File and Directory Structure¶

The following paths are used in the system for storing data and configurations:

• /opt/solr/data — Apache Solr data directory.

• /root/nginx — Nginx working directory (contains compose.yml).

• /data/nginx/user_conf.d — Directory containing user configuration files for Nginx.

Application Installation Process¶

Deployment is performed by running a Docker container using the solr:9 image. The application operates in host network mode, providing direct communication with host ports. Additionally, an Nginx + Certbot stack is installed and configured to ensure operation via the HTTPS protocol.

Docker Containers and Execution¶

The following containers are used for system operation:

• apache-solr{Server_ID}.hostkey.in — Main Apache Solr application container (image solr:9).

• nginx — Proxy server for handling SSL traffic (image jonasal/nginx-certbot:latest).

Permissions Settings¶

The following access rights are set to ensure correct database operation and file storage:

• Directory /opt/solr/data:

• Owner: 8983

• Group: 8983

• Permissions: 0755

Configuration Files and Data Location¶

Available Connection Ports¶

• Port 443 — Access to the application via a secure HTTPS connection.

• Port 3000 — Internal Solr application port.

Starting and Stopping the Application¶

Proxy server management is performed via Docker Compose in the /root/nginx directory:

• Start: docker compose up -d (executed from /root/nginx).

• Stop: Docker container management.
