Having verified the PHP installation, turn on the OpenSSL support by uncommenting the line. In php.ini, which you will find in the PHP directory (I'll assume you made that c:/PHP). Next check the location of phpopenssl.dll, which you should find in c:/PHP/ext. Also in php.ini find the key extensiondir, and change. CentOS 5:: Adding OpenSSL Extension After Installing PHP With Yum. Managed to install CouchDB on the server at work after doing some fiddling due to. Jun 22, 2017 How To View Current PHP Modules. When logged into your server via SSH, type in the following command. Yum list installed.php. This will populate a list, like the following, showing you all the current PHP modules installed. Repository information has been removed from the above example. For an explanation of extension loading and why we do not add the extensions to php.ini, see the section on loading the drivers. The following instructions install PHP 8.0 by default using pecl install, if the PHP 8.0 packages are available. You may need to run pecl channel-update pecl.php.net first. Some supported Linux distros default to PHP.

Hi there, today I would like to show you how to install latest version of OpenSSL (1.1.1c) on CentOS 7
Do I need latest version of OpenSSL?
Install ZIP extension for php on CentOS. I will install new version of php on new server. OpenSSL PHP extension have to be enabled to use extension repository.
In general - you don't. Default version is doing great job and it's secure. I needed it for compiling Apache HTTP with HTTP/2 support back then and now I'm using new version every time it's released. If you need it for any other reason, this tutorial is for you:)
How to check current version of OpenSSL?
In order to check current version of installed package you need to execute following command:
It will print out version of installed package like OpenSSL 1.0.2k-fips 26 Jan 2017
How to install latest version of OpenSSL?
I compile OpenSSL from source code. In order to compile it successfully you need to install some tools that will help you compile it:
It will install compiler and few other libraries that are required to compile OpenSSL.
Next download latest version of OpenSSL source code. I like to use releases page on GitHub. I choose the version without FIPS simply because I don't need compatibility with it. And I think that it's a bit more secure to have OpenSSL without FIPS, as fixes are usually included much faster in regular version than in FIPS version. If you want to read more about it, use this link.
In order to download source code, use following command:
Source code comes in compressed package. In order to decompress it use following command:
Now it's time to configure and compile OpenSSL:
prefix and openssldir sets the output paths for OpenSSL. shared will force crating shared libraries and zlib means that compression will be performed by using zlib library
It is worth to run the tests to see if there are any unexpected errors. If there are any, you need to fix them before installing library.
In order to install library you need to execute:
Once the OpenSSL is installed, you can remove the sources and tar.gz package.
Add new version to PATH
After the installation you will probably want to check the version of OpenSSL but it will print out old version. Why? Because it's also installed on your server. I rarely override packages installed via yum. The reason is that when there is new version of OpenSSL and you will install it via yum, it will simply override compiled version, and you will have to recompile it again.
Instead of overriding files I personally like to create new profile entry and force the system to use compiled version of OpenSSL.
In order to do that, create following file:
and paste there following content:
Save the file and reload your shell, for instance log out and log in again. Then you can check the version of your OpenSSL client. Or maybe...
Link libraries
Or maybe you will get an error with loading shared libraries? In order to fix that problem we need to create an entry in ldconfig.
Create following file:
And paste there following contents:
We simply told the dynamic linker to include new libraries. After creating the file you need to reload linker by using following command:
And volia! Check the version of your OpenSSL now. It should print out OpenSSL 1.1.1c 28 May 2019
OpenSSL is a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols. It is also a general-purpose cryptography library.
OpenSSL is used by many programs like Apache Web server, PHP, and many others providing support for various cryptographic algorithms such as ciphers (AES, Blowfish, DES, IDEA etc.), and cryptographic hash functions (MD5, MD4, SHA-1, SHA-2 etc.)
In this guide, we are going to install the latest version of OpenSSL on CentOS 7.
Deploying your cloud server
If you have not already registered with Cloudwafer, you should begin by getting signed up. Take a moment to create an account after which you can easily deploy your own cloud servers.
Once you have signed up, log into your Cloudwafer Client Area with the password provided in your mail and deploy your Cloudwafer cloud server.
Updating System Packages on CentOS
It is always recommended that you update the system to the latest packages before beginning any major installations. This is done with the command below:
Before we begin our installation, you can check the version of OpenSSL installed on your server by issuing the command below:
Step 1: Install Development Tools
The 'Development tools' are a yum group, which is a predefined bundle of software that can be installed at once, instead of having to install each application separately. The Development tools will allow you to build and compile software from source code. Issue the command below to install:
Issue the following command below to install other necessary packages and libraries.
Step 2: Download OpenSSL
Next, we are going to download OpenSSL from the source (getting the latest version which at the time of writing this guide, the latest stable version is the 1.1.1 series).
Next, extract the downloaded file using the command below:
Next, navigate to the extracted directory.
Step 3: Install OpenSSL
We are now going to install the latest version of OpenSSL which we downloaded using the command below:
Step 4: Configure OpenSSL Shared Libraries
Naviagate to the /etc/ld.so.conf.d directory and create a new configuration file 'openssl-1.1.1c.conf'.
Enter the following:
Ensure to save before you exit.
Next, reload the dynamic link by issuing the command below:
Install Openssl Php Extension Centos Server Free
Step 5: Configure OpenSSL Binary
In our final configuration, we are going to insert the binary of our new version of OpenSSL installed (located at /usr/local/ssl/bin/openssl) to replace the default openssl binary (located at /usr/bin/openssl or /bin/openssl).
First, backup the default OpenSSL binary files.
Next, create new environment files for OpenSSL:
Enter the following:
Install Openssl Php Extension Centos Server For Windows 10
Ensure to save before you exit.
Install Openssl Php Extension Centos Server 2017
Next, make the openssl.sh file executable by issuing the command below:
Next, reload the OpenSSL environment and check the PATH bin directory using commands below:
Install Openssl Php Extension Centos Servers
We can now check and verify our installation of the latest stable version of OpenSSL using the command below:
