无法重新启动mongodb

Question

I am trying to restart my mongodb but it has an error

this is the error:

[root@testdb vagrant]# sudo service mongod restart
Stopping mongod:                                           [FAILED]
Starting mongod: warning: bind_ip of 0.0.0.0 is unnecessary; listens on all ips by default
about to fork child process, waiting until server is ready for connections.
forked process: 6843
ERROR: child process failed, exited with error number 100
                                                           [FAILED]

my config file is:

bind_ip = 0.0.0.0
dbpath = /var/lib/mongodb
fork = true
logappend = true
logpath = /var/log/mongodb/mongodb.log
nojournal = false
pidfilepath = /var/run/mongodb/mongodb.pid
port = 27017
rest = false
smallfiles = false

this is my log

this is the output of ps ax | grep mongod ps ax | grep mongod

1935 ?        Sl     1:53 /usr/bin/mongod --config /etc/mongodb.conf
5592 pts/0    S+     0:00 tail -f /var/log/mongodb/mongodb.log
5889 pts/1    S+     0:00 grep mongod

i also removed /var/lib/mongodb/mongod.lock

when i restart this is the output stop failed.

Answer 1

Most likely either a permissions issue or a incorrect shutdown.

Run commands sudo rm /var/lib/mongodb/mongod.lock to remove the lock on mongod process then chown the directory to the mongod user using

chown-R mongod: mongod /var/lib/mongo then start service sudo service mongod start

Answer 2

Before I try and give my input, here is the MongoDB documentation for processes: http://docs.mongodb.org/manual/tutorial/manage-mongodb-processes/#StartingandStoppingMongo-SendingshutdownServer%28%29messagefromthemongoshell

That being said, trying shutting down the server:

use admin
db.shutdownServer()

and starting it again.

If you're using linux:

mongod --shutdown

I hope this helped a little, or atleast you can try and use the documentation.
