MongoDB Finishing Notes installation and configuration

1. Download the website

Address: Http://www.mongodb.org/downloads

MONGODB-LINUX-X86_64-2.4.9.TGZ (64 latest version so far)

2. Decompression

Switch to the download directory, command line input: Tar zxf mongodb-linux-x86_64-2.4.9.tgz

3. Create database folders and log files

Command Line Input:

Mkdir/usr/local/mongodb/data

Touch/usr/local/mongodb/logs

The above two lines of command represent, all MONGODB related operations of the database files, are saved in/usr/local/mongodb/data this directory, the resulting log is saved in/usr/local/mongodb/logs this

In the file. Attention! Logs is a file, not a directory.

4. Start MongoDB Service

Standard boot form, start with file, switch to mongodb installation directory, command line input:

Bin/mongod--dbpath=/usr/local/server/mongodb/data--logpath=/usr/local/server/mongodb/logs

Take a closer look at the command line, it's easy to see why you just created the database folder and log file!

5. Set Boot start

Command line input (/home/data/mongodb2.4.9/for my MongoDB installation path):

echo "/home/data/mongodb2.4.9/bin/mongod--dbpath=/usr/local/server/mongodb/data–logpath=/usr/local/server/ mongodb/logs–logappend–port=27017 ">>/etc/rc.local

In fact, we can also summarize ourselves, such as these our own installation of tools, such as mongodb,logstash,redis,es and so on boot settings, all the same, uniform format:

Command line input: echo "Start command" >>/etc/rc.local

So the configuration for boot start is in the Rc.local file!

6, if the database appears as not connected, it is a data directory under the Mongod.lock file problem, you can use the following repair command, Mongod--repair

7, give everyone a detailed command line, parameter interpretation

--dbpath database path (data file)--logpath log file path--master designated as the primary machine--slave specified as the IP address of the host machine--source       OLOGSIZE 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 number--fork run in background

--ONLY specifies which database to replicate only

--slavedelay refers to the time interval from replication detection--auth whether authentication rights are required to log on (user name and password)
8. Operation MongoDB
Switch to the MongoDB installation directory and enter the command line:
Bin/mongo
As appears
MongoDB Shell version:2.4.9 connecting to:test (default connected database test)
Congratulations, you can start working on MongoDB!
