Initializing the Database

---

Hint - secondary memmbers of a replica set

Secondary members of a replica set do not need to be initialized.

Single System

1. Open a PowerShell (Administrator).

2. Initialize the database:

   & "C:\Program Files\mongosh\mongosh.exe" --tls --tlsAllowInvalidCertificates --tlsAllowInvalidHostnames --eval "rs.initiate()"
   

   The output has to contain the following line:

   "ok" : 1

Proceed with Securing MongoDB: TLS encryption or user authentication.

Replica Set Primary

Caution - replica set primary only

Perform the following configuration steps only on the replica set primary:

1. Open a PowerShell (Administrator).

2. Initialize the cluster on <server_1>:

   & "C:\Program Files\mongosh\mongosh.exe" --tls --tlsAllowInvalidCertificates --eval "rs.initiate({ _id : '<YourReplicaSetName>', members: [{ _id : 0, host : '<Server1>' }]})"
   

   The output has to contain the following line:

   "ok" : 1

Proceed with connecting the database servers to the cluster.
