Preparing the Environment

The server OS is openEuler 20.03 LTS SP1.

1. Configure the mirror source.
   1. Configure the local liboath source.
      1. Create a directory used as the Yum source.

         mkdir -p /home/oath

      2. Copy all files in the /root/rpmbuild/RPMS/ directory of the compilation server to /home/oath/.
      3. Use the copied RPM package as the local Yum source.

         1 2	cd /home/oath createrepo .

         

         If the createrepo command is not found, run the yum install createrepo command.

   2. Configure the Repo file.

      1	vi /etc/yum.repos.d/local.repo

      Add the following content to the file:

      1 2 3 4 5 6

      [local-oath] name=local-oath baseurl=file:///home/oath enabled=1 gpgcheck=0 priority=1

   3. Add an external mirror source.

      1	vi /etc/yum.repos.d/openEuler.repo

      Add the following content:

      1 2 3 4 5 6

      [arch_fedora_online] name=arch_fedora baseurl=https://repo.huaweicloud.com/fedora/releases/34/Everything/aarch64/os/ enabled=1 gpgcheck=0 priority=2

      

      If the connection to the external mirror source fails, delete the mirror source information from [arch_fedora_online] and manually download compat-openssl10-1.0.2o-5.fc30.aarch64.rpm.

      Download address: https://archives.fedoraproject.org/pub/archive/fedora/linux/releases/30/Everything/aarch64/os/Packages/c/

   4. Add a Ceph source and create ceph.repo.

      1	vi /etc/yum.repos.d/ceph.repo

      [Ceph] name=Ceph packages for $basearch baseurl=http://download.ceph.com/rpm-nautilus/el7/$basearch enabled=1 gpgcheck=1 type=rpm-md gpgkey=https://download.ceph.com/keys/release.asc priority=1 [Ceph-noarch] name=Ceph noarch packages baseurl=http://download.ceph.com/rpm-nautilus/el7/noarch enabled=1 gpgcheck=1 type=rpm-md gpgkey=https://download.ceph.com/keys/release.asc priority=1 [ceph-source] name=Ceph source packages baseurl=http://download.ceph.com/rpm-nautilus/el7/SRPMS enabled=1 gpgcheck=1 type=rpm-md gpgkey=https://download.ceph.com/keys/release.asc priority=1
