Buat 2 moodle dalam 1 mesin instance

 **buat folder
mkdir -p /var/www/shared/local

**pindah kode
mv /var/www/html/moodle/local/jurnalmengajar /var/www/shared/local/

**buat symlink kepada 2 moodle:
ln -s /var/www/shared/local/jurnalmengajar \
/var/www/situs_a/moodle/local/jurnalmengajar

ln -s /var/www/shared/local/jurnalmengajar \
/var/www/situs_b/moodle/local/jurnalmengajar

**atur permission
chown -R www-data:www-data /var/www/shared/local/jurnalmengajar
chmod -R 755 /var/www/shared/local/jurnalmengajar

**upgrade masing-masing
php /var/www/situs_a/moodle/admin/cli/upgrade.php
php /var/www/situs_b/moodle/admin/cli/upgrade.php

⚠️ HAL PENTING (JANGAN SAMPAI TERLEWAT)
1. Database tetap beda
a → database a
b → database b
👉 supaya tidak merusak data asli

2. moodledata beda
Contoh:
/var/moodledata_a
/var/moodledata_b

3. config.php beda

Cek:
situs_a ; /var/www/situs_a/moodle/config.php
$CFG->dirroot = '/var/www/situs_a/moodle';

situs_b ; /var/www/situs_b/moodle/config.php
$CFG->dirroot = '/var/www/situs_b/moodle';

** SET PERMISSION
chown -R www-data:www-data /var/moodledata_a
chown -R www-data:www-data /var/moodledata_b

chmod -R 755 /var/moodledata_a
chmod -R 755 /var/moodledata_b
