MongoDB的安装配置

1，下载：

http://www.mongodb.org/downloads

2.4.5版：http://www.mongodb.org/dr/fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.5.tgz/download

2，解压：

hadoop@hadoopmaster:~/nosql$ tar zxvf mongodb-linux-x86_64-2.4.5\ \(1\).tgz
mongodb-linux-x86_64-2.4.5/README
mongodb-linux-x86_64-2.4.5/THIRD-PARTY-NOTICES
mongodb-linux-x86_64-2.4.5/GNU-AGPL-3.0
mongodb-linux-x86_64-2.4.5/bin/mongodump
mongodb-linux-x86_64-2.4.5/bin/mongorestore
mongodb-linux-x86_64-2.4.5/bin/mongoexport
mongodb-linux-x86_64-2.4.5/bin/mongoimport
mongodb-linux-x86_64-2.4.5/bin/mongostat
mongodb-linux-x86_64-2.4.5/bin/mongotop
mongodb-linux-x86_64-2.4.5/bin/mongooplog
mongodb-linux-x86_64-2.4.5/bin/mongofiles
mongodb-linux-x86_64-2.4.5/bin/bsondump
mongodb-linux-x86_64-2.4.5/bin/mongoperf
mongodb-linux-x86_64-2.4.5/bin/mongosniff
mongodb-linux-x86_64-2.4.5/bin/mongod
mongodb-linux-x86_64-2.4.5/bin/mongos
mongodb-linux-x86_64-2.4.5/bin/mongo
hadoop@hadoopmaster:~/nosql$ ls

3，创建目录用来存放数据和log日志

hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ ls
bin  GNU-AGPL-3.0  README  THIRD-PARTY-NOTICES
hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ mkdir data
hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ mkdir log
hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$
hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ cd log/
hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5/log$ touch mongodb.log

4，启动

①：使用mongod命令建立一个mongodb数据库链接，

hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5/bin$ ./mongod -dbpath ../data/ --logpath ../log/mongodb.log
all output going to: /home/hadoop/nosql/mongodb-linux-x86_64-2.4.5/bin/../log/mongodb.log
log file [/home/hadoop/nosql/mongodb-linux-x86_64-2.4.5/bin/../log/mongodb.log] exists; copied to temporary file [/home/hadoop/nosql/mongodb-linux-x86_64-2.4.5/bin/../log/mongodb.log.2013-08-17T05-36-47]

数据库的路径为/mongodb/data，

日志路径为/mongodb/log/mongodb.log

也可以通过port指定端口号如：- -port=10000

通过接上fork参数在后台启动： --fork

5，连接：

hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5/bin$ ./mongo 127.0.0.1:10000
MongoDB shell version: 2.4.5

> show collectionsshow collections

6，配置文件的方式启动：

配置：

hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ more mongodb.conf
port=10000
dbpath=data/
logpath=log/mongodb.log
logappend=true
fork=true
hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ 

启动：

hadoop@hadoopmaster:~/nosql/mongodb-linux-x86_64-2.4.5$ ./bin/mongod  -f ./mongodb.conf
