Mandatory Configuration Steps for Relay Server¶

Configure a Shared Replica Set¶

In MongoDB, a shared replica set has to be configured:

Open the MongoDB configuration file:
```
/opt/seal/etc/mongod.conf
```
Add the following lines:
```
replication:
  oplogSizeMB: 2048
  replSetName: p5
```
Hint - oplogSizeMB

We recommend setting oplogSizeMB to 5 % of the disk space available for MongoDB.

Restart the following service:

plossys service stop seal-mongodb
plossys service start seal-mongodb

Initialize the Database¶

You have to initialize the database after configuring the shared replica set.

Initialize the database:

sudo mongo --ssl --sslAllowInvalidCertificates --sslAllowInvalidHostnames --eval "rs.initiate()"

Change the Printer Name (Only if `relay-printer` Already Exists in PLOSSYS 5)¶

The name of the relay printer must not match any printer name available in the target PLOSSYS 5 system! If a printer called relay-printer already exists in the PLOSSYS 5 system, execute the following steps:

In the printer configuration file, relay-printer.yml, change the printer name relay-printer to a new name.
In the server configuration file, relay-server.yml, replace relay-printer by the new printer name.

Import the System Configuration¶

Open the system configuration file, relay-server.yml, in the installation directory of Relay Server.
Replace all occurrences of <username> and <passsword> by an user name and password.
Save your changes and close the file.

Import the system configuration:

plossys config import relay-server.yml --insecure

Import the Printer Configuration¶

Open the printer configuration file, relay-printer.yml, in the installation directory of Relay Server.
Replace all occurrences of <remote-plossys-server> by the server name or IP address of the target PLOSSYS 5 system. All output jobs received by the Relay Server will be forwarded to this system.
Save your changes and close the file.
Import the printer configuration. Replace <username> and <password> by the values specified when importing the system configuration:
```
plossys printer import relay-printer.yml --insecure --user <username> --pass <password>
```
