POWhy am I getting an Apache Proxy 503 error?
text
Body
copied!<p>My server was doing just fine up until yesterday. It was running <a href="http://www.redmine.org/" rel="noreferrer">Redmine</a>, and it was the happiest little server <strong>until</strong> my "friend" imported a SQL table that my little guy couldn't take. Unfortunately, after an hour of trying to get the lil guy to respond, we had to power cycle him.</p> <p>Now after restart, we get a 503 error when trying to visit the domain connected to Redmine. It's hooked up to a <a href="https://rubygems.org/gems/mongrel" rel="noreferrer">Mongrel</a> daemon, and we use Apache Proxy to direct all connections to the port Redmine is running on.</p> <p>Using Lynx on the server (<code>http://localhost:8000</code>) you can see the Ruby application working fine. But this bit is not working in my Apache configuration file:</p> <pre><code><VirtualHost *:80> ServerName sub.example.com ProxyPass / http://localhost:8000 ProxyPassReverse / http://localhost:8000 ProxyPreserveHost on LogLevel debug </VirtualHost> </code></pre> <p>Here's the error log output for Apache:</p> <pre> [debug] mod_proxy_http.c(54): proxy: HTTP: canonicalising URL //localhost:8000 [debug] proxy_util.c(1335): [client 216.27.137.51] proxy: http: found worker http://localhost:8000 for http://localhost:8000/ [debug] mod_proxy.c(756): Running scheme http handler (attempt 0) [debug] mod_proxy_http.c(1687): proxy: HTTP: serving URL http://localhost:8000/ [debug] proxy_util.c(1755): proxy: HTTP: has acquired connection for (localhost) [debug] proxy_util.c(1815): proxy: connecting http://localhost:8000/ to localhost:8000 [debug] proxy_util.c(1908): proxy: connected / to localhost:8000 [debug] proxy_util.c(2002): proxy: HTTP: fam 2 socket created to connect to localhost [error] (13)Permission denied: proxy: HTTP: attempt to connect to 127.0.0.1:8000 (localhost) failed [error] ap_proxy_connect_backend disabling worker for (localhost) [debug] proxy_util.c(1773): proxy: HTTP: has released connection for (localhost) </pre>
