+++ date = 2023-06-08 title = "Inspecting Nginx Logs with GoAccess and MaxMind GeoIP Data" description = "" draft = false +++ # Overview [GoAccess](https://goaccess.io/) is an open source real-time web log analyzer and interactive viewer that runs in a terminal in \*nix systems or through your browser. # Installation To start, you'll need to install GoAccess for your OS. Here's an example for Debian-based distros: ```sh sudo apt install goaccess ``` Next, find any number of the MaxMind GeoIP database files on GitHub or another file hosting website. We're going to use P3TERX's version in this example: ```sh wget https://github.com/P3TERX/GeoLite.mmdb/raw/download/GeoLite2-City.mmdb ``` Be sure to save this file in an easy to remember location! # Usage In order to utilize the full capabilities of GoAccess and MMDB, start with the command template below and customize as necessary. This will export an HTML view of the GoAccess dashboard, showing all relevant information related to that site's access log. You can also omit the `-o output.html` parameter if you prefer to view the data within the CLI instead of creating an HTML file. With the addition of the GeoIP Database parameter, section `16 - Geo Location` will be added with the various countries that are associated with the collected IP addresses. ```sh zcat /var/log/nginx/example.access.log.*.gz | goaccess \ --geoip-database=/home/user/GeoLite2-City.mmdb \ --date-format=%d/%b/%Y \ --time-format=%H:%M:%S \ --log-format=COMBINED \ -o output.html \ /var/log/nginx/example.access.log - ``` ## Example Output See below for an example of the HTML output: ![GoAccess HTML](https://img.cleberg.net/blog/20230608-goaccess/goaccess-dashboard.png) You can also see the GeoIP card created by the integration of the MaxMind database information. ![GoAccess GeoIP](https://img.cleberg.net/blog/20230608-goaccess/goaccess-geoip.png) That's all there is to it! Informational data is provided in an organized fashion with minimal effort.
