sudo服务mongod重新启动：失败

Question

mongodb版本是3.6。我想运行mongodb进行生产，并且确实希望mongodb甚至在关闭终端后也能运行。最初sudo服务mongod start可以正常工作，但是在启用身份验证并通过分配角色添加访问控制后，服务mongod start已经停止工作。

 /etc/mongod.conf.

 # mongod.conf

 # for documentation of all options, see:
 #   http://docs.mongodb.org/manual/reference/configuration-options/

 # where to write logging data.
 systemLog:
    destination: file
    logAppend: true
    path: /var/log/mongodb/mongod.log

 # Where and how to store data.
 storage:
   dbPath: /var/lib/mongo
   journal:
   enabled: true
 #  engine:
   mmapv1:
   smallFiles:true
  #  wiredTiger:

当我使用sudo服务mongod start时；它说启动mongod：失败 但是我的mongod仅在我使用时启动：

  mongod --auth --port 27017 --dbpath /data/db1

我要让mongod服务开始工作。
