How Do I Install GoAccess in Linux?

Presently, the most recent version of GoAccess v1.4 is not available from default system package repositories, so to install the latest stable version, you need to manually download and compile it from source code under Linux systems as shown:

Install GoAccess from Sources in Linux

------------ Install GoAccess on CentOS, RHEL and Fedora ------------ 
# yum install ncurses-devel glib2-devel geoip-devel
# cd /usr/src
# wget https://tar.goaccess.io/goaccess-1.4.tar.gz
# tar -xzvf goaccess-1.4.tar.gz
# cd goaccess-1.4/
# ./configure --enable-utf8 --enable-geoip=legacy
# make
# make install
------------ Install GoAccess on Debian and Ubuntu ------------ 
$ sudo apt install libncursesw5-dev libgeoip-dev apt-transport-https 
$ cd /usr/src
$ wget https://tar.goaccess.io/goaccess-1.4.tar.gz
$ tar -xzvf goaccess-1.4.tar.gz
$ cd goaccess-1.4/
$ sudo ./configure --enable-utf8 --enable-geoip=legacy
$ sudo make
$ sudo make install

Install GoAccess Using Package Manager

The easiest and preferred way to install GoAccess on Linux using the default package manager of your respective Linux distribution.

Note: As I said above, not all distributions will have the most recent version of GoAccess available in the system default repositories..

On RedHat, CentOS, and Fedora
# yum install goaccess
# dnf install goaccess    [From Fedora 23+ versions]
On Debian and Ubuntu Systems

GoAccess utility is available since Debian Squeeze 6 and Ubuntu 12.04. To install just run the following command on the terminal.

$ sudo apt-get install goaccess

Note: The above command will not always provide you the most latest version. To get the latest stable version of GoAccess, add the official GoAccess Debian & Ubuntu repository as shown:

$ echo "deb http://deb.goaccess.io/ $(lsb_release -cs) main" | sudo tee -a /etc/apt/sources.list.d/goaccess.list
$ wget -O - http://deb.goaccess.io/gnugpg.key | sudo apt-key add -
$ sudo apt-get update
$ sudo apt-get install goaccess

How Do I Use GoAccess?

Once you have GoAccess installed on your Linux machine, you can ready to start using it by running the following command. It will first ask you to determine the log format of your access log.

Configure GoAccess Log Format
Configure GoAccess Log Format

The easiest way to get any web server statistics use the flag ‘f‘ with input log file name as shown below. The below command will give you general statistics of your web server logs.

# goaccess -f /var/log/httpd/tecmint.com
# goaccess -f /var/log/nginx/tecmint.com

The above command gives you a complete overview of web server metrics by showing summaries of various reports as panels on a one scrollable view as shown.

    • @Bheema,
      Change the format as shown in the configuration it should work..

      date_format %d/%b/%Y
      log_format %^, %h %^[%d:%^] "%r" %s %b "%R" "%u"
  4. Hi,

    i’ve installed goaccess on my apache machines.. would it be possible to send notification/alert email from goaccess ? .. if not could you suggest me any product (freeware).

  5. Hi

    Is it possible to parse the logs from remote server ie. if i have apache server running in and logs placed in /var/log/apache.log in the same server .is it possible to watch the stats from go access is installed)

    Please help me

    • Anand, I never tried on the remote machine, but you should give a try, if it works for you then it definitely works others too and don’t forget to post your output here, if you’ve tried.

  6. I had the same issue, however, I configured my log format/date in my: ~/.goaccessrc

    color_scheme 1
    date_format %d/%b/%Y
    log_format %h %^[%d:%^] %^ “%r” %s %b “%R” “%u”

  7. Interesting, but the terminal I use captures F10, which prevents specifying the log format. Log format cannot be specified on the command line either.
