Installing Mare Server on Ubuntu 20.04 Server LTS

Important

You will need a valid Certificate for the server.
Set one up using LetsEncrypt or use the one provided by your hoster
The server provided is only guaranteed to run under Ubuntu 20.04 Server LTS. For anything else, you are on your own. The server is provided as a standalone .NET application which does not require .NET Core to be installed.

Copy files over

Connect via SCP and copy over all files to some directory
The directory will need to be writeable by the user

Install MSSQL Server 2019 CU

Import GPG keys

sudo curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

Add repository

sudo add-apt-repository "$(curl https://packages.microsoft.com/config/ubuntu/20.04/mssql-server-2019.list)"

Run configuration
```
sudo /opt/mssql/bin/mssql-conf setup
```
Install "3) Express"
Set a password

Verify server is running

systemctl status mssql-server --no-pager

Optional: set up a separate user for Mare Synchronos
- I'll let you figure that out yourself
- The user will need database creation rights

Configure Mare Server

open provided appsettings.json
edit DefaultConnection to "Server=localhost;User=sa;Password=<sa password>;Database=mare;MultipleActiveResultSets=true"
- if you created a separate user for mare on the SQL Server, specify the username and password here
edit CacheDirectory and set it to a path where the file cache is supposed to be located. i.e. /home/<user>/servercache
- you will also need to create that folder
optional: set Port under edit Url and change the +:5000 to +:<your port>
- Set up Certificate
- Set Path to the certificate file path
- Set Password to the password of the certificate
  - If the certificate file is split in private key and public, set KeyPath to the private key file
- Delete all unused keys from Certificate
