Inovalon is a healthcare cloud platform.

We run an EC2 instance with CentOs stream 9, nginx, OpenVPN, Docker and SSH.

Troubleshooting

Nginx Configuration File Structure

You don't need to configure Nginx upon installation. However, you should know the location of the configuration files and the Nginx root directory in case you need to modify the configuration.

Nginx configuration directory: /etc/nginx Nginx root directory: /usr/share/nginx/html Master/Global configuration file: /etc/nginx/nginx.conf

Nginx Management Commands

Other than starting and enabling the Nginx server commands (as discussed above), there are a few more commands that you will find helpful in managing the Nginx server. We are sharing some of them:

To stop the Nginx service, the command would be:

systemctl stop nginx

To restart the Nginx service, the command would be:

systemctl restart nginx

To disable the Nginx service, the command would be:

systemctl disable nginx

When you make any configuration changes, you will need to reload the firewall configuration. Here is the command you can use:

systemctl reload nginx

Source (installing nginx on CentOS)

Remote Access

Use the Private key to SSH into the EC2 instance.

ssh -I inovalon-key.pem ec2-user@x.x.x.x
