mongodb基本操作

1. 创建用户

// 管理员用户 db:admin
db.createUser({ user: 'admin', pwd: '123456', roles: [ { role: "userAdminAnyDatabase", db: "admin" } ] });

//应用数据库用户 db:privatenodes
db.createUser({user: "zxl",pwd: "123456",roles: [ { role: "readWrite", db: "privatenodes" } ]});

2. 创建集合

use privatenodes;
db.createCollection("networks");

3. 创建索引

use privatenodes;

// 基础索引
db.networks.createIndex({"networkid":1});

// 唯一索引
db.networks.ensureIndex({"networkid":1, "platformcode":1,"state":1,"region":1}, {unique: true});

// 删除索引
db.networks.dropIndex({"networkid":1})

4.数据操作

// 插入数据
 db.networks.insert(
 {
    "networkId": "ddd1",
    "create": {
        "req": {
            "networkId": "ddd1",
            "platformCode": "aws"
        },
        "res": {
            "hostStatus": 1,
            "hostStatusMsg": "",
            "deployStatus": 1,
            "deployStatusMsg": "dd",
            "hosts": [{
                "wanIP": "192.168.1.173"
            }, {
                "wanIP": "192.168.1.171"
            }]
        }
    },
    "delete": {
        "req": {
            "networkId": "ddd",
            "platformCode": "aws "
        },
        "res": {
            "status": 1,
            "statusMsg": ""
        }
    }
});

// 查找数据
db.networks.find({ networkId:"ddd"})
// 删除数据
db.networks.deleteOne({ networkId:"ddd1"})
// 清空数据
db.networks.drop()
