Upgrade OpenSSL on CentOS 7

Raw

upgrade_openssl_on_centos_7.md

References :

I tried to upgrade openssl version 1.0.2 to 1.1.1, but this might also work for a higher version

Note that the commands need to be run sequentially!

cd /usr/local/src
wget https://www.openssl.org/source/openssl-1.1.1h.tar.gz
tar -zxf openssl-1.1.1h.tar.gz

cd openssl-1.1.1h
./config
make
yum install perl-Test-Simple

make test
make install

ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1

openssl version
