Redirecting to / bin/systemctl start mongod.service

it"s strange that I don"t know what the problem is. Do you have a boss to tell me
you post your installation steps, too. According to the official website, there is no problem with the installation. The official installation package comes with a systemd script
try two solutions
sudo systemctl unmask mongodb
sudo service mongod start or
1 create a profile:
sudo nano /etc/systemd/system/mongodb.service2 copy code
[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
[Service]
User=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf
[Install]
WantedBy=multi-user.target 3 Press ctrl+X to quit
4 start the service
sudo systemctl start mongodb
sudo systemctl status mongodb5 Let it start permanently
sudo systemctl enable mongodb I don't know whether you have solved it or not. It is recommended that you use docker installation
1. Install docker script: $curl-sSL https://get.docker.com/ | sh
2. Install DB script (link parameter is required to back up container data in formal environment, but not in development environment):
$docker run-- name mongoDB-d-P mongo
3. Check the mapped port: docker ps-a
4. Next, turn off the firewall and use the database tool to access
first, I have solved it, second, I followed the official website step by step, and third, I solved it violently. I reset the server and then installed it.
