How to upgrade OpenSSL on Centos 7 or RHEL 7
73,869 views
OpenSSL is a library that provides cryptographic functionality, specifically SSL/TLS for popular applications such as secure web servers, MySQl databases and email applications. The list parameters standard-commands, digest-commands, and cipher-commands output a list (one entry per line) of the names of all standard commands, message digest commands, or cipher commands, respectively, that are available in the present openssl utility.
You may need an operating system RHEL 7 or Centos 7 in your dedicated or vps server. Please make sure to set a hostname for your server and its dns is pointing to the IP address of the server.
Get the current version with “openssl version” and “yum info openssl” command :
# openssl version OpenSSL 1.0.1e-fips 11 Feb 2013
You can also check the available version in the vendors directory too.
# yum info openssl

To download the latest version of OpenSSL, do as follows:
# cd /usr/local/src # wget https://www.openssl.org/source/openssl-1.0.2-latest.tar.gz # tar -zxf openssl-1.0.2-latest.tar.gz
To manually compile OpenSSL and install/upgrade OpenSSL, do as follows:
# cd openssl-1.0.2a # ./config # make # make test # make install
If the old version is still displayed or installed before, please make a copy of openssl bin file :
# mv /usr/bin/openssl /root/ # ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
Now verify the OpenSSL version.
# openssl version OpenSSL 1.0.2e 3 Dec 2015
Note: Compiling Openssl major version may case issues with other system binaries. So please do the needfull to avoid the corruptions.
Thanks for the instructions. Those helped. Just one hint: for my CentOS 7 instance, before “make” I had to execute “make depend”
Thank you very much
For 1.1.0c install; you’ll need to do it as a non-root user + non-root user must have a sudo access;
1] as root :
yum -y remove openssl
[Note this ends up removing authconfig in centos 7]
2] as non-root user:
./config
make test
sudo make install
In Centos authconfig works only with ‘OpenSSL 1.0.1e-fips 11 Feb 2013’.
Question:
How do i get authconfig to install and work with openssl 1.1.0c ? –yes i need authconfig 🙂
Thank you. It works for Centos 6.5
Thanks for the instructions. Those helped!
The new version: cd openssl-1.0.2j
THis comment pretty much should be in red and bold at the TOP of the article — “Compiling Openssl major version may case issues with other system binaries. So please do the needfull to avoid the corruptions.”
It’s usefull, I success!
Thank you. This worked great!
Thanks for the blog. I have installed it in CentOS 6.9 and in the command line it shows the version correctly, but apache is taking the old version openssl. How can I fix this issue?
You need to compile apache with the option –with-openssl=/path-to-the-new-openssl
How do you reverse this process? I see that you moved the original version to /root, and added a link to the new path. I want to revert to the version installed by yum/rpm.
Very Thanks, .I have installed it and works well in comman line, but phpinfo says old openssl versión ??
You need to recompile php too
