Configuring MongoDB in a PLOSSYS 5 System

---

Configuring a Shared Replica Set

For the communication with the PLOSSYS 5 system configure a shared replica set:

1. Edit the MongoDB configuration file:

   /opt/seal/etc/mongod.conf
   

2. Change the following line:

   bindIp: 127.0.0.1
   

   to:

   bindIp: 0.0.0.0
   

3. Add the following lines:

   replication:
     oplogSizeMB: 2048
     replSetName: <YourReplicaSetName>
   

   Hint - oplogSizeMB

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

4. Restart the MongoDB:

   mongod

Initializing the Database

1. Initialize the database:

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

   The output has to contain the following line:

   "ok" : 1
