I have three servers:
- Web-Server
- Database Server
- Database Replication Server
In the upcoming days, I am going to order a SSL certificate for the Web-Server to deliver the data encrypted to the client. This SSL certificate should be enough to also transport the data encrypted to the Database Server.
However, I am also in need of an encrypted connection in regards to the Database Replication Server.
Is it possible to set up the exact same SSL certificate on the Database Server/Database Replication Server? Or will I have to order an extra SSL certificate?
OS: Ubuntu Linux
DBMS: postgreSQL
Reason for encrypting data: Securing data, avoiding MITM attacks, ... (propably every reason for SSL encryption).
WAN: I have three independent vServers. I might move the DB-Servers into a VLAN (intranet) later on but at the moment all servers are running independently at one hoster's network.
