How Can I Use a EulerOS Image Source (x86_64 or Arm) Provided by HUAWEI CLOUD?

Updated at: May 06, 2020 GMT+08:00

Scenarios

When updating the OS or software of an ECS, you can access the ECS to the Internet and use an external EulerOS image source. However, if your ECS cannot access the Internet, or the external EulerOS image source cannot provide services stably, you can use the EulerOS image source provided by HUAWEI CLOUD.

Constraints

  • The operations described in this section apply to ECSs deployed on x86_64 or Arm (Kunpeng) servers.

Procedure

  1. Log in to the ECS.
  2. Run the following commands to back up the Euler repo file:

    mkdir -p /etc/yum.repos.d/repo_bak/

    mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/repo_bak/

  3. Select a suitable curl command to download the Euler-Base.repo file of the desired version and save the file into /etc/yum.repos.d/.
    • x86_64 (only EulerOS 2.2 is supported)

      curl -o /etc/yum.repos.d/EulerOS-base.repo http://mirrors.myhuaweicloud.com/repo/EulerOS_2_x_base.repo

      For example, if EulerOS 2.2 is used, change x in EulerOS_2_x_base.repo to 2 in the following command:

      curl -o /etc/yum.repos.d/EulerOS-base.repo http://mirrors.myhuaweicloud.com/repo/EulerOS_2_2_base.repo

    • Arm (only EulerOS 2.8 is supported)

      curl -o /etc/yum.repos.d/EulerOS-base.repo http://mirrors.myhuaweicloud.com/repo/EulerOS_2_8_base.repo

  4. Run the following command to generate a cache:

    yum makecache

    After the command is executed, if the system displays the message "Another app is currently holding the yum lock", run the rm -rf /var/run/yum.pid command to delete the yum.pid file. Then, run the yum makecache command again to generate the cache.
