Package Proxy Cache
If you want to install the same Arch packages over and over - like for testing AIF profiles - it could help if you wouldn't have to get the packages every time from the internet. This article shows you how to setup a Squid proxy that only caches arch packages and can be used with aif/pacman/wget/etc with minimal configuration on the client system.
# pacman -S squid
This is the minimum configuration to get squid cache arch packages.
Before defining these rules, remove/comment (if you do not need them) all the default refresh_patterns
refresh_pattern \.pkg\.tar\. 0 20% 4320 reload-into-ims refresh_pattern . 0 0% 0
That should define that *.pkg.tar.* gets cached, and anything else should not.
Objects larger than this size will NOT be saved on disk:
maximum_object_size 256 MB
Set the cache dir and its maximum size and subdirs:
cache_dir aufs /var/cache/squid 10000 16 256
Time to wait until all active client sockets are closed:
shutdown_lifetime 1 seconds
# systemctl start squid.service
or if squid is already running:
# systemctl restart squid.service
Follow Squid access log
To see the access to squid:
# tail -f /var/log/squid/access.log
You should see this for packages that are directed to original host:
and for packages that are delivered from the cache:
Manual Arch Install
Before running /arch/setup, add variables for your proxy. To do so, run on the console:
# export http_proxy='http://your_squid_machine_ip:3128'
# export ftp_proxy='ftp://your_squid_machine_ip:3128'
Now just use /arch/setup to normally install the system, and it should use your proxy. Watch the squid logs to verify this.
