How to install JBCS Apache 2.4.51 SP2 on RHEL9 from zipped archive file

Issue

• I get the following error when I run .postinstall. I did not get these errors with zipped JBCS Apache 2.4 on RHEL8.

# sh .postinstall
sed: can't read conf/httpd.conf: No such file or directory
sed: can't read conf.d/autoindex.conf: No such file or directory
sed: can't read conf.d/ssl.conf: No such file or directory
sed: can't read conf.d/manual.conf: No such file or directory
sed: can't read conf.d/welcome.conf: No such file or directory
useradd: user 'apache' already exists
sed: can't read conf.modules.d/00-base.conf: No such file or directory
grep: conf.modules.d/00-base.conf: No such file or directory

• The following message is logged in logs/http.log and Apache will not start:

httpd: Syntax error on line 358 of /opt/jbcs-httpd24-2.4/httpd/conf/httpd.conf: Syntax error on line 2 of /opt/jbcs-httpd24-2.4/httpd/conf.d/mod_proxy_cluster.conf: Cannot load /opt/jbcs-httpd24-2.4/httpd/modules/mod_proxy_cluster.so into server: /opt/jbcs-httpd24-2.4/httpd/modules/mod_proxy_cluster.so: undefined symbol: proxy_module
