Configuring a Yum Source

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

If you have access to the Internet, see Configuring a Yum Source from the Internet. openEuler does not allow configuring a Yum source from the Internet. See Configuring a Local Yum Source.
If the Internet connection is unavailable, see Configuring a Local Yum Source.

Configuring a Yum Source 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 for the Yum source (*.repo file). If it is available, go to 5.
1
ls /etc/yum.repos.d/

Back up the Yum source.

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

Configure the Yum source.

Open the file.
1
vi openEuler.repo

Press i to enter the insert mode and modify the file as follows:

If openEuler 20.03 LTS SP1 for AArch64 is used, replace openEuler-22.03-LTS-SP4 with openEuler-20.03-LTS-SP1 in the preceding commands.

Configuring a Local Yum Source

Download the OS image file.
For the download address, see Table 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
  - openEuler 20.03:
    1
    mount /root/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso /mnt
  - openEuler 22.03:
    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
  vi /etc/fstab
  
  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
  
  openEuler 20.03:
  1
  /root/openEuler-20.03-LTS-SP1-everything-aarch64-dvd.iso /mnt iso9660 loop 0 0
  
  openEuler 22.03:
  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.
```
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 an example device symbol. Replace it with that queried in 2.a.

Back up the Yum source.

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

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
    [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. View the local.repo file.
    1
    cat local.repo

Make the Yum source take effect.

yum clean all
yum makecache
yum list
