# Mirroring Ceph
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Guidelines
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Mirror script
|
||
|
|
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:
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
./mirror-ceph.sh -q -s eu -t /srv/mirrors/ceph
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
This example will mirror all contents from the source 'eu' which is *eu.ceph.com*.
|
||
|
|
|
||
|
|
### Running with CRON
|
||
|
|
The script can easily be run with CRON:
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
13 1,5,9,13,17,21 * * * /home/ceph/mirror-ceph.sh -q -s eu -t /srv/mirrors/ceph
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
This will sync from *eu.ceph.com* on 01:13, 05:13, 09:13, 13:13, 17:13 and 21:13.
|
||
|
|
|
||
|
|
## Becoming a mirror source
|
||
|
|
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.
|
||
|
|
|
||
|
|
### Logs
|
||
|
|
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.
|
||
|
|
|
||
|
|
### DNS
|
||
|
|
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.
|
||
|
|
|
||
|
|
### Apache configuration
|
||
|
|
A Apache 2.4 VirtualHost example configuration can be found the Git repository
|
||
|
|
with the name *apache2.vhost.conf*
