mongodb数据库基本操作

mongodb shell

添加用户赋权限

use socketProject
db.createUser({user:'dev',pwd:"1111111",roles:[{role:"readWrite",db:"socketProject"}]})
db.createUser({user: "admin",pwd: "1111",roles: [ { role: "userAdminAnyDatabase", db: "admin" }, "readWriteAnyDatabase" ]})
db.createUser({user: "root",pwd: "1111",roles: [ { role: "root", db: "admin" } ]})

认证

use socketProject
db.auth('dev','1111111')

查询

use socketProject
db.notify.find()
db.notify.find({ip:'1.1.1.1'})

删除

use socketProject
db.notify.deleteOne({ip:'1.1.1.1'})
db.notify.deleteMany({ip:'1.1.1.1'})
db.notify.drop()

导出

/usr/local/mongodb/bin/mongoexport -h 127.0.0.1 -u dev -p '1111' -d socketProject -c notify -o /tmp/notify.json

导入

mongoimport -h 127.0.0.1 -u dev -p '1111' -d socketProject -c notify --file notify.json 

备份

从原数据库中备份：

/usr/local/mongodb/bin/mongodump -h 127.0.0.1 -u wiki -p '22222' -d wiki -o /tmp/wiki

恢复

/usr/local/mongodb/bin/mongorestore -h 127.0.0.1 -u wiki -p '22222' -d wiki --drop  /tmp/wiki/wiki
