How to upgrade OpenSSL in CentOS 6.5 / Linux / Unix from source?

Question

How do I upgrade OpenSSL in CentOS 6.5?

I have used these commands, but nothings happens:

 cd /usr/src
 wget http://www.openssl.org/source/openssl-1.         


        

Answer 1

./config --prefix=/usr --openssldir=/usr/local/openssl shared

Try this config line instead to overwrite the default. It installs to prefix /usr/local/ssl by default in your setup when you leave off the prefix. You probably have "/usr/local/ssl/bin/openssl" instead of overwriting /usr/bin/openssl. You can also use /usr/local for prefix instead, but you would need to adjust your path accordingly if that is not already on your path. Here is the INSTALL documentation:

  $ ./config
  $ make
  $ make test
  $ make install

 [If any of these steps fails, see section Installation in Detail below.]

This will build and install OpenSSL in the default location, which is (for
historical reasons) /usr/local/ssl. If you want to install it anywhere else,
run config like this:

  $ ./config --prefix=/usr/local --openssldir=/usr/local/openssl
