simple way:  comment: only installing coturn is enough. 

sudo apt-get install coturn

If you say no, I want the latest cutting edge, you can download source code from their downloads page in install it yourself, example:

sudo -i     # ignore if you already in admin mode
apt-get update && apt-get install libssl-dev libevent-dev libhiredis-dev make -y    # install the dependencies
wget -O turn.tar.gz http://turnserver.open-sys.org/downloads/v4.5.0.3/turnserver-4.5.0.3.tar.gz     # Download the source tar
tar -zxvf turn.tar.gz     # unzip
cd turnserver-*
./configure
make && make install 

sample command for running TURN server:

sudo turnserver -a -o -v -n  --no-dtls --no-tls -u test:test -r "someRealm"

command description:

• -a - Use long-term credentials mechanism
• -o - Run server process as daemon
• -v - 'Moderate' verbose mode.
• -n - no configuration file
• --no-dtls - Do not start DTLS listeners
• --no-tls - Do not start TLS listeners
• -u - user credentials to be used
• -r - default realm to be used, need for TURN REST API
