我本地的环境
MongoDB 4.0
jdk 1.7.x
安装参考主要博客
https://blog.csdn.net/wanght89/article/details/77677271#commentBox（记得安装完对解压包做个备份）
按照该网址安装过程中，遇到一些问题的解决方法：
1.
多了一个"g",应为
config_set={"_id":"mySet",members:[{_id:0,host:"127.0.0.1:27111"},{_id:1,host:"127.0.0.1:27112"},{_id:2,host:"127.0.0.1:27113"}]}
2.启动MongoDB的时候，要进入相应的bin目录
mongod -port 27111 -dbpath D:\MongoDB\matserdb -logpath D:\MongoDB\matserlog\mongod.log -replSet mySet -logappend mongod -port 27112 -dbpath D:\MongoDB\slavedb -logpath D:\MongoDB\slavelog\mongod.log -replSet mySet -logappend mongod -port 27113 -dbpath D:\MongoDB\arbiterdb -logpath D:\MongoDB\arbiterlog\mongod.log -replSet mySet -logappend
3.设置仲裁节点
rs.addArb("192.168.32.138:27017")或者
rs.add("host:port",{arbiterOnly:true})
4.默认情况下SECONDARY节点不能读写，要设置slaveOK为true才行
db.getMongo().setSlaveOk()或
rs.slaveOk()
5.停止MongoDB服务
db.shutdownServer()
7.如果某一个节点不能启动了，删除db下的所有文件以及文件夹，将备份中的data中的所有复制到刚删除的db中，重启即可成功
8.插入测试数据
db.say.insert({"text":"hello world"});
9.创建用户名、密码
mongo --port 27017 use admin db.createUser( { user: "adminUser", pwd: "adminPass", roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] } )
10.Java代码
package com.alibaba.fescar.dubbo; import java.util.ArrayList; import java.util.List; import com.mongodb.BasicDBObject; import com.mongodb.DB; import com.mongodb.DBCollection; import com.mongodb.DBObject; import com.mongodb.MongoClient; import com.mongodb.ServerAddress; public class ReplSetTest { public static void main(String[] args) { try { List<ServerAddress> addresses = new ArrayList<ServerAddress>(); ServerAddress address1 = new ServerAddress("127.0.0.1", 27111); ServerAddress address2 = new ServerAddress("127.0.0.1", 27112); ServerAddress address3 = new ServerAddress("127.0.0.1", 27113); addresses.add(address1); addresses.add(address2); addresses.add(address3); MongoClient client = new MongoClient(addresses); DB db = client.getDB( "test" ); DBCollection coll = db.getCollection("say"); BasicDBObject object = new BasicDBObject(); object.append( "name" , "user28"); DBObject dbObject = coll.findOne(object); BasicDBObject obj = new BasicDBObject(); obj.put("name", "3333"); obj.put("age", 330); obj.put("sex", 2); coll.insert(obj); System.out .println(dbObject); } catch (Exception e) { e.printStackTrace(); } } }
