Hi there,
The reason for this issue is that your PHP/nginx/Varnish settings are not configured properly to run the Magento installation process.
The installation process requires the following settings:
All web servers and Varnish
- Locate your php.ini using a phpinfo.php file.
- As a user with root privileges, open php.ini in a text editor.
- Locate the max_execution_time setting.
- Change its value to 18000.
- Save your changes to php.ini and exit the text editor.
Restart Apache:
- CentOS: service httpd restart
- Ubuntu: service apache2 restart
If you use nginx or Varnish, continue with the following sections.
nginx only
If you use nginx, use our included nginx.conf.sample or add a timeout settings in the nginx host configuration file to the location ~ ^/setup/index.php section as follows:
location ~ ^/setup/index.php {
..................... fastcgi_read_timeout 600s; fastcgi_connect_timeout 600s;
}Restart nginx: service nginx restart
Varnish only
If you use Varnish, edit default.vcl and add a timeout limit value to the backend stanza as follows:
backend default {
.....................
.first_byte_timeout = 600s;
}Restart Varnish.
service varnish restart
