1.5) Prerequisites to start WordPress

  • Start httpd server

     sudo /usr/sbin/httpd -D BACKGROUND
    • Ubuntu (16.04, 18.04, 19.04)
     sudo service apache2 start

  • Start MySQL service

  • Create database and grant privileges to 'Wordpress' user

    Note: First two commands will prompt for password. Press Enter if the password for root user is not set.

    sudo /usr/bin/mysql  -h <DB_HOST> -uroot -p -e "create database WORDPRESS" && sudo /usr/bin/mysql -h <DB_HOST> -uroot -p -e "create user 'Wordpress'@'localhost' identified by 'password'" 
sudo /usr/bin/mysql  -h <DB_HOST> -uroot -p -e "grant all privileges on WORDPRESS.* to 'Wordpress'@'localhost' identified by 'password' with GRANT OPTION"

Note: After starting Apache httpd Server and MySQL Service, direct your Web browser to the WordPress Admin Console at http://<HOST_IP>:<PORT>.
