Server setup sudo nano /etc/nginx/sites-available/default, location / { proxy_pass http://localhost:3000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; }, sudo nginx -t, sudo systemctl restart nginx
27. Mongo wget -qO - https://www.mongodb.org/static/pgp/server-4.2.asc | sudo apt-key add -, echo "deb [ arch=amd64 ] https://repo.mongodb.org/apt/ubuntu bionic/mongodb-org/4.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.2.list , sudo apt-get install -y mongodb-org=4.2.1 mongodb-org-server=4.2.1 mongodb-org-shell=4.2.1 mongodb-org-mongos=4.2.1 mongodb-org-tools=4.2.1
28. Mongo commands sudo service mongod start, sudo service mongod stop, sudo service mongod restart, mongo, sudo systemctl status mongod
29. Mongodb systemctl commands sudo systemctl status mongodb, sudo systemctl stop mongodb, sudo systemctl start mongodb, sudo systemctl restart mongodb, sudo systemctl disable mongodb, sudo systemctl enable mongodb
30. Secure mongo use admin, db.createUser( { user: "AdminOce", pwd: "PWD2018AdminOce", roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] } ), sudo nano /etc/mongod.conf, security: authorization: "enabled", sudo systemctl restart mongod, sudo systemctl status mongod, sudo systemctl enable mongod
31. Check auth mongo, show dbs, mongo -u AdminOce -p --authenticationDatabase admin, show dbs
32. Needed step for admin user use admin; db.grantRolesToUser('admin', [{ role: 'root', db: 'admin' }])
33. Check Link https://medium.com/mongoaudit/how-to-enable-authentication-on-mongodb-b9e8a924efac

35. Strapi npm i -g strapi@latest

Use this after install sudo systemctl enable mongod, sudo systemctl start mongod
Secure using use admin, db.createUser({user: 'UserName', pwd: 'password', roles: [{ role: 'userAdminAnyDatabase', db: 'admin', use admin, db.grantRolesToUser('UserName', [{ role: 'root', db: 'admin' }]), show users, sudo nano /etc/mongod.conf, sudo systemctl restart mongod
