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.<\/p>\n\n\n\n
After installing the Ubuntu 14.04 server version (32 or 64 bit version), install the following packages<\/p>\n\n\n\n
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 <\/code><\/pre>\n\n\n\nDownload the latest version of php5.3<\/a>, decompress and configure.<\/p>\n\n\n\n.\/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-dir<\/code><\/pre>\n\n\n\nIn caso di versione dell\u2019os a 64 bit modificare il parametro \u2013with-libdir=lib\/x86_64-linux-gnu .<\/p>\n\n\n\n
Aggiungere alla riga che inizia per \u201cEXTRA_LIBS\u201d il valore \u201c-lstdc++\u201d (si pu\u00f2 mettere come primo parametro). Senza questo valore da questo errore durante la compilazione:<\/p>\n\n\n\n
error adding symbols: DSO missing from command line<\/p>\n\n\n\n
Questa \u00e8 la riga dopo la modifica<\/p>\n\n\n\n
EXTRA_LIBS = -lstdc++ -lcrypt -lz -lexslt -ltidy -lresolv -lcrypt -lrt -lmysqlclient …<\/p>\n\n\n\n
Infine procedere con la compilazione e l\u2019installazione.<\/p>\n\n\n\n
make\nmake test\nmake install<\/code><\/pre>\n\n\n\nCopiare il file php.ini di produzione nella directory corretta e fare le modifiche necessarie.<\/p>\n\n\n\n
cp \/opt\/php-source\/php-5.3.29\/php.ini-production \/usr\/local\/lib\/php.ini<\/code><\/pre>\n\n\n\nDurante l\u2019installazione 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<\/p>\n\n\n\n
AddType application\/x-httpd-php .php\nAddType application\/x-httpd-php-source .php<\/code><\/pre>\n\n\n\nDisattivare e riattivare il modulo php e riavviare apache.<\/p>\n\n\n\n
