.htaccess Rewriting CodeIgniter URLs on Apache 2.4 and mod_fastcgi_handler (FCGI)

.htaccess Rewriting CodeIgniter URLs on Apache 2.4 and mod_fastcgi_handler (FCGI)

CodeIgniter had some problems with mod_rewrite on a shared hosting account where the hoster runs
Apache + FCGI
When you tried to use CI’s SEO URLs, you'll get an error 'No input file specified'.

And the solution here:
Create an .htaccess file in the same directory with index.php and paste into it:

RewriteEngine On
# Existing files and directories remain accessible
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.* - [L]

# Redirect the rest
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php?/$1 [QSA,L]

Other solution :
Create a customized PHP.INI file under the root directory of your site with the following line.

cgi.fix_pathinfo = 0;

PHP FCGI

A default installation of FastCGI on cPanel server is dangerously simple. It’s dangerous because one cPanel account (or one vhost) is capable of crashing down a whole server if, say, traffic were to spike up. It’s also simple because it won’t allow complex scripts to run cleanly. In brief, it’s absolutely not ready for production as-is. In this post, I’ll go over what it takes to configure FastCGI on a cPanel node properly.

The following is a list of settings that you need to add to /etc/httpd/conf/php.conf upon switching to FastCGI:

MaxRequestsPerProcess 1000
FcgidMaxProcesses 200
FcgidProcessLifeTime 7200
MaxProcessCount 500
FcgidIOTimeout 400
FcgidIdleTimeout 600
FcgidIdleScanInterval 90
FcgidBusyTimeout 300
FcgidBusyScanInterval 80
ErrorScanInterval 3
ZombieScanInterval 3
DefaultMinClassProcessCount 0
DefaultMaxClassProcessCount 3
MaxRequestLen 20468982

You’re more likely to adjust the settings in bold above. DefaultMinClassProcessCount 0 instructs FastCGI to keep zero PHP processes running for user when traffic is idle (cPanel account user) . On the other hand, DefaultMaxClassProcessCount 3 tells FastCGI to never allow more than 3 PHP processes running at a time. This settings prevents one users from crashing the server were they to receive a lot of traffic.

So go ahead and copy/paste the above into your httpd.conf and restart Apache (service httpd restart). You’re good to go now!

Distill and rebuild Apache, then restart Apache

root@server[#] /usr/local/cpanel/bin/apache_conf_distiller --update
root@server[#] /scripts/rebuildhttpdconf
root@server[#] /etc/init.d/httpd restart

/etc/httpd/conf/php.conf

# Fastcgi configuration for PHP5
LoadModule fcgid_module modules/mod_fcgid.so
MaxRequestsPerProcess 500
DefaultMinClassProcessCount 0
DefaultMaxClassProcessCount 2
MaxRequestLen 204689820
FcgidConnectTimeout 150
FcgidIdleScanInterval 90
FcgidIOTimeout 150
AddHandler fcgid-script .php5 .php4 .php .php3 .php2 .phtml

How to enable Custom php.ini for PHP FCGI

If you want to enable custom php.ini settings for PHP FCGI on your server then follow the below steps : 

1 > Create a .htaccess file under the directory : /home/username/public_html
root@server[#] cd /home/username/public_html
root@server[/home/username/public_html]# vi .htaccess
And the below two lines at the top :
AddHandler php5-fastcgi .php
Action php5-fastcgi /cgi-bin/php.fcgi
save and quit.

2 > go to the cgi-bin directory : /home/username/public_html/cgi-bin
root@server[#] cd /home/username/public-html/cgi-bin
and then copy the default php.ini here
root@server[#] cp /usr/local/lib/php.ini /home/username/public_html/cgi-bin/

3 > Create php.fcgi file to load custom php.ini
Please note that you should still be in /home/username/public_html/cgi-bin location.
root@server[/home/username/public_html/cgi-bin] # vi php.fcgi
and then add the below code :
#!/bin/sh
export PHP_FCGI_CHILDREN=1
export PHP_FCGI_MAX_REQUESTS=10
exec /usr/local/cpanel/cgi-sys/php5
save and quit.
Now make the file php.cgi executable:
root@server[/home/username/public_html/cgi-bin] # chmod + x php.fcgi

4 > Change ownership of files to correct user:
root@server[/home/username/public_html/cgi-bin] chown username.username * -R

And if it still does not work for you then follow the below steps as well :

5 > Add paths to php.conf file
root@server[#] vi /usr/local/apache/conf/php.conf
and add the below lines :
Action php5-fastcgi /cgi-bin/php.fcgi
AddType application/x-httpd-php .php
save and quit.
and after adding the above two lines the php.conf file should look like this :
root@server[/usr/local/apache/conf] # cat php.conf
# Fastcgi configuration for PHP5
LoadModule fcgid_module modules/mod_fcgid.so
MaxRequestsPerProcess 500
AddHandler fcgid-script .php5 .php4 .php .php3 .php2 .phtml
Action php5-fastcgi /cgi-bin/php.fcgi
AddType application/x-httpd-php .php
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php5
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php4
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php3
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .php2
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .phtml
# End of autogenerated PHP configuration.

6 > Distill and rebuild Apache, then restart Apache
root@server[#] /usr/local/cpanel/bin/apache_conf_distiller –update
root@server[#] /scripts/rebuildhttpdconf
root@server[#] /etc/init.d/httpd restart

And finally to test if the custom php.ini is working follow the steps :

root@server[#] cd /home/username/public_html
root@server[/home/username/public_html]# vi info.php
Add the below lines :
< ?php
phpinfo();
?>
save and quit.
Change the ownership of info.php file to user:user
root@server[/home/username/public_html]# chown username:username info.php
Now browse the URL : http://domain.com/info.php
And search for the line : Loaded Configuration File
Loaded Configuration File /home/username/public_html/cgi-bin/php.ini

Or
Here's a simpler solution:

Edit the file called /usr/local/cpanel/cgi-sys/php5 -- insert the line above exec /usr/bin/php as follows:

Code:

#!/bin/sh

# If you customize the contents of this wrapper script, place
# a copy at /var/cpanel/conf/apache/wrappers/php5
# so that it will be reinstalled when Apache is updated or the
# PHP handler configuration is changed

[ -f ~/php.ini ] && exec /usr/bin/php -c ~/
exec /usr/bin/php 

Copy the file over to /var/cpanel/conf/apache/wrappers/php5 as indicated at the top of the file.

Now, if any account has a php.ini file in their home directory (not public_html) then it will be used instead of the system-provided one.
