Setting up squid as reverse proxy server for RTC 4 / tomcat installation
![]()
I am trying to set up squid (version 3.1.8) as reverse proxy server for an RTC 4.0.1 installation based on Apache Tomcat Version 7.0.25.
I am currently using the following squid.conf: ## setup acceleration proxy cache_replacement_policy heap GDSF memory_replacement_policy heap GDSF cache_dir aufs /opt/tmp 64000 256 256 cache_mem 16384 MB cache_store_log none cache_peer <RTC-SERVER_URL> parent 9443 0 no-query originserver name=httpsAccel ssl login=PROXYPASS sslflags=DONT_VERIFY_PEER cache_peer_access httpsAccel allow all coredump_dir /usr/local/squid/var/cache http_access allow all https_port 3128 cert=/etc/squid/server.pem accel key=/etc/squid/privkey.pem vhost refresh_pattern . 0 20% 4320 cachemgr_passwd disable all maximum_object_size 1024 MB maximum_object_size_in_memory 16 MB buffered_logs on visible_hostname <PROXY-SERVER-URL> as described in the article https://jazz.net/library/article/325 but when I try to connect to the <PROXY-SERVER_URL>:3128 I finally get a time-out (after quite a long time). I have tried lots of variations of this squid.conf (used different ports both for the proxy as well as for the RTC-server, added a defaultsite for the https_port) without success. When I use curl to connect to the proxy, even verbose-output does not give any hints what could be the cause of the hang: [thferres@ferres4 ~]$ curl -k https://<PROXY-SERVER-URL>:3128/ccm/ -v * About to connect() to <PROXY-SERVER-URL> port 3128 (#0) * Trying <PROXY-SERVER-IP>... connected * Connected to <PROXY-SERVER-URL> (<PROXY-SERVER-IP>) port 3128 (#0) * Initializing NSS with certpath: sql:/etc/pki/nssdb * warning: ignoring value of ssl.verifyhost * NSS error -5990 * Closing connection #0 * SSL connect error curl: (35) SSL connect error and the logs-files in /var/log/squid/ do not help either. I am just able to use the squid reverse proxy for an apache2 based http-Server (via SSL) or a tomcat6-based server (via http only). |

I followed that example in https://jazz.net/library/article/325, and it worked perfectly.
here is my test squid.conf (installed on Ubuntu 12.04 64bit) cache_replacement_policy heap GDSF memory_replacement_policy heap GDSF cache_dir aufs /usr/local/squid/var/cache 10240 256 256 cache_mem 1024 MB cache_store_log stdio:/usr/local/squid/var/logs/cachelog cache_peer 192.168.2.106 parent 9743 0 no-query originserver name=httpsAccel ssl login=PROXYPASS sslflags=DONT_VERIFY_PEER cache_peer_access httpsAccel allow all coredump_dir /usr/local/squid/var/cache http_access allow all https_port 9743 cert=/usr/local/squid/etc/server.pem accel key=/usr/local/squid/etc/privkey.pem vhost #https_port 9843 cert=/usr/local/squid/etc/server.pem accel key=/usr/local/squid/etc/privkey.pem vhost refresh_pattern . 0 20% 40320 cachemgr_passwd disable all maximum_object_size 5120 MB maximum_object_size_in_memory 16 MB buffered_logs on visible_hostname 192.168.2.7 you might want to enable the cache_store_log |
