Centos mod_jk works for http but not https

Question

Using Apache 2.4.6 (Centos 7) + compiled mod_jk 1.2.42 + jboss and following config: /etc/httpd/conf/worker.properties:

# Worker Default Values worker.default.type=ajp13 worker.default.socket_keepalive=true worker.default.connect_timeout=10000 worker.default.ping_mode=I worker.default.connection_ping_interval=300 worker.list=sl_jboss-worker # Set properties for worker (ajp13) worker.sl_jboss-worker.type=ajp13 worker.sl_jboss-worker.host=centos7.test.pl worker.sl_jboss-worker.port=8009

/etc/httpd/conf.d/zl-jboss.conf:

LoadModule jk_module modules/mod_jk.so
JkWorkersFile /etc/httpd/conf/worker.properties
JkLogFile logs/mod_jk.log
JkShmFile /var/run/httpd/mod_jk.shm
JkLogLevel debug
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "

<VirtualHost *:80>
    ServerName centos7.test.pl
    JkMount /* sl_jboss-worker
</VirtualHost>

<VirtualHost *:443>
    ServerName centos7.test.pl
    SSLEngine on
    SSLCertificateFile /etc/pki/tls/certs/ca.crt
    SSLCertificateKeyFile /etc/pki/tls/private/ca.key
    JkMount /* sl_jboss-worker
</VirtualHost>

When I try to use HTTP - the content from jboss server is displayed, if I use HTTPS - then I get 404 error in browser and following error in mod_jk.log

Answer 1

The solution needed adding

JkMountCopy On

Into /etc/httpd/conf.d/ssl.conf, like:

##
## SSL Virtual Host Context
##
<VirtualHost _default_:443>
JkMountCopy On

The sad thing is that this need go here (to _default_ config), and the option JkMountCopy All does not solve it. Still don't know if its intended behaviour or a bug.
