1.下载
a.官方下载链接：https://www.mongodb.com/download-center/community，我在这里选择的是这个版本：mongodb-linux-x86_64-ubuntu1604-4.0.3.tgz
b.github链接：https://github.com/mongodb/mongo，这是源码git的路径。也可以进行对源码进行编译安装。
我使用的是a方式（下载速度快些）
2.解压安装：这里只需要解压一下就OK
命令：
tar -zxvf mongodb-linux-x86_64-ubuntu1604-4.0.3.tgz修改一下文件名字：
mv mongodb-linux-x86_64-ubuntu1604-4.0.3 ./3.需要加一个配置文件。这个配置文件是第一为了指定数据存储路径，第二是为了指定logs的路径
这个是目录构造：data，conf，log 路径都是我自己手动创建的：mkdir ./log ...等等
4.在conf中添加一个mongodb.conf的一个配置文件，文件内容如下：
#mongoDB的配置文件： #端口：27017为默认端口 port = 27017 #数据存储相对路径： dbpath = data #日志 logpath = log/mongolog.log #是否以守护进程方式运行 fork = true #以追加的方式写入日志，为了防止丢失日志 logappend=true #允许远程访问 bind_ip = 0.0.0.05.启动 ：
./bin/mongod -f ./conf/mongodb.conf6.启动成功的界面
7.与项目结合。我使用的java中springboot项目。下面是我的代码：
项目结构：
8.首先先加入pom：
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-mongodb</artifactId> </dependency>9.编写配置类：（并且在启动类上面加入配置类的包扫描）
package com.socket.cn.configs; import java.util.ArrayList; import java.util.Arrays; import java.util.List; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.mongodb.config.AbstractMongoConfiguration; import org.springframework.data.mongodb.core.MongoTemplate; import com.mongodb.Mongo; import com.mongodb.MongoClient; import com.mongodb.MongoClientOptions; import com.mongodb.MongoCredential; import com.mongodb.ReadPreference; import com.mongodb.ServerAddress; @Configuration public class MongoConfig extends AbstractMongoConfiguration { private Logger logger = LoggerFactory .getLogger(MongoConfig.class); @Value("${mongodb.host}") private String mongodbHost; @Value("${mongodb.port}") private int mongodbPort; @Value("${mongodb.name}") private String mongodbName; @Value("${mongodb.user}") private String mongodbUser; @Value("${mongodb.password}") private String mongodbpwd; @Value("${mongodb.authentification}") private boolean authentification; @Bean @Override public MongoTemplate mongoTemplate() throws Exception { MongoTemplate mongoTemplate = new MongoTemplate(mongo(), mongodbName); logger.info("*******"+mongoTemplate.getDb().getName() +"基础库"); return mongoTemplate; } @Override protected String getDatabaseName() { return mongodbName; } @Override public Mongo mongo() throws Exception { MongoClient mongoClient; MongoCredential credential = MongoCredential.createMongoCRCredential(mongodbUser,mongodbName,mongodbpwd.toCharArray()); MongoClientOptions options = MongoClientOptions.builder() .connectionsPerHost(3000) .threadsAllowedToBlockForConnectionMultiplier(10) .readPreference(ReadPreference.nearest()) .build(); List<ServerAddress> addresses = new ArrayList<ServerAddress>(); String[] str = this.mongodbHost.split(","); for (String strHost : str) { ServerAddress address = new ServerAddress(strHost, mongodbPort); addresses.add(address); } if(authentification){ mongoClient = new MongoClient(addresses,Arrays.asList(credential), options); }else{ mongoClient = new MongoClient(addresses, options); } return mongoClient; } }application.properties：
server.port: 9233 mongodb.host=192.168.31.185 mongodb.port=27017 mongodb.name=book_chapter mongodb.user=admin mongodb.password= mongodb.authentification=false10.上网找了一个通用的dao，这个感觉比较好用，也可以实现快速的开发。
package com.socket.cn.dao; import org.springframework.data.mongodb.core.query.Update; public interface BaseDao<T> { boolean remove(String id); T get(String id); void insert(T t); boolean update(Update update, String id) ; } package com.socket.cn.dao.Impl; import java.lang.reflect.ParameterizedType; import org.bson.types.ObjectId; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.mongodb.core.MongoTemplate; import org.springframework.data.mongodb.core.query.Criteria; import org.springframework.data.mongodb.core.query.Query; import org.springframework.data.mongodb.core.query.Update; import org.springframework.stereotype.Repository; import com.mongodb.WriteResult; import com.socket.cn.dao.BaseDao; @Repository public class BaseDaoImp<T> implements BaseDao<T> { @Autowired private MongoTemplate mongoTemplate; private Class<T> clz; @SuppressWarnings("unchecked") public Class<T> getClz() { if (clz==null) { ParameterizedType