Hi Everyone,

So still having issues with mod_jk. I have downloaded

wget
http://www.eu.apache.org/dist/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.46-src.tar.gz
wget
http://www.eu.apache.org/dist/tomcat/tomcat-connectors/jk/tomcat-connectors-1.2.46-src.tar.gz.sha1

and make install, and everything seems fine

I then edited the httpd.conf file and added

LoadModule jk_module modules/mod_jk.so

JkWorkersFile "/etc/httpd/conf/workers.properties"
JkLogFile     "/var/log/mod_jk.log"
JkLogLevel  info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions     +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat     "%w %V %T"

then I edited workers.properties and added

worker.list=app1,app2

worker.app1.type=ajp13
worker.app1.host=app1.example.com
worker.app1.port=8201
worker.app1.socket_timeout=10

worker.app2.type=ajp13
worker.app2.host=app2.example.com
worker.app2.port=8201
worker.app1.socket_timeout=10

Then when I restart Apache using systemctl restart httpd I get

Job for httpd.service failed because the control process exited with error
code. See "systemctl status httpd.servic
e" and "journalctl -xe" for details.

So checking mod_jk log I see

[Wed Nov 21 15:54:19 2018] [11957:140478724515968] [warn]
jk_map_handle_duplicates::jk_map.c (456): Duplicate key $

and the httpd log last entries are

I am not sure if the first 3 are connected to mod_jk, I included them for
those who know far more then me (almost everyone I suspect) just in case

And ideas, hints or thoughts?

Thanks!

Lou
