Configuring a Yum Repository

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

If you have access to the Internet, see Configuring a Yum Repository from the Internet.
If the Internet connection is unavailable, see Configuring the Local Yum Repository (openEuler).

Configuring a Yum Repository from the Internet

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

Back up the Yum repository to the bak directory.

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

Open the following file.
1
vi /etc/yum.repos.d/openEuler.repo

Press i to enter the insert mode.

If the OS is openEuler 22.03 LTS SP3, modify the file content as follows:

Configuring the Local Yum Repository (openEuler)

Download the OS image file as required. For details about the download address, see Table 2.
Mount the OS image file. This step uses the Arm-based OS image file as an example. The procedure for mounting the x86-based OS image file is similar.
- Method 1: Upload the OS image file to the /root directory and mount it to the /mnt directory.
  - openEuler 22.03 LTS SP3
    1
    mount /root/openEuler-22.03-LTS-SP3-everything-aarch64-dvd.iso /mnt
  - openEuler 22.03 LTS SP4
    1
    mount /root/openEuler-22.03-LTS-SP4-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.
    Open the fstab file.
    1
    vim /etc/fstab
    
    Press i to enter the insert mode and add the following content to the end of the file.
    openEuler 22.03 LTS SP3
    1
    /root/openEuler-22.03-LTS-SP3-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0
    
    openEuler 22.03 LTS SP4
    1
    /root/openEuler-22.03-LTS-SP4-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0
    
    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 2.a.

Back up the Yum repository.

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

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
    The file path in baseurl is the image mounting path, which is the /mnt directory in 2.
  3. Press Esc, type :wq!, and press Enter to save the file and exit.
  4. Check the local.repo file.
    1
    cat local.repo

Make the Yum repository take effect.

yum clean all
yum makecache
yum list
