How to set up an apt-cacher server?
Solution 1
From Apt-Cacher-Server:
Server side configuration.
- Install apt-cacher and apache2 webserver on the system that you want it to host:
sudo apt-get install apt-cacher apache2
. Remove apache is you already have that running. - Enable apt-cacher:
sudo gedit /etc/default/apt-cacher
.Change autostart to 1 - If apache is already installed before installing apt-cacher:
sudo invoke-rc.d apache2 restart
. You should be able to accesshttp://server:3142
now. -
/etc/apt-cacher/apt-cacher.conf
contains all the settings. Adjust them to your needs. - Import local cache:
sudo /usr/share/apt-cacher/apt-cacher-import.pl /var/cache/apt/archives
- Mount the installer CD:
sudo mount -o loop /home/username_or_other_path/ubuntu-9.10-rc-alternate-i386.iso /media/cdrom0
and import the CD cache:sudo /usr/share/apt-cacher/apt-cacher-import.pl -R -r /media/cdrom0
.
Client side configuration:
- Sources.list: change all the URLs to point to your servers URL.
(ie.
deb http://apt-cacher-server:3142/archive.ubuntu.com/ubuntu/
) (change 1 client and if it works copy it over to all other systems)
2a. Use as a proxy to APT: Static configuration. In a terminal, type:
sudo nano /etc/apt/apt.conf.d/01proxy
Add:
Acquire::http::Proxy "http://<IP address or hostname of the apt-cacher server>:3142";
2b. Use as a proxy to APT: Roaming configuration: see the link at the top for setup and script.
untested by myself but someone at work used this page to set it up for ourself.
edit: About the error: apparently Perl’s rename function can’t move files across devices, and that’s how the imports and cache laid on the disk.
Options: 1. use the -s parameter (only creates symlinks). 2. Manually move the files onto the same device before importing.
Solution 2
I never got any of those apt-cachers working right, so I asked Michael Vogt if we could ship an easy to use squid configuration for exactly this, and squid-deb-proxy was born.
It's very easy to set up and requires no config on the client part apart from installing the client package.
Instructions for how to use it are here:
Solution 3
I think a transparent proxy, like Squid would do the job easily.

I have more than 500 systems running ubuntu 10.04, ubuntu 10.10 and ubuntu 11.04. It is difficult for us to install new packages to these machines from internet, because of the high bandwidth usage. I am planning to set up an apt-cacher server, such that it should install packages from a local machine, instead of installing packages from the internet. Can anyone give me a neat solution please? Thanks in advance.
Error in server configuration:
root@karthick:~# sudo /usr/share/apt-cacher/apt-cacher-import.pl /var/cache/apt/archives Importing: acl_2.2.49-3_i386.deb Failed to rename acl_2.2.49-3_i386.deb. Try read-only (-r) or symlink (-s) options. at /usr/share/apt-cacher/apt-cacher-import.pl line 154.
Error in client on installing packages
Can anyone sort out pls?

karthick87 almost 13 yearsThanks a lot for the brief explanation. As i said already i have ubuntu 10.04,10.10 and natty. So if i install some packages in natty it should install packages from the local natty source and if i install some packages in ubuntu 10.04 it should install packages from the local 10.04 source. Will it happen like that? Or i want to setup 3 apt-cacher server? like one for ubuntu 10.04 and another for 10.10 and the last one for natty ?

karthick87 almost 13 yearsWhat version of ubuntu you use for apt-cacher server ?
-
Rinzwind almost 13 yearsWe use Maverick.
-
karthick87 almost 13 yearsUbuntu - 10.10 Server edition right ?
-
Rinzwind almost 13 yearsWe use the desktop edtion but it does not really matter wich you use: it basically is set around apache so what OS it relies upon should not really matter.
-
karthick87 almost 13 yearsI want cross check the setup, to findout whether the setup is working or not. How do i do that?

karthick87 almost 13 yearsHow to set cd cache with latest updates?
-
Rinzwind almost 13 yearsI do not get your q. Sorry... the cd cache is taking so you do not need to download these files from the web (it's alot quicker this way). Updates will happen automatically when you update your system (???)
-
karthick87 almost 13 yearsFine, thanks a lot. Can you please provide the link for downloading the CD cache for the ubuntu version 10.10 ?
-
Rinzwind almost 13 yearsThis should cache the cd contents (for any release) sudo /usr/share/apt-cacher/apt-cacher-import.pl -R -r /media/cdrom0 (it's only to not have to download the whole cd content from the ubuntu servers)
-
karthick87 almost 13 yearsI am getting an error on entering a particular command. Pls see the updates in my question.
-
Rinzwind almost 13 yearsI found the same error mentioned here: mummila.net/nuudelisoppa/2009/08/15/… and put it in the answer!

karthick87 almost 13 yearsWhich files i have to move and to which location?

Ehtesh Choudhury over 10 years+1. Definitely along the lines of zero-configuration.
squid-deb-proxy
is fantastic and for the average user, should be preferred overapt-cacher
and friends.
