Coldfusion 2018 on Centos 7 failing to setup Apache connector

I’ve installing CF2018 on a new server, which is installed and running, I can see it if I run ps aux | ack -i coldfusion

$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

$ httpd -v
Server version: Apache/2.4.6 (CentOS)
Server built:   Jul 29 2019 17:18:49

UPDATE

I had clearly broken something so I’ve removed earlier errors, but I’m still getting issues with the connector.

I have removed all references and files relating to mod_jk from /etc/httpd/conf, reinstalled CF then re-ran the connector.

It’s installed successfully with this command:

$ sudo ./wsconfig -ws Apache -dir /etc/httpd/conf

I have the dir at /opt/coldfusion2018/config/wsconfig/1 setup but I’m now getting these errors:

$ pwd
/opt/coldfusion2018/config/wsconfig/1

$ tail mod_jk.log
[error] ajp_service::jk_ajp_common.c (3000): (cfusion) connecting to tomcat failed (rc=-3, errors=583, client_errors=0).

I have no idea where port 8018 has come from, I thought tomcat used 8500 by default

UPDATE 2

If I visit my site with :8500 on the end I can get into the CFIDE, so it’s CF is running and that port is accessible

UPDATE 3

I’ve found this in my server.xml file, tried setting the port to both 8009 and 8018 and it seems to make no difference to the errors in the mod_jk.log


    <!-- Define an AJP 1.3 Connector on port 8009 -->
        <!-- begin connector -->
    <Connector port="8009" packetSize="65535" protocol="AJP/1.3"  redirectPort="8451" tomcatAuthentication="false" maxThreads="500" connectionTimeout="60000"/>
    <!-- end connector -->

    The problem was SELinux blocking port 8018, I actually asked my hosting provider Secura to look into this for me and they fixed it (based on all the information I'd found from piyush's answer)

    I had to allow port 8018 in SELinux

    semanage port -a -t http_port_t -p tcp 8018

    Pete,

    What’s the OS and the webserver’s version?

    Did you try passing the parameters other than dir, explicitly, like so:

    sudo ./wsconfig -ws Apache /opt/apache2/conf -bin /opt/apache2/bin/httpd -script /opt/apache2/bin/apachectl -dir -v

    ..and the coldfusion process need not be running for the connector to be configured.

    8018 is the default AJP port that the conector uses to talk to tomcat. 8500 is the default HTTP port that you’d use when you access the CF admin console.
    You initially reported error when configuring the connector. Is that resolved.
    Did you check the wsconfig log to see if there were errors configuring the connector.

    The modjk log excrepts you’ve shared more recently simply indicate that CF is not running, or at the least, not listening on the default AJP port.
