thanks falko. all running smoothly.
but there is one that makes me confused. if I commented out the "#LoadModule php5_module modules/libphp5.so" in "/etc/httpd/conf.d/php.conf", then when I tried to restart httpd service, the error message would appear like this:
Starting httpd: Syntax error on line 50 of /etc/httpd/conf/vhosts/Vhosts_ispconfig.conf:
Invalid command 'php_admin_flag', perhaps misspelled or defined by a module not included in the server configuration
but if I did not comment out "LoadModule php5_module modules/libphp5.so", all running smoothly. Do you know the problem?
