What is a virtual hosting? It is a method that web servers such as lighttpd is use to host more than one domain name on the same server or on the same IP address. Virtual hosting can be accomplished in two methods such as ip-based virtual hosting and name-based virtual hosting. In this post, I will setup lighttpd 1.4.18 virtual hosting based on name-based virtual hosting to host domain1.com, www.domain1.com (both domain1.com and www.domain1.com is referring to the same website) and www2.domain2.com on 1 single web server.

1. Create each of the website directory like this: -

mkdir /srv/www/lighttpd/domain1.com
mkdir /srv/www/lighttpd/www2.domain2.com

2. Open lighttpd configuration file like this: -

vi /etc/lighttpd/lighttpd.conf

3. Add below text to support domain1.com and www.domain1.com at the end of file: -

$HTTP["host"] =~ “^(domain1.com|www.domain1.com)” {
server.document-root = "/srv/www/lighttpd/domain1.com"
}

4. Add below text to support www2.domain2.com at the end of file: -

$HTTP["host"] == “www2.domain2.com” {
server.document-root = "/srv/www/lighttpd/www2.domain2.com"
}

5. Save and exit file. Restart the lighttpd service like this: -

service lighttpd restart

6. Upload respective HTML files. Point your browser to the website and you will see the respective website.

Why lighttpd and not Apache? First of all, what is lighttpd? These four words can describe lighttpd - security, speed, compliance, and flexibility. lighttpd (pron. lighty) is a web server that has been optimized for high performance environment. With its very low memory footprint compared to other web servers, takes care of CPU load and advanced feature-set (FastCGI, CGI, Auth, Output-Compression, URL-Rewriting and many more) makes lighttpd the perfect web server software for every server that suffers load problems. Best of all lighttpd powers several popular Web 2.0 sites like YouTube, wikipedia and meebo.

Let’s get started. I am running CentOS 5 64-bit. You can’t get lighttpd from the official CentOS 5.0 repositories. We have to download lighttpd from DAG RPM Repository. Let’s download these packages lighttpd and lighttpd-fastcgi like this: -

wget -c http://dag.wieers.com/rpm/packages/lighttpd/lighttpd-1.4.18-1.el5.rf.x86_64.rpm

wget -c http://dag.wieers.com/rpm/packages/lighttpd/lighttpd-fastcgi-1.4.18-1.el5.rf.x86_64.rpm

Next, we can install the lighttpd and lighttpd-fastcgi like this: -

rpm -ivh lighttpd-1.4.18-1.el5.rf.x86_64.rpm lighttpd-fastcgi-1.4.18-1.el5.rf.x86_64.rpm

Next, we can update the runlevel information for system services so lighttpd start up automatically whenever the system boots like this: -

chkconfig --levels 235 lighttpd on

service lighttpd start

lighttpd’s default document root is at /srv/www/lighttpd and the configuration file is at /etc/lighttpd/lighttpd.conf on CentOS 5.

Simply create an index.html file and upload to the lighttpd document root. Now, point your favorite web browser to the lighttpd IP address and you will see the index.html file you created.

With the recent mitigation spam exercise in TM Network, I received phone calls from my friends complaining on unable to access remote SMTP server listening on port 25 from TM Network. TM Net took an immediate action on the same day itself the email notification was sent out as well as the news notification was published in their website. I quickly relay this message to my friends and they got frustrated. To overcome this email relay issue on SMTP port 25, some of the local web hosting provider had created an additional SMTP port for email relaying to their affected clients.

So, I would like to share on how to setup EXIM, QMAIL or SENDMAIL to listen on additional SMTP port using iptables in a Linux mail server box if you are a web hosting provider or you have a co-located server in a data center. Make sure iptables is installed. Just run the following command below: -

/sbin/iptables -t nat -A PREROUTING -p tcp -m tcp --dport 2525 -j REDIRECT --to-ports 25

The iptables command above will redirect any request access to TCP destination port 2525 to port 25. You can change the port number 2525 to your preferred port number. Hope this help you guys. Good nite.

I had been assigned a task to create a simple script for finding and deleting files older than 1 day, 7 days and 30 days for a backup directory. As usual, I will use Google (the ultimate search engine) to search for my answer. I found the answer from the How-To Geek.

Below is my simple script: -

#!/bin/bash

FIND=`which find`
RM=`which rm`

DPATH="/backup/daily"
WPATH="/backup/weekly"
MPATH="/backup/monthly"

DDAYS="+1"
WDAYS="+7"
MDAYS="+30"

if [ $# -lt 1 ]
then
echo "Usage: ${0##*/} [daily/weekly/monthly]“
exit 1;
fi

if [ $1 == daily ]
then
$FIND $DPATH -mtime $DDAYS -exec $RM {} \;
exit 1;
fi

if [ $1 == weekly ]
then
$FIND $WPATH -mtime $WDAYS -exec $RM {} \;
exit 1;
fi

if [ $1 == monthly ]
then
$FIND $MPATH -mtime $MDAYS -exec $RM {} \;
exit 1;
fi
