mongodb - 如何重启 MongoDB 服务器并关闭 Cloud 9 上的终端

Question

我正在开发中，我使用 MongoDB 作为我的数据库，我使用以下命令在云 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

这很好用，完成后我关闭了终端。然后我回到它，我只是输入:$ ./mongod 以运行该程序，但它给了我以下错误:

有人说要删除在数据文件中创建的*mongod.lock，然后使用--repair 然后运行它，但它仍然不起作用。

Answer 1

当一个 mongod 实例已经在后台运行时，您正在启动一个 mongod 实例。你可以使用 ps -A寻找 mongod 进程，然后使用 kill <process id>杀死那个实例。

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

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