如何在云9上重启MongoDB服务器并关闭终端

Question

我正在进行开发，其中我使用MongoDB作为我的数据库，并使用以下命令在云9上的终端上安装。

$ sudo apt-get install -y mongodb-org 
$ mkdir data
$ echo 'mongod --bind_ip=$IP --dbpath=data --nojournal --rest "$@"' > mongod
$ chmod a+x mongod 
$ ./mongod

这运行得很好，我在完成后关闭了终端。然后我返回到它，我只是输入：$ ./mongod来运行程序，但它给了我以下错误：

有些人建议删除在数据文件中创建的*mongod.lock，然后使用--修复然后运行它，但它仍然不起作用。

在后台已经运行的情况下，您正在启动一个mongod实例。您可以使用ps -A查找mongod进程，然后使用kill <process id>终止该实例。

如果端口被任何其他进程阻塞，您可以通过以下命令找到：lsof -i :27017

COMMAND   PID   USER   FD   TYPE    DEVICE SIZE/OFF NODE NAME
mongod  30284 ubuntu    5u  IPv4 447749095      0t0  TCP *:27017 (LISTEN)
