Subject Re: [users@httpd] what's the minimum version of openssl required by 2.2.29?
Date Fri, 06 Feb 2015 22:15:52 GMT

Thanks for the helpful reply.

After reading it I realized that I’m indeed compiling on a system that’s different than
the runtime which led to my issue.

In my case, apache was compiled with latest CentOS with a newer openssl version. The runtime
was an older version of CentOS with an older version of openssl. The RPM distribution (from
which the compiled Apache came from) also didn’t specify the newer “Requires” version
of openssl.

I recently upgraded apache from 2.2.27 to 2.2.29 and received the
following error on startup:

/usr/lib64/ no version information available

After some searching, I determined that openssl needed to be upgraded.

On CentOS 6.1 (yes, I know it¹s old):

The previous version was: OpenSSL 1.0.0-fips 29 Mar 2010

After upgrading via Œyum install openssl¹, the new version is: OpenSSL
1.0.1e-fips 11 Feb 2013

This leads me to the question: What¹s the minimum version required by
Apache 2.2.29?

You don't specify if you upgraded through your distribution, or compiled manually, in any
case httpd will depend on openssl libraries to which it was compiled, if none were specified
it should be using the libraries present in the system when you ran ./configure.

If you upgraded with a distribution upgrade it is hard to believe dependencies are not met
or there are library versions mismatches.

It looks to me as if you are installing different packages from different sources.

So I believe it is better if you focus on meeting your distribution dependencies, or if you
compiled manually with an external openssl version to add the /path/to/openssl/lib to your
libpath or in envvars so httpd will find the appropiate openssl libraries
