Php – Amazon Linux LAMP with php 5.5

I installed PHP 5.5 on my Amazon Linux VPS via the instructions here. The CLI is working fine.

I also had apache already installed and running via the httpd package. It was running without any issue.

I see that there is no mod_php in the list of available modules. Now when I try to restart httpd I get the error:

httpd: Syntax error on line 222 of /etc/httpd/conf/httpd.conf: Syntax error on line 6 of /etc/httpd/conf.d/php.conf: Cannot load /etc/httpd/modules/libphp5.so into server: /etc/httpd/modules/libphp5.so: symbol SSLeay_version, version OPENSSL_1.0.1 not defined in file libcrypto.so.10 with link time reference

I've looked up parts of this error, and the general advice seems to be to run

yum update openssl

However, when I run this I just get:

No packages marked for update

When I run install instead of update, I get:

Package 1:openssl-1.0.1e-4.55.amzn1.x86_64 already installed and latest version
Nothing to do

I'm not sure what else to do at this point.
