After developing a small application using Angular and an API with Spring Boot that includes an embedded Tomcat server, I decided to deploy them on a Raspberry Pi while configuring an SSL certificate with Let's Encrypt.
The deployment process involved installing Apache 2, creating a virtual host for the Angular part, and successfully installing an SSL certificate using Certbot. However, the API part is compiled in a .jar file, which I launch manually from the command line whenever the Pi starts up. The onboard Tomcat server listens on port 8080.
My current configuration looks like this:
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerName website.me
ServerAdmin [email protected]
DocumentRoot /var/www/html/website
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
SSLCertificateFile /etc/letsencrypt/live/website.me/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/website.me/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
RewriteEngine On
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]
RewriteCond %{REQUEST_URI} ^/rest/.*$
RewriteRule ^/rest/(.*) http://website.me:8080/rest/$1 [L]
RewriteRule ^ /index.html
</VirtualHost>
</IfModule>
Within my proxy.conf file, I have set up configurations for proxying as follows:
<IfModule mod_proxy.c>
LogLevel proxy:trace5
ProxyPreserveHost on
ProxyRequests Off
ProxyPassMatch .+\.html$ !
ProxyPassMatch .+\.js$ !
ProxyPass ^/rest/(.*)$ http://127.0.0.1:8080/rest/$1
ProxyPassReverse ^//rest/(.*)$ http://127.0.0.1:8080/rest/$1
</IfModule>
Despite setting up redirections from port 80 to 443 and routing requests from "/rest/*" to port 8080, I encountered a cross-origin security error, making the setup ineffective.
I have attempted to configure a proxy and enable cross-origin access in Apache2 without success. Any suggestions or ideas would be greatly appreciated.
