Introduction
Apt-Cache can be used to cache downloaded Debian/Ubuntu packages without the need for additional server configuration, and is very useful for those who have more than two servers.
Requirements
- Debian or Ubuntu
- 10 Minutes time
Installation
Apt-Cache is available in the default Debian/Ubuntu repositories and be installed via apt-get as follows:
apt-get install apt-cacher
Configuration
Apt-Cache accepts all requests by default; as such, we would need to customize its configuration file, /etc/apt-cacher/apt-cacher.conf as follows:
allowed_hosts = <YOUR_SERVER_IP_OR_NETWORK> <YOUR_LAN> <CAN BE * FOR ANY>
daemon_port = <THE_DAEMON_PORT>
To block specific hosts, you can use the denied_hosts directive:
denied_hosts = <BLOCKED_IP>
To apply our changes, we have to restart the daemon as follows:
service apt-cacher restart
Usage
You can now use your Apt-Cacher by editing the /etc/apt/sources.list file on your server. This is how it would look like on Debian Jessie:
deb http://<INSTANCE_IP>:<DAEMON_PORT>/http.us.debian.org/debian/ jessie main
deb-src http://<INSTANCE_IP>:<DAEMON_PORT>/http.us.debian.org/debian/ jessie main
deb http://<INSTANCE_IP>:<DAEMON_PORT>/security.debian.org/ jessie/updates main
deb-src http://<INSTANCE_IP>:<DAEMON_PORT>/security.debian.org/ jessie/updates main
deb http://<INSTANCE_IP>:<DAEMON_PORT>/http.us.debian.org/debian/ jessie-updates main
deb-src http://<INSTANCE_IP>:<DAEMON_PORT>/http.us.debian.org/debian/ jessie-updates main
