mongodb命令行操作流程

登录Mongo

先进入容器内部，运行命令mongo，进入mongodb的shell

root@ubuntu-70TJA00QCN:~# docker exec -it mongo /bin/bash
root@df2e73225af9:/# ls
bin  boot  data  dev  docker-entrypoint-initdb.d  etc  home  js-yaml.js  lib  lib64  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
root@df2e73225af9:/# mongo 
MongoDB shell version v4.0.6
connecting to: mongodb://127.0.0.1:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("62306e90-5429-4f00-90c5-70e1ecb68915") }
MongoDB server version: 4.0.6

选择操作的数据库

>use dbname
switched to db dbname

这里的dbname替换成自己的数据库名称

为数据库创建用户

> db.createUser({user: "username", pwd: "password", roles: [{ role: "dbOwner", db: "dbname" }]})
Successfully added user: {
        "user" : "manage",
        "roles" : [
                {
                        "role" : "dbOwner",
                        "db" : "dbname"
                }
        ]
}

用户名密码登录

> db.auth("username", "password")
1
>

将这里的username和password替换成该数据库的用户名密码，返回1则代表登录成功。

添加索引

> db.collectionName.createIndex({"param1":1,"param2":1,"param3":1,"param4":1})
{
    "createdCollectionAutomatically" : true,
    "numIndexesBefore" : 1,
    "numIndexesAfter" : 2,
    "ok" : 1
}
> db.collectionName.getIndexes()
[
    {
        "v" : 2,
        "key" : {
            "_id" : 1
        },
        "name" : "_id_",
        "ns" : "dbname.collectionName"
    },
    {
        "v" : 2,
        "key" : {
            "param1" : 1,
            "param2" : 1,
            "param3" : 1,
            "param4" : 1
        },
        "name" : "param1_1_param2_1_param3_1_param4_1",
        "ns" : "dbname.collectionName"
    }
]
> 

db.collectionName.createIndex命令是创建索引，其中的collectionName是集合名称，param是数据中的参数，为1时创建的是正序的索引，为-1创建的是逆序的索引。db.col.getIndexes()命令是获取当前数据库的所有索引。

所有索引列表

> db.udpdata.createIndex({"dataTypeId":1,"deviceName":1,"productKey":1,"timeStamp":1})
> db.udpdata.createIndex({"dataTypeId":1,"deviceName":1,"productKey":1,"timeStamp":-1})
> db.udpdata.createIndex({"deviceName":1,"timeStamp":-1})
> db.udpdata.createIndex({"dataTypeId":1,"deviceName":1,"productKey":1,"data.status":1})
> db.udpdata.createIndex({"dataTypeId":1,"requestId":1})
> db.udpdata.createIndex({"dataTypeId":1,"periodId":1})
> db.udpdata.createIndex({"applicationId":1,"dataTypeId":1,"timeStamp":1})
> db.udpdata.createIndex({"dataTypeId":1,"timeStamp":1})

> db.udpdata.getIndexes()
