The Apache Software Foundation has mirror sites from all around the world, but we are always looking for more reliable and well connected sites that can help us distribute our software. We no longer encourage mirrors for the various Apache Software Foundation websites, since they have become too complicated to be easily replicated. Instead, we request mirrors that can aid in distributing the software itself by mirroring our main software distribution directory.
We have a few requirements for those wishing to run a mirror:
In addition, we require that you run the Apache HTTP Server version 1.3.26 or 2.0.43 or later and use the following configuration for your web mirror to allow all the features of our download site to function optimally:
<Directory /path/to/mirror> IndexOptions FancyIndexing NameWidth=* FoldersFirst ScanHTMLTitles DescriptionWidth=* HeaderName HEADER.html ReadmeName README.html AllowOverride FileInfo Indexes Options Indexes SymLinksIfOwnerMatch FollowSymLinks ErrorDocument 404 default </Directory>
Please note that our HEADER.html files do not contain the HTML pre-amble, so it is important that the option SuppressHTMLPreamble is not enabled.
Please ensure that the server does not send a Content-Encoding header for any of the compressed archives.
The hashes and signatures used to check downloads are created for the compressed archives so it is vital that the browser is not told to decompress them.
.tgz files are compressed TAR files.
They should have suitable Content-Type - e.g.
application/x-gzip - but no Content-Encoding should be sent.
If the server incorrectly sends
Content-Encoding: x-gzip (for example), many browsers will automatically decompress the response.
This produces a TAR file which will not verify when checked against the hashes or sigs.
We do add ftp mirrors to our list, but we much prefer http mirrors and we select only http mirrors as "preferred" mirrors.
We only support rsync for updating mirrors.
You can find details on rsync at http://rsync.samba.org/. Update your mirror with :
rsync -avz --delete --safe-links rsync.apache.org::apache-dist /path/to/mirror
If you wish to exclude resource-intensive projects, replace
::apache-dist-most. Do not use
(At the time of writing, the
was 68GB and the
::apache-dist-most module a 35GB subset of it.)
If there is a problem with file/directory permissions,
make sure you use a proper
umask in your cronjob :
umask 022 ; rsync ...
Please don't rsync "on the hour" (cronjob minute 0) ; pick a random minute between 5 and 55. Never run cronjobs at minute 0 unless the nature of the job requires it.
Also note that you should run the job twice a day or at most 4 times a day
Please note: older versions of this page (June 2011 and before) said to use the options '-rtlzv'. This was wrong, because the '-p' (preserve permissions) option was missing. Please ensure you use '-avz'. The '-a' (archive mode) option includes the '-p' option.
Please ensure that you regularly check the output from the rsynch job so you can detect problems like lack of disk space or permission issues. Thanks.
You can add sponsor information (only) as follows :
The contents of
README.html will appear near the bottom of your mirror's
Please note that only the home-page (top-level) README.html may be customized in this way; all other README.html files must be mirrored unchanged. Don't omit the '/' in "/README.html".
Please limit the contents of the README.html to something like This mirror is donated by www.domain.com [url] to support the Apache open source community. Refering to specific services or products may be seen as PageRank manipulation by search engine companies and may have an adverse effect on your site's ranking.
It has been noted that certain sites redirect 404 pages as a form of extra advertising or traffic booster. We will remove mirrors that do this from our list and then send an email to the maintainers address. The top level /README.html file as mentioned above is the ONLY local alteration of any part of the mirror we accept for you to provide Sponsor Information.
We sometimes get requests to add mirrors that are not working correctly. Please check at least the following:
Once the site is configured, tested, and updating consistently, you should subscribe to the mirror maintainers mailing list by sending an mail to "email@example.com".
If possible, please use an alias like firstname.lastname@example.org for the contact address rather than a personal e-mail address. To subscribe the alias address, send the email to "email@example.com".
Then you can provide us with details of your mirror by submitting them to our Issue Tracker.
You'll need to sign up for an account, then create a new issue in project "Infrastructure (INFRA)" with component "Mirrors".
Please include the following information in the Description field:
We only use the IP to check the logs before we add the mirror to the list. Once your mirror is on the list, you can change the IP of the mirror without notifying us.
If you have any questions, please feel free to raise them in your issue tracker ticket (component "Mirrors") or on the mirror maintainers public mailing list firstname.lastname@example.org. You don't need to subscribe in order to post (but a short note in your signature that you request replied to be CC'd to you would help).
