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 a Local Yum Repository.

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. If an Internet Yum repository exists (a .repo file exists and the Yum repository address is specified in the file), go to 7.

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 and configure the file as follows:

Press Esc to exit the insert mode. Type :wq! and press Enter to save the file and exit.

Make the Yum repository take effect.

yum clean all
yum makecache
yum list

Configuring a Local Yum Repository

If an Internet Yum repository has been configured, skip this section.

Download the full repository (the "everything" version) of the openEuler OS.

wget https://repo.openeuler.org/openEuler-22.03-LTS-SP3/ISO/aarch64/openEuler-22.03-LTS-SP3-everything-aarch64-dvd.iso

Mounting the OS Image
- Upload the OS image file to the /root directory and mount it to the /mnt directory.
  1
  mount /root/openEuler-22.03-LTS-SP3-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.
  1
  /root/openEuler-22.03-LTS-SP3-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0
  
  Press Esc, type :wq!, and press Enter to save the file and exit.

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 mount 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
