smorin$ ./mongod --dbpath ../../mongodata/ --help
Allowed options:
General options:
-h [ --help ] show this usage information
--version show version information
-f [ --config ] arg configuration file specifying additional options
-v [ --verbose ] be more verbose (include multiple times for more
verbosity e.g. -vvvvv)
--quiet quieter output
--port arg specify port number
--bind_ip arg comma separated list of ip addresses to listen on -
all local ips by default
--logpath arg log file to send write to instead of stdout - has to
be a file, not directory
--logappend append to logpath instead of over-writing
--pidfilepath arg full path to pidfile (if not set, no pidfile is
created)
--keyFile arg private key for cluster authentication (only for
replica sets)
--unixSocketPrefix arg alternative directory for UNIX domain sockets
(defaults to /tmp)
--fork fork server process
--auth run with security
--cpu periodically show cpu and iowait utilization
--dbpath arg directory for datafiles
--diaglog arg 0=off 1=W 2=R 3=both 7=W+some reads
--directoryperdb each database will be stored in a separate directory
--journal enable journaling
--journalOptions arg journal diagnostic options
--ipv6 enable IPv6 support (disabled by default)
--jsonp allow JSONP access via http (has security
implications)
--maxConns arg max number of simultaneous connections
--noauth run without security
--nohttpinterface disable http interface
--noprealloc disable data file preallocation - will often hurt
performance
--noscripting disable scripting engine
--notablescan do not allow table scans
--nounixsocket disable listening on unix sockets
--nssize arg (=16) .ns file size (in MB) for new databases
--objcheck inspect client data for validity on receipt
--profile arg 0=off 1=slow, 2=all
--quota limits each database to a certain number of files (8
default)
--quotaFiles arg number of files allower per db, requires --quota
--rest turn on simple rest api
--repair run repair on all dbs
--repairpath arg root directory for repair files - defaults to dbpath
--slowms arg (=100) value of slow for profile and console log
--smallfiles use a smaller default file size
--syncdelay arg (=60) seconds between disk syncs (0=never, but not
recommended)
--sysinfo print some diagnostic system information
--upgrade upgrade db if needed
Replication options:
--fastsync indicate that this instance is starting from a dbpath
snapshot of the repl peer
--autoresync automatically resync if slave data is stale
--oplogSize arg size limit (in MB) for op log
Master/slave options:
--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
Replica set options:
--replSet arg arg is[/]
Sharding options:
--configsvr declare this is a config db of a cluster; default port
27019; default dir /data/configdb
--shardsvr declare this is a shard db of a cluster; default port
27018
--noMoveParanoia turn off paranoid saving of data for moveChunk. this
is on by default for now, but default will switch
