Description

Technical Field

[0001] The present invention belongs to the technical field of power monitoring installation, and more specifically, relates to a method and system for partitioning a Kylin V10 hard disk and installing a graphics card through a PXE network. Background Art

[0002] PXE-Kylin V10 network installation automation system uses WIN10-64 bit + VMWARE virtual machine-CENTOS7 system as the installation server, which can install Kylin V10 on multiple computers at the same time. In the installation server, you need to partition the hard disk and then install the graphics driver.

[0003] The PCS9000 computer for power dispatching and monitoring is different from the PCS9700 computer for power substation monitoring. The PCS9700 substation monitoring signal volume is not large, so when partitioning the hard disk, only a folder needs to be created on the root directory, and no special hard disk partition is required when installing the operating system. However, due to the large number of signals, the PCS9000 computer for dispatching requires special hard disk partitioning (mainly time series server partition and historical database partition) when installing the operating system. For different projects, the computer configuration is different, which results in the need to manually modify the KSCFG file in advance or modify it manually during the installation process, and the automatic hard disk partition operation cannot be performed. The current routine operation for installing a graphics card is to install the operating system first, and then manually enter the terminal command to install the independent graphics card driver.

[0004] Existing installation technologies are:

[0005] The patent with announcement number CN117806665A discloses a method, device, equipment and medium for accelerating the installation of a graphics card driver in a WINDOWS operating system, which relates to the field of computer technology, including: obtaining a system driver warehouse driver package directory with the same directory structure as the graphics card driver installation package resource directory, and creating a first resource file in the system driver warehouse driver package directory; creating a second resource file in the system directory based on the corresponding relationship information list obtained by parsing the INF file; using file filtering technology to redirect access to the first resource file and access to the second resource file to files in the graphics card driver installation package resource directory; calling a callback function when creating a new process, if the new process is determined to be a graphics card driver installation process, using thread injection technology to allow the graphics card driver installation process to load a target DLL file; executing a hook target key function, the target key function removes the first attribute and adds the second attribute.

[0006] The patent with publication number CN107193595A discloses a method for installing the NVIDIA graphics driver in the LINUX operating system, which detects whether the nouveau driver in the current system is in operation, and the current system is a system above redhat 6; when the nouveau driver is in operation, the nouveau driver is turned off; the NVIDIA restricted driver in the blacklist is deleted; the installation instruction is executed, and the pre-downloaded NVIDIA graphics driver file is run to complete the installation of the NVIDIA graphics driver. This application successfully installs the NVIDIA graphics driver in a system above redhat 6 by turning off the nouveau driver that causes the NVIDIA graphics driver to fail to install, and deleting the NVIDIA restricted driver in the blacklist.

[0007] However, the above methods all require entering the operating system after installing the operating system, manually modifying the KSCFG file for partitioning, and manually using init 3 to enter the root command line state to execute the graphics card installation command. This takes a long time to use and requires manual intervention, which may cause errors, especially in special environments with complex power monitoring installations. Summary of the invention

[0008] In order to solve the deficiencies in the prior art, the present invention provides a method for partitioning the Kylin V10 hard disk and installing a graphics card through a PXE network. No manual operation is required. Automatic partitioning of computer installation is achieved by selecting the corresponding KSCFG file according to the nature of the computer application, and automatic installation of the graphics card is achieved by modifying the login configuration file of the operating system and the self-executing RC.LOCAL file.

[0009] The first aspect of the present invention proposes a method for partitioning a Kylin V10 hard disk and installing a graphics card on a PXE network. When installing the graphics card, the hardware disk must be partitioned according to the nature and category of the computer. The computer category includes a client computer, a timing server computer, a historical server computer with a disk array, a historical timing server computer with a disk array, a historical server computer without a disk array, and a historical timing server computer without a disk array; the method comprises the steps of:

[0010] Step 1, use LINUX command to obtain the hard disk name and hard disk capacity of the power monitoring system computer;

[0011] Step 2, determine whether the computer is a historical server, if so, determine that a historical database partition needs to be established, and calculate the database partition capacity according to the type of computer database of the power monitoring system where the graphics card is to be installed, otherwise, no database partition needs to be established;

[0012] Use LINUX commands to obtain the computer memory capacity of the power monitoring system and calculate the SWAP partition capacity;

[0013] Calculate the capacity of / boot / efi partition, biosboot partition, / boot partition, timing partition, history partition, root directory / partition according to the computer's boot mode, whether the hard disk is larger than 2T, and whether the computer is a timing or history server;

[0014] Step 3: Perform actual automatic partitioning operations based on the calculated capacity of each partition;

[0015] Step 4: Replace the Kylin V10 operating system boot file by modifying the KSCFG file to eliminate the manual license registration pause during the PXE installation process;

[0016] Step 5: Replace the Kylin V10 operating system startup login configuration file for the first time to implement password-free login for the root user; execute the systemctl command to implement command line login for the root user;

[0017] Step 6: Perform PXE installation. After the system configuration and optimization are completed, use the LINUX command to restart.

