The file MONGO (Customer Service command)/mongod (MONGO boot command) CP to/usr/bin (the two commands become the global command)

[email protected] bin]# CP mongod/usr/bin/

[email protected] bin]# CP mongo/usr/bin/

To create a MONGO configuration file:

[Email protected] bin]# touch/etc/mongodb.conf

Configure the parameters in the file.

# config file stored in/etc/mongod.conf

#------------------------------is the content---------------------------------------

# mongo.conf

# Database File Save location

Dbpath=/usr/local/mongodb/data

# Where to save log files

Logpath=/usr/local/mongodb/logs

# logs are recorded in a way that logs are saved as added

Logappend

# requires authentication

Auth

# Run Port

port=27017

# Run in the background

Fork

# PID File path

Pidfilepath=/usr/local/mongodb/mongodb.pid

To start the MongoDB service:

[Email protected] bin]# Mongod--config=/etc/mongodb.conf

About-to-fork child process, waiting until server was ready for connections.

Forked process:30913

All output going to:/usr/local/mongodb/logs

Child process started successfully, parent exiting

To see if the service started successfully:

[Email protected] bin]# NETSTAT-LANP | grep "27017"

UNIX 2 [ACC] STREAM LISTENING 211915 30932/mongod/tmp/mongodb-27017.sock

To close the MongoDB service:

[Email protected] bin]# Mongod--dbpath=/usr/local/mongodb/data--shutdown

Killing process with pid:30913

Configure the MongoDB service to boot: add Mongod--config=/etc/mongodb.conf to/etc/rc.local

[Email protected] bin]# vi/etc/rc.local

#!/bin/sh

#

# This script is executed *after* all and the other init scripts.

# can put your own initialization stuff in here if you don ' t

# want to does the full Sys V style init stuff.

Mongod--config=/etc/mongodb.conf

=====================================

An individual's understanding of some of the important parameters:

--dbpath: Data storage directory, MongoDB boot must have parameters.

–logpath: Log storage file, MongoDB boot if not with this parameter.

--logappend: The log is written to the log file in append mode.

--auth: Users who log in to MONGO must authenticate (provide password and account number), empty account can login but do not have permission to operate DB,

If this parameter is not specified at startup, then the user logged in to MONGO has all the permissions (unsafe),

The user permissions in the Admin schema are the largest and can be queried for information in any other schema, and users in other schemas can only view information in their own schemas.

–-port: Specify port

--shutdown: Close MONGO Service

--fork: Run in the background, this parameter must be used with--logpath.
