Menyahkod sambungan pangkalan data aplikasi anda: Mencari bantuan

Question

Saya baru menggunakan Php dan baru-baru ini telah ditawarkan bekerja pada beberapa aplikasi (php/laravel) yang berjalan pada pelayan (AWS) menggunakan MySQL dan RDS dengan nginx mengehos kandungan aplikasi/php

Ini ialah fail yang mentakrifkan laluan nginx yang terdapat dalam /etc/nginx/conf.d

Saya mempunyai kod sumber tetapi pekerja bebas sebelum ini telah berhenti bekerja dengan pelanggan. Saya tidak mempunyai kelayakan pangkalan data, saya perlu mengakses pangkalan data tetapi saya tidak boleh. Saya cuba mencari kata laluan daripada fail php dan yang saya dapati hanyalah folder konfigurasi yang mengandungi pangkalan data fail.php dengan kandungan berikut:

Saya telah menyemak pembolehubah persekitaran menggunakan printenv tetapi tidak menemui sebarang pembolehubah persekitaran seperti DB_USERNAME. Memandangkan aplikasi berjalan dengan baik, ia dapat menyambung ke pangkalan data.

Bagaimana untuk mendapatkan kelayakan pangkalan data. Adakah terdapat cara untuk mengetahui cara aplikasi menyambung ke pangkalan data dan berjalan dengan baik?

Answer 1

Dalam direktori akar laravel anda sepatutnya melihat fail bernama ".env", buka fail ini dan anda akan melihat semua pembolehubah contoh laravel di dalamnya

Answer 2

Ini adalah aplikasi PHP/Laravel dan maklumat sambungan disimpan dalam persekitaran pelayan. Logik sambungan pangkalan data adalah sebahagian daripada rangka kerja, anda tidak perlu bermain-main dengannya (ia adalah kod pihak ke-3, bukan sebahagian daripada logik perniagaan)

Dalam sesetengah kes, persekitaran disimpan dalam fail bernama .env (terletak dalam folder akar aplikasi PHP)

Dalam sesetengah tetapan, persekitaran mungkin tiada dalam fail, tetapi ia dicipta semasa penggunaan dan disimpan dengan pembolehubah persekitaran sistem.

Walau bagaimanapun, anda harus mencari pembolehubah persekitaran DB_* untuk mendapatkan bukti kelayakan sambungan pangkalan data, pelayan dan port.
