Deploying a Ceph Cluster

Create a local source.
1. Install the tool.
```
yum -y install createrepo
```
1. Create a /home/kpsec_rpm directory and copy the generated RPM package to the directory.
2. Go to the /home/kpsec_rpm directory and create repodata.
```
cd /home/kpsec_rpm
createrepo ./
```
1. Go to /etc/yum.repos.d and create a my_ceph_local.repo file.
```
cd /etc/yum.repos.d
vi my_ceph_local.repo
```
1. Edit the my_ceph_local.repo file.
```
[myceph]
name=myceph
baseurl=file:///home/kpsec_rpm
enabled=1
gpgcheck=0
```
1. Update the Yum cache.
```
yum clean all
yum makecache
```
Install Ceph.
For details, see Installing Ceph in the Ceph Block Storage Deployment Guide (CentOS 7.6).
- In the Deployment Guide, the Ceph mirror source is the official Ceph mirror, which is a Ceph RPM package that does not contain the KPS EC feature. Therefore, you need to configure the Ceph mirror source by using the local source.
- Before installing Ceph, run the yum list | grep ceph command to confirm that Ceph is installed from the local source. In the command, myceph is the name of the repo where Ceph components are installed.
- When installing Ceph, you may need to install other third-party software. Ensure that the network connection is normal.
