First you will have to install the needed dependencies based on your Linux distribution:

# apt-get install libncursesw5-dev libglib2.0-dev libgeoip-dev libtokyocabinet-dev

For Fedora/RedHat/CentOS Linux distribution you can install them like this:

# yum install ncurses-devel glib2-devel geoip-devel tokyocabinet-devel

Next you can go to GoAccess Download website to get the latest version and download it using wget. After that you just need to decompress it and install it using the usual: ./configure, make and make install, like this:

# wget http://tar.goaccess.io/goaccess-0.8.3.tar.gz
# tar zxvf goaccess-0.8.3.tar.gz
# cd goaccess-0.8.3/
# ./configure --enable-geoip --enable-utf8
# make
# make install

goaccess install

How to Use GoAccess

To use GoAccess you will have to use the command with the -f option pointing to the log file like this:

Each report is pretty self-explanatory, you have unique visitors count, requested pages, 404 not found errors, hosts, OSs, browsers and location the visitors have, referrals from other sites or search engines. The main idea behind GoAccess is being able to quickly analyze and view web server statistics in real time, so it provides a fast way too look at those different statistics.

You could also generate a HTML report if you wish so using the following command:

# goaccess -f access.log -a > report.html

GoAccess is a nice utility to have around for when you need a fast view on what is currently happening, it does not provide a lot of details like AWStats, but it's fast and easy to setup and use.
