Automatic www/non-www URL handling

When you set up a website, there are two ways people can access it: www.yourdomain.com, or just yourdomain.com. This creates a couple of problems. First, unless you've set the site's cookie domain to .yourdomain.com, when someone logs in at yourdomain.com they won't be logged in at www.yourdomain.com -- which leaves them confused if they end up on the other version from a link they found somewhere. Secondly, search engines don't like the duplication.

The solution for this has always been to add redirection into the .htaccess file to redirect www URLs to their non-www equivalents or vice versa. Many of you have done this in WSN using the extra .htaccess content option in the SEO settings.

The latest WSN 10 beta adds automatic handling of this situation, whenever URL rewriting is enabled on a site. It checks the directory url value to see whether you want www or not, so you can change it either by changing the directory URL at Admin -> Settings -> System Configuation or by changing the selection at Admin -> Settings -> SEO -> Domain Format (which will in turn update your directory URL for you). WSN writes the appropriate redirection rules to the .htaccess automatically.

Having a duplicate redirection (one you set in the extra .htaccess content as well as the new automatic redirection) shouldn't be a problem, works fine in my tests, so you don't have to change anything -- but can feel free to remove any redirection you added whenever you're ready, for clarity.

A Day in the Life of a Programmer

The reality of being a programmer is somehow portrayed on this GIF. This situation merely happens when a newbie programmer seeks help from a fellow programmer.

Sometimes, it is also a challenge for an expert programmer to extend help to our fellow programmer; but yes, reaching out a hand should never be a worry.

I hope you can relate on this GIF, and gracefully extend your expertise to help or teach those who are in need of you.

Though programming is hard to understand and to solve, it is always fun; and can even be more enjoyable with hands helping each other.

How to setup nameservers with BIND? CentOS Web Panel

Quick and easy info how to setup your own nameservers with CentOS Web Panel Server using BIND DNS Server.

CENTOS WEB PANEL – SYSTEM REQUIREMENTS

Make sure that you complete the following tasks before you start the installation process:

1. Setup Hostname

This hostname cannot be the same as any domain that is on your server (for example, if example.com is a domain on your server, use hostname.example.com as your fully qualified hostname).

You can use the following command for hostname setup eg. srv1.example.com

hostname srv1.example.com

2. Setup Server IP addresses

• Define additional IP address, subnet address, and default gateway IP address for your server — your service provider can provide you with this information.

3. Software Requirements

• You must have a clean/fresh installation of supported operating systems:
• CentOS 6, RedHat 6 or CloudLinux 6, MINIMAL installation and English version only!
• CentOS 7 is NOT supported.

4. Hardware Requirements

• 32 bit operating systems require a minimum of 512 MB RAM
• 64 bit operating systems require a minimum of 1024 MB RAM (recommended)
• Recommended System: 4 GB+ RAM so you would have the full functionality such as Anti-virus scan of emails.

Host Multiple Domains on One Server/IP with Apache or nginx

Configure Apache/Nginx to host multiple websites

If you are on dedicated or VPS like DigitalOcean or any other server and planning to host multiple websites on a single server then here is how you can do it either with Apache HTTP or Nginx web server.

This assumes you have already mapped DNS to your host, like following two domains I have mapped to DigitalOcean.

1. bestflare.com
2. usefulread.com

Before you implement this, to give you an idea how it works. The concept to have multiple websites on a single instance is called Virtual Server. Virtual server configuration is defined within web server configuration and based on server/IP address, a request is getting forwarded to respective Document Root.

Configure Virtual Host in Apache to host multiple domains

• Login into Apache HTTP Server
• Go to apache conf location. ( in default installation – you will find it here /etc/httpd/conf/httpd.conf)
• Take a backup of httpd.conf file
• Create a VirtualHost container like below I have done for two domains.

<VirtualHost *:80>
ServerAdmin hello@chandank.com
   DocumentRoot /opt/htdocs/bestflare
   ServerName bestflare.com
   ErrorLog logs/bestflare.com-error_log
   CustomLog logs/bestflare.com-access_log common
</VirtualHost>
<VirtualHost *:80>
   ServerAdmin hello@chandank.com
   DocumentRoot /opt/htdocs/usefulread
   ServerName usefulread.com
   ErrorLog logs/usefulread.com-error_log
   CustomLog logs/usefulread.com-access_log common
</VirtualHost>

Note: Change the value for ServerAdmin, DocumentRoot, ServerName, ErrorLog, CustomLog based on your requirement.

• Restart Apache HTTP and test both urls.

Configure Virtual Host in Nginx to host multiple domains

• Login into Nginx server
• Go to virtual.conf location (in default location – you will find it here /etc/nginx/conf.d/virtual.conf)
• Take a backup of virtual.conf
• Create server block for both URL’s as I have shown below.

server {
listen 80;
   root /opt/htdocs/bestflare;
index index.html index.htm;
   server_name bestflare.com;
   location / {
       try_files $uri $uri/ =404;
   }
}
server {
   listen 80;
   root /opt/htdocs/usefulread;
   index index.html index.htm;
   server_name usefulread.com;
   location / {
       try_files $uri $uri/ =404;
   }
}

Note: Change the value for root, server_name based on your requirement.

• Restart Nginx and test both URL’s
