Structure of Installed Components¶

After installation, the following directory and file structure is created in the system:

Configuration Files:

/etc/nginx/
├── nginx.conf                          # Main configuration file
├── sites-available/                    # Available virtual host configurations
│   └── nginx71661.hostkey.in.conf
├── sites-enabled/                      # Active virtual hosts
│   └── nginx71661.hostkey.in.conf
├── conf.d/                             # Additional configurations
└── modules-enabled/                    # Enabled modules

System Files:

/etc/init.d/nginx                       # Init script
/etc/default/nginx                      # Environment variables
/etc/systemd/system/multi-user.target.wants/nginx.service

Logs and runtime:

/var/log/nginx/                         # Log directory
├── access.log                          # Access log
└── error.log                           # Error log
/run/nginx.pid                          # PID file of the process

SSL/TLS:

• Supported protocols: TLSv1, TLSv1.1, TLSv1.2, TLSv1.3
• Server cipher priority enabled

Logging:

• Access log: /var/log/nginx/access.log
• Error log: /var/log/nginx/error.log

Compression:

• Gzip enabled for traffic optimization

Virtual Hosts:

• Configurations loaded from /etc/nginx/conf.d/*.conf
• Active sites from /etc/nginx/sites-enabled/*

Getting Started After Deploying Nginx¶

After purchasing an order, you will receive a notification at the email address registered during signup when the server is ready for use. This notification will include the VPS IP address, as well as login credentials for connection. Our company's clients manage equipment through the server control panel and API — Invapi.

Authentication data, which can be found in the Info >> Tags tab of the server control panel or in the sent email:

• Login: root;
• Password: sent by email to your address upon server readiness after software deployment.

To use the service, connect to the server via SSH:

ssh root@<server_ip>

systemctl status nginx

Start:

systemctl start nginx 

systemctl stop nginx 

systemctl restart nginx

systemctl reload nginx
