Configuring the Local Yum Source

Configure the Yum source properly to install the required software and dependencies.

1. Download the OS image file.
   OS image addresses:

   • CentOS 7.6 image: https://mirrors.huaweicloud.com/centos-vault/altarch/7.6.1810/isos/aarch64/CentOS-7-aarch64-Everything-1810.iso
   • CentOS 8.1 image: https://mirrors.huaweicloud.com/centos-vault/8.1.1911/isos/aarch64/CentOS-8.1.1911-aarch64-dvd1.iso
   • openEuler 22.03 LTS SP1 image: https://repo.huaweicloud.com/openeuler/openEuler-22.03-LTS-SP1/ISO/aarch64/openEuler-22.03-LTS-SP1-everything-aarch64-dvd.iso
   • openEuler 20.03 LTS SP1 image: https://repo.huaweicloud.com/openeuler/openEuler-20.03-LTS-SP1/ISO/aarch64/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso
2. Mount the OS image file.
   • Method 1: Upload the OS image file to the /root directory and mount it to the /mnt directory.
     • On CentOS 7.6:

       1	mount /root/CentOS-7-aarch64-Everything-1810.iso /mnt

     • On CentOS 8.1:

       1	mount /root/CentOS-8.1.1911-aarch64-dvd1.iso /mnt

     • openEuler 20.03:

       1	mount /root/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso /mnt

     • openEuler 22.03:

       mount /root/openEuler-22.03-LTS-SP1-everything-aarch64-dvd.iso /mnt

     

     Rename the ISO file based on your requirements. The renaming operation takes effect only once and becomes invalid after a system restart. You can perform the following operations for the image file to be automatically mounted upon system startup.

     1. Open the fstab file.

        1	vim /etc/fstab

     2. Press i to enter the insert mode, and add the following content to the end of the fstab file:
        • CentOS 7.6:

          1	/root/CentOS-7-aarch64-Everything-1810.iso /mnt iso9660 loop 0 0

        • CentOS 8.1:

          1	/root/CentOS-8.1.1911-aarch64-dvd1.iso /mnt iso9660 loop 0 0

        • openEuler 20.03:

          1	/root/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0

        • openEuler 22.03:

          /root/openEuler-22.03-LTS-SP1-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0

     3. Press Esc, type :wq!, and press Enter to save the file and exit.

   • Method 2: Use a browser to log in to the BMC and use the KVM to load the OS image file to the /mnt directory.
     1. Check the device symbol corresponding to the OS image.

        ls /dev/sr*

     2. Mount the OS image file to the /mnt directory.

        mount /dev/sr0 /mnt
        df -h | grep /mnt
        ls /mnt/

        

        /dev/sr0 is the device symbol corresponding to the OS image, which must be the same as that queried in 2.a.

3. Back up the Yum source.

   cd /etc/yum.repos.d mkdir bak mv *.repo bak

4. Configure the local Yum source.
   1. Go to the /etc/yum.repos.d directory.

      1	cd /etc/yum.repos.d

   2. Create a local.repo file.
      1. Open the local.repo file.

         1	vim local.repo

      2. Press i to enter the insert mode and add the following content to the local.repo file:

         1 2 3 4 5 6 7 8 9 10

         [local-BaseOS] name=local.repo baseurl=file:///mnt/BaseOS/ enabled=1 gpgcheck=0 [local-AppStream] name=local.repo baseurl=file:///mnt/AppStream/ enabled=1 gpgcheck=0

         

         The file path in baseurl is the image mount path, which is the /mnt directory in 2.

      3. Press Esc, type :wq!, and press Enter to save the file and exit.
      4. View the local.repo file.

         cat local.repo

5. Make the Yum source take effect.
