Simple guide to Configure APACHE webserver in RHEL/Centos/Oracle linux(5/6/7) step by step
In this tutorial
we learn how to configure APACHE webserver in linux(5/6/7) based of different
types of hosting. There is two types of hosing . one is IP based hosting and other
is named based hosting. We configure
both types of hosting in this tutorials.
What is APACHE webserver
APACHE web
server is an open source most widely used webserver software.67% of the
webserver are running on APACHE webserver all over the world. APACHE webserver
is very fast,secure and APACHE webserver is highly customizable and fit in
different environment.
Pre-requisite of configure APACHE webserver
To
configure APACHE webserver we need to install APACHE webserver package. To
install the APACHE webserver packages please follow the below link.
Configure APACHE webserver using IP based hosting
To
configure APACHE webserver based on IP ADDRESS we need ipaddresses based on how
many websites is going to host. If we have two websites we need two different
ip addresses for this.
Lests take
an example we have two websites which is example1.com and other is
example2.com. For this we have two different ip addresses 192.168.137.3 and
192.168.137.5. we can assign multiple ip address on a single NIC using ip aliasing
method.
After meet
all pre-requisite we can start the configuration part . For this we need to go
and edit “/etc/httpd/conf/httpd.conf” file
and create the VirtualHost .
Before
doing this activity we need to take backup the httpd.conf file to execute the
below command.
[root@localhost
~]# cp /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.conf.bak
After that
we create two VirtualHosts , to do this follow the below steps.
<VirtualHost
192.168.137.3:80>
ServerAdmin webmaster@example1.com
DocumentRoot /var/www/html/example1.com
ServerName example1.com
ErrorLog logs/example1.com
CustomLog logs/example1.com common
</VirtualHost>
<VirtualHost
192.168.137.5:80>
ServerAdmin webmaster@example2.com
DocumentRoot /var/www/html/example2.com
ServerName example2.com
ErrorLog logs/example2.com
CustomLog logs/example2.com common
</VirtualHost>
Now we have
to create the Document Root for the both websites. To create the Document Root we
need to go “/var/www/html” directory and create two directories one is “example1.com”
and other is “example2.com”. and them create index.html file inside the both
directories.
[root@localhost ~]# cd
/var/www/html
[root@localhost html]#
pwd
/var/www/html
[root@localhost html]#
mkdir example1.com
[root@localhost html]#
mkdir example2.com
[root@localhost html]#
cd example1.com/
[root@localhost
example1.com]# echo "welcome to example1" > index.html
[root@localhost
example1.com]# cd ..
[root@localhost html]#
cd example2.com/
[root@localhost
example2.com]# echo "welcome to example2" > index.html
After doing the above activity we
start the APACHE webserver using the below command.
For linux(5/6)
#service httpd start
For linux7
#systemctl start httpd
To verify the service we execute
curl command .
[root@localhost ~]#
curl http://192.168.137.3
welcome to example1
[root@localhost ~]#
curl http://192.168.137.5
welcome to example2

Simple guide to Configure APACHE webserver in linux(5/6/7) step by step
Configure APACHE webserver using NAMED based hosting
In NAMED based
hosting multiple websites can be hosted on a single ip address.
Lets take
an example we have two websites example1.com and example2.com which will be
hosted on a single ip address which is 192.168.137.3.
To
configure this we need to go to the configuration file of the APACHE webserver
and create the VIrtualHosts.
<VirtualHost
192.168.137.3:80>
ServerAdmin webmaster@example1.com
DocumentRoot /var/www/html/example1.com
ServerName example1.com
ErrorLog logs/example1.com
CustomLog logs/example1.com common
</VirtualHost>
<VirtualHost *:80>
ServerAdmin webmaster@example2.com
DocumentRoot /var/www/html/example2.com
ServerName example2.com
ErrorLog logs/example2.com
CustomLog logs/example2.com common
</VirtualHost>
After that search NameVirtualHost and uncomment the line add the below line
NameVirtualHost
192.168.137.3:80
Now we have
to create the Document Root for the both websites. To create the Document Root we
need to go “/var/www/html” directory and create two directories one is “example1.com”
and other is “example2.com”. and them create index.html file inside the both
directories.
[root@localhost ~]# cd
/var/www/html
[root@localhost html]#
pwd
/var/www/html
[root@localhost html]#
mkdir example1.com
[root@localhost html]#
mkdir example2.com
[root@localhost html]#
cd example1.com/
[root@localhost
example1.com]# echo "welcome to example1" > index.html
[root@localhost
example1.com]# cd ..
[root@localhost html]#
cd example2.com/
[root@localhost
example2.com]# echo "welcome to example2" > index.html
Now the start the APACHE web service
using the above steps.
Now open the browser and type
example1.com and example2.com we will find the different webpages.
