# NGINX CONFIG DEPLOYMENT SCRIPT (v3)
|
|
#
|
|
# This script securely copies NGINX configuration files to a remote server.
|
|
# It handles "Permission Denied" errors by first uploading files to a
|
|
# temporary directory, and then using `sudo` to move them to the
|
|
# protected /etc/nginx/ directory.
|
|
#
|
|
# INSTRUCTIONS:
|
|
# 1. Edit the `REMOTE_USER` and `REMOTE_HOST` variables.
|
|
# 2. Make the script executable: chmod +x <script_name>.sh
|
|
# 3. Run the script: ./<script_name>.sh
|
|
