NoSql之MongoDB入门学习

统一配置命令输入：
mongod --dbpath "F:\mongoDB\data" --logpath "F:\mongoDB\log\MongoDB.log" --install --serviceName "MongoDB"  --journal   --storageEngine=mmapv1
mongod --dbpath=E:\MongoDB\data\db  --logpath=E:\MongoDB\log\MongoDB.log --install --serviceName "MongoDB"
重新装一个MongoDB服务,注册为Windows服务， 采用连接密码认证模式
mongod --dbpath "H:\MongoDB\data" --logpath "H:\MongoDB\log\mongodb.log" --logappend --serviceName "MongoDB" --auth --install

# 启用认证
mongod --auth

CMD,将MongDB服务从windowsw服务中删除掉 
sc delete MongoDB

移除 MongoDB 服务
mongod.exe --remove
mongod --remove --serviceName "MongoDB"

启动服务
net start MongoDB

关闭MongoDB服务
net stop MongoDB

查看Windows服务
services.msc

连接MongoDB
mongo 或者mongo.exe

mongostat -u msl -p msl123 --authenticationDatabase=admin
mongostat --username=msl --password=msl123 --authenticationDatabase=admin

切换到admin数据中
use admin
切换到root管理员账户
db.auth('root','123456')

直接使用root用户登录到admin数据库
mongo admin -u root -p 123456

授予角色：db.grantRolesToUser( "userName" , [ { role: "<role>", db: "<database>" } ])  
取消角色：db.grantRolesToUser( "userName" , [ { role: "<role>", db: "<database>" } ])

db.system.users.find().pretty()
db.system.users.remove({user:"userName"})
