Configure websocket proxy on Linux

Hi All,

I tried to configure the websocket proxy on Linux with this following command

[joseph@ip-10-0-0-22 bin]$ sudo java -jar /opt/coldfusion2016/cfusion/lib/wsproxyconfig.jar -ws Apache -dir /etc/httpd/conf -port 8759

and I got this error below:

Error occurred while running proxy configuration tool. Reason : WebSocket Proxy can be only configured with worker mpm.

* Apache:

Server version: Apache/2.4.6 (CentOS)

Server built:   Oct 19 2017 20:39:16

* Java:

openjdk version "1.8.0_201"

OpenJDK Runtime Environment (build 1.8.0_201-b09)

OpenJDK 64-Bit Server VM (build 25.201-b09, mixed mode)

* Coldfusion 2016

Please help.

Thank you in advance.

Joseph.
