Setup replication for monodb by using the following command

[root@linuxhelp ~]# sed -i "s/^#replication:/replication:\n  replSetName: rs01/" /etc/mongod.conf

Now start and enable the mongodb service

[root@linuxhelp ~]# systemctl start mongod

[root@linuxhelp ~]# systemctl enable mongod

Once it is done, check the replication by using the following command

[root@linuxhelp ~]# mongo --eval "printjson(rs.initiate())"
