How to solve proxy_fcgi:error AH01071: Got error 'Unable to open primary script

 Hello,

Recently I got stuck with strange bug on centOS server. After I updated document root for my primary domain which has Laravel App installed. 

When we try to access app through domain, we got following error. 

No input file specified.

I initially thought it's the permission issue on .htaccess issue. Tried changing permissions and adding some rewrite rules but it didn't work. When I checked apache error logs. I got following error. 

proxy_fcgi:error AH01071: Got error 'Unable to open primary script

I had no idea how to solve this error. So tried few things like

• Restart apache
• Restart php-fpm
• Restart VPS
• Removed and added account few times.
• Disabling php-fpm

But nothing worked. I spent almost entire night in solving this issue but no luck. But finally I was able to solve the issue by following steps. It was actually the issue with php fpm, as it was not able to find out root folder for the domain. So here is what you have to do. 

First go to userdata directory 

/var/cpanel/userdata/<USERNAME>

Here you will find one file. 

yourdomain.com.php-fpm.yaml

Open this file with nano or vim editor and add following line at the end of it. 

php_admin_value_doc_root: { name: 'php_admin_value[doc_root]', value: /home/<USERNAME>/public_html/<DOCUMENT_ROOT> }

Save the file and then execute following commands one by one.

/scripts/php_fpm_config --rebuild 

/scripts/restartsrv_apache_php_fpm 

/scripts/restartsrv_httpd

This will rebuild php fpm config and restart php fpm service for apache. Now in the same folder open 

YOURDOMAIN.com 

YOURDOMAIN.com_SSL

Change document root here as well and run following commands.

/scripts/rebuildhttpdconf 

/scripts/restartsrv_httpd

This will rebuild apache config file and restart apache. 

This is it and now if you visit your domain, you will not have the issue of file missing. 

Hope this saves your time

.htaccess

Hello,

Recently I configured SSL on Amazon EC2 instance running Apache server. In this blog I am going to explain the procedure step by step.

Step 1 : Generate CSR and submit to CA authority for verification

To generate CSR login to your server with SSH and use following command.

openssl req -new -newkey rsa:2048 -nodes -keyout YourDomain.key -out YourDomain.csr

Once you execute this command it will ask for certain inputs and based on it it will generate csr file. That you have to submit to CA authority and generate

Step 2 : Edit Inbound rules on your EC2 Instance and allow HTTPS

Login to Amazon AWS console and go to EC2 dashboard. Click on instance and edit security rules. Select HTTPs and allow it from anywhere.

Step 3 : Upload your SSL certificate and key file to EC2 using SSH

 You can use SCP command to upload crt file and pem key file to server.

scp -i "YourKey.pem" "Cert.crt" ubuntu@YourIP:/home/ubuntu/Cert.crt
scp -i "YourKey.pem" "Key.key" ubuntu@YourIP:/home/ubuntu/Key.key

Step 4 : Edit Default SSL config file and Add Certificate In File

Go to  cd /etc/apache2/sites-available

Update default-ssl.conf file by using command

sudo nano default-ssl.conf

Add following lines in file

SSLEngine on
SSLCertificateFile      /home/ubuntu/Cert.crt
SSLCertificateKeyFile /home/ubuntu/Key.key

Save the file.

Step 5 : Enable SSL mode in Apache and set config file to default-ssl.conf

Now we have ssl config file set, we have to enable SSL mode in apache and set config file.

Use following command

sudo a2enmod ssl
sudo a2ensite default-ssl.conf
sudo service apache2 reload
sudo service apache2 restart

That's it and now you can access your web app on HTTPS. Hope this helps you.

.htaccess Doesn't Work in Amazon AWS EC2 Instance with Ubuntu

Recently I was configuring Laravel application in Amazon AWS EC2 instance which was having Ubuntu and Apache installed. The problem was htacess file was not working so Laravel routes were not working. Instead of parsing laravel routes it always shows error URL not found.

The problem is by default in apache installed on ubuntu doesn't have .htaccess enabled so first you have to manually enable it in config file and restart apache.

Here are the steps.

1) Login to your EC2 instance with SSH.

ssh -i "Yourkey.pem" ubuntu@yourpublicip

2) Enable Mode Rewrite, this is just incase if it's not enabled.

sudo a2enmod rewrite

3) Go to following directory.

cd /etc/apache2/sites-available

If you use LS command here you will see following file.

000-default.conf

That's the file with default apache configuration which are applied to your sites in /var/www/html folder.

4) Open this file for editing.

sudo nano 000-default.conf

5) Add following lines after DocumentRoot /var/www/html line.

<Directory />
     Options FollowSymLinks
     AllowOverride All
</Directory>
<Directory /var/www/html>
     Options Indexes FollowSymLinks MultiViews
     AllowOverride All
     Order allow,deny
     allow from all
</Directory>

6) Save the file and restart the apache.

sudo service apache2 restart

that's it and now your .htaccess file will work and your laravel application will start working.
