mongodb 192.168.5.136:58013 shard4节点2
mongodb 192.168.5.136:58015 shard4节点3
mongodb 192.168.5.136:58017 shard4仲裁节点

3.配置节点配置

建立17011配置节点的配置信息,vi config-17011.conf

dbpath=config/config1
# 日志文件位置
logpath=config/logs/config1.log
# 以追加方式写入日志
logappend=true
# 是否以守护进程方式运行
fork = true
bind_ip=0.0.0.0
port = 17011
# 表示是一个配置服务器
configsvr=true
# 配置服务器副本集名称
replSet=configsvr
#auth=true
#keyFile=data/mongodb/testKeyFile.file

以上为17011端口的配置节点配置,17013,17015节点的以此相同
注意:需提前建立dbpath和logpath指定的文件夹,否则启动报错
建立3个节点后进行启动,使用mongodb下bin目录里面的命令启动,例如:./bin/mongod -f config/config-17011.conf,依次启动17011,17013,17015

随意进入其中一个节点,./bin/mongo --port 17011,将3个配置节点添加进集群:

use admin

var cfg ={"_id":"configsvr", "members":[ 
{"_id":1,"host":"192.168.5.136:17011"}, 
{"_id":2,"host":"192.168.5.136:17013"},
 {"_id":3,"host":"192.168.5.136:17015"}] 
 };
 
rs.initiate(cfg)

配置节点完成

4.配置数据节点分片shard1

建立节点37011配置文件,vi shard1-37011.conf

dbpath=shard/shard1/shard1-37011
bind_ip=0.0.0.0
port=37011
fork=true
logpath=shard/shard1/logs/shard1-37011.log
replSet=shard1
shardsvr=true
#auth=true
#keyFile=data/mongodb/testKeyFile.file

依次建立37013,37015,37017节点的配置文件
启动节点:

./bin/mongod -f shard/shard1/shard1-37011.conf
./bin/mongod -f shard/shard1/shard1-37013.conf
./bin/mongod -f shard/shard1/shard1-37015.conf
./bin/mongod -f shard/shard1/shard1-37017.conf

进入其中一个节点,将节点加入集群:

var cfg ={"_id":"lagouCluster", "protocolVersion" : 1, "members":[ 
   {"_id":1,"host":"192.168.5.136:37011"},
   {"_id":2,"host":"192.168.5.136:37013"} ,
   {"_id":2,"host":"192.168.5.136:37015"} ,
   {"_id":2,"host":"192.168.5.136:37013","arbiterOnly":true} 
 ] }
 rs.initiate(cfg) 
 rs.status()

“arbiterOnly”:true标识为仲裁节点
按照上面步骤,建立shard2,shard3,shard4分片集群

5.建立路由节点

为27017路由节点建立配置文件,vi route-27017.conf

port=27017
bind_ip=0.0.0.0
fork=true
logpath=route/logs/route.log
configdb=configsvr/192.168.5.136:17011,192.168.5.136:17013,192.168.5.136:17015
#keyFile=data/mongodb/testKeyFile.file

启动路由节点: ./bin/mongos -f route/route-27017.conf
进入路由节点,将数据分片添加进去:

sh.status() 
sh.addShard("shard1/192.168.5.136:37011,192.168.5.136:37013,192.168.5.136: 37015,192.168.5.136: 37017"); 
sh.addShard("shard2/192.168.5.136:47011,192.168.5.136:47013,192.168.5.136: 47015,192.168.5.136: 47017"); 
sh.addShard("shard3/192.168.5.136:57011,192.168.5.136:57013,192.168.5.136: 57015,192.168.5.136: 57017"); 
sh.addShard("shard1/192.168.5.136:58011,192.168.5.136:58013,192.168.5.136: 58015,192.168.5.136: 58017"); 
sh.status()

开启分片:

为数据库开启分片功能 
sh.enableSharding("lagou_resume") 
为指定集合开启分片功能
 sh.shardCollection("lagou_resume.lagou_resume_datas",{"name":“hashd”})

6.测试分片功能

往route路由节点里插入数据:
在这里插入图片描述

7.开启权限认证

mongodb默认没有用户,所以需要先建立一个root用户,后续才可以进行用户权限的更改

use admin 
db.createUser( {  user:"root",  pwd:"123456", roles:[{role:"root",db:"admin"}]  })

