mod_jk not able to connect Apache and tomcat

Question

I am not able to connect my Apache to tomcat servers. Below are the version details. mod_jk/1.2.39 Apache-2.4.41 tomcat-9.0.31

I have created Workers.properties file and mentioned my hostname and AJP port ie 8009 and also enabled Ajp connectors from tomcat side. Issue I am facing is mod_jk is not connecting to host that I have provided in workers.properties file. Instead of that it is connecting to 0.0.0.0. Below is the error from mod_jk.log

[Wed May 27 12:52:00 2020] [6902:140379841652544] [info] init_jk::mod_jk.c (3383): mod_jk/1.2.39 initialized

I have checked I can access my tomcat servers and it's running fine. Below is the Ajp connectors from tomcat server

<Connector protocol="AJP/1.3"
               address="::1"
               port="8009"
               redirectPort="8443" />

Is there anything I am missing or is it some kind of fat bug involve with this version of mod_jk? Any kind of Suggestion and Help will be appreciated.

Thanks, Anshu

Answer 1

Start tomcat server on IP address instead of 0.0.0.0.

<Connector protocol="AJP/1.3"
               address="IP-address"
               port="8009"
               redirectPort="8443" />

Use tomcat-adress and Port in worker.properties. Restart tomcat and Apache service. Also make sure that port 8009 is open between Apache and tomcat server.
