1. Download the installation package
wget http://fastdl.mongodb.org/linux/mongodb-linux-i686-1.8.2.tgz
After the download is complete, unzip the compressed package
tar zxf mongodb-linux-i686-1.8.2.tgz
2. Installation preparation
Move mongodb to /usr/local/server/mongdb folder
mv mongodb-linux-i686-1.8.2 /usr/local/mongodb
Create database folders and log files
mkdir /usr/local/mongodb/data touch /usr/local/mongodb/logs
3. Set the boot to start automatically
Append the mongodb startup item 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
4. Start mongodb
cd to the bin folder in the mongodb directory to start mongodb
//The following is a login method that requires permissions, user connection requires a user name and password
/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
5. Parameter explanation: --dbpath database path (data file)
--logpath log file path
--master specifies the master machine
--slave specified as slave machine
--source specifies the IP address of the host machine
--pologSize specifies that the log file size should not exceed 64M. Because resync is very intensive 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).
--logappend append at the end of the log file
--port enable port number
--fork run in the background
--only specifies which database to copy only
--slavedelay refers to the time interval for slave replication detection
--auth Whether to require authentication permissions to log in (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 Quiet 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 by appending or overwriting
--fork fork server process run as a child process
--cpu periodically show cpu and iowait utilization Periodically display the usage of cpu and io
--noauth run without security run in no authentication mode
--auth run with security authentication mode operation
--objcheck inspect client data for validity on receipt
--quota enable db quota management Start 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 options
--nohints ignore query hints ignore query hit rate
--nohttpinterface disable http interface disable http interface, default is 28017
--noscripting disable scripting engine disable scripting engine
--noprealloc disable data file preallocation disable database file size preallocation
--smallfiles use a smaller default file size
--nssize arg (=16) .ns file size (in MB) for new databases Default size of new database ns file
--diaglog arg 0=off 1=W 2=R 3=both 7=W+some reads The method provided is read-only, write-only, or read-write, or the main write + partial read mode
--sysinfo print some diagnostic system information Print system diagnostic information
--upgrade upgrade db if needed update database if needed
--repair run repair on all dbs
--notablescan do not allow table scans do not run table scans
--syncdelay arg (=60) seconds between disk syncs (0 for never) The time for the system to synchronously refresh the disk, the default is 60s
Replication options:
--master master mode master replication mode
--slave slave mode slave replication mode
--source arg when slave: specify master as <server:port> When slave, specify the address and port of the master
--only arg when slave: specify a single database to replicate
--pairwith arg address of server to pair with
--arbiter arg address of arbiter server Arbiter server, used in master master and pair
--autoresync automatically resync if slave data is stale
--oplogSize arg size limit (in MB) for op log Specifies the size of the oplog
--opIdMem arg size limit (in bytes) for in memory storage of op ids specifies the memory size for storing operation logs
Sharding options:
--configsvr declare this is a config db of a cluster Specifies the config server in the shard
--shardsvr declare this is a shard db of a cluster Specify the shard server
6. Enter the CLI management interface of the database
cd to the bin folder in the mongodb directory and execute the command ./mongo
Run 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
