change default locations of website data and miradb data directory

I am building a machine and would like to have ISPCONFIG running on it. I have the following drives on the machine

1 500 GB for the OS and ISCONFIG - OS is Ubuntu 18.04LTS
1 10TB Drive for holding websites
1 1TB drive for holding the databases

How do i go about setting things up so that everything gets to the correct places

the 10TB drive is mounted as /website-data
the 1TB drive is mounted as /database-data

 

since this is a clean install, as i am going to install later this afternoon, i would do this before i do an installation, correct ?

 

what about premissions? will i have to do anything about that. I am very new at linux so sometimes i have to have things spelt out for me.

 

A straightforward way to get what you want is set up mounts during Ubuntu install. I have not installed Ubuntu in this way, but I know Debian does allow this. So maybe Ubuntu server version and some advanced installation mode at least allows choosing mount points for disk partitions.
That is: Install Ubuntu following the Tutorial:
https://www.howtoforge.com/tutorial/ubuntu-lts-minimal-server/
When you to the Partition Disks phase, choose Manual and mount your disks as follows:

• 500 GB disk as / and put also swap there
• 1 TB disk as /var/lib/mysql
• 10 TB disk as /var/www

This way permissions are set up by OS install and ISPConfig install, like all other thing also.
