//錯誤解決：上傳文件時出現 filename is locked 的解決方法解決方法
# cd /var/www/html/nextcloud
# sudo -u www-data /usr/bin/php ./occ files:scan --all
# sudo -u www-data /usr/bin/php ./occ maintenance:mode --on		//開啓維護模式
# mysql -uroot -p'passwd' -D nextcloud -e 'delete from oc_file_locks where 1'
# sudo -u www-data /usr/bin/php ./occ maintenance:mode --off	//關閉維護模式

//調整：修改上傳的顯示條
$ cd /var/www/html/nextcloud/apps/files/js/
$ sudo cp file-upload.js file-upload.js-original
$ sudo vim file-upload.js //在1167行後添加以下內容 進度條顯示爲 已載入/總大小(速度)

//調整：修改新建用戶時顯示的默認文件
//默認文件位置 nextcloud/core/skeleton

//優化：所使用的數據庫爲MySQL但沒有對4字節字符的支持
//相關文檔頁面 https://docs.nextcloud.com/server/18/admin_manual/configuration_database/mysql_4byte_support.html

//修改/etc/mysql/mariadb.conf.d/50-server.cnf文件，標籤[mysqld]的設置
# vim /etc/mysql/mariadb.conf.d/50-server.cnf
