Creating the OwnCloud database

OwnCloud can use a variety of databases. We will be using MySQL. The database can be created as follows :

# mysql -u root -e \
  "CREATE DATABASE IF NOT EXISTS owncloud; \
  CREATE USER IF NOT EXISTS 'owncloud'@'localhost' IDENTIFIED BY 'password'; \
  GRANT ALL PRIVILEGES ON *.* TO 'owncloud'@'localhost' WITH GRANT OPTION; \
  FLUSH PRIVILEGES;"
#

It is also possible to create user owncloud@localhost and database from phpmyadmin.

setting up the owncloud database

The admin user is the one who will manage the other users and OwnCloud from the OwnCloud web page.

# occ maintenance:install \
    --database "mysql" \
    --database-name "owncloud" \
    --database-user "owncloud" \
    --database-pass "password" \
