While installing wiki.js in the configure window, wiki.js is unable to connect to mongodb and mongodb is unable to start the service. Executing this command wont give any error:
systemctl start mongodb.service;
systemctl enable mongodb.service
While, systemctl start mongod pops an error message saying:
Failed to start mongod.service: Unit mongod.service not found
in the configure window it shows:
Error: failed to connect to server [localhost:27017] on first connect [MongoError: connect ECONNREFUSED 127.0.0.1:27017]
How to resolve the issue?
