Hello friends, I am working on a Debian server in which I would like to setup 2 instances of Apache tomcat which will be load balanced by an Apache HTTP server(Do I require a http server? ). In-case one copy of Apache tomcat goes down, the other one will automatically comes online.
While I was creating a configuration for one of our server, I know how to relay requests based upon URL to Apache Tomcat, these are the 2 things I don't know. 1) Will this work with https? Reason I ask is, there are many pages which are served under https and the configuration which I have and shown below seems to be calling with http instead of https. 2) How to trigger the 2nd copy of tomcat. Here is what I have till now in Apache web server : // Below is the redirection for tomcat webapps. <VirtualHost *:80> ServerName www.domain_tomcat.de ServerAlias domain_tomcat.de ProxyRequests on ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> // I was thinking instead of routing to maintenance.html, I would start the other app, but that sounds quite hackish. I thought there might be a better way. ErrorDocument 503 /maintenance.html ErrorDocument 404 /maintenance.html ErrorDocument 500 /maintenance.html ProxyPass /maintenance.html ! // As you can see below, I am redirecting with http, which is my first point, will it automatically redirect to https, as tomcat webapp is using Spring-security and it has specific paths for which it must use https. ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/ <Location / > Order allow,deny Allow from all </Location> </VirtualHost> My tomcat config is rather simple : <Connector port="8080" proxyPort="80" redirectPort="443" protocol="org.apache.coyote.http11.Http11NioProtocol" compression="force" compressionMinSize="1024" connectionTimeout="20000" maxPostSize="5242880" URIEncoding="utf-8" compressableMimeType="text/html,text/xml,text/plain,text/css,text/ javascript,application/x-javascript,application/javascript"/> <Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxPostSize="5242880" SSLEnabled="true" maxThreads="200" compr$ compressionMinSize="1024" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="keystore.jks" keystorePass="PASSWORD" URIEncoding="utf-8" compressableMimeType="text/html,text/xml,text/plain,text/css,text/ javascript,application/x-javascript,application/javascript"/> I can setup a similar instance of Tomcat in another location if desired. But how can I handle the switching between them when one goes down. Kindly let me know. Thank you. :-)
