In apache, the module mod_jk not changes IP of hostname when occurs changing of IP on DNS.
Version of apache: Server version: Apache/2.2.15 (Unix) Server built: Aug 2 2013 08:02:15 Version mod_jk: 1.2.37 Example: workers.properties worker.portalconsultoras_prd.type=ajp13 worker.portalconsultoras_prd.host=hostexample.com.br worker.portalconsultoras_prd.port=8009 This configuration works fine. But, when occurs change ip in the host name in DNS, the module md_jk starts fail to connect. Follow below the log of mod_jk: [Wed Sep 18 12:00:33 2013] [5315:140659824723936] [info] jk_open_socket::jk_connect.c (627): connect to 107.xx.xx.220:8009 failed (errno=115) [Wed Sep 18 12:00:33 2013] [5315:140659824723936] [info] ajp_connect_to_endpoint::jk_ajp_common.c (995): Failed opening socket to (107.xx.xxx.220:8009) (errno=115) [Wed Sep 18 12:00:33 2013] [5315:140659824723936] [error] ajp_send_request::jk_ajp_common.c (1630): (portalconsultoras_prd) connecting to backend failed. Tomcat is probably not started or is listening on the wrong port (errno=115) I would like a configuration of apache that avoid this problem. Looking for the solutions in google, have turn on the "HostnameLookups", but is inefficient. Thanks! -- Atenciosamente, Tiago Braga Machado
