After you run the preceding command, an error may be reported stating "SSL certificate problem: self signed certificate in certificate chain." This error is caused by an SSL authentication failure. You can run the git config --global http.sslVerify false command to disable SSL authentication and run the preceding command again to avoid this issue.

Move the patch file and source package to the /root/rpmbuild/SOURCES directory.

rpmdev-setuptree
cp /home/oath-toolkit/0001-oath-toolkit-2.6.5-lockfile.patch /home/oath-toolkit/oath-toolkit-2.6.5.tar.gz /root/rpmbuild/SOURCES

Compile the RPM package.

cd /home/oath-toolkit
rpmbuild -bb oath-toolkit.spec

Use the compiled RPM package as the local Yum source.

mkdir -p /home/rpm/oath
cp -r /root/rpmbuild/RPMS/*  /home/rpm/oath/
yum install -y createrepo
cd  /home/rpm/oath && createrepo .

Configure the repo file.
1. Open the local.repo file.

Compiling Ceph

Download the Ceph source package listed in Software Requirements, save the source package to the /home directory, and decompress the package.
```
cd /home && tar -zxvf ceph-14.2.8.tar.gz
```
Modify the yum.conf file.

vi /etc/yum.conf
```
2. Press i to enter the insert mode. Add sslverify=false and deltarpm=0 to the end of the file.
3. Press Esc to exit the insert mode. Type :wq! and press Enter to save the file and exit.

The isa-l version of the Ceph 14.2.8 source code is early. Upgrade it as follows:
1. Go to the src directory.
```
cd /home/ceph-14.2.8/src
```
2. Back up the original isa-l and download the latest isa-l.
```
mv isa-l isa-l.bak
git clone https://github.com/intel/isa-l.git   
```
3. After the upgrade is complete, the aarch64 directory exists in /home/ceph-14.2.8/src/isa-l/erasure_code/.
```
ll /home/ceph-14.2.8/src/isa-l/erasure_code/
```
Install liboath dependencies.
```
yum install liboath liboath-devel -y
```
Pack the modified Ceph source code into a new package in the tar.bz2 format.
```
cd /home && tar -zcvf ceph-14.2.8.tar.bz2 ceph-14.2.8
```

Compile the new Ceph package.

rpmdev-setuptree
cp ceph-14.2.8/ceph.spec /root/rpmbuild/SPECS/
cp ceph-14.2.8.tar.bz2 /root/rpmbuild/SOURCES/
cd /root/rpmbuild/SPECS/
rpmbuild -ba ceph.spec
