$ chmod a+w sites/default/settings.php

Create the Drupal database

To complete the installation, you must create an empty database and a user with full access to the newly created database for Drupal to use. You can do this by command line, or through phpMyAdmin or another database client.

$ mysqladmin -u username -p create databasename

Where ‘username’ is a MySQL user which has the CREATE and GRANT privileges. MySQL will prompt for the ‘username’ database password. Next you must set the access database rights. Log in to MySQL:

$ mysql -u username -p

$ GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER, CREATE TEMPORARY TABLES, LOCK TABLES ON databasename.* TO ‘username’@’localhost’ IDENTIFIED BY ‘password’;

Run the installation script

Why ‘sudo’ command use in linux ?

Posted by Avinash Konanki

In Ubuntu Linux there is not root account configured by default. If users want root account password then they can manually set it up can use ‘sudo’.

‘su’ Vs ‘sudo’

‘su‘ forces you to share your root password to other users whereas ‘sudo‘ makes it possible to execute system commands without root password. ‘sudo‘ lets you use your own password to execute system commands i.e., delegates system responsibility without root password.
