{{Warning| If you want to create an official mirror see [https://wiki.archlinux.org/index.php/DeveloperWiki:NewMirrors this page].}}
 
==STOP==
 
{{Warning|It is generally frowned upon to create a local mirror due the bandwidth that is required. One of the alternatives will likely fulfill your needs. Please look at the alternatives below.}}
 
====Alternatives:====
*[[Network Shared Pacman Cache]]
 
==Local Mirror==
 
===Things to keep in mind:===
* Bandwidth is not free for the mirrors. They must pay for all the data they serve you
** This still applies although you pay your ISP
* There are many packages that will be downloaded that you will likely never use
* Mirror operators will much prefer you to download only the packages you need
* Really please look at the alternatives above
 
'''If you are absolutely certain that a local mirror is the only sensible solution, then follow the pointers below.'''
 
===Server Configuration===
====Building Rsync Command====
* Use the rsync arguments from [https://wiki.archlinux.org/index.php/DeveloperWiki:NewMirrors DeveloperWiki:NewMirrors]
* Select a server from the above article
* Exclude folder/files you do not want by including {{Ic|1=--exclude-from="/path/to/exclude.txt"}} in the rsync arguments. Example contents might include:
<pre>
iso
 
#Exclude i686 Packages
*/os/i686
pool/*/*-i686.pkg.tar.xz
pool/*/*-i686.pkg.tar.gz
 
#Exclude x86_64 Packages
*/os/x86_64
pool/*/*-x86_64.pkg.tar.xz
pool/*/*-x86_64.pkg.tar.gz
</pre>
 
* All packages reside in the pool directory. Symlinks are then created from pool to core/extra/testing/etc..
** As of 9/21/2010 this migration is not yet complete.
*** There may be actual packages, instead of symlinks, in ${repo}/os/${arch}
* Exclude any top-level directories that you do not need
 
Example: {{Ic|1=rsync ''$rsync_arguments'' --exclude="/path/to/exclude.txt" ''rsync://example.com/'' /path/to/destination}}
 
====Example Script====
 
{{Warning|DO NOT USE THIS SCRIPT UNLESS YOU HAVE READ WARNINGS AT THE START OF THIS ARTICLE}}
{{Warning|Only use this script to sync Core/Extra/Community! If you need Testing, gnome-unstable or any other repo, use rsync --exclude instead!}}
 
Yes, this script is partially broken '''ON PURPOSE''' to avoid people doing copy-and-paste to create their own mirror. It should be easy to fix if you REALLY want a mirror.

# Configuration
SOURCE='rsync://mirror.example.com/archlinux'
DEST='/srv/mirrors/archlinux'
BW_LIMIT='500'
REPOS='core extra'
RSYNC_OPTS="-rtlHq --delete-after --delay-updates --copy-links --safe-links --max-delete=1000 --bwlimit=${BW_LIMIT} --delete-excluded --exclude=.*"
LCK_FLE='/var/run/repo-sync.lck'
# Make sure only 1 instance runs
if [ -e "$LCK_FLE" ] ; then
OTHER_PID=`/bin/cat $LCK_FLE`
echo "Another instance already running: $OTHER_PID"
exit 1
fi
echo $$ > "$LCK_FLE"
for REPO in $REPOS ; do
echo "Syncing $REPO"
/usr/bin/rsync $RSYNC_OPTS ${SOURCE}/${REPO} ${DEST}
done
# Cleanup
/bin/rm -f "$LCK_FLE"
exit 0
 
====Another mirror script using lftp====
lftp can mirror via several different protocols: ftp, http, etc. It also restarts on error, and can run in the background. Put this into your $PATH for an easy way to mirror that continues if you log out.
 
#!/usr/bin/lftp -f
lcd /local/path/to/your/mirror
open ftp.archlinux.org (or whatever your favorite mirror is)
# Use 'cd' to change into the proper directory on the mirror, if necessary.
mirror -cve -x '.*i686.*' core &
mirror -cve -x '.*i686.*' extra &
mirror -cve -x '.*i686.*' community &
mirror -cve -x '.*i686.*' multilib &
lcd pool
cd pool
mirror -cve -x '.*i686.*' community &
mirror -cve -x '.*i686.*' packages &
 
if you want to see the current status of the mirror. open lftp on terminal and type 'attach <PID>'
 
====Partial mirroring====
 
Mirroring only some repositories is definitely not easy, due to the centralization of most packages in `pool/`.
See [http://blog.invokk.net/2012/01/mirroring-only-some-repositories-of-archlinux/ this blog post] for an attempt at writing a script for this task.
 
====Serving====
*HTTP (LAN)
**[[LAMP]]
**[[Lighttpd]]
*FTP (LAN)
**[[vsftpd]]
*Physical Media
**Flash Drive
**External HD
 
===Client Configuration===
*Add the proper Server= variable in /etc/pacman.d/mirrorlist
*For physical media (such as flash drive) the following can be used: Server = file:///mnt/media/repo/$repo/os/$arch (''where /mnt/media/repo is directory where local mirror located'')
