最近项目需要使用 MongoDB，所以不得不搭建 MongoDB 环境，此文记录搭建过程及使用过程中需要了解的问题。
Linux + Windows 混合搭建调试 MongoDB 记录
版本介绍 ：
windows ： win10 64bit
linux：ubuntu 14.0.4
nodejs：6.11.2
MongoDB： 4.0.9
MongoDB安装
MongoDB下载地址：https://www.mongodb.com/download-center/community
ubuntu安装MongoDB
1. 下载：点击上方链接选择目标
可以直接点击 DownLoad 下载，或者使用上图链接下载
解压提取
将其中内容移动到/usr/local/mongodb
2. 创建用于存储的数据库和日志目录，数据都将存于此地
该路径可配置，配置文件中要相应参数与之对应
mkdir -p /data/db # 默认数据库目录路径，应手动予以创建
mkdir -p /data/logs
3. 配置环境变量
vi ~/.bashrc在最后一行插入
export PATH=/usr/local/mongodb/bin:$PATH
4. 运行MongoDB 服务
root@qizhuang-virtual-machine:/# mongod运行结果：

如果你需要进入MongoDB后台管理，你需要先打开mongodb装目录的下的bin目录，然后执行mongo命令文件。
MongoDB Shell是MongoDB自带的交互式Javascript shell,用来对MongoDB进行操作和管理的交互式环境。

mongod 配置文件
注意：1. ip 2. auth

mongodb 角色预授权
注意：1. root角色 2. 在某个库下创建的用户隶属于这个库

Java mongodb
使用MongoCollection，BasicDBObject 条件查询
//链接数据库
MongoClient mongoClient = new MongoClient( "172.26.xxx.xxx" , 27017 );
MongoDatabase mongoDatabase =mongoClient.getDatabase("xxxx");
MongoCollection<Document> collection = mongoDatabase.getCollection("test_logs");
//加入查询条件
BasicDBObject query = new BasicDBObject();
//时间区间查询 记住如果想根据这种形式进行时间的区间查询 ，存储的时候 记得把字段存成字符串，就按yyyy-MM-dd HH:mm:ss 格式来
query.put("times", new BasicDBObject("$gte", "2018-06-02 12:20:00").append("$lte","2018-07-04 10:02:46"));
//模糊查询
Pattern pattern = Pattern.compile("^.*王.*$", Pattern.CASE_INSENSITIVE);
query.put("userName", pattern);
//精确查询
query.put("id", "11");
//skip 是分页查询，从第0条开始查10条数据。 Sorts是排序用的。有descending 和ascending
MongoCursor<Document> cursor = collection.find(query).sort(Sorts.orderBy(Sorts.descending("times"))).skip(0).limit(10).iterator();//
int unm=0;
try {
while (cursor.hasNext()) {
UserBehaviorLogs userBehaviorLogs = new UserBehaviorLogs();
//查询出的结果转换成jsonObject,然后进行封装或者直接返回给前端处理。我这是封装成对象了
JSONObject jsonObject = JSONObject.parseObject( cursor.next().toJson().toString());
userBehaviorLogs.setId(jsonObject.getString("id"));//id
userBehaviorLogs.setUserId(jsonObject.getString("userId"));//用户id
userBehaviorLogs.setUserName(jsonObject.getString("userName"));//用户名称
userBehaviorLogs.setParams(jsonObject.getString("params"));//参数
userBehaviorLogs.setException(jsonObject.getString("Exception"));//异常信息
userBehaviorLogs.setTimes(jsonObject.getString("times")+"");//创建时间
unm++;
System.out.println(unm+"="+userBehaviorLogs.getTimes()+"==="+userBehaviorLogs.getId());
}
} catch (Exception e) {
e.printStackTrace();
} finally {
cursor.close();
}
