Webserver Setup

Introduction

Some scripts to help with the deployment of webservers.

Add site to Nginx

This will take two parameters the first is the website name and the second is the IP address there is no need to add seaoffate.local or .net. this script will create four configs.

• sitename.seaoffate.local as http
• sitename.seaoffate.local as https
• sitename.seaoffate.net as http
• sitename.seaoffate.net as https

It should enable both of the http: versions (.local & .net) but it will not enable the https: so we have some time to get the certs done before ssl is deployed. note that the .local is sharing the same certificate amongst all of the .local websites that are being deployed here. The script is on Raisin on the root of nigel. if it is lost it can be deployed again from this:

#!/bin/bash

# Script to configure Nginx as a reverse proxy

# Get website name, IP address from command line
WEBSITE_NAME="$1"
FORWARD_IP="$2"

# Check if parameters are provided
if [ -z "$WEBSITE_NAME" ] || [ -z "$FORWARD_IP" ]; then
  echo "Usage: sudo $0 <website_name> <forward_ip>"
  exit 1
fi

# Define domain names
DOMAIN_LOCAL="$WEBSITE_NAME.seaoffate.local"
DOMAIN_NET="$WEBSITE_NAME.seaoffate.net"

Revove Website from Proxy (Raisin)

We all make mistakes and we have to recover. This script will remove mistakes created by the website_fwd_config.sh above call it with

./remove_nginx_website.sh sitename

sitename is the site that needs to be removed, only the host potion needs to be supplied do not put in the .seaoffate.let or .seaoffate.local because it will remove all four configs(.local & .net and http ang https). All four website configs created above will be removed from /etc/nginx/sites-available & sites.enabled.

#!/bin/bash

# Script to remove an Nginx reverse proxy website configuration

# Get website name from command line
WEBSITE_NAME="$1"

# Check if website name is provided
if [ -z "$WEBSITE_NAME" ]; then
  echo "Usage: sudo $0 <website_name>"
  exit 1
fi

# Define domain names
DOMAIN_LOCAL="$WEBSITE_NAME.seaoffate.local"
DOMAIN_NET="$WEBSITE_NAME.seaoffate.net"

# Define configuration file paths
CONFIG_LOCAL="/etc/nginx/sites-available/$DOMAIN_LOCAL"
CONFIG_LOCAL_SSL="/etc/nginx/sites-available/$DOMAIN_LOCAL-ssl"
CONFIG_NET="/etc/nginx/sites-available/$DOMAIN_NET"
CONFIG_NET_SSL="/etc/nginx/sites-available/$DOMAIN_NET-ssl"
SYMLINK_LOCAL="/etc/nginx/sites-enabled/$DOMAIN_LOCAL"
SYMLINK_NET="/etc/nginx/sites-enabled/$DOMAIN_NET"

# Remove configuration files
sudo rm -f "$CONFIG_LOCAL" "$CONFIG_LOCAL_SSL" "$CONFIG_NET" "$CONFIG_NET_SSL"

# Remove symbolic links (disable sites)
sudo rm -f "$SYMLINK_LOCAL" "$SYMLINK_NET"

# Restart Nginx
sudo systemctl restart nginx

echo "Nginx website configuration removed."
echo "Website: $WEBSITE_NAME"
echo "Domains: $DOMAIN_LOCAL and $DOMAIN_NET"

# List sites-available directory
