Cp the files mongo (customer server command) / mongod (mongo startup command) to / usr/bin (these two commands become global commands)

[root@centos-1 bin] # cp mongod / usr/bin/

[root@centos-1 bin] # cp mongo / usr/bin/

Create a profile for mongo:

[root@centos-1 bin] # touch / etc/mongodb.conf

Just configure the parameters in the file.

# configuration files are stored in / etc/mongod.conf

#-- here is the content--

# mongo.conf

# location where database files are saved

Dbpath=/usr/local/mongodb/data

# location where log files are saved

Logpath=/usr/local/mongodb/logs

# Log recording method, which is saved by adding

Logappend=true

# authentication is required

Auth=true

# running port

Port=27017

# running in the background

Fork=true

# pid file path

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

Start the mongodb service:

[root@centos-1 bin] # mongod-- config=/etc/mongodb.conf

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

Forked process: 30913

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

Child process started successfully, parent exiting

Check to see if the service started successfully:

[root@centos-1 bin] # netstat-lanp | grep "27017"

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

Shut down the mongodb service:

[root@centos-1 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

[root@centos-1 bin] # vi / etc/rc.local

#! / bin/sh

#

# This script will be executed * after* all the other init scripts.

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

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

Mongod-config=/etc/mongodb.conf

Touch / var/lock/subsys/local

/ usr/local/net-snmp/sbin/snmpd-c / etc/snmpd.con

The above is the configuration and installation of mongodb

Personal understanding of some of the important parameters:

-- dbpath: data storage directory, which is a required parameter for mongodb startup.

-logpath: log stores files, if mongodb starts without this parameter.

-- logappend: the log is written to the log file as an append.

-- auth: users who log in to mongo must verify their identity (provide password and account number). Empty accounts can log in but do not have permission to operate DB.

If this parameter is not specified at startup, the user who logs in to mongo has all permissions (not secure)

Users in admin architecture have the most privileges and can query information in any other schema, while users in other schemas can only view information in their own schemas.

-- port: designated port

-- shutdown: shut down the mongo service

-- fork: runs in the background. This parameter must be used with-- logpath.
