序言

Mongodb 教程其实早在一年前就一直想写一写，因为工作比较忙，自己也没有真的大量用于真实项目里的实践，一直耽搁了

简介

MongoDB是一个基于分布式文件存储的数据库.

官网

单机安装

三种安装支持

1. window安装可参考

mongodb单机 在window下安装测试

2. 类unix系下安装

wget https://fastdl.mongodb.org/osx/mongodb-osx-ssl-x86_64-4.0.6.tgztar zxvf mongodb-osx-ssl-x86_64-4.0.6.tgzcd mongodb-osx-ssl-x86_64-4.0.6/binmongod --config /xx/xx.config --fork

3. docker安装

# -p local_port:docker_portdocker pull mongo:4.1.5docker run -d --name mongodb-4.1.5 -e MONGO_INITDB_ROOT_USERNAME=root -e MONGO_INITDB_ROOT_PASSWORD=123456 -v /data/mongodb/docker/4.1.5:/mongodb -v /data/mongodb/docker/4.1.5/conf.d:/etc/mongo -p 27077:27017 mongo:4.1.5 --config /etc/mongo/mongod.conf --auth

连接测试

mongo --host 127.0.0.1 --port 27077> db.auth("root", "123456")1> show dbs;admin   0.000GBconfig  0.000GBlocal   0.000GB

创建新数据和账号

> use demo;switched to db demo> db.createUser({... user : "demo",... pwd: "123456",... roles : [... {... "role" : "dbAdmin",... "db" : "demo"... },... {... "role" : "dbOwner",... "db" : "demo"... }... ],... "mechanisms" : [... "SCRAM-SHA-1",... "SCRAM-SHA-256"... ]... });Successfully added user: {    "user" : "demo",    "roles" : [        {            "role" : "dbAdmin",            "db" : "demo"        },        {            "role" : "dbOwner",            "db" : "demo"        }    ],    "mechanisms" : [        "SCRAM-SHA-1",        "SCRAM-SHA-256"    ]}> exit;

测试插入和查询
