Tips on how to Use PHP 4.4.9 (FastCGI) With Apache & ISPConfig 3 (Debian Wheezy)

Since ISPConfig 3.0.5, it is possible to use multiple PHP versions on one server and select the optimal PHP version for a website. If you have some very old websites on your server, they might not work with PHP5, but only with PHP4. This tutorial shows how to build PHP 4.4.9 as a FastCGI version for use with Apache2 on a Debian Wheezy server. This PHP version can be used together with the default PHP (installed through apt) in ISPConfig.

I do not issue any guarantee that this will work for you!

1 Preliminary Note

PHP-FPM is not available for PHP4, therefore I just describe how to build a FastCGI version of PHP4. FastCGI is available only for Apache servers, therefore you cannot use it with nginx..

2 Building PHP 4.4.9 (FastCGI)

Install the prerequisites for building from source code:

apt-get install build-essential

PHP 4.4.9 will not compile with modern OpenSSL versions, therefore we need to install an older OpenSSL version (0.9.8x) first:

cd /tmp wget http://www.openssl.org/source/openssl-0.9.8x.tar.gz tar xvfz openssl-0.9.8x.tar.gz cd openssl-0.9.8x ./config –prefix=/usr/local/openssl-0.9.8 make make install

Download and extract PHP 4.4.9:

mkdir /opt/phpfcgi-4.4.9 mkdir /usr/local/src/php4-build cd /usr/local/src/php4-build wget http://de.php.net/get/php-4.4.9.tar.bz2/from/this/mirror -O php-4.4.9.tar.bz2 tar jxf php-4.4.9.tar.bz2

cd php-4.4.9/

Create some necessary symlinks:

ln -s /usr/lib/x86_64-linux-gnu/libjpeg.so /usr/lib/ ln -s /usr/lib/x86_64-linux-gnu/libpng.so /usr/lib/ ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so.18 /usr/lib/ ln -s /usr/lib/x86_64-linux-gnu/libexpat.so /usr/lib/ ln -s /usr/lib/x86_64-linux-gnu/libmysqlclient.so /usr/lib/libmysqlclient.so mkdir /usr/kerberos ln -s /usr/lib/x86_64-linux-gnu /usr/kerberos/lib

Next we must disable the functions mysql_drop_db and mysql_create_db because otherwise you will get these errors when you try to build PHP 4.4.9:

error: undefined reference to ‘mysql_drop_db’ error: undefined reference to ‘mysql_create_db’

Open /usr/local/src/php4-build/php-4.4.9/ext/mysql/php_mysql.c…

vi /usr/local/src/php4-build/php-4.4.9/ext/mysql/php_mysql.c

… and go to line 1131. From there on, comment out both functions:

[...] /*PHP_FUNCTION(mysql_create_db) { zval **db, **mysql_link; int id; php_mysql_conn *mysql; switch(ZEND_NUM_ARGS()) { case 1: if (zend_get_parameters_ex(1, &db)==FAILURE) { RETURN_FALSE; } id = php_mysql_get_default_link(INTERNAL_FUNCTION_PARAM_PASSTHRU); CHECK_LINK(id); break; case 2: if (zend_get_parameters_ex(2, &db, &mysql_link)==FAILURE) { RETURN_FALSE; } id = -1; break; default: WRONG_PARAM_COUNT; break; } php_error_docref(NULL TSRMLS_CC, E_NOTICE, "This function is deprecated, please use mysql_query() to issue a SQL CREATE DATABASE statement instead."); ZEND_FETCH_RESOURCE2(mysql, php_mysql_conn *, mysql_link, id, "MySQL-Link", le_link, le_plink); PHPMY_UNBUFFERED_QUERY_CHECK(); convert_to_string_ex(db); if (mysql_create_db(&mysql->conn, Z_STRVAL_PP(db))==0) { RETURN_TRUE; } else { RETURN_FALSE; } }*/ /* }}} */ /* {{{ proto bool mysql_drop_db(string database_name [, int link_identifier]) Drops (delete) a MySQL database */ /*PHP_FUNCTION(mysql_drop_db) { zval **db, **mysql_link; int id; php_mysql_conn *mysql; switch(ZEND_NUM_ARGS()) { case 1: if (zend_get_parameters_ex(1, &db)==FAILURE) { RETURN_FALSE; } id = php_mysql_get_default_link(INTERNAL_FUNCTION_PARAM_PASSTHRU); CHECK_LINK(id); break; case 2: if (zend_get_parameters_ex(2, &db, &mysql_link)==FAILURE) { RETURN_FALSE; } id = -1; break; default: WRONG_PARAM_COUNT; break; } php_error_docref(NULL TSRMLS_CC, E_NOTICE, "This function is deprecated, please use mysql_query() to issue a SQL DROP DATABASE statement instead."); ZEND_FETCH_RESOURCE2(mysql, php_mysql_conn *, mysql_link, id, "MySQL-Link", le_link, le_plink); convert_to_string_ex(db); if (mysql_drop_db(&mysql->conn, Z_STRVAL_PP(db))==0) { RETURN_TRUE; } else { RETURN_FALSE; } }*/ /* }}} */ [...]

