Ceph is primarily distributed from download.ceph.com which is based in the US.
However, globally there are multiple mirrors which offer the same content. Often faster than downloading from the primary source.
Using the script found in this directory you can easily mirror Ceph to your local datacenter and serve packages from there to your servers.
If you want to mirror Ceph please follow these guidelines:
- Please use a mirror close to you
- Do not sync in a shorter interval than 3 hours
- Avoid syncing at minute 0 of the hour, use something between 0 and 59.
The 'mirror-ceph.sh' script is written in Bash and will use rsync to mirror all the contents to a local directory.
Usage is simple:
./mirror-ceph.sh -q -s eu -t /srv/mirrors/ceph
This example will mirror all contents from the source 'eu' which is eu.ceph.com.
The script can easily be run with CRON:
13 1,5,9,13,17,21 * * * /home/ceph/mirror-ceph.sh -q -s eu -t /srv/mirrors/ceph
This will sync from eu.ceph.com on 01:13, 05:13, 09:13, 13:13, 17:13 and 21:13.
If you have spare hardware and resources available you can opt for becoming a mirror source for others.
A few things which are required:
- 1Gbit connection or more
- Native IPv4 and IPv6
- HTTP access
- rsync access
- 2TB of storage or more
- Monitoring of the mirror/source
You can then run the mirror-ceph.sh script and mirror all the contents.
The project wants to analyze the downloads of Ceph a few times a year. From mirrors we expect that they store HTTP access logs for at least 6 months so they can be used for analysis.
Using a DNS CNAME record a XX.ceph.com entry can be forwarded to the server and added to the mirror script.
You can request such a DNS entry on the ceph mailinglists.
