Saya beberapa kali membahas manipulasi Nginx menurut user agent pengunjungnya dan ternyata lupa menjelaskan bagaimana caranya tahu bagaimana cara memperoleh informasinya bagi membedakan akses setiap koneksi ke web server tak hanya dari domisili IP. ? Karenanya, inilah panduan singkatnya. ?
Benar-benar sederhana aslinya, kita hanya perlu mengecek catatan akses milik Nginx, lebih tepatnya file access.log dan saya contohkan gunakan lokasi default berikut:
tail -20 /var/log/nginx/access.logKalau tak ketemu coba cek tempat lainnya.
Nanti hasilnya akan seperti berikut:
