One of the difficulties I encountered during my work is to enable the https/tls 1.2 protocol for old applications developed with PHP 4.4. The most obvious thing would be to update/redo the application with a newer version of PHP, for example 5.6 or better still with a 7.4 or 8.0. However, it is not always possible, either because the customer cannot afford to spend to update it, or because it is an application that interacts with Legacy systems, or because a version of the same is already in progress but for the moment that old must continue to work.
After installing the Ubuntu 14.04 server version (32 or 64 bit version), install the following packages
apt-get install build-essential libxml2-dev apache2 apache2-dev libssl-dev libsslcommon2-dev libbz2-dev libcurl4-gnutls-dev libpng12-dev libgmp-dev libmcrypt-dev libtidy-dev libxslt1-dev libltdl-dev libjpeg-dev libgif-dev libmysqlclient-dev libmysqlclient18 icu-devtools libicu-dev Download the latest version of php5.3, decompress and configure.
./configure --with-libdir=lib/i386-linux-gnu --with-apxs2 --with-openssl --with-pcre-regex --with-zlib --enable-bcmath --with-bz2 --enable-calendar --with-curl --enable-exif --enable-ftp --with-gd --enable-gd-native-ttf --with-gettext --with-gmp --with-mhash --enable-intl --enable-mbstring --with-mcrypt --with-mysql --with-mysql-sock --with-mysqli --enable-pcntl --with-pdo-mysql --enable-sockets --with-tidy --enable-wddx --with-xmlrpc --with-xsl --enable-zip --with-png-dir --with-jpeg-dirIn caso di versione dell’os a 64 bit modificare il parametro –with-libdir=lib/x86_64-linux-gnu .
Aggiungere alla riga che inizia per “EXTRA_LIBS” il valore “-lstdc++” (si può mettere come primo parametro). Senza questo valore da questo errore durante la compilazione:
error adding symbols: DSO missing from command line
Questa è la riga dopo la modifica
EXTRA_LIBS = -lstdc++ -lcrypt -lz -lexslt -ltidy -lresolv -lcrypt -lrt -lmysqlclient …
Infine procedere con la compilazione e l’installazione.
make
make test
make installCopiare il file php.ini di produzione nella directory corretta e fare le modifiche necessarie.
cp /opt/php-source/php-5.3.29/php.ini-production /usr/local/lib/php.iniDurante l’installazione non viene creato il file di configurazione che aggiunge il tipo .php ad Apache. Creare quindi il file /etc/apache2/mods-available/php5.conf con il seguente contenuto
AddType application/x-httpd-php .php
