How to install mod ssl for Apache httpd

Question

Ok  So I 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    example com 8081 example com 8082   I ve successfully  back in Jan  used mod jk to get httpd to serve those same Tomcat instances to http   www example com 8090 dev and http   www example 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   lt VirtualHost   8090 gt      JkMount  devd  tomcatDev     JkMount  demo  tomcatDemo  lt  VirtualHost gt    What I m not trying to do is enable SSL   I ve added the following to httpd conf   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    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

I found I needed to enable the SSL module in Apache (obviously prefix commands with sudo if you are not running as root):

a2enmod ssl

then restart Apache:

/etc/init.d/apache2 restart

Try installing mod ssl using following command   yum install mod ssl   and then reload and restart your Apache server using following commands   systemctl reload httpd service systemctl restart httpd service   This should work for most of the cases

I used   sudo yum install mod24 ssl   and it worked in my Amazon Linux AMI

Are any other LoadModule commands referencing modules in the  usr lib httpd modules folder  If so  you should be fine just adding LoadModule ssl module  usr lib httpd modules mod ssl so to your conf file   Otherwise  you ll want to copy the mod ssl so file to whatever directory the other modules are being loaded from and reference it there
