Mendapatkan pesan kesalahan ini: sumber daya baca dbModel tidak mengimplementasikan Zend_Db_Adapter_Abstract

Saya meletakkan proyek magento saya di server linux. Pertama, pesan log kesalahan ditampilkan, tetapi folder var tidak terjawab. Kemudian saya membuat folder var, saya memberikan izin 777 dan sama dengan cache, laporan, sesi. Dalam file kesalahan dari folder laporan saya mendapat pesan ini:

Jadi apa yang bisa menyebabkan masalah ini? MENGAPA? dan saya harus menyelesaikannya?

Setelah saya menempatkan koneksi database yang benar saya juga mengubah baris ini:

<disable_local_modules>false</disable_local_modules>

dalam hal ini

<disable_local_modules>true</disable_local_modules>

Saya memberi izin 777 ke folder var secara rekursif menggunakan perintah ini:

chmod -R 777 var

dalam kasus saya

rm -rf var/cache/*

memecahkan masalah - saya mengubah local.xml saya menjadi symlink

dalam kasus saya, saya hanya perlu mengubah izin folder var

chmod -R 777 var

Sepertinya itu adalah masalah cache, Anda perlu menghapus cache, menggunakan itu menggunakan magerun atau menghapus folder cache rm -rf var / cache.

false baris ini hanya menonaktifkan semua modul yang ada di bawah app / code / local / folder.

Jalankan perintah berikut dan nikmatilah!

chown -R username:group var/
chmod -R 777 var/
rm -rf /var/cache/
