I am running a 10.04LTE server where I do want to upgrade openssl for apache.

Therefore I downloaded openssl 1.0.2c and apache 2.2.29 and compiled both. The server is starting, but is using the old ssl version:

curl --head http://localhost
HTTP/1.1 200 OK
Date: Mon, 22 Jun 2015 06:00:06 GMT
Server: Apache/2.2.29 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8k
Last-Modified: Sun, 18 Mar 2012 19:56:07 GMT

However, Openssl is installed in new version:

/usr/local/ssl/bin/openssl version
OpenSSL 1.0.2c 12 Jun 2015

While the original version stayes in place:

openssl version
OpenSSL 0.9.8k 25 Mar 2009

I compiled apache with:

./configure --with-included-apr --prefix=/usr/local/apache2 --enable-so     
--enable-rewrite --with-ssl=/usr/local/ssl --enable-ssl=shared
--enable-deflate --enable-expires --enable-headers 

Apache did not start before I included:

LoadModule ssl_module /usr/lib/apache2/modules/mod_ssl.so

According to the mod ssl website this is only available for apache 1.x

Not sure what is going wrong here. Thank you for any help!


The problem is that your Apache installation is unable to link the shared libraries of your new OpenSSL installation. Run the command ldd /usr/local/apache/modules/mod_ssl.so (with the apporpriate path to your mod_ssl.so). You'll see that mod_ssl.so is not linking to the libraries in /usr/local/ssl/lib

You have a couple options to fix the problem:

Option #1 - Link in the libraries:

Open /etc/ld.so.conf.d/local.conf for editing and add the following line: /usr/local/openssl/lib

Re-compile Apache (remember to make clean) and it should work.

If that doesn't work. You could also try specifying LDFLAGS directly with your configure command:

LDFLAGS=-L/usr/local/ssl/lib \ ./configure --with-included-apr --prefix=/usr/local/apache2 --enable-so     
--enable-rewrite --with-ssl=/usr/local/ssl --enable-ssl=shared
--enable-deflate --enable-expires --enable-headers

Option #2 - Upgrade the system OpenSSL:

Re-install OpenSSL with the config line ./config --prefix=/usr --openssldir=/usr/local/openssl shared

When the prefix is not specified in your config line, the OpenSSL installer will default to /usr/local/ssl.

Quick install instructions:

cd /usr/local/src
wget https://www.openssl.org/source/openssl-1.0.2-latest.tar.gz
tar -zxf openssl-1.0.2*
cd openssl-1.0.2*
./config --prefix=/usr --openssldir=/usr/local/openssl shared
make test
make install
  • I dont undertand why openssl should be installed in /usr The library is now correctly installed in /usr/local/ssl but apache is using some old version despite configuring --with-ssl=/usr/local/ssl – merlin Jun 23 '15 at 19:36
  • Thank you! The command ldd helped to solve the problem. I have included the old mod_ssl in the apache httpd.conf. The right one is the following: /usr/local/apache2/modules/mod_ssl.so which is now using the new ssl library – merlin Jun 23 '15 at 20:12
  • Ahh interesting, I'm glad you got it solved! – Elliot B. Jun 23 '15 at 20:14
