Windows 2016 IIS not listen on external IP
On a Windows 2016 server, IIS web site is set to bind on all IP address on the server.

But site is only available on 127.0.0.1 (localhost). To check if this is due to firewall, i disabled firewall, the problem still exists after disabling firewall.

To fix the problem, run following commands as user “Administrator”
```
netsh http show iplisten
netsh http delete iplisten ipaddress=127.0.0.1
netsh http add iplisten ipaddress=0.0.0.0
```

Install Apache and PHP 7 On Windows
Lets start with PHP. Go to

https://windows.php.net/download/

Decide which PHP version you need.

At the time of this post, PHP 7.2 is latest version is available in following 4 version

VC15 x64 Non Thread Safe
VC15 x64 Thread Safe
VC15 x86 Non Thread Safe
VC15 x86 Thread Safe

x64 vs x86

x64 is for 64 bit OS. Most computers these days are 64 bit.

Thread Safe vs Non Thread Safe

Download “Thread Safe” version if you are using PHP as Apache Module or IIS.

Non-Thread Safe version is for running PHP as FCGI process.

Exact and put the content of ZIP file in folder
```
c:\PHP7
```
Download and Install Apache

Download latest Apache version from

https://www.apachelounge.com/download/

Download 32 or 64 bit depending on your Windows install.

Since we are installing PHP compiled with VC15, we need Apache compiled with VC15. So i downloaded following

https://www.apachelounge.com/download/VC15/binaries/httpd-2.4.33-Win64-VC15.zip

The site have other version available for VC14 and VC11, this is useful if you are installing older version of PHP that is compiled with older Visual Studio C++.

Edit httpd.conf, add following to end of the file
```
LoadModule php7_module "c:/php7/php7apache2_4.dll"
AddHandler application/x-httpd-php .php
PHPIniDir "c:/php7/"
```
If you want to install Apache as Service, run
```
httpd -k install -n "Apache 2.4" 
```
-n “Apache 2.4” is the service name that will be visible in windows service manager.