[0018] Step 7, use the RC.LOCAL self-executable SH file to automatically install the NVIDIA discrete graphics card;

[0019] Step 8: Replace the Kylin V10 operating system startup login configuration file for the second time, modify it to the file before replacement in step 4, and execute the systemctl command to implement the graphical login of the ems user with a password, and restart using the LINUX command.

[0020] Preferably, in step 1, the process of obtaining the hard disk capacity is: using the LINUX command to obtain the hard disk capacity text descriptor, judging whether there is a "T" or a "G" in the text descriptor and removing the letters in the text descriptor to obtain a number, if there is a "T", the hard disk capacity is the number multiplied by the square of 1024, and if there is a "G", the hard disk capacity is the number multiplied by 1024.

[0021] Preferably, in step 2, the database partition capacity value is calculated according to the type of database: if the database is an NRSQL database, the database partition is / nrsqldata, and / nrsqldata is the folder directory name of the NRSQL database; if the database is a DAMO database, the database partition ratio / dbdata: / dbbak: / dbarch is 16:3:1, and / dbdata: / dbbak: / dbarch are all folder directory names of the DAMO database; if the database is a Jincang database, the database partition ratio is

[0022] / dbdata: / dbbackup is 2:1, where / dbdata: / dbbackup is the folder directory name of the Jincang database.

[0023] Preferably, the specific capacity and division of the historical database partition are as follows: the database partition / nrsqldata capacity of the NRSQL database is at least 1T, and when partitioning, it is determined whether there is a disk array. If so, it is partitioned from the disk array, otherwise it is partitioned from the computer itself;

[0024] DAMO database, determine whether there is a disk array. If so, the database partition calculation formula is:

[0025]

[0026] Among them, C dbdata , C dbbak , C dbarch , C cpzl They are the capacity of database partitions / dbdata, / dbbak, / dbarch, and disk arrays;

[0027] If there is no disk array, the database partition calculation formula is:

[0028]

[0029] Among them, C jsjyp is the total capacity of the computer's hard disk, C reg is the minimum capacity required for other partitions to be allocated, including / boot / efi partition, biosboot partition, / boot partition, timing partition, root directory / partition capacity, C reg Set to at least 1600G;

[0030] Jincang historical database, determine whether there is a disk array. If so, the database partition calculation formula is:

[0031]

[0032] Among them C cpzl , C dbdata , C dabackup They are disk array hard disk capacity and Jincang database partition.

[0033] The capacity of / dbdata and / dbbackup;

[0034] If there is no disk array, the calculation formula for the Jincang historical database partition is:

[0035]

[0036] Among them, C jsjyp is the total capacity of the computer's hard disk, C reg The minimum capacity required for other partitions that need to be allocated, including / boot / efi partition, biosboot partition, / boot partition, timing partition, root directory / partition capacity), C reg Set it to at least 1600G.

[0037] Preferably, in step 2, the calculation of the SWAP partition capacity is specifically as follows: if the memory is less than 64G, SWAP is set to twice the memory capacity; if the memory is greater than or equal to 64G, it is set to the memory capacity; if the memory is greater than or equal to 128G, 128G is taken.

[0038] Preferably, in step 2, the other partitions include a / boot / efi partition, a biosboot partition, a / boot partition, a timing partition, a history partition, and a root directory / partition;

[0039] The computer's startup method, whether the hard disk is larger than 2T, and whether the computer is a timing or historical server are obtained through the KSCFG file.

[0040] Preferably, in step 2, the calculation of the capacity of other partitions is specifically as follows:

[0041] Add a / boot partition with a capacity of 2G; determine the computer boot mode. If the computer is UEFI booted, add a / boot / efi partition with a capacity of 2G. If it is LEGACY booted, determine whether the hard disk capacity is greater than 2T. If so, add a biosboot partition with a capacity of 2G. Otherwise, do not add a biosboot partition.

[0042] Determine whether the computer is a time series or history server. If it is a time series server, add a time series partition / users / ems / rtdata with a capacity of 500G. If the actual measurement point has specific requirements, set it to the required capacity. If it is a history server, determine the database again. If it is an NRSQL database, add a history partition / nrsqldata with a capacity of 500G. If it is a Jincang database, add a history partition

[0043] / home / kingbase, with a capacity of 500G; if it is a DAMO database, add a historical partition / home / dmdba with a capacity of 500G; if it is a time series + historical server, then the corresponding partitions added to the historical server and the time series server are added; the remaining space is the root directory / partition, and the root directory / partition capacity is determined. If it is less than 500G, an error is reported and return to step 1 to repartition.

