Installing aria2 on Raspberry Pi

aria2 is a lightweight multi-protocol & multi-source command-line download utility. It supports HTTP/HTTPS, FTP, SFTP, BitTorrent and Metalink. aria2 can be manipulated via built-in JSON-RPC and XML-RPC interfaces. They said.

Installation:

First thing first, always update your repository.

sudo apt-get update

Next, download aria2.

sudo apt-get install aria2

Now, we make a config file for aria2. First, make the directory for it.

sudo mkdir /home/pi/.aria2

And make the config file.

sudo nano /home/pi/.aria2/aria2.conf

Here’s my configuration, you can always configure it yourself using this guide.

dir=/home/pi/downloads
file-allocation=falloc
continue
log-level=error
max-connection-per-server=4
summary-interval=120
daemon=true
enable-rpc=true
rpc-listen-port=6800
rpc-listen-all=true
max-concurrent-downloads=1
disable-ipv6=true
disk-cache=25M
timeout=600
retry-wait=30
max-tries=50

Now, we make aria2 can run on boot. First, make init.d file.

sudo nano /etc/init.d/aria2

Here’s my script:

#! /bin/sh
# /etc/init.d/aria2

### BEGIN INIT INFO
# Provides: aria2cRPC
# Required-Start: $network $local_fs $remote_fs
# Required-Stop: $network $local_fs $remote_fs
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: aria2c RPC init script.
# Description: Starts and stops aria2 RPC services.
### END INIT INFO

RETVAL=0
case “$1” in
start)
echo -n “Starting aria2c daemon ”
umask 0000
aria2c –daemon=true –enable-rpc –rpc-listen-all -D –conf-path=/home/pi/.aria2/aria2.conf
RETVAL=$?
echo
;;
stop)
echo -n “Shutting down aria2c daemon ”
/usr/bin/killall aria2c
RETVAL=$?
echo
;;
restart)
stop
sleep 3
start
;;
*)
echo $”Usage: $0 {start|stop|restart}”
RETVAL=1
esac
exit $RETVAL

Now change aria2’s init.d script permission so it can run as executable.

sudo chmod +x /etc/init.d/aria2

Make aria2 run on boot.

sudo update-rc.d aria2 defaults

Now reboot your Raspberry Pi

sudo shutdown -r now

You can always access aria2 on local network using this webgui provided by ziahamza.
To configure the webgui, go to Setting>Connection Setting.
Enter the host, in this case your Raspberry Pi IP address. And your aria2 port which is inside your aria2.conf, in this case 6800.

Troubleshooting:

1. Download was not successful, download directory are external harddrive
Open aria2.conf and change file-allocation=falloc to file-allocation=none
