Documentation

What are the PHP-FPM, Nginx, MariaDB and Varnish Locations?

The locations for each of the Pinch components are as follows:

  • Nginx: /etc/nginx
  • PHP-FPM: /etc/php-fpm.d/
  • MariaDB: /etc/my.cnf.d/
  • Varnish: /etc/varnish/ & /etc/sysconfig/varnish/

What is the Username and Password of my system?

Pinch creates a new privledged user for your system and disables root SSH logins for security. Additionally, it will set a root password for your MariaDB server.

  • Hostname Option: host.domain.com
  • Timezone Option: Australia/NSW
  • New SSH Port: 3636
  • New Root Username: sudoninja
  • New Root Password: sudoninjapassword
  • MariaDB Root Password: mariadbpassword

For example, you can now login using ssh -p 3636 [email protected] with the password sudoninjapassword.

You can adjust the defaults by modifying the parameters in the install.sh script, located in the vanilla-lemp folder. Alternatively, if you are using the Linode stack-script, you will be prompted to enter these options on rebuild.
