Karena error tersebut Nextcloud menjadi login loop, tidak bisa masuk login, setelah memasukkan username/password akan kembali ke halaman login lagi.
Ketika login di Nextcloud statusnya 303
Akar Masalah
Bila dilihat dari masalah tersebut error yang terjadi karena session tidak bisa disimpan/dipanggil. Karena Nextcloud berbasis PHP maka pada dasarnya menggunakan session dari PHP kecuali anda menggunakan redis atau memcache.
Yang harus ditelusuri adalah session PHP, cek nilai ‘session.save_path’ di php.ini atau www.conf. Di CentOS bisa dilihat di /etc/php-fpm.d/www.conf
$ grep session /etc/php-fpm.d/www.conf ; (error_log, sessions.save_path, ...). ; at http://php.net/session.save-path php_value[session.save_handler] = files php_value[session.save_path] = /var/lib/php/session
bawaannya session PHP di Centos di set sebagai user apache, cek dengan ls -lah /var/lib/php/session
total 8.0K drwxrwx--- 2 root apache 4.0K Nov 14 04:09 . drwxr-xr-x 6 root root 4.0K Mar 24 12:49 ..
bila anda menjalankan php-fpm sebagai user lain, harus di set permissionnya sebagai user tersebut. Contoh saya menjalankan nginx dan php-fpm sebagai user www-data, maka disini saya rubah permissionnya menjadi milik user www-data dan group www-data
chown www-data:www-data -R /var/lib/php/
restart PHP FPM
systemctl restart php-fpm
coba login ke Nextcloud.
Bila anda lebih memilih login dengan cli (curl), gunakan format
curl -u user:password -H 'OCS-APIRequest: true' https://cloud.nextcloud.com/ocs/v2.php/cloud/user
contoh
curl -u jaranguda:dWdCd3NVnqoM7Cq39z4N -H 'OCS-APIRequest: true' https://cloud.jaranguda.com/ocs/v2.php/cloud/user
keterangan :
username : jaranguda
password : dWdCd3NVnqoM7Cq39z4N
domain nextcloud : cloud.jaranguda.com
output dari perintah diatas
<?xml version="1.0"?> <ocs> <meta> <status>ok</status> <statuscode>200</statuscode> <message>OK</message> </meta> <data> <storageLocation>/var/www/nextcloud/data/jaranguda</storageLocation> ... ... ...
sukses login.
