(1) Go to MongoDB Download Center : http://www.mongodb.org/downloadsWe recommend using these binary distributions (binary version is officially recommended) !) (2) according to their actual system environment , download the required files, mine is the Linux 64-bit.

wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.2.3.tgz

then unzip :

Tar zxvf mongodb-linux-x86_64-2.2.3.tgz

Move directory to /usr/local/mongodb

Mv-f mongodb-linux-x86_64-2.2.3/*/usr/local/mongodb

Go to the MongoDB directory

Cd/usr/local/mongodb

New Custom Data Catalog

Mkdir-p./data/db/

New log Directory

mkdir logs

Next Run mode start MongoDB

/usr/local/mongodb/bin/mongod--dbpath=/usr/local/mongodb/data/db--logpath=/usr/local/mongodb/logs/mongodb.log- -fork

parameter explanation :--dbpath database path (data file)--logpath log file path--master designated as the primary machine--slave designated as the IP address of the host machine--source Specifies that the log file size does not exceed 64M. Because the resync is extremely operational 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 log file at the end of the Add--port enable port number--fork run in the background--only specify which database to replicate only--slavedelay refers to the time interval from replication detection--auth Whether authentication permission is required to log on (user name and password)
