    <p>Ok</p> <p>So I installed Apache <code>httpd</code> a while ago and have recently come back to it to try setup SSL and get it serving several different tomcat servers.</p> <p>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:</p> <ul> <li><code>example.com:8081</code></li> <li><code>example.com:8082</code></li> </ul> <p>I've successfully (back in Jan) used <code>mod_jk</code> to get <code>httpd</code> to serve those same Tomcat instances to <code>http://www.example.com:8090/dev</code> and <code>http://www.example.com:8090/demo</code> (8090 cos I've got another app running on 8080 via Jetty at this stage) using the following code in <code>httpd.conf</code>:</p> <pre><code>LoadModule jk_module modules/mod_jk.so JkWorkersFile conf/workers.properties JkLogFile logs/mod_jk.log JkLogLevel debug &lt;VirtualHost *:8090&gt; JkMount /devd* tomcatDev JkMount /demo* tomcatDemo &lt;/VirtualHost&gt; </code></pre> <p>What I'm not trying to do is enable SSL.</p> <p>I've added the following to <code>httpd.conf</code>:</p> <pre><code>Listen 443 &lt;VirtualHost _default_:443&gt; JkMount /dev* tomcatDev JkMount /demo* tomcatDemo SSLEngine on SSLCertificateFile "/opt/httpd/conf/localhost.crt" SSLCertificateKeyFile "/opt/httpd/conf/keystore.key" &lt;/VirtualHost&gt; </code></pre> <p>But when I try to restart Apache with <code>apachectl restart</code> (yes after shutting down that other app I mentioned so it doesn't toy with https connections) I continuously get the error:</p> <blockquote> <p>Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration. httpd not running, trying to start</p> </blockquote> <p>I've looked in the <code>httpd/modules</code> dir and indeed there is no <code>mod_ssl</code>, only <code>mod_jk.so</code> and <code>httpd.exp</code>.</p> <p>I've tried using yum to install <code>mod_ssl</code>, it says its already installed. Indeed I can locate <code>mod_ssl.so</code> in <code>/usr/lib/httpd/modules</code> but this is NOT the path to where I've installed <code>httpd</code> which is <code>/opt/httpd</code> and in fact <code>/usr/lib/httpd</code> contains nothing but the <code>modules</code> dir.</p> <p>Can anyone tell me how to install <code>mod_ssl</code> properly for my installed location of <code>httpd</code> so I can get past this error?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
