So mongo was running fine, and then I tried to create a database and a collection. Long story short, the server stopped responding. I thought (after about 6 hours of trying everything else, asking my friends and getting literally nowhere) that maybe I should just uninstall and reinstall mongoDB. Turns out that was a mistake, because now when I try to do the mongo command I get this
$ mongo
bash: /c/Program Files/MongoDB/Server4.4/bin/mongo.exe: No such file or directory
I noticed that there is no "/" between Server and 4.4 --- I think that's the issue, but I have no idea how to fix that. An yes, I have added MongoDB to my system variable path...
What is going on here?
It seems like commands are working now. I guess I just needed to wait like 8 hours!?

We just migrated our infrastructure on AWS from one account to another.
The mongo version installed on the server is 2.4.9
I am new to MongoDb and faced the following 2 errors when I ran the web app -
{"name":"MongoError","errmsg":"exception: FieldPath field names may not start with '$'.","code":16410,"ok":0}
and
{"name":"MongoError","errmsg":"exception: the $cond operator requires an array of 3 operands","code":16019,"ok":0}
The web app was working on our previous instances. Can anyone point me in the right direction?
Upgrading to the latest mongodb (3.0.2) helped resolve this issue for me.
P.S. - Make sure you kill the mongod process already running using killall -15 instead of pkill -9 as the latter could cause damage.
I have a collection with about 3,000,000 entries that I need to reindex. This whole thing began when I tried to add a 2d index. To do this, I created an ssh tunnel, opened the mongo shell and tried to use ensureIndex. I'm in a place with a somewhat unreliable internet connection, and an hour in it ended up breaking the pipe. I then tunneled back in, opened the mongo shell and tried to look at the number of indexes using getIndexes; the new index I created showed up, but I wasn't confident it had finished, so I decided to use reIndex. In retrospect, this was stupid. The pipe broke again. Now when I open the shell and try to issue getIndexes, the shell doesn't respond.
So what should I do? Do I need to repair my database? Can I issue reIndex when I have a more reliable internet connection? Is there a way to issue reIndex without keeping the shell open, but without doing it in the background and having it take eons? (I'll check the mongod shell options to see if I can find anything, then check the node.js mongo api so I can try running something as a service on server)
And also, if I end up running reIndex as a service on the server, is there any way to check if it's working? The most frustrating part of this right now is I have no idea if my database is ok, if reIndex is still running, etc. Any help would be much appreciated. Thanks.
You don't have a problem. Mongo runs commands and only stops them if you explicitly kill the operation (db.killOp()).
You do not need to wait for the index operation to finish!
Regarding the connection problems, try using the screen command.
It enables you to create a "persistent" screen - not in the way of disk persistence, but in the means of connection-loss.
I was trying to run Meteor on my VPS and I was getting this error:
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Unexpected mongo exit code 100. Restarting.
Can't start Mongo server.
MongoDB had an unspecified uncaught exception.
This can be caused by MongoDB being unable to write to a local database.
Check that you have permissions to write to .meteor/local. MongoDB does
not support filesystems like NFS that do not allow file locking.
I have figured out that the problem is in my user permissions or something like that. It works very smoothly when I try to run meteor with root access. If I try to run meteor with my "custom" user, it fails. Even though I grant him sudo privileges as listed on DigitalOcean. Why is it so? What is the problem behind?
I am on Ubuntu 14.04.1 LTS. Meteor is version 0.8.3 and I am using MongoDB coming with Meteor. I do not have seperated instalation of MongoDB.
Update: Basicly I have found the problem but I still do not now what is causing the problem. I am on DigitalOcean VPS. If I run Meteor over SSH, it fails. If I run Meteor on web Console Access, it works. I do not get it.
Answer https://stackoverflow.com/a/15752736 helped me to find out that Mongo doesn't want to start without properly set locale.
Try to run export LC_ALL="en_US.UTF-8" command before meteor command.
WARNING: This deletes the database and all of the application's data.
rm -rf .meteor/local
Solved it for me when none of the above solutions did.
