upgrade OpenSSL from 0.9.8w to 1.0.0i or 1.0.1a on Linux server [duplicate]

Question

I want to upgrade OpenSSL from 0.9.8w to 1.0.0I or 1.0.1a.

I am using

os.name  Linux  
os.version  2.6.18-164.9.1.el5 

Answer 1

It is easy to pull the source using git and to build it yourself.

mkdir ~/openssl
cd ~/openssl
git clone git://git.openssl.org/openssl.git .

From the INSTALL document:

./config
make
make test
make install

The last command should be done as a superuser.

note that git checkout xxx can be used to pick the version you want to use.
