这就是我要解决的问题请查看并告诉我出了什么问题。我删除了mongod.lock文件然后cd回来并运行./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

library(data.table)

df<-data.table(df)
small.set<-df[.(gender==1,ethnicity == 1,group == 1)]

意味着某些东西已绑定到端口27017.它可能是另一个mongod实例。

运行ERROR: listen(): bind() failed errno:98 Address already in use for socket: 0.0.0.0:27017以查看是否存在mongod进程。例如，我得到输出：

ps -e | grep 'mongo'

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，因此我使用48298 ttys000 1:14.83 mongod

终止它

然后尝试再次运行mongod。

如果由于某种原因，某些其他进程正在使用端口27017，那么您可以通过指定kill 48298标志来使用不同的端口，如下所示。

--port

mongodb在意外崩溃后没有启动
