Proxy Error Apache Glassfish
Contents |
Glassfish AS If "502 Proxy Error - The proxy server received apache error reading status line from remote server an invalid response from an upstream server." error occurs in ah00898: error reading from remote server returned by your Apache HTTP server logs, so there is a chance Glassfish application server closes TCP setenv proxy-nokeepalive 1 connection after timeout and every next client request to the proxy would get that error. The solution is to set "no keep alive" for Apache Load (20014)internal error: proxy: error reading status line from remote server Balancer: ProxyPass http://buggyappserver:7001/foo/ SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 after ProxyPass parameters and Apache server will reconnect Glassfish every time, but this variant should be slower… Enjoy!

Seeing a lot of 502 errors like this: Bad Gateway! The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /the/page.do. Reason: Error reading from remote server If you think this is a server error, please contact the webmaster. Error 502 Tomcat has plenty of threads, so it's not thread-constrained. We're pushing 2400 users via JMeter against the app. http://stackoverflow.com/questions/169453/bad-gateway-502-error-with-apache-mod-proxy-and-tomcat All the boxes are sitting inside our firewall on a fast unloaded network, so there shouldn't be any network problems. Anyone have any suggestions for things to look at or try? We're heading to tcpdump next. UPDATE 10/21/08: Still haven't figured this out. Seeing only a very small number of these under load. The answers below haven't provided any magical answers...yet. :) java apache tomcat mod-proxy share|improve this question edited Oct 21 '08 at 19:45 community wiki 2 revsAlex Miller I am facing this problem for some time during my running application –Uday A. Navapara Mar 12 '15 at 5:27 add a comment| 7 Answers 7 active oldest votes up vote 32 down vote Just to add some specific settings, I had a similar setup (with Apache 2.0.63 reverse proxying onto Tomcat 5.0.27). For certain URLs the Tomcat server could take perhaps 20 minutes to return a page. I ended up modifying the following settings in the Apache configuration file to prevent it from timing out with its proxy operation (with a large over-spill factor in case Tomcat took longer to return a page): Timeout 5400 ProxyTimeout 5400 Some backgound ProxyTimeout alone wasn't enough. Looking at the documentation for Timeout I'm guessing (I'm not sure) that this is because while Apache is waiting for a response from Tomcat, th
strange failure behaviours and undocumented inconsistencies have made this a major headache to figure out. What are we trying to achieve? Our test client -> Apache http://www.devwithimagination.com/2015/08/13/apache-as-a-reverse-proxy-to-glassfish/ HTTPD Proxy (SSL, with Client Cert) -> GlassFish (Retaining Client Cert authentication) What options https://bz.apache.org/bugzilla/show_bug.cgi?id=48315 are available? There are two approaches which appear to be available between Apache and GlassFish, both using Apache as the SSL terminator: AJP connector HTTP using auth-pass-through-enabled The implementation of the server side component also matters, as Java EE defines three methods of implementing a Web service: A JAX-RPC or JAX-WS service endpoint running in error reading a web container Stateless Session EJB as a JAX-RPC or JAX-WS web service Singleton Session EJB as a JAX-WS web service The source of this is section 5.3.2 of JSR-000109 Implementing Enterprise Web Services 1.4 Maintenance Release 3 for Evaluation. In addition to these there are also just plain Servlets deployed in a War file. As you can see, there are two containers in use for these methods: from remote server Web and EJB. Each of these containers have their own security systems which appear to not inconsistent in my tests, although I could not find documentation detailing this. Spoiler: Only the AJP connector behaves the same in the two containers, so it is the only option to allow proxied client certificate authentication in the EJB container. At the bottom of this article there is a conclusion detailing which implementation and container combinations work. The test setup I have created a project on my GitHub account containing sample code covering the first two web service implementation options as well as a plain servlet. Any configuration in this test is just as an example, obviously assess any options for security before applying to a production environment. The ApacheSiteConfig folder contains two files: proxytest.conf The site configuration used in testing RequiredModules.txt Text file detailing the required modules for this test. Example configuration files contain references to three servers: dev-lamp.local Apache/2.4.7 (Ubuntu) dev-gf3.local GlassFish Server Open Source Edition 3.1.2.2 dev-gf4.local GlassFish Server Open Source Edition 4.1 I did encounter a bug in GlassFish which required a patch. Our base site configuration in Apache requires “mod_ssl” to be enabled and these configuration options to set up SSL. DocumentRoot /home/wwwroot/dwi