Install the prerequisites for building PHP5 (in our case this also covers the prerequisites for building PHP4):

apt-get build-dep php5

Configure and build PHP 4.4.9 as follows (you can adjust the ./configure command to your needs, take a look at

./configure –help

to see all available options; if you use a different ./configure command, it is possible that additional libraries are required, or the build process will fail):

./configure \ –prefix=/opt/phpfcgi-4.4.9 \ –with-pdo-pgsql \ –with-zlib-dir \ –with-freetype-dir \ –enable-mbstring \ –with-libxml-dir=/usr \ –enable-soap \ –enable-calendar \ –with-curl \ –with-mcrypt \ –with-zlib \ –with-gd \ –with-pgsql \ –disable-rpath \ –enable-inline-optimization \ –with-bz2 \ –with-zlib \ –enable-sockets \ –enable-sysvsem \ –enable-sysvshm \ –enable-pcntl \ –enable-mbregex \ –with-mhash \ –enable-zip \ –with-pcre-regex \ –with-mysql=/usr \ –with-mysql-sock=/var/run/mysqld/mysqld.sock \ –with-jpeg-dir=/usr \ –with-png-dir=/usr \ –enable-gd-native-ttf \ –with-openssl=/usr/local/openssl-0.9.8 \ –with-openssl-dir=/usr/local/openssl-0.9.8 \ –with-libdir=/lib/x86_64-linux-gnu \ –enable-ftp \ –with-imap \ –with-imap-ssl \ –with-kerberos \ –with-gettext \ –with-expat-dir=/usr \ –enable-fastcgi

The last switch (–enable-fastcgi) makes sure this PHP version will work with FastCGI.

make make install

Copy php.ini to the correct location:

cp /usr/local/src/php4-build/php-4.4.9/php.ini-recommended /opt/phpfcgi-4.4.9/lib/php.ini

That’s it – we will now add the APC module to our PHP 4.4.9 installation:

cd /tmp wget http://pecl.php.net/get/APC-3.0.19.tgz tar xvfz APC-3.0.19.tgz cd APC-3.0.19 /opt/phpfcgi-4.4.9/bin/phpize ./configure –enable-apc –enable-apc-mmap –with-php-config=/opt/phpfcgi-4.4.9/bin/php-config make make install

Afterwards, open /opt/phpfcgi-4.4.9/lib/php.ini…

vi /opt/phpfcgi-4.4.9/lib/php.ini

… and set extension_dir = “/opt/phpfcgi-4.4.9/lib/php/extensions/no-debug-non-zts-20020429″ and add the line extension=apc.so at the end of the file (you can also configure some additional APC settings):

[...] extension_dir = "/opt/phpfcgi-4.4.9/lib/php/extensions/no-debug-non-zts-20020429" [...] extension=apc.so apc.enabled=1 apc.shm_segments=1 apc.shm_size=512 apc.ttl=0 apc.user_ttl=600 apc.gc_ttl=600 apc.enable_cli=1 apc.mmap_file_mask=/tmp/apc.XXXXXX ;apc.mmap_file_mask=/dev/zero ;apc.shm_segments = 5

In ISPConfig 3.0.5, you can configure the new PHP version under System > Additional PHP Versions. On the Name tab, you just fill in a name for the PHP version (e.g. PHP 4.4.9) – this PHP version will be listed under this name in the website settings in ISPConfig:

Go to the FastCGI Settings tab (the PHP-FPM Settings tab can be left empty) and fill out the fields as follows:

If everything is working as expected, you can now choose PHP 4.4.9 for a website in ISPConfig. You can check the PHP version of a website by creating a PHP file with the phpinfo(); function in it and calling that file in your browser:
