MongoDB在意外崩溃后没有启动

Question

这是我正在做的事情来解决问题，请看看它并告诉我出了什么问题。我删除了 mongod.lock 文件，然后 cd 并运行 ./mongod，但仍然无法正常工作。

oxmat:~ $ cd data
oxmat:~/data $ ls
local/  local.0  local.ns  mongod.lock*  restfull_blogapp/  restfull_blogapp.0  restfull_blogapp.ns  yelp_camp/  yelp_camp.0  yelp_camp.ns
oxmat:~/data $ rm mongod.lock
oxmat:~/data $ ls
local/  local.0  local.ns  restfull_blogapp/  restfull_blogapp.0  restfull_blogapp.ns  yelp_camp/  yelp_camp.0  yelp_camp.ns
oxmat:~/data $ cd ..
oxmat:~ $ ./mongod

消息

ERROR: listen(): bind() failed errno:98 Address already in use for socket: 0.0.0.0:27017

表示某些内容已绑定到端口 27017。这大概是另一个君主实例了。

运行ps -e | grep 'mongo'，看看是否有mongod的过程。例如，我得到输出：

48298 ttys000    1:14.83 mongod

因此，您可以使用该输出中的进程 ID 终止进程。在此示例中，进程 ID 为 48298，因此我以kill 48298终止它

然后再次尝试运行 mongod。

如果由于某种原因，其他某个进程正在使用端口 27017，则可以通过指定--port标志来使用其他端口，如下所示。

./mongod --port 12345
