MongoDB的使用

准备机器

操作系统：centos 7
机器：115.28.240.96
端口：27017

安装

下载MongoDB（64位）

wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.4.9.tgz

安装MongoDB（安装到/usr/local/目录下）

tar –zxvf mongodb-linux-x86_64-2.4.9.tgz -C /usr/local
mv mongodb-linux-x86_64-2.4.9 mongodb
cd mongodb
mkdir db # 创建数据库文件目录
mkdir logs # 创建MongoDB日志目录
cd bin

编辑mongodb.conf

vi mongodb.conf

# mongod进程存储数据目录，此配置仅对mongod进程有效。默认值为：/data/db
dbpath=/usr/local/mongodb/db
# logpath:日志目录
logpath=/usr/local/mongodb/logs/mongodb.log
# mongod侦听端口，默认值为27017
port=27017
# 后台方式运行mongodb
fork=true
# 关闭http接口
nohttpinterface=true

重新绑定mongodb的配置文件地址和IP

/usr/local/mongodb/bin/mongod --bind_ip 115.28.240.96 -f /usr/local/mongodb/bin/mongodb.conf

加入开机启动mongodb

vi /etc/rc.d/rc.local
/usr/local/mongodb/bin/mongod --bind_ip 115.28.240.96 -f /usr/local/mongodb/bin/mongodb.conf

进入mongodb看看是否能连接

/usr/local/mongodb/bin/mongo 115.28.240.96

查看数据列表

show dbs

查看当前db版本

db.version()

客户端连接测试

使用Robomongo进行连接测试

Mongodb中都以集合为主

spring data for mongodb 简单连接mongodb

创建Maven工程

pom.xml

spring data for mongodb 实现repo接口+mongoTemplate+CRUD操作

下载spring的spring-data的子项目两个jar，分别是

spring-data-commons-1.10.0.RELEASE.jar
spring-data-mongodb-1.8.4.RELEASE.jar

<dependency>
	<groupId>org.springframework.data</groupId>
	<artifactId>spring-data-commons</artifactId>
	<version>1.10.0.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework.data</groupId>
	<artifactId>spring-data-mongodb</artifactId>
	<version>1.8.4.RELEASE</version>
</dependency>

下载mongoDb的java驱动jar包

<dependency>
	<groupId>org.mongodb</groupId>
	<artifactId>mongo-java-driver</artifactId>
	<version>3.3.0</version>
</dependency>
