4, create a configuration file

Vim etc/mongod.conf

[root@localhost conf] # cat mongod.conf

# Start MongoDB as a daemon on port 8908

Port = 8908

Fork = true # daemonize it!

Journal = true #

Rest = true

Logappend = true

Auth = true

Dbpath = / mongodb/data/

Logpath = / mongodb/logs/mongod.log

Pidfilepath = / mongodb/run/mongod.pid

= =

Note: for more startup parameters, please use the following command in your mongodb home directory bin directory to view the startup parameters:

[root@localhost bin] # pwd

/ mongodb/bin

[root@localhost bin] #. / mongod-help

Allowed options:

General options:

-- shardsvr declare this is a shard db of a cluster; default port

27018

5. Create the startup service file

[root@localhost conf] # cat / etc/init.d/mongod

#! / bin/bash

# mongod-Startup script for mongod

# NOTE: if you change any OPTIONS here, you get what you pay for:

# this script assumes all options are in the config file.

BASEDIR= "/ mongodb"

CONFIGFILE= "$BASEDIR/conf/mongod.conf"

OPTIONS= "- f $CONFIGFILE"

SYSCONFIG= "/ etc/sysconfig/mongod"

6. Start the service

[root@localhost logs] # service mongod restart

Stopping mongod: [failed]

Starting mongod: about to fork child process, waiting until server is ready for connections.

Forked process: 1605

All output going to: / mongodb/logs/mongod.log

Child process started successfully, parent exiting

[OK]

[root@localhost logs] # ps-ef | grep mongod

7shell enters the service command line to view

The system uses the 270117 port number by default, so the login is not successful

[root@localhost bin] #. / mongo

MongoDB shell version: 2.4.10

Connecting to: test

Wed May 21 17:28:09.809 Error: couldn't connect to server 127.0.0.1:27017 at src/mongo/shell/mongo.js:145

Exception: connect failed

Because the port number has been changed, you need to specify the port number when using it.

[root@localhost bin] #. / mongo-port 8908

MongoDB shell version: 2.4.10

OK. The above situation is considered to be successful and the service is running normally.
