Apache 503 Error Page
Unavailable with mod_proxy for Tomcat 8 up vote 30 down vote favorite 4 I'm trying to integrate Tomcat with Apache. My aim is to redirect all the requests with http://localhost/myapp to http://localhost:8080 I followed this guide: http://tomcat.apache.org/tomcat-8.0-doc/proxy-howto.html My httpd.conf looks like this: Include conf.modules.d/*.conf LoadModule proxy_module modules/mod_proxy.so ProxyPass /myapp http://localhost:8080 retry=0 timeout=5 ProxyPassReverse /myapp http://localhost:8080 My server.xml in apache-tomcat looks like this: redirectPort="8443" proxyPort="80" /> Now when I try the url http://localhost/myapp, it gives 503 Service Unavailable error. Both Tomcat and Apache are up and running. The URL http://localhost:8080 works fine. Can there be an issue with file permissions? For tomcat the user and group are root/root and for httpd, the user and group are apache/apache Am I missing something or am I doing it wrong? Httpd version is 2.4.6 and Tomcat's version is 8.0 The httpd error logs: [proxy:error] [pid 19905] (13)Permission denied: AH00957: HTTP: attempt to connect to 127.0.0.1:8080 (localhost) failed [proxy:error] [pid 19905] AH00959: ap_proxy_connect_backend disabling worker for (localhost) for 0s [proxy_http:error] [pid 19905] [client ::1:51615] AH01114: HTTP: failed to make connection to backend: localhost Solved!

Just start the service which configured in port 8081 the problem will be solved. Comments (0) Leave a Comment Name: Reply to: Email: * Message: * Posting your comment...
