1. Prepare the environment:
mkdir / home / mongodb # Create a directory to store program MongoDB
mkdir / data / mongodata -p # Create a data storage directory
mkdir / data / log / mongolog -p # create a log storage directory
2, downloads:
curl -O https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.2.1.tgz
3, mounting:
tar xf mongodb-linux-x86_64-3.2.1.tgz
cd mongodb-linux-x86_64-3.2.1
cp -r * / home / mongodb
In order to facilitate the command starts, you need to edit global variables PATH
vim /etc/profile.d/mongo.sh
export PATH = $ PATH: / home / mongodb / bin
source /etc/profile.d/mongo.sh
4, start the service
First check mongod help information
[Root @ test ~] # mongod --help
Options:
General options:
-h [--help] show this usage information
--version show version information
-f [--config] arg configuration file specifying
additional options
-v [--verbose] [= arg (= v)] be more verbose (include multiple times
for more verbosity e.g. -vvvvv)
--quiet quieter output
--port arg # mongodb services specified port number, default is: 27017
--bind_ip arg # on a multi-card machines where a designated mongodb service binding on ip
--ipv6 enable IPv6 support (disabled by
default)
--maxConns arg # Specify the maximum number of client connections
--logpath arg # specify the log file path must be a file instead of a directory
--syslog log to system's syslog facility instead
of file or stdout
--syslogFacility arg syslog facility used for mongodb syslog
message
--logappend # to print the log to additional --logpath parameter specifies the log file
--logRotate arg set the log rotation behavior
(Rename | reopen)
--timeStampFormat arg Desired format for timestamps in log
messages. One of ctime, iso8601-utc or
iso8601-local
--pidfilepath arg full path to pidfile (if not set, no
pidfile is created)
--keyFile arg private key for cluster authentication
--setParameter arg Set a configurable parameter
--httpinterface enable http interface
--clusterAuthMode arg Authentication mode used for cluster
authentication. Alternatives are
(KeyFile | sendKeyFile | sendX509 | x509)
--nounixsocket disable listening on unix sockets
--unixSocketPrefix arg alternative directory for UNIX domain
sockets (defaults to / tmp)
--filePermissions arg permissions to set on UNIX domain
socket file - 0700 by default
--fork # run as a daemon process in the form of services
--auth run with security
--noauth run without security
--jsonp allow JSONP access via http (has
security implications)
--rest turn on simple rest api
--slowms arg (= 100) value of slow for profile and console
log
--profile arg 0 = off 1 = slow, 2 = all
--cpu periodically show cpu and iowait
utilization
--sysinfo print some diagnostic system
information
--noIndexBuildRetry do not retry any index builds that were
interrupted by shutdown
--noscripting disable scripting engine
--notablescan do not allow table scans
--shutdown kill a running server (for init
scripts)
Replication options:
--oplogSize arg size to use (in MB) for replication op
log. default is 5% of disk space (i.e.
large is good)
Master / slave options (old; use replica sets instead):
--master master mode
--slave slave mode
--source arg when slave: specify master as
--only arg when slave: specify a single database
to replicate
--slavedelay arg specify delay (in seconds) to be used
when applying master ops to slave
--autoresync automatically resync if slave data is
stale
Replica set options:
--replSet arg arg is [/
>]
--replIndexPrefetch arg specify index prefetching behavior (if
secondary) [none | _id_only | all]
--enableMajorityReadConcern enables majority readConcern
Sharding options:
--configsvr declare this is a config db of a
cluster; default port 27019; default
dir / data / configdb
--configsvrMode arg Controls what config server protocol is
in use. When set to "sccc" keeps server
in legacy SyncClusterConnection mode
even when the service is running as a
replSet
--shardsvr declare this is a shard db of a
cluster; default port 27018
Storage options:
--storageEngine arg what storage engine to use - defaults
to wiredTiger if no data files present
--dbpath arg # specify the data directory path
--directoryperdb each database will be stored in a
separate directory
--noprealloc disable data file preallocation - will
often hurt performance
--nssize arg (= 16) .ns file size (in MB) for new databases
--quota limits each database to a certain
number of files (8 default)
--quotaFiles arg number of files allowed per db, implies
--quota
--smallfiles use a smaller default file size
--syncdelay arg (= 60) seconds between disk syncs (0 = never,
but not recommended)
--upgrade upgrade db if needed
--repair run repair on all dbs
--repairpath arg root directory for repair files -
defaults to dbpath
--journal enable journaling
--nojournal disable journaling (journaling is on by
default for 64 bit)
--journalOptions arg journal diagnostic options
--journalCommitInterval arg how often to group / batch commit (ms)
WiredTiger options:
--wiredTigerCacheSizeGB arg maximum amount of memory to allocate
for cache; defaults to 1/2 of physical
RAM
--wiredTigerStatisticsLogDelaySecs arg (= 0)
seconds to wait between each write to a
statistics file in the dbpath; 0 means
do not log statistics
--wiredTigerJournalCompressor arg (= snappy)
use a compressor for log records
[None | snappy | zlib]
--wiredTigerDirectoryForIndexes Put indexes and data in different
directories
--wiredTigerCollectionBlockCompressor arg (= snappy)
block compression algorithm for
collection data [none | snappy | zlib]
--wiredTigerIndexPrefixCompression arg (= 1)
use prefix compression on row-store
leaf pages
Start Service example:
mongod --dbpath = / data / mongodata --logpath = / data / log / mongolog / mongodb.log --logappend --fork
Check whether to activate:
netstat -tnlp | grep mongod
tcp 0 0 0.0.0.0:27017 0.0.0.0:* LISTEN 17909 / mongod
As can be seen above the port 27017 is already running
5, the test
Start mongodb the shell:
[Root @ test ~] # mongo
MongoDB shell version: 3.2.1
connecting to: test
Server has startup warnings:
