How to enable linux root access on Microsoft Azure Cloud
1. Login via ssh using your sudo user on your Microsoft Azure linux server
2. Now login as root user
[root@lin ~]# sudo su -
3. check if root access is set (LOCK means that root access is disabled)
[root@lin ~]# grep root /etc/shadow
Result:
root:*LOCK*:14600::::::
4. enable root access (as root user enter command passwd)
[root@lin ~]# passwd
5. Now enter your password and root access is enabled.
You can check this by using command “grep root /etc/shadow”
That’s all folks

You can enable IP Geolocation to have CloudFlare geolocate visitors to your website and pass the country code to you.
Redirect web traffic based on Country origin to subdomain or to different web site.
You will find the IP geolocation option by going to:
Webiste –>CloudFlare Settings –>IP Geolocation
Direct link is:
https://www.cloudflare.com/cloudflare-settings?z=YOURSITE
Once enabled, Cloudflare will then add a header called “CF-IPCountry” to all requests to your website.
Here are a couple of examples of how to access/store this value:
$country_code = $ENV{"HTTP_CF_IPCOUNTRY"}; # to access in Perl
$country_code = $_SERVER["HTTP_CF_IPCOUNTRY"]; // to access in PHP
CloudFlare includes this information for both IPv4 and IPv6 addresses
In your website code capture that header and redirect traffic.
Redirect web traffic based on Country origin PHP sample:
$country_code = $_SERVER["HTTP_CF_IPCOUNTRY"];
if($country_code=="US"){
$location='http://www.mysite.com/us';
}elseif($country_code=="UK"){
$location='http://www.mysite.com/uk';
}else{
$location='http://www.mysite.com/us';
}
header("location:$location");
exit;

Warning
This will erase all your emails from queue.

To enable themes you must install Less CSS via nodejs.
On Linux, use your distribution’s package manager to install nodejs and npm.
Warning
In debian wheezy and Ubuntu 13.10 and before you need to install nodejs manually:
$ wget -qO- https://deb.nodesource.com/setup | bash -
$ apt-get install -y nodejs
In later debian (>jessie) and ubuntu (>14.04) you may need to add a symlink as npm packages call node but debian calls the binary nodejs
$ apt-get install -y npm
$ sudo ln -s /usr/bin/nodejs /usr/bin/node
Once npm is installed, use it to install less and less-plugin-clean-css:
$ sudo npm install -g less less-plugin-clean-css
on OS X, install nodejs via your preferred package manager (homebrew, macports) then install less and less-plugin-clean-css:
$ sudo npm install -g less less-plugin-clean-css
on Windows, install nodejs, reboot (to update the PATH) and install less and less-plugin-clean-css:
C:\> npm install -g less less-plugin-clean-css
Warning
You can have problems with NodeJS and NPM packages in the Ubuntu 14.04 repository because they are outdated.
Follow the instructions from the NodeJS Website:
curl -sL https://deb.nodesource.com/setup_0.10 | sudo bash -
sudo apt-get install -y nodejs
sudo npm install -g npm (to update npm)
Then install Less and accessories:
sudo npm install -g less less-plugin-clean-css
