1. If you found sometimes you cannot see any data from server and you see the log below:
[Thu Jul 18 18:08:30 2013] [notice] child pid 24544 exit signal Segmentation fault (11)
That means your apache and php doesn’t work well together, you need to try to make another installation
2. If you find you cannot start apache with php, get alert like this:
httpd: Syntax error on line 53 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server: ld.so.1: httpd: fatal: relocation error: file /usr/local/apache2/modules/libphp5.so: symbol sapi_module: referenced symbol not found
Maybe you can install a lower version of php and apache to fix it.
