install alternate PHP version along with current version

Requirement: The client is hosted on a server with php 5.3 and he want to enable  5.4 for his domain. To this, we are installing php 5.4 to another location in  the same server.

1. cd /usr/src

2. Download PHP version from http://in3.php.net/get/php-5.4.28.tar.gz/from/a/mirror using wget

3. tar -xzvf php-5.4.28.tar.gz

4. cd php-5.4.28

5. Make sure the installation path --prefix is specified and is compiled as cgi using the option --enable-cgi. In this case I am using the installation path as --prefix=/usr/local/php54

Make sure to remove the configuration parameter for apxs  ie   --with-apxs2=/usr/local/apache/bin/apxs

./configure  --disable-fileinfo --disable-phar --enable-bcmath --enable-calendar --enable-libxml --enable-mbstring --enable-pdo=shared --enable-soap --enable-sockets --enable-wddx --enable-zend-multibyte --enable-zip --prefix=/usr/local/php54 --enable-cgi --with-bz2 --with-curl=/opt/curlssl/ --with-curlwrappers --with-freetype-dir=/usr --with-gd --with-gettext --with-imap=/opt/php_with_imap_client/ --with-imap-ssl=/usr --with-jpeg-dir=/usr --with-kerberos --with-libdir=lib64 --with-libexpat-dir=/usr --with-libxml-dir=/opt/xml2/ --with-mcrypt=/opt/libmcrypt/ --with-mm=/opt/mm/ --with-mysql=/usr --with-mysql-sock=/var/lib/mysql/mysql.sock --with-mysqli=/usr/bin/mysql_config --with-openssl=/usr --with-openssl-dir=/usr --with-pcre-regex=/opt/pcre --with-pdo-mysql=shared --with-pdo-sqlite=shared --with-pic --with-png-dir=/usr --with-pspell --with-tidy=/opt/tidy/ --with-xmlrpc --with-xpm-dir=/usr --with-xsl=/opt/xslt/ --with-zlib --with-zlib-dir=/usr

6. make

7. make install

Now, check if binary is installed:

===
/usr/local/php5/bin/php-cgi -v
===

It should show as cgi.

Now add the following lines on top of the httpd.conf file
===
ScriptAlias /php54/ /usr/local/php54/bin/
Action application/x-httpd-php54 /php54/php-cgi
<Directory “/usr/local/php54/bin/”>
Allow from all
</Directory>
===

Save httpd.conf file and restart apache.

Open a .htaccess file inside the folder where you need php5 and add the following code to it. Make sure .htaccess support is enabled in your apache configuration.

===

AddHandler application/x-httpd-php54 .php
===

Make a phpinfo.php file in this directory and see what is shows when taken in browser. It should be php5.4

Joomla login not accepting

Issue: joomla not accepting the logins we are providing. It just refresh the page when we click login button after enter the login credential, and stay on the same login page. 

Possible fixes:

1. Give 777 permission for the directory specified for 'session.save_path' in the php.ini file.

2. Try changing the  'session.save_path' in the php.ini file and give 777 permission to it.

3. Another work around is change "var $session_handler = 'database';" to var $session_handler = 'None';  OR vice versa in configuration.php file.
