaining each solver, only the operation and maintenance of the authorization server are needed, and the nodes needing the operation and maintenance are effectively reduced, so that the operation and maintenance efficiency can be effectively improved, and the operation and maintenance pressure is reduced.
