篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何在Cloud 9上重新启动MongoDB服务器并关闭终端相关的知识,希望对你有一定的参考价值。
我正在开发我使用MongoDB作为我的数据库,我使用以下命令在云端9上安装终端。
$ 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,我完成后关闭了终端。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:

有些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无效。
答案
您正在启动一个mongod实例,而其中一个已经在后台运行。您可以使用ps -A
查找mongod进程,然后使用kill <process id>
来杀死该实例。
如果该端口被任何其他进程阻止,您可以找到:lsof -i :27017
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
mongod 30284 ubuntu 5u IPv4 447749095 0t0 TCP *:27017 (LISTEN)
