Provide Secure Backend for PPT (Linux)

To use https, you need a certificate. To add that certificate to your connector e.g. you replace <mycert.crt>, <mykey.key> with appropriate values.

openssl pkcs12 -export -in mycert.crt -inkey mykey.key
                        -out keystore.p12 -name tomcat -CAfile myCA.crt
                        -caname root -chain

You have to adapt the ppt.url property in the The poolparty.properties File file.

For this setup, a second Connector has to be configured in the Tomcat server configuration:

The secure and scheme attributes have to be set to indicate to the PoolParty application that the connection is secured. The following configuration example uses a thirdparty webserver for handling the ssl termination. The attributes proxyName and proxyPort are set to the real address connected to by client browsers. All other attributes are copied from the normal HTTP Connector.

    <Connector
        URIEncoding="UTF-8"
        executor="tomcatThreadPool"
        acceptCount="400"
        port="8443" 
        protocol="HTTP/1.1" 
        enableLookups="false"
        connectionTimeout="3000" 
        compression="on"
        compressionMinSize="2048"
        noCompressionUserAgents="gozilla, traviata"
        compressableMimeType="text/html,text/css,application/javascript"
        secure="true" scheme="https"
                SSLEnabled="true"
                keystoreFile="/opt/poolparty/tomcat/conf/keystore.p12"
                keystorePass="<changeit>"
                keystoreType="PKCS12"
                proxyName="vocabulary.example.org" 
        proxyPort="443" />

Since the Tomcat connector's port is 8443, the configuration for nginx would look as in this example:

upstream vocabulary-443 {
  server 10.0.0.12:8443;
  keepalive 4;
}
server {
  server_name  vocabulary.domain.com;

  listen 80;
  
  location / {
    proxy_http_version 1.1;
    proxy_set_header Connection "";
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto http;
    proxy_set_header Host $http_host;
    proxy_pass http://vocabulary;
  }
#redirect all secured Backend URLs to https
  location /PoolParty {
    return 301 https://vocabulary.example.org$request_uri;
  }
  location /extractor {
    return 301 https://vocabulary.example.org$request_uri;
  }
  location /solr {
    return 301 https://vocabulary.example.org$request_uri;
  }
}
upstream vocabulary-443 {
        server 10.0.0.12:443;
        keepalive 4;

        server_name vocabulary.example.org;
        listen 443 ssl;