genericSuperclass = (ParameterizedType)this.getClass().getGenericSuperclass(); clz = (Class<T>)genericSuperclass.getActualTypeArguments()[0]; } return clz; } @Override public boolean remove(String id) { Criteria criteria = Criteria.where("_id").is(new ObjectId(id)); Query query = new Query(criteria); WriteResult writeResult = mongoTemplate.remove(query, getClz()); return writeResult.getN() > 0 ? true :false; } @Override public T get(String id) { Criteria criteria = Criteria.where("_id").is(new ObjectId(id)); Query query = new Query(criteria); return mongoTemplate.findOne(query,getClz()); } @Override public void insert(T t) { mongoTemplate.insert(t); } @Override public boolean update(Update update, String id) { Criteria criteria = Criteria.where("_id").is(new ObjectId(id)); Query query = new Query(criteria); WriteResult writeResult =mongoTemplate.updateFirst(query,update,getClz()); return writeResult.getN() > 0 ? true :false; } }11.上面就是我的核心代码。下面举个栗子：
package com.socket.cn.controller; import java.util.Date; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import com.socket.cn.bean.BookChapter; import com.socket.cn.service.BookChapterService; @RestController @RequestMapping("/bookChapter") public class BookChapterController { @Autowired private BookChapterService bookChapterService; @RequestMapping("/insert") public String insert() { BookChapter bookChapter = new BookChapter(); bookChapter.setId("adasds"); bookChapter.setBookId(12321); bookChapter.setChapterContent("收到货广东省外"); bookChapter.setChapterName("广东省"); bookChapter.setCreateTime(new Date()); bookChapter.setUpdateTime(new Date()); bookChapter.setChapterLength(21); bookChapterService.insert(bookChapter); return "OK"; } } package com.socket.cn.bean; import java.io.Serializable; import java.util.Date; import org.springframework.data.annotation.Id; import org.springframework.data.mongodb.core.mapping.Document; @Document(collection = "book_chapter")//mongodb的表名 public class BookChapter implements Serializable{ private static final long serialVersionUID = -5068780066538441690L; @Id private String id; private Integer bookId; private Integer chapterId; private String chapterNumber; private String chapterName; private String chapterContent; private Integer chapterLength; private Date createTime; private Date updateTime; public BookChapter() { super(); // TODO Auto-generated constructor stub } public BookChapter(String id, Integer bookId, Integer chapterId, String chapterNumber, String chapterName, String chapterContent, Integer chapterLength, Date createTime, Date updateTime) { super(); this.id = id; this.bookId = bookId; this.chapterId = chapterId; this.chapterNumber = chapterNumber; this.chapterName = chapterName; this.chapterContent = chapterContent; this.chapterLength = chapterLength; this.createTime = createTime; this.updateTime = updateTime; } public String getId() { return id; } public void setId(String id) { this.id = id; } public Integer getBookId() { return bookId; } public void setBookId(Integer bookId) { this.bookId = bookId; } public Integer getChapterId() { return chapterId; } public void setChapterId(Integer chapterId) { this.chapterId = chapterId; } public String getChapterNumber() { return chapterNumber; } public void setChapterNumber(String chapterNumber) { this.chapterNumber = chapterNumber; } public String getChapterName() { return chapterName; } public void setChapterName(String chapterName) { this.chapterName = chapterName; } public String getChapterContent() { return chapterContent; } public void setChapterContent(String chapterContent) { this.chapterContent = chapterContent; } public Integer getChapterLength() { return chapterLength; } public void setChapterLength(Integer chapterLength) { this.chapterLength = chapterLength; } public Date getCreateTime() { return createTime; } public void setCreateTime(Date createTime) { this.createTime = createTime; } public Date getUpdateTime() { return updateTime; } public void setUpdateTime(Date updateTime) { this.updateTime = updateTime; } }12.运行结果：成功
1）.项目连接成功的日志
2).查看mongo中的数据是否保存。
