Setup Mongos Router Server (mongos-router):
After above-mentioned steps, our Shard Config server is good to go. We will now try to start our mongo router process with the Shard Config server.
# create required directories for mongos router $ sudo mkdir -p /srv/mongos-router/logs # start mongodb config server process $ sudo mongos --configdb configrs/dh-mongo-shard-config:27019 --bind_ip 0.0.0.0 --logpath /srv/mongos-router/logs/mongos-router.log --fork
Setup MongoDB Shard Node Servers (mongo-shard-node-01 & mongo-shard-node-02):
We assume that the MongoDB has already been installed with the steps mentioned previously. So we need to make some minor adjustments in order to make it ready for the cluster.
We have to edit /etc/mongod.conf replace the following line:
bindIp: 127.0.0.1
# sharding:
Replace with following:
bindIp: 0.0.0.0
sharding:
clusterRole: shardsvr
Then restart the MongoDB process as follows:
sudo systemctl restart mongod
We have to repeat this process all the shard nodes that we have in the network.
Attach Shard Nodes to the Cluster:
As we are ready with the setup all the required nodes now let’s try to add them into the cluster as mentioned below:
$ mongo localhost:27017
MongoDB shell version v4.0.5
connecting to: mongodb://localhost:27017/test?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("40647d53-afdc-415b-8f8f-b5bc7e826ba8") }
MongoDB server version: 4.0.5
Server has startup warnings:
