Linux端安装
我们从MonDB官网下载Linux端的安装包，建议下载4.0版本
打开虚拟机，在虚拟机上安装传输工具lrzsz,将下载好的.tgz包拖到虚拟机当中，拖到/usr/local/mongoDB目录下，
[root@server ~]# yum install -y lrzsz
[root@server ~]# cd /usr/local/
[root@server local]# mkdir mongoDB
[root@server local]# cd mongoDB/
[root@server mongoDB]# rz -E
rz waiting to receive.

-rw-r--r--. 1 root root 105017141 Apr 24 14:35 mongodb-linux-x86_64-rhel80-4.0.28.tgz 
使用tar命令进行解压缩
[root@server mongoDB]# tar -xvf mongodb-linux-x86_64-rhel80-4.0.28.tgz

[root@server bin]# useradd mongod
[root@server bin]# passwd mongod
Changing password for user mongod.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@server mongodbserver]# chown -R mongod:mongod /usr/local/mongoDB/mongodbserver添加环境变量/etc/profile
export PATH=/usr/local/mongoDB/mongodbserver/bin:$PATH进入普通用户mongod，输入mongo启动完成

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).
The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.
To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()
