I have installed Apache httpd a while ago and have recently come back to it to try setup SSL and get it serving several different tomcat servers.

At the moment I have two completely separate tomcat instances serving up to slightly different versions (one for Dev and one for demo say) my web app to two different ports;
mydomain.com:8081 and mydomain.com:8082

I've successfully (back in Jan) used mod_jk to get httpd to serve those same tomcat instances to www.mydomain.com:8090/dev and www.mydomain.com:8090/demo (8090 cos I've got another app running on 8080 via Jetty at this stage) using the following code in httpd.conf;

LoadModule jk_module modules/mod_jk.so
JkWorkersFile conf/workers.properties
JkLogFile logs/mod_jk.log
JkLogLevel debug

<VirtualHost *:8090>
JkMount /devd* tomcatDev
JkMount /demo* tomcatDemo
</VirtualHost>


What I'm not trying to do is enable SSL

I've added the following to httpd.conf

Listen 443
<VirtualHost _default_:443>
JkMount /dev* tomcatDev
JkMount /demo* tomcatDemo
SSLEngine on
SSLCertificateFile "/opt/httpd/conf/localhost.crt"
SSLCertificateKeyFile "/opt/httpd/conf/keystore.key"
</VirtualHost>


But when I try to restart Apache with "apachectl restart" (yes after shutting down that other app I mentioned so it doesn't toy with https connections) I continuously get the error;

"Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration. httpd not running, trying to start"

I've looked in the httpd/modules dir and indeed there is no mod_ssl, only mod_jk.so and httpd.exp.

I've tried using yum to install mod_ssl, it says its already installed. Indeed I can locate mod_ssl.so in /usr/lib/httpd/modules but this is NOT the path to where I've installed httpd which is /opt/httpd and in fact /usr/lib/httpd contains nothing but the modules dir.

Can anyone tell me how to install mod_ssl properly for my installed location of httpd so I can get past this error:
