knowledgebase/linux/webserver/apache/php 1 Compiling PHP mcrypt extension Note: These instructions are for RHEL4-based distributions. You'll need the PHP 'devel' package, g++ and libtool to build mcrypt {code:none} apt-get install php-devel autoconf cpp gcc-c++ libtool {code} Grab it and install it {code:none} function installmcrypt() { wget "http://easynews.dl.sourceforge.net/sourceforge/mcrypt/libmcrypt-2.5.7.tar.gz" if [ $? -ne 0 ]; then return 1; fi tar xzf libmcrypt-2.5.7.tar.gz if [ $? -ne 0 ]; then return 1; fi cd libmcrypt-2.5.7 if [ $? -ne 0 ]; then return 1; fi ./configure --disable-posix-threads if [ $? -ne 0 ]; then return 1; fi replace "CFLAGS = -g -O2" "CFLAGS = -g -O2 --disable-posix-threads" -- Makefile if [ $? -ne 0 ]; then return 1; fi make && make install if [ $? -ne 0 ]; then return 1; fi } installmcrypt {code} Now grab the PHP source and build the extension. You'll need the source tarball matching your distributions PHP version (4.3.7 for RHEL4). {code:none} function phpizemcrypt() { wget "http://www.php.net/get/php-4.3.9.tar.gz/from/www.php.net/mirror" if [ $? -ne 0 ]; then wget "http://museum.php.net/php4/php-4.3.9.tar.gz" if [ $? -ne 0 ]; then return 1; fi fi tar xvzf php-4.3.9.tar.gz if [ $? -ne 0 ]; then return 1; fi cd php-4.3.9/ext/mcrypt if [ $? -ne 0 ]; then return 1; fi phpize if [ $? -ne 0 ]; then return 1; fi ./configure if [ $? -ne 0 ]; then return 1; fi make && make install if [ $? -ne 0 ]; then return 1; fi } phpizemcrypt {code} phpize failing? Try an older version of automake and then re-run phpize, configure, make, make install. {code:none} { apt-get install automake-1.7 mv /usr/bin/aclocal /usr/bin/aclocal.old ln -s /usr/bin/aclocal-1.7 /usr/bin/aclocal } {code} Finally, setup the extension in your php.ini or /etc/php.d if RHEL4-based, and restart Apache: {code:none} { echo "extension=mcrypt.so" > /etc/php.d/mcrypt.ini /etc/init.d/httpd restart } {code} Check to see that mcrypt shows up in a test phpinfo() page. Other extensions can be built in a similar way (i.e. make sure you have the dependancies, grab the PHP tarball, and use phpize, configure, make, make install). 1 Testing php send mail capabilities From: http://www.webcheatsheet.com/php/send_email_text_html_attachment.php Edit and save the following file in a externally accessible directory from your web server (usually /var/www/html or /var/www): http://bliki.rimuhosting.com/space/knowledgebase/linux/webserver/apache/php/mailtest.php Then if you saved it as test.php, go to http://207.210.242.17/test.php and see if you got the e-mail. If you didn't check the mail logs (/var/log/maillog or /var/log/mail.log) to see what happened. 1 Enabling an upload directory for PHP scripts in Debian The default php.ini file lacks the configuration directive for upload_tmp_dir, which is needed for file uploads. That is default on Debian for security purposes. In order to use an upload directory, set the upload_tmp_dir parameter in php.ini to a directory that can be read and modified by the HTTP server user. 2008-02-14 12:00:10.0 2005-08-26 00:18:46.0 Wed May 30 16:09:35 EDT 2007
