1. Download the installation package

Wget http://fastdl.mongodb.org/linux/mongodb-linux-i686-3.0.6.tgz

Extract the compressed package after the download is completed

Tar zxf mongodb-linux-i686-3.0.6.tgz

Installation preparation

Move mongodb to the / usr/local/mongodb folder

Mv mongodb-linux-i686-3.0.6 / usr/local/mongodb

Create database folders and log files

Mkdir / usr/local/mongodb/data

Touch / usr/local/mongodb/logs

Set Boot self-boot

Add the mongodb startup project to rc.local to ensure that mongodb starts when the server is powered on

Echo "/ usr/local/mongodb/bin/mongod-- dbpath=/usr/local/mongodb/data-logpath=/usr/local/mongodb/logs-logappend-- auth-port=27017" > / etc/rc.local

Start mongodb

Cd to the bin folder in the mongodb directory to start mongodb

/ / the following is the login method that requires permission, and the user needs a user name and password to connect.

/ usr/local/mongodb/bin/mongod-dbpath=/usr/local/mongodb/data-logpath=/usr/local/mongodb/logs-logappend-auth-port=27017-fork

/ / this does not require a password

/ usr/local/mongodb/bin/mongod-dbpath=/usr/local/mongodb/data-logpath=/usr/local / mongodb/logs-logappend-port=27017-fork

Start from a configuration file

Launch command: / usr/local/mongodb/bin/mongod-f mongodb.conf

[represents port number, defaults to 27017 if not specified]

Parameter interpretation:-- dbpath database path (data file)

-- logpath log file path

-- master designated as the master machine

-- slave specified as slave machine

-- source specifies the IP address of the host machine

-- pologSize specifies that the log file size does not exceed 64m. Because resync is very heavy and time-consuming, it is best to avoid resync by setting a large enough oplogSize (the default oplog size is 5% of the free disk size).

-- add at the end of the logappend log file

-- port enable port number

-- fork runs in the background

-- only specifies which database to replicate

-- slavedelay refers to the time interval detected from replication

-- whether auth needs to verify permission login (username and password)

-h [--help] show this usage information

-- version show version information

-f [--config] arg configuration file specifying additional options

-- port arg specify port number

-- bind_ip arg local ip address to bind listener-all local ips

Bound by default

-v [--verbose] be more verbose (include multiple times for more

Verbosity e.g.-vvvvv)

-- dbpath arg (= / data/db/) directory for datafiles specifies the data storage directory

-- quiet quieter output silent mode

-- logpath arg file to send all output to instead of stdout specifies the log storage directory

-- logappend appnd to logpath instead of over-writing specifies whether the log is written to the log file as an append or overwrite

-- fork fork server process runs as a child process

Cpu periodically show cpu and iowait utilization periodically displays the use of cpu and io

-- noauth run without security runs in authentication-free mode

-- auth run with security authentication mode operation

-- objcheck inspect client data for validity on receipt checks the validity of client input data

-- quota enable db quota management starts database quota management

-- quotaFiles arg number of files allower per db, requires-- quota specifies the number of files allowed per database

-- appsrvpath arg root directory for the babble app server

-- nocursors diagnostic/debugging option debug diagnostic option

-- nohints ignore query hints ignores query hit rate

-- nohttpinterface disable httpinterface shuts down the http interface. Default is 28017.

-- noscripting disable scripting engine shuts down the script engine

-- noprealloc disable data file preallocation turns off database file size pre-allocation

-smallfiles use a smaller default file size uses a smaller default file size

-- nssize arg (= 16) .ns file size (in MB) for new databases default size of the new database ns file

-- the mode provided by diaglog arg 0=off 1-write-2-R 3=both 7=W+some reads is read-only, write-only, or read-write, or mainly write + partial read mode.

-- sysinfo print some diagnostic system information print system diagnostic information

-- upgrade upgrade db if needed updates the database if necessary

-- repair run repair on all dbs repairs all databases

-- notablescan do not allow table scans does not run table scan

-- syncdelay arg (= 60) seconds between disk syncs (0 for never) the time for the system to synchronously refresh the disk. Default is 60s.

Replication options:

-- master master mode master replication mode

-- slave slave mode from replication mode

-- source arg when slave: specify master as specifies the address and port of the master when it is a slave

-- only arg when slave: when specify a single database to replicate is a slave, specify a single library to be copied from the master

-- pairwith arg address of server to pairwith

-- arbiter arg address of arbiter server arbitration server, used in the master and pair

-- autoresync automatically resync if slave data is stale automatically synchronizes slave data

-- oplogSize arg size limit (in MB) for oplog specifies the size of the operation log

-- opIdMem arg size limit (in bytes) for in memory storage of op ids specifies the amount of memory to store operation logs

Sharding options:

-- configsvr declare this is a config db of a cluster specifies the configuration server in shard

-- shardsvr declare this is a shard db of a cluster specifies shard server

Enter the CLI management interface of the database

Cd to the bin folder in the mongodb directory, and execute the command. / mongo

The operation is as follows:

[root@namenode mongodb] #. / bin/mongo

MongoDB shell version: 1.8.2

Connecting to: test

Use test

Switched to db test

If the database cannot be connected, it is a problem with the mongod.lock file in the data directory. You can use the following repair command

Mongod-repair
