Shulou(Shulou.com)06/01 Report--

Today, according to the download wizard of the MongoDB official website to install MongoDB, the service of starting MongoDB was found to be unable to start.

After a whole night of hard work, I finally got it. I hope I can help comrades who have the same difficulties.

First of all, Google and du Niang have searched countless articles and made numerous attempts, all of which have failed.

Try 1: some people say it's because of SElinux, but they still can't start it after shutting down SElinux.

Try 2: modify var/lib/mongo permissions, increase write permissions, invalid.

Try 3: create a new Data directory, and then use mongod-- dbpath to configure the Data directory, which still doesn't work.

Try 4: modify / etc/init.d/mongod file permissions, still invalid.

Finally, I read the mongo.conf documentation in the / etc directory and learned something. And found an article on Baidu:

The article says:

Delete the file:

Rm / data/mongodb/mongo.lock-- linux

Del / data/mongodb/mongo.lock-- windows

Then execute:

. / mongod-- repair

So I found the mongod.lock file under / var/lib and deleted it.

Finally, in the execution of mongod-repair

And then start the mongod service successfully!

Hope to help comrades who install according to the official website and then can't start the service.
