Multiple Rice Instances on the Same Server
Given:
- You have multiple Tomcat instances, each with different shutdown and AJP ports
- You have an Apache server
- You want to host multiple Rice Standalone Servers on the same server like so:
Rice Standalone Server
CATALINA_HOME
Rice Configuration
application.url
Shutdown port
AJP port
A
/usr/share/tomcatA
/usr/local/rice/instanceA/rice-config.xml
https://rice-sandbox.sampleu.edu/instanceA 8500
8010
B
/usr/share/tomcatB
/usr/local/rice/instanceB/rice-config.xml
https://rice-sandbox.sampleu.edu/instanceB 8501
8011