[0044] Preferably, in step 3, the actual automatic partitioning operation includes:

[0045] All partition capacities are pre-calculated using LINUX commands. Use LINUX commands to modify the KSCFG file. First, clear all partitions. Then create partitions of corresponding capacity based on the required partitions and calculated partition capacities. Finally, use mfx.ext4 to format the hard disk partitions.

[0046] Preferably, in step 4, the modification of the KSCFG file specifically includes: modifying the original firstboot--enable in the KSCFG file to firstboot--disabled, and adding eula--agreed.

[0047] Preferably, in step 5, the first replacement of the Kylin V10 operating system startup login configuration file is specifically to modify the disabled guest mode in the conf class configuration file to the root user mode, and define the command executed when starting the service in the service class configuration file as root.

[0048] Preferably, in step 7, first use the RC.LOCAL self-executable sh file to uninstall the third-party graphics card driver nouveau. After the uninstallation is completed, it will automatically restart. Then use the RC.LOCAL self-executable sh file of the Kylin V10 operating system to install the NVIDIA driver. After the installation is complete, modify the sh file name so that the file will not continue to be executed.

[0049] The second aspect of the present invention proposes a system for partitioning a Kylin V10 hard disk and installing a graphics card using a PXE network of the method described in the first aspect of the present invention, including: a computer property acquisition module, a partition capacity calculation module, a partition module, a registration license pause elimination module, a login configuration file modification module, and an automatic installation module; specifically:

[0050] Computer property acquisition module: obtain the hard disk capacity and memory capacity through LINUX commands, and select the KSCFG file according to the computer's startup mode, whether the hard disk is larger than 2T, and whether the computer is a timing or history server;

[0051] Partition capacity calculation module: calculates the capacity of SWAP partition, historical database partition, / boot / efi partition, biosboot partition, / boot partition, timing partition, root directory / partition according to hard disk capacity, memory capacity and other computer properties;

[0052] Partition module: KSCFG file uses LINUX commands to clear all partitions, then create partitions of corresponding capacity according to the required partitions and calculated partition capacity, and format the hard disk partitions;

[0053] Registration license pause elimination module: modify KSCFG file and replace Kylin V10 operating system startup file;

[0054] Login profile modification module: replace the Kylin V10 operating system startup login profile and execute the systemctl command to implement password-free login for the root user or password-required graphical login for the ems user;

[0055] Automatic installation module: Use the RC.LOCAL self-executable SH file to automatically install the NVIDIA discrete graphics card.

[0056] The beneficial effect of the present invention is that, compared with the prior art, different KSCFG files are configured by computer application properties, and the capacity of each partition is automatically calculated in the early stage of the installation process, which not only considers the hard disk size and memory size, but also considers different databases, different startup modes and special partitions required by history and timing servers, so as to better adapt to power dispatching monitoring PCS9000 computers and other power monitoring system computers with a large number of signals; by calculating the partition value in advance in KSCFG, writing the partition operation, and realizing automatic partitioning, no manual modification is required, saving operation time, and better adapting to power dispatching monitoring PCS9000 computers and other power monitoring system computers with a large number of signals when installing the operating system, reducing the problems and defects caused by the manual partition pause time. The manual registration license pause during the PXE installation process is eliminated by modifying the KSCFG file; and the root user command line password-free login is realized by replacing the Kirin V10 operating system startup login configuration file and executing the command; the self-executable file RC.LOCAL is used to install the independent graphics card NVIDIA, and automatic installation is realized without human intervention, which improves the installation efficiency and installation accuracy. It is more suitable for the PXE automated computer installation workshop assembly line. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] Preferably, in step 2, the database partition capacity value is calculated according to the type of database: if the database is an NRSQL database, the database partition is / nrsqldata, and / nrsqldata is the folder directory name of the NRSQL database; if the database is a DAMO database, the database partition ratio / dbdata: / dbbak: / dbarch is 16:3:1, and / dbdata: / dbbak: / dbarch are all folder directory names of the DAMO database; if the database is a Jincang database, the database partition ratio is

[0070] / dbdata: / dbbackup is 2:1, where / dbdata: / dbbackup is the folder directory name of the Jincang database.

[0071] Preferably, the specific capacity and division of the historical database partition are as follows: the database partition / nrsqldata capacity of the NRSQL database is at least 1T, and when partitioning, it is determined whether there is a disk array. If so, it is partitioned from the disk array, otherwise it is partitioned from the computer itself;

[0089] Add a / boot partition with a capacity of 2G; determine the computer boot mode. If the computer is UEFI booted, add a / boot / efi partition with a capacity of 2G. If it is LEGACY booted, determine whether the hard disk capacity is greater than 2T. If so, add a biosboot partition with a capacity of 2G. Otherwise, do not add a biosboot partition.

[0090] Determine whether the computer is a time series or history server. If it is a time series server, add a time series partition / users / ems / rtdata with a capacity of 500G.
