prefix) such as /usr/local/php5 will probably do. In this instance, we are using a path including the minor version for A to B and regression testing. With OpenSSLv1 in place under /usr/local/opensslv1/, we need to compile PHP5 to use this binary and its libraries:įirst, install the required libraries to resolve dependencies:Īpt-get install libfcgi-dev libfcgi0ldbl libjpeg-turbo8-dbg libmcrypt-dev libssl-dev libc-client2007e libc-client2007e-dev libxml2-dev libbz2-dev libcurl4-openssl-dev libjpeg-dev libpng-dev libfreetype6-dev libkrb5-dev libpq-dev libxml2-dev libxslt1-dev For example, I initially used OpenSSL 1.0.0 which is a contemporary of PHP5.6.2 for troubleshooting and installed version 1.0.2 over it. We can upgrade binaries in-place by choosing the same exact prefix in a new build: Extract a newer source code archive inside the build directory side-by-side with the older one and re-run the config, compile and install.

Then, run make, install and test the binary: There already is a Makefile in the folder, however we need to change the install path:

Therefore we need OpenSSL version 1.0, which can also be installed under /usr/local/Īgain, create the build folder and get your source code: PHP5 requires OpenSSL v1 to compile – the system comes with OpenSSL 1.1.1 which will cause errors when compiling PHP5. I like to use /usr/local for this, other ISPConfig tutorials use /optįirst, create the build folder and get the source: Installing an older version of a binary that comes with an operating system requires installing it under an alternate path, alongside all its libraries and configuration files. The web hosting management app ISPConfig makes it easy to switch back and forth between versions of PHP – except the Apache module cannot be swapped out, therefore we are limited to using the actual PHP binary through the FastCGI and FastCGI Process Manager (FPM). Some web site code written in the PHP 5 (or earlier) era is not compatible with that version of the hypertext preprocessor and will break under a new OS build with all up-to-date binaries. This article describes the process of installing PHP5.6 on Ubuntu Linux 20.04 LTS as an additional PHP version.
