Não é possível iniciar o serviço mongodb

Question

Seguindo este guia para instalar o mongodb, mas mongo só não quer começar.

Ao executar sudo systemctl status mongodb , ele mostra apenas Active: failed (Result: exit-code) . Não há saída útil nisso. Como descubro por que não está começando?

Editar:

saída de ls -al /etc/systemd/system/mongodb.service

-rw-r--r-- 1 root root 220 Feb 17 23:59 /etc/systemd/system/mongodb.service

saída de cat /etc/systemd/system/mongodb.service

[Install]

Answer 1

Apenas uma reinstalação simples funcionou.

sudo apt purge mongodb-org*
sudo rm -r /var/log/mongodb
sudo rm -r /var/lib/mongodb
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
sudo apt update
sudo apt-get install -y mongodb-org

e verifique novamente o arquivo de configuração:

sudo nano /etc/systemd/system/mongodb.service

cole isto:

[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

finalmente

sudo systemctl start mongodb
sudo systemctl enable mongodb

também acho que mudei as permissões do arquivo de log para 777
