Automatically owned by www-data
To make sure any file or folder you create in /var/www/html gets automatically owned by www-data you can use inotify, it’s like cron but monitors folders/files for changes in attribuets, file creations, modifications and much more.
First install it with:
$ sudo apt-get install incron
Allow root to use incron by opening /etc/incron.allow with:
$ sudo vim /etc/incron.allow
and add root to the file, then save and exit.
Edit your incrontab with:
$ sudo incrontab -u root -e
and add the following line to it:
/var/www/html IN_CREATE /bin/chown -R www-data:www-data /var/www/html/
save and exit.
Now as soon as a file is created in the /var/www/html direcotry it will automatically set onwership to www-data:www-data.
Explanation of the line in incrontab:
/var/www/html is the directory that will be monitored.
IN_CREATE will watch for created files. It’s the file change mask.
/bin/chown -R www-data:www-data /var/www/html/ is the command/action to execute.

- Dump all databases by calling:
mysqldump --extended-insert --all-databases --add-drop-database --disable-keys --flush-privileges --quick --routines --triggers > all-databases.sql - Stop the MySQL server;
- Rename or remove (in case you’ve already backed it up) the MySQL data directory and create an empty one with the same name and permissions;
- Make the appropriate changes in my.cnf;
innodb_file_per_table - Re-initialize the database with the following command (replace the ‘mysqld‘ with the login of the user your MySQL server runs as):
sudo -u mysqld mysql_install_db - Start the MySQL server;
- Get into the ‘mysql‘ console and type:
SET FOREIGN_KEY_CHECKS=0;
SOURCE all-databases.sql;
SET FOREIGN_KEY_CHECKS=1; - Restart the MySQL server.
