部署mongodb服务

（1）官网下载mongodb-linux-aarch64-ubuntu1804-4.2.25.tgz压缩包
（2）上传至服务器，解压
（3）设置环境变量

vi /etc/profile
export PATH=/data/software/mongodb/mongodb-linux-aarch64-ubuntu1804-4.2.25/bin
source /etc/profile
echo $PATH

（4）新建data、log、config目录，用于存储数据、日志、配置文件
（5）config目录，新建mongodb.conf配置文件，如下

dbpath=/data/software/mongodb/mongodb-linux-aarch64-ubuntu1804-4.2.25/data
logpath=/data/software/mongodb/mongodb-linux-aarch64-ubuntu1804-4.2.25/log/mongodb.log
port=27019
bind_ip=0.0.0.0
fork=true
logappend=true
auth=fals

（6）启动服务

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()
