V. Restart CentOS

Shutdown-r now

Six, into the MONGO shell
Under the Bin directory

./mongo

The following error occurred:

MongoDB Shell version:3.0.2connecting to:test2015-05-06t13:38:16.832+0800 W NETWORK Failed to connect to 127.0.0.1:2701 7, reason:errno:111 Connection refused2015-05-06t13:38:16.834+0800 E QUERY error:couldn ' t connect to server 127.0.0.1 : 27017 (127.0.0.1), connection attempt failed at connect (src/mongo/shell/mongo.js:179:14) at (Connect): 1:6 at src/m Ongo/shell/mongo.js:179exception:connect failed

Vii. Solutions:

Rm-f/apps/mongodb/data/db/mongod.lock

Viii. restart./mongo but I failed again.
Nine, (small white) I think maybe the mongod service didn't start, and then I tried.

Service Mongod Start

As a result you may have guessed it:
Mongod:unrecognized Service
From the Internet to find a bit, there is a permission problem, that is, install what is root, but Mongod is the user MongoDB (later I refer to another document to fix)
Ten, I think, I will be in the MongoDB installation directory under the bin execution

./mongod

Then I open another terminal, re-enter/apps/mongodb/mongo (extracted filename)/bin under the execution

./mongo

11, now it's done.

MongoDB Shell version:3.0.2connecting to:testwelcome to the MongoDB shell.
