comparison with traditional databases(NoSQL abandons the function on the left.) But the right side brings advantages)
Why use MongoDB1. No data structure limit 1. Without the concept of a table structure, a daily record can have a completely different structure 2. Easy and quick business development 3. SQL database needs to implement the definition table structure and then use 2. Full index support 1. Redis's Key-value 2. Single index of HBase, headset index needs to be implemented by itself
3. Convenient redundancy and expansion 1. Replication sets guarantee data security 2. Shard Scale Data size

build a simple MongoDB server1. First create a mongodb_simple directory and go to directory 2. Create folder: Data, which is used to store the database file 3. Create folder: Log, which is used to store the database 4. Create folder: Bin, the executable file used to store the database 5. Create folder: conf, the configuration file used to store the database
[[email protected]test]# mkdir Mongodb_simple
[[email protected]test]# CD mongodb_simple/
[[email protected]mongodb_simple]# mkdir Data
[[email protected]mongodb_simple]# mkdir Log
[[email protected]mongodb_simple]# mkdir conf
[[email protected]mongodb_simple]# MkDir Bin
Copy the compiled MONGO to the bin # Cp/home/hadoop/desktop/mongodb-linux-i686-2.6.10/bin/mongod bin/
Enter conf, edit startup file [[email protected]mongodb_simple]# CD conf
[[email protected]conf]# Vim Mongod.confpath = 12345dbpath = Datalogpath = Log/mongod.logfork = True
Save exit. Description: Port listening ports DBPath data store directory logpath log file path (to indicate the actual file) fork means start a background process
start,-F sets the configuration file to be executed at startup./bin/mongod-f conf/mongod.conf (failure using the following method)
It's not going to start, so you can start with this./bin/mongod-dbpath=/test/mongodb_simple/data/-logpath=/test/mongodb_simple/log/mongod.log-port= 12345--fork
successfully started.
Enter the data directory to see the initialized directories and files
Log information can also be seen under log tail.
Connect to a MongoDB serverconnection (for easy use, copy the MONGO to the previous bin)[[email protected]mongodb_simple]# Cp/home/hadoop/desktop/mongodb-linux-i686-3.0.3/bin/mongo./bin
Connection[email protected]momgodb_simple]#./bin/mongo 127.0.0.1:12345/test
See the haircut to show success. But there's a warning.
Close MongoDB Service > Db.shutdownserver () (You can also use kill-15 do not use -9) Ctrl + C to exit. View the next log log
you can see that you have exited.
