Detailed Description
In the prior art, the AIX operating system can only run on the big core Power9 processors such as E980, E950, S924, etc., which limits the application scope of the AIX operating system.
The embodiment of the application discloses a method for operating an AIX system on a small core architecture, referring to FIG. 1, the method may include the following steps:
step S11: the hardware layer is built based on a Power9 server containing a corelet processor.
In this embodiment, a hardware layer is first built by using a Power9 server including a small core processor, and it can be understood that a server of a small core architecture processor, for example, a K1 PowerLinux server, is selected in the hardware layer.
In this embodiment, the building a hardware layer based on the Power9 server including the small core processor may include: configuring the Power9 server containing the small core processor according to a target configuration standard to build the hardware layer; the target configuration standard comprises at least two OpenPower9 CPUs, two 16GB memory banks, a disk with a memory larger than 240GB, a RAID card, a network card and a group of 550W power supplies; the basic information of the server is checked by a 1shw command to check whether the server meets the target configuration standard. It will be appreciated that, to meet the requirement of installing an operating system on a host in a subsequent boot, the Power9 server may be configured to be at or above a target configuration standard, that is, the Power9 server may include at least two OpenPower9 CPUs, two 16GB memory banks, a disk with a memory greater than 240GB, a RAID card, a network card, a set of 550W Power supplies, and some required peripheral accessories. After the configuration of the hardware device is completed, the basic information of the Power9 server may be checked by the command 1shw to check whether the Power9 server meets the target configuration standard, specifically, the command 1shw includes but is not limited to lshw-class processor, lshw-class memory, lshw-class storage, lshw-class disk, and lshw-class network, so that the hardware configuration information may be checked.
Step S12: and installing a baseboard management controller of a target version on the basis of the hardware layer to build a firmware layer, and installing an operating system of the target version on the basis of the firmware layer.
In this embodiment, a target version of baseboard management controller (BMC, baseboard Management Controller) is installed on the basis of the hardware layer to build a firmware layer, where the target version of baseboard management controller may be a high version of BMC supporting an os8.0 and above, such as a 4.22.0 version of BMC; then installing a target version of operating system on the basis of the baseboard management controller, wherein the target version of operating system can be CentrOS8.0 or more.
Step S13: and configuring a starting item based on a preset command field so that the operating system can adjust the default memory management mode of the Power9 server into a hash page table by running the starting item.
In this embodiment, after the installation of the operating system is completed, a startup item is configured based on a preset command field, so that the operating system adjusts a default memory management mode of the Power9 server into a Hash (Hash) page table by running the startup item; it can be understood that the memory management modes of the Power9 server include two modes of a Radix page table and a Hash page table, the Open Power9 chip introduces the Radix page table on the memory page, especially the TLB (Translation Lookaside Buffer, translation look-aside buffer) management, and the conventional Hash page table, so that the AIX system virtualized by the Power vm follows the default memory management mode of the host, and therefore, in order for the AIX operating system to run on the Power9 server of the corelet architecture, the default memory management mode of the host needs to be adjusted to the Hash page table. After the configuration of the startup item is completed, whether the memory management mode of the server is a hash page table or not can be checked through a tail/proc/cpu info path, and whether the preset command field exists or not can be checked through a cat/etc/grub2.Cfg path, so that the completion of the installation and the successful configuration of the operating system can be verified.
Step S14: and installing and starting a virtual machine on the basis of the operating system by utilizing target virtualization software and an optical disk image file of the AIX system so as to realize the operation of the AIX system.
In this embodiment, after the installation of the operating system is completed, the virtual machine is installed and started on the basis of the operating system by using the target virtualization software and the optical disc image file of the AIX system to implement the operation of the AIX system. The target virtualization software may be QEMU (virtual operating system simulator).
In this embodiment, the installing and starting a virtual machine on the basis of the operating system to implement the operation of the AIX system by using the target virtualization software and the optical disc image file of the AIX system may include: acquiring a QEMU source file, and generating a corresponding QEMU binary file under a designated directory through detection, compiling and installation operations; modifying the QEMU binary file based on preset configuration parameters to configure virtual machine starting parameters; the preset configuration parameters comprise parameter fields for closing the target type patches; and installing and starting a virtual machine by utilizing the modified QEMU binary file and the optical disk image file of the AIX system to realize the operation of the AIX system.
It can be understood that in this embodiment, the QEMU source file may be obtained through the gilthub platform, and then the foregoing QEMU source file may be detected, compiled and installed through configure, make and make install commands by using a compiling tool such as gcchmake, which is installed in advance. After successful installation, a binary file of the QEMU, QEMU-system-ppc64, is generated under the specified directory. At this time, in order to ensure the normal start of the AIX system, patches of the loopholes mesdown and specrum need to be closed, so that the QEMU binary file is modified based on a preset configuration parameter to configure virtual machine start parameters, where the preset configuration parameter includes a parameter field for closing the target type patch, specifically, after the field "mainnesubs", a parameter field "cap-ccf-assist= off" for closing the target type patch is added to close the patches of the mesdown and specrum. Then, a virtual machine is installed and started to realize the operation of the AIX system by using the modified QEMU binary file and an optical disc image file of the AIX system, wherein the AIX system can be an AIX7.2 version system. The AIX system is restarted after being installed, the read-only optical disc is removed, the AIX virtual machine is started, and the version of the AIX system can be checked through an oslevel-r command. For example, as shown in fig. 2, through the above system configuration steps, the AIX system may be implemented to run on a server of the small core processor structure, so that not only a Linux system or the like, but also the AIX system may be run on the server of the small core processor structure, and the runnable environment of the AIX system and the system carrying capacity of the server of the small core processor structure are enlarged.
After the QEMU binary file is obtained, loading tun, tap and macvtap modules can be further set through the system to establish a bridging network card, namely, establish connection between a virtual machine network card and a physical machine network card, and set an access range of a network IP address through a Dynamic Host Configuration Protocol (DHCP).
In this embodiment, after the installing and starting the virtual machine to implement the operation of the AIX system, the method may further include: and installing an Oracle database at an application layer, and performing system operation test on the AIX system by using a TPCCRunner. It can be appreciated that the Power server runs the Oracle database, DB2 database in conjunction with the AIX operating system, which is a classical combination of IBM minicomputer, oracle database, and EMC storage. In this embodiment, in order to verify the availability of the AIX system at the application layer part, a system operation test may be performed by TPCCRunner. Through testing, when the Power9 server in the embodiment uses only one side resource when NUMA is not bound, the AIX system can reach 2.3 ten thousand TPS (system throughput).
From the above, in this embodiment, a hardware layer is built based on a Power9 server including a small core processor; installing a baseboard management controller of a target version on the basis of the hardware layer to build a firmware layer, and installing an operating system of the target version on the basis of the firmware layer; configuring a starting item based on a preset command field so that the operating system can adjust a default memory management mode of the Power9 server into a hash page table by running the starting item; and installing and starting a virtual machine on the basis of the operating system by utilizing target virtualization software and an optical disk image file of the AIX system so as to realize the operation of the AIX system. Therefore, the default memory management mode of the Power9 server is adjusted to be the hash page table by configuring the starting item based on the preset command field in the kernel layer, then the virtual machine is installed and started on the basis of the operating system by utilizing the target virtualization software and the optical disk image file of the AIX system so as to realize the operation of the AIX system, the limit of kernel parameters is broken through, and the AIX operating system can be operated on the Power9 server of the small-kernel architecture.
