采用官方工具导出mongo数据为json格式
文档：https://docs.mongodb.com/manual/reference/program/mongoexport/
可以远程导出，只要有host:port即可。
首先需要安装tools:
在redhat中：
文档：https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/
1、编写repo文件
Create a /etc/yum.repos.d/mongodb-org-3.2.repo file so that you can install MongoDB directly, using yum.

name=MongoDB Repository
baseurl=https:

gpgcheck=

enabled=

gpgkey=https:
//www.mongodb.org/static/pgp/server-3.2.asc

2.选择安装功能
一共有以下几种选择
| mongodb-org | A metapackage that will automatically install the four component packages listed below. |
| mongodb-org-server | Contains the mongod daemon and associated configuration and init scripts. |
| mongodb-org-mongos | Contains the mongos daemon. |
| mongodb-org-shell | Contains the mongo shell. |
| mongodb-org-tools | Contains the following MongoDB tools: mongoimport bsondump, mongodump,mongoexport, mongofiles, mongooplog, mongoperf, mongorestore, mongostat, and mongotop. |
如果全部安装：
sudo yum install -y mongodb-org
如果只安装tools
sudo yum install -y mongodb-org-tools