I would guess that the custom user you created cannot remove the mongod.lock file due to insufficient premissions.
Also check that you have space on your HD, That was my problem.
I just got mongo running yesterday, I entered C:\mongodb\bin\mongod.exe, then bought up another command prompt and entered the same thing again, and it was working fine. I ended up shutting it down wrong and now im getting unable to create/open lock file: data/db/mongod/lock because it is being used by another process. I have tried all of what im seeing but getting not recognized errors. It was a little test db, so i want to just get rid of it so i can open mongo again. I deleted the file.lock from my db file as well, but not sure it worked seems like it left and was back again, but it might just be me.
I know this is a super easy problem, just not getting it. Where should i be entering these command, im following the instructions, but i know im not inputing them in the right place because none of them work at all. I tried just inputting them, in C, in C: data/db, i entered C:\mongodb\bin\mongod.exe left it open and opened another command prompt and enter everything in there to. I can't just reset mongodb? Does anyone know what I'm missing maybe it's i have no windows knowledge at all, i'm trying to use it because i know javascript a little php/sql and i'm trying to learn node.js when i had it working in the shell it was great, but with this set up stuff i'm lost. I'm understanding everything there saying but just not where to do it i think.
Someone please lol, i just uninstalled mongodb and reinstalled and same problem.
mongod --repair (is not recognized as internal, or external command)
db.repairDatabase(same,,is not recognized as internal, or external command);
\data\db\mongod.lock (asks how i want to open it)
This is my set up, i think mongod is the problem, but can't get rid of it.
Computer>Windows>data>db
_tmp
joural
local
local.ns
mongod locked file
edit*** not sure if i removed the lock or not but i got it to work. I should have wrote down how i did it but pretty sure this was it.
open a command prompt cd\ enter it cd mongodb\bin enter it open another command cd\ enter it cd mongoDb\bin enter it. in the first command enter mongod then in the other one enter mongo. Don't know if this is right way, but i got me to be able to play with mongodb like i wanted.
try to remove mongod.lock and journal, then restart.
I am trying to install the Sphinx Search Server. I followed the steps given here http://itsonrail.wordpress.com/2010/05/23/installing-sphinx-on%C2%A0windows/
I added C:\Sphinx\bin to environment path and Sphinx Search is listed in the Services panel. When I try to start it, this error occurs:
Windows could not start SphinxSearch service on local computer
Error: 1067 The process terminated unexpectedly.
Please help me solving this problem. Thanks in advance.
I trid this http://sphinxsearch.com/forum/view.html?id=2684 but it didn't help.
I had the same error in my Windows 7 x64. The step below helped to solve my problem:
Create folders data and log in C:\Sphinx.
Then try to start sphinx with cmd:
C:\sphinx\bin>searchd
I have faced the same problem and eventually moved the sphnix.conf to C:\Sphinx\bin\sphnix.conf from root and the services starts. Please try this. (Please make sure there are data\, log\ directories in the root with write permission)
It is looking like your configuration is not setup properly. Have you tried to run search daemon from sphinx directory path via command prompt?
C:\sphinx\bin> searchd
C:\sphinx\bin>indexer --rotate –all
Also please ensure the log via search.log or windows event log.
If it is not running after this than try to reinstall it again
I hope it will work for you
Error 1067 doesn't say much about the problem, except that the process terminated unexpectedly. Try looking some more informations in searchd.log.
I've got same error code when I tried to update Sphinx with newer version.
In the log file, I've found
FATAL: no valid indexes to serve
My problem was that I tried running new version of Sphinx using index files created with an older version. It was solved by deleting all old index files and creating new indexes.
==>> close your cmd window and restart the sphinxsearch service...
I got this error suddenly, when Shpinx was working fine yesterday. Turns out the query log file was hitting 4Gb in size. I deleted it, and service started with no problems.
Make sure all the folders defined in the conf file actually exist. I was missing the LOG folder and that's why I was getting the error. Once I added the folder, the problem was solved.
