you use standalone ? I used wildfly domain.xml ,add <socket-binding name="ajp" port="${jboss.ajp.port:8159}"/> into domain.xml ,It seems exist some problem.
What your add seems can't slove my problem.
hi,dear @ Tomaz Cerar
today, I add the instance-id="${jboss.node.name}" in the undertow by CLI,I restart the wildfly and modcluster ,access http://192.168.157.57:6666/mod_cluster-manager
I Find that ,modcluster can identify the doamin control node ,server-one 、server-two...
but server-one、server-two ajp port are all default 8009 port.
for example:
and can only identify the slave 8009 port too with only server-one.