生成密钥文件,放在mongodb目录下的data/mongodb,没有需要新建

openssl rand -base64 756 > data/mongodb/testKeyFile.file 
#修改执行权限
chmod 600 data/mongodb/keyfile/testKeyFile.file

需要在config节点和数据分片节点增加配置

auth=true
keyFile=data/mongodb/testKeyFile.file

在route节点配置中增加配置

keyFile=data/mongodb/testKeyFile.file

重启所有的mongodb实例,要按顺序启动;可使用脚本启动

./bin/mongod -f config/config-17011.conf
./bin/mongod -f config/config-17013.conf
./bin/mongod -f config/config-17015.conf
./bin/mongod -f shard/shard1/shard1-37011.conf
./bin/mongod -f shard/shard1/shard1-37013.conf
./bin/mongod -f shard/shard1/shard1-37015.conf
./bin/mongod -f shard/shard1/shard1-37017.conf

./bin/mongod -f shard/shard2/shard2-47011.conf
./bin/mongod -f shard/shard2/shard2-47013.conf
./bin/mongod -f shard/shard2/shard2-47015.conf
./bin/mongod -f shard/shard2/shard2-47017.conf

./bin/mongod -f shard/shard3/shard3-57011.conf
./bin/mongod -f shard/shard3/shard3-57013.conf
./bin/mongod -f shard/shard3/shard3-57015.conf
./bin/mongod -f shard/shard3/shard3-57017.conf

./bin/mongod -f shard/shard4/shard4-58011.conf
./bin/mongod -f shard/shard4/shard4-58013.conf
./bin/mongod -f shard/shard4/shard4-58015.conf
./bin/mongod -f shard/shard4/shard4-58017.conf

./bin/mongos -f route/route-27017.conf

认证用户,要进入对应数据库;认证完之后才可以操作

use admin
db.auth("root","123456")

8.集成springboot

添加依赖


       
           org.springframework.boot
           spring-boot-starter-data-mongodb
           2.2.2.RELEASE
       
   

创建实体

@Document("lg_resume_datas")
public class Resume {....}

创建dao接口和实现类

@Service("resumeDao")
public class ResumeDAOImpl implements ResumeDAO {
    @Autowired
    private MongoTemplate mongoTemplate;
    @Override
    public void insertResume(Resume resume) {
        //mongoTemplate.insert(resume);
        mongoTemplate.insert(resume,"lg_resume_datas");
    }

    @Override
    public Resume findByName(String name) {
        Query query = new Query();
        query.addCriteria(Criteria.where("name").is(name));
        List datas = mongoTemplate.find(query,Resume.class,"lg_resume_datas");
        return  datas.isEmpty()?null:datas.get(0);
    }

    @Override
    public List findList(String name) {
        Query query = new Query();
        query.addCriteria(Criteria.where("name").is(name));
        List datas = mongoTemplate.find(query,Resume.class,"lg_resume_datas");
        return  datas;
    }

    @Override
    public List findListByNameAndExpectSalary(String name, double expectSalary) {
        Query query = new Query();
        //query.addCriteria(Criteria.where("name").is(name).andOperator(Criteria.where("expectSalary").is(expectSalary)));
        query.addCriteria(Criteria.where("name").is(name).andOperator(Criteria.where("expectSalary").is(expectSalary)));
        return  mongoTemplate.find(query,Resume.class,"lg_resume_datas");
    }
}

测试用例

@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        ApplicationContext applicationContext  = SpringApplication.run(DemoApplication.class,args);
        ResumeDAO resumeDao = applicationContext.getBean("resumeDao",ResumeDAO.class);

        testInsert(resumeDao);

        testQuery(resumeDao);
    }

    private static void testQuery(ResumeDAO resumeDao) {
        Resume  resume2  =resumeDao.findByName("lisi22");
        System.out.println(resume2);
    }

    private static void testInsert(ResumeDAO resumeDao) {
        Resume resume  = new Resume();
        resume.setName("赵六");
        resume.setCity("北京");
        Date date = null;
        String  dateStr = "yyyy-MM-dd hh:mm:ss";
        SimpleDateFormat simpleDateFormat  = new SimpleDateFormat(dateStr);
        try {
            date = simpleDateFormat.parse("2003-11-02 11:13:14");
        } catch (ParseException e) {
            e.printStackTrace();
        }
        resume.setBirthday(date);
        resume.setExpectSalary(28000);
        resumeDao.insertResume(resume);
        System.out.println("resume="+resume);
    }
}
