php is running on my server, though I'm unable to get it to run command line. I'm running this file:

echo "done";

using this command:

php test.php

When I do, I get this error:

php: /usr/lib64/libssl.so.10: no version information available (required by php)

Any ideas why this might be? The server is live, so I'm hoping to understand what's going on here before making any changes that might break my setup. I need php to run command line, so I can get an email receiving script working. I'm on nginx, running php-fpm.

Thanks for any pointers -

This means that the library version number is lower on the shared object.

Maybe you have two different openssl libraries on your system. You may have linked with one but php is using the other.


$ find / -name libssl.so*

and have a look at the versions installed. Also have a look at

$ ldd `which nginx` | grep ssl

to find the library used by nginx.

and check

$ ldd `which php` | grep libssl

to find out what library php is using.

What operating system are you on?

Can you try upgrading to the latest openssl package provided by your OS vendor and restart nginx so that it uses the updated library?

And quoting from nginx.com/blog

If you have compiled NGINX yourself, you may have statically linked the openssl libraries. The ldd test will reveal no dependencies on the operating system libssl.so library. nginx -V will give you the compile-time options which should reveal the options you used.

  • Okay, I see these: /usr/lib64/libssl.so.1.0.0 /usr/lib64/libssl.so.1.0.1e /usr/lib64/libssl.so.10 /usr/lib64/libssl.so /root/install/openssl-1.0.1g/libssl.so.1.0.0 /root/install/openssl-1.0.1g/libssl.so The output of the second is: libssl.so.10 => /usr/lib64/libssl.so.10 (0x00007fe26b2de000) What am I looking at here? Is libssl.so.10 what's being used by everything on the system? What can be safely deleted? – user2044774 Aug 28 '14 at 17:19

This is what I done in my test system and its working fine.Looking at the above output it look like you are using so many version of openssl. Please try to figure which one you are using at the same time remove the one not in use and make sure it will not break the other functionality

        php test.php

        ldd `which php`|grep -i libssl
        libssl.so.10 => /usr/lib64/libssl.so.10 (0x0000003edcc00000)

        rpm -qf /usr/lib64/libssl.so.10
