Php – Allow outgoing connections for cURL on LAMP stack

curllampPHP

I've been trying to setup a LAMP stack to use as a web development server and it's proving to be very frustrating for a novice like myself.

On a Fedora 16 machine, I've got Apache, MySQL, PHP, cURL, & Bind DNS installed and configured (though probably not quite correctly.) I've managed to get my CMS installed and working for a test site. That tells me Apache, PHP, & MySQL are working correctly.

However I'm running into a problem where the CMS used cURL to access an update server to do automatic updates as well as some other things (auto-installing add-ons.) WHen I try to enable this, I get an error that tells me to check that my server is running cURL (phpinfo tells me it is) and that allow_url_fopen is set to "On" (also true) and otherwise check with my web host to make sure outgoing connections for cURL are allowed.

Since I am the web host, I cannot seem to find the port I need to open up or settings I need to adjust to allow outgoing connections or even how to check what the current settings are. How do I check/allow outgoing connections for cURL?

Assuming you can SSH into your development machine, try to e.g. telnet to the update host, or to www.google.com port 80.

telnet www.google.com 80

If that works, you will at least know you have access to the outside world. cURL then should have access to the outside world as well. Are you perhaps using a proxy to reach the internet? In that case, you will have to tell cURL about the proxy host and port. Are you doing any local firewalling on the development machine? Then make sure you allow outgoing traffic.

Linux – In Ubuntu I make changes to php.ini but nothing happens

I've had the same problem with an earlier version of Ubuntu (12.04), Apache 2.2.22 and php5-fpm fastCGI flavour of PHP. Doing

service apache2 restart

isn't enough, because it just restarts the http server: you have to issue also the command

service php5-fpm restart

to have the application server restarted and PHP read the php.ini file again.

Since you're getting the error Fatal error: Call to undefined function mysql_connect(), that means that the MySQL extension is not being loaded by PHP. This is configured in your php.ini file.

To find the location of your php.ini file, create a php file and in it paste the following.
<?php phpinfo(); ?>

On the page (near the top) you will have an entry labelled Loaded Configuration File. Check this file that has been loaded is actually the one that you expect it to load. Personally, mine loads from C:/php/php.ini, but if I recall correctly when I was initially setting it all up, it was trying to read from C:/Windows/php.ini (which didn't exist) so was using defaults for everything, which didn't include some of the extra modules I wanted.

Open that file with your favourite text editor and in there should be several lines beginning extension=xxxxx.dll.

Look through the list of modules and check that extension=php_mysql.dll is listed and the first character of the line is not a semi-colon (;). If it's not listed, just add it to the list - if it has the semi-colon at the beginning of the line, remove the semi-colon and save the file.

You should also check the value of extension_dir, and also verify this path exists on the filesystem. This should be something similar to c:/php/ext.

Once you've made changes to the php.ini file, you will need to restart Apache so the configuration file is re-read.

Once you've restarted Apache, refresh your phpinfo page and check that it has sections listed for MySQL.

You might also want to check if C:\php is included in your PATH environment variable.

If you're still having issues, try firing up a command line and cd to C:\php and type php -v. This will output the PHP version, but will often spit out more error messages than are shown when loading a web page
