How do I remember all my threads? I authored them, so I maintain a basic familiarity with them. Plus, if you test your methods and author an instructional post, sometimes it takes 15 min+ to test it ahead of publication. So I'm apt to remember a post that took some doing!
25MB is not overly large for an access log. Your error log, on the other hand, is rather large if it's >500MB. Do you have logrotate enabled to process all your domlogs?
Not sure what you're encountering, because I tested both methods when I posted to the other thread. Maybe something particular with your installation? Try the other method using the legacy geoip -- same as what the current GoAccess uses:
yum -y install geoip-devel
cd /usr/local/src
wget https://tar.goaccess.io/goaccess-1.9.3.tar.gz
tar -xzvf goaccess-1.9.3.tar.gz
cd goaccess-1.9.3/
./configure --prefix= --enable-debug --enable-utf8 --enable-geoip=legacy --with-getline --with-openssl
make
make install
