[MongoDB] Installation

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

   wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.8.tgz

   Then unzip:

   tar zxvf mongodb-linux-x86_64-2.2.3.tgz

   Move directory to/usr/local/mongodb

   mv 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

   Show

   process: 18261all output going to: /usr/local/mongodb/logs/mongodb.loglog file [/usr/local/mongodb/logs/mongodb.log] exists; copied to temporary file [/usr/local/mongodb/logs/mongodb.log.2013-03-01T04-04-28]child process started successfully, parent exiting

   To set up boot from:

   echo "/usr/local/mongodb/bin/mongod --dbpath=/usr/local/mongodb/data/db --logpath=/usr/local/mongodb/logs/mongodb.log --fork" >> /etc/rc.local

   View MongoDB Logs

   tail -f /usr/local/mongodb/logs/mongodb.log

   To view or debug the operation of MongoDB.
   View MongoDB Process

   ps aux |grep mongodb

   Show

   root     18261  0.0  1.4 150392 29948 ? Sl 12:04 0:00 /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 main machine
   --slave specified as Slave machine
   --source Specify the IP address of the host 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 sufficiently large oplogsize (the default oplog size is 5% of the size of the free disk).
   --logappend log file End add
   --port Enable port numbers
   --fork running in the background
   --ONLY specifies which database to replicate only
   --slavedelay refers to the time interval from which replication is detected
   --auth If you need to verify permissions login (username and password)
