CF2023: Problem Apache 2.4.52 web server connector on Ubuntu 22

Hi,

I am having a problem with establishing Coldfusion 2023 connector to Apache 2.4.52 on Ubuntu 22.

 

I got this error message when I started Apache2 service.

apache2: Syntax error on line 228 of /etc/apache2/apache2.conf: Syntax error on line 4 of /etc/apache2/mod_jk.conf: Cannot load /etc/apache2/mod_jk.so into server: /etc/apache2/mod_jk.so: cannot open shared object file: No such file or directory

 

All configuration and existence is checked nothing is wrong but the Apache won't start.

Please help.

 

Thanks.

    As a sanity check, if you comment out line 4 of /etc/apache2/mod_jk.conf, does apache then at least start? (It should not be expected to serve cf pages, to be clear.) If it does start, the problem is clearly with that mod_jk.so file. (Remove the comment, assuming you have no need of apache to run without cf support.) 

     

    So first, how did that mod_jk.so file and those apache2.conf config lines get there? Did you run the cf wsconfig tool?

     

    Or did you copy those lines and that file (and related files) from some other server?

     

    Either way, you could have a problem of bit-level (using a 32-bit mod_jk.so with a 64-bit apache), or perhaps there could be a permissions problem. Can you show us the result of:

     

     

    ls -l /etc/apache2/mod_jk.so

    Thank you Charlie for your help and I commented line 4 and got different error message.

    This error message seems doesn't make sense.

    Aug 30 10:11:47 cf1 apachectl[179410]: AH00526: Syntax error on line 2 of /etc/apache2/mod_jk.conf:

    Aug 30 10:11:47 cf1 apachectl[179410]: Invalid command 'JkWorkersFile', perhaps misspelled or defined by a module not included in the server configuration

     

    The mod_jk.so is coming when I did "java -jar wsconfig.jar" from UI. Not copy from other server. I forgot to mention that I am running on Arm based Ubuntu. The Coldfusion 2023 is running perfectly but the connector is not. Is the connector not compatible w/ Arm?

     

    Thank you so much.

    The connector is C++, I think, and wouldn't be compatible with ARM. Do you really need Apache HTTPD in this setup? Maybe you can use the built-in Apache Tomcat web server that comes with ColdFusion.
