Environment Deployment

Start the exporter process and create a listening port number on the local host.
Modify the configuration file prometheus.yml on the Promethues server and add the information about the started exporter to the file. For example:
```
 scrape_configs:
 ...
   - job_name: 'opengauss_exporter'
     static_configs:
     - targets: ['127.0.0.1:9187']
 ...
```

The exporter component uses HTTPS for communication by default. Therefore, you need to provide the SSL certificate and key file by default through --ssl-keyfile and --ssl-certfile. To disable HTTPS, you can run the --disable-https command.

NOTE: The default communication protocol used by openGauss is incompatible with PostgreSQL. As a result, the PostgreSQL-based Python driver psycopg2-binary installed using the PyPI source cannot connect to the openGauss database. Therefore, you need to compile psycopg2 or modify GUC parameters for adaptation. You can also download psycopg2 compiled based on openGauss from the openGauss official website. (Typically, a version compiled for Python 3.6 is provided. User need to check the version number before using it.)
Download the openGauss Python driver from the official website: https://opengauss.org/en/download/
For details about the adaptation of the Python driver, see the openGauss operation guide at: https://mp.weixin.qq.com/s/2TobUQKtw0N9sBpMZJr6zw
