第1关：数据库创建

pgrep mongo -l
mongo

use mydb
db.mydb.insert({_id:1,name:"李小红"})

第2关：创建集合

#连接数据库
pgrep mongo -l
mongo
use Testdb2
db.t_stu.insert([{"_id":1,"name" : "小明","sex":"男","hobbies":["乒乓球","羽毛球"]},{"_id":2,"name" : "小红","sex":"女","hobbies":["画画","羽唱歌"]}])

第3关：文档操作一

pgrep mongo -l
mongo
use Testdb3
document=([{_id:1,name:"张小华",sex: "男",phone: "12356986594",hobbies: ["打篮球","踢足球","唱歌"]}]);
db.stu1.insert(document)
db.stu2.insert(document)    
db.stu3.insert(document)    
db.stu2.update({phone: "12356986594"},{$set:{ phone: "18356971462"}})    
db.stu3.save({_id:1,name:"张晓晓",sex: "女",phone: "12365498704",hobbies: ["跳舞","羽毛球","唱歌"]})

第4关：文档操作二
