| + | \\ | ||
| + | Create the file " | ||
| + | \\ | ||
| + | \\ | ||
| + | The contents of the key file should be the same as the corresponding file on the | ||

| + | \\ | ||
| + | cat / | ||
| + | Just copy the mongodb.key file from your Controller to your Windows MongoDB folder (C:\Program Files\MongoDB\Server\3.6) | ||
| + | ---- | ||
| + | \\ | ||
| + | ===== Create a MongoDB Service ===== | ||
| + | \\ | ||
| + | From a Windows Command Line, yype the following in Cmd.exe to create a MongoDB Service. | ||
| + | \\ | ||
| + | sc.exe create MongoDB binPath=" | ||
| + | \\ | ||
| + | Start the service with the following command: | ||
| + | \\ | ||

| + | ===== Add Arbiter to Replicaset ===== | ||
| + | \\ | ||

| + | inet6 fe80:: | ||
| + | \\ | ||
| + | | ||
| + | \\ | ||
| + | \\ | ||
| + | If you see the three IP Addresses (Controller IP1, VIP, LicensingVIP) then you are on the PRIMARY controller. | ||
| + | \\ | ||
| + | \\ | ||
| + | Check the password in the secrets.ini | ||
| + | cat / | ||
| + | Now add the Arbiter details by using the following: | ||
| + | mongo admin -u MediaKind -p ********* | ||
| + | \\ | ||
| + | \\ | ||
| + | Add the Arbiter using the rs.addArb method with the IP address of the Windows server that is used | ||
| + | for the management network of the MediaKind appliances e.g. | ||
| + | \\ | ||
| + | repldb: | ||
| + | |||
| + | (where x.x.x.x is the Management IP Address of your nCompass Server) | ||
| + | \\ | ||
| + | ---- | ||
| + | ===== Verify Replicaset Members ===== | ||
| + | \\ | ||
| + | Whilst in the mongo client, use the rs.status method to list the members of the Replicaset: | ||
| + | repldb: | ||
| + | This should return information including details of the PRIMARY, SECONDARY and ARBITER nodes: | ||
