Configuring the Yum Repository

Configure the Yum repository properly to install the required software and dependencies. Select the appropriate Yum repository configuration method based on your network condition and OS type.

Configuring an Internet Yum Repository

  1. Run the curl command to access any website. If the website information is displayed, the proxy is successfully configured and the Internet is connected.
  2. Check for the Yum repository (a .repo file). If it is available, go to 6.
    1
    ls /etc/yum.repos.d/
  3. Back up the Yum repository to the bak directory.
    1
2
3
    cd /etc/yum.repos.d
mkdir bak
mv *.repo bak
  4. Configure the Internet Yum repository.

    CentOS 7.6:

    1
    wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.huaweicloud.com/repository/conf/CentOS-AltArch-7.repo

    If wget is not installed, run the following command to install it:

    1
    yum -y install wget
  5. View the Yum repository.

    CentOS 7.6:

    1
2
    ls /etc/yum.repos.d/
cat /etc/yum.repos.d/CentOS-Base.repo
  6. Make the Yum repository take effect.

Configuring the Internet Yum Repository (openEuler)

  1. Run the curl command to access any website. If the website information is displayed, the proxy is successfully configured and the Internet is connected.
  2. Check for the Yum repository (a .repo file). If it is available, go to 7.
    1
    ls /etc/yum.repos.d/
  3. Back up the Yum repository to the bak directory.
    1

3
    cd /etc/yum.repos.d
mkdir bak
mv *.repo bak
  4. Open the file.
    1
    vi /etc/yum.repos.d/openEuler.repo
  5. Press i to enter the insert mode.
    If the OS is openEuler 20.03, modify the file content as follows:
    [OS]
name=OS
baseurl=http://repo.openeuler.org/openEuler-20.03-LTS-SP1/OS/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-20.03-LTS-SP1/OS/$basearch/RPM-GPG-KEY-openEuler
[EPOL]
name=EPOL
baseurl=http://repo.openeuler.org/openEuler-20.03-LTS-SP1/EPOL/update/$basearch/

  6. Press Esc to exit the insert mode. Type :wq! and press Enter to save the file and exit.
  7. Make the Yum repository take effect.

Configuring the Local Yum Repository (CentOS & openEuler)

  1. Download the OS image file.
  2. Mount the OS image file.
    • Method 1: Upload the OS image file to the /root directory and mount it to the /mnt directory.
      • CentOS 7.6:
        1
        mount /root/CentOS-7-aarch64-Everything-1810.iso /mnt
      • 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
      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 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
      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.
      1. Check the device symbol corresponding to the OS image.
        1
        ls /dev/sr*
      2. Mount the OS image file to the /mnt directory.
        1
2
3
        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 1.

  3. Back up the Yum repository.
    1
2
3
    cd /etc/yum.repos.d
mkdir bak
mv *.repo bak
  4. Configure the local Yum repository.
    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 file:
        1
2
3
4
5
        [local]
name=local.repo
baseurl=file:///mnt
enabled=1
gpgcheck=0

        In baseurl, the file path indicates the path for mounting the image, which is the directory /mnt in step 2.

      3. Press Esc, type :wq!, and press Enter to save the file and exit.
      4. View the local.repo file.
        1
        cat local.repo
  5. Make the Yum repository take effect.
