How to setup a Alpine Linux mirror
This document describes how to set up an Alpine Linux mirror and make it available via http and rsync.
- create the dir where we have the mirror
- set up a cron job to sync with master mirror every hour
- set up lighttpd for http access
- set up rsync so other mirrors can rsync from you
Setting up the cron job
Install rsync which will be used to sync from the master mirror.
Save the following file as /etc/periodic/hourly/alpine-mirror
#!/bin/sh # make sure we never run 2 rsync at the same time lockfile="/tmp/alpine-mirror.lock" if [ -z "$flock" ] ; then exec env flock=1 flock -n $lockfile $0 "$@" fi src=rsync://rsync.alpinelinux.org/alpine/ dest=/var/www/localhost/htdocs/alpine/ # uncomment this to only include v1.8 or newer #exclude="--exclude v1.[1-7]" mkdir -p "$dest" /usr/bin/rsync -prua \ $exclude \ --delete \ --timeout=600 \ --delay-updates \ --delete-after \ "$src" "$dest"
Make it executable:
Now it will sync every hour. (given cron runs)
Setting up HTTP access via lighttpd
Install the lighttpd server
Enable dir listings by uncommenting the following line in /etc/lighttpd/lighttpd.conf:
dir-listing.activate = "enable"
Also set cache-control to force cache revalidate every 30 mins. Uncomment mod_setenv in /etc/lighttpd/lighttpd.conf:
Add also the following lines to /etc/lighttpd/lighttpd.conf:
setenv.add-response-header += ( "Cache-Control" => "must-revalidate" )
Start lighttpd and make it start at boot:
Setting up rsyncd
Add the following lines to /etc/rsyncd.conf:
[alpine] path = /var/www/localhost/htdocs/alpine comment = My Alpine Linux Mirror
Optionally set a bandwidth limit in /etc/conf.d/rsyncd. In this example we limit to 500Kbytes/s (approx 5Mbit/s)
