Note: The end of/can not be missed! #定义数据目录, log directory (create a new data directory under the MongoDB directory, store the log, create a new logs directory, and then create a new log file in the directory, for example, we named Mongodb.log) Cd/usr/local/mongodb mkdir./data mkdir./logs Touch./logs/mongodb.log #启动mongodb (boot MongoDB for the Bin folder under CD to MongoDB directory) Here is the login method that requires permission, user name and password to connect /usr/local/mongodb/bin/mongod--dbpath=/usr/local/mongodb/data--logpath=/usr/local/mongodb/logs/mongodb.log-- Logappend--auth--port=27017--fork This one does not require a password (use this for a while!). ） /usr/local/mongodb/bin/mongod--dbpath=/usr/local/mongodb/data--logpath=/usr/local/mongodb/logs/mongodb.log-- Logappend--port=27017--fork

Parameter explanation:

--dbpath database path (data file)
--logpath log file path
--master designated as the main machine
--slave specified as from machine
--SOURCE Specifies the IP address of the primary machine
--POLOGSIZE specifies that the log file size does not exceed 64M. Because Resync is very large and time-consuming, it is best to avoid resync by setting a large enough oplogsize (the default oplog size is 5% of the size of the idle disk).
--logappend the end of the log file add
--port Enable port number
--fork running in the background
--only specify which database to copy only
--slavedelay refers to the time interval from replication detection
--auth whether to require authentication permission logins (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 addresses to bind Listener-all local IPs
Bound by default
-V [--verbose] is more verbose (include multiple
verbosity e.g.-VVVVV)
--dbpath Arg (=/data/db/) directory for datafiles specify data storage directory
--quiet Quieter output Silent mode
--logpath arg file to send all output to instead of stdout specify log storage directory
--logappend APPND to LogPath instead of over-writing Specify whether the log is written in an append or overwrite way
--fork Fork Server process to create a subprocess
--CPU periodically show CPU and iowait utilization periodic display CPU and IO usage
--noauth run without security no authentication mode
--auth run with security authentication mode
--objcheck inspect client data for validity on receipt check the validity check of clients ' input data
--quota Enable DB quota management start database quota management
--quotafiles arg number of files Allower per db, requires--quota specify how many files each database allows
--appsrvpath arg root directory for the Babble app server
--nocursors diagnostic/debugging option Debug Diagnostics options
--nohints Ignore query hints ignore hit hits
--nohttpinterface Disable HTTP Interface shutdown HTTP interface, default is 28017
--noscripting Disable scripting engine shutdown script engine
--noprealloc Disable data file preallocation shutdown database File size pre-allocation
--smallfiles use a smaller default file size with a smaller defaults
--nssize Arg (=16). ns file Size (in MB) for new databases The default size of the newly-NS files
--diaglog arg 0=off 1=w 2=r 3=both 7=w+some reads provides a way to read-only, write only, read or write, or mainly write + part of the reading mode
--sysinfo Print Some diagnostic system Information printer diagnostic information
--upgrade upgrade DB If needed update database if needed
--repair Run Repair on all DBS repairs all databases
--notablescan does not allow table scans does not run a sheet scan
--syncdelay Arg (=60) seconds between disk syncs (0 for never) system synchronized Refresh Disk Time, default 60s

Replication options:www.111cn.net
--master Master Mode primary replication mode
--slave slave mode from replication
--source Arg when slave:specify master as <server:port> specifies the address and port of the master when from
--only Arg when slave:specify a singleton to replicate specifies a single library that needs to be copied from the primary
--pairwith ARG address of the server to pair with
--arbiter arg address of arbiter server arbiter, used in main and pair
--autoresync automatically resync if slave data is stale automatic synchronization from
--oplogsize arg size limit (in MB) for OP log specifies the size of the action logs
--opidmem arg size limit (in bytes) for in memory storage of OP ids specifies the memory size of the storage action log

    Sharding options:
   --configsvr            Declare this is a config db of a cluster specify the configuration server in Shard
   --SHARDSVR&NBSP;&N bsp;          declare this is a shard db of a cluster specify Shard server
