Now we are going to verify whether our Apache Web server lab setup is properly working or not, connectivities
there or not.
So in our case, the lab is that mean
master.example.com, we have installed the Apache Web server and plus another required packages
and it is centos 7.
base system and IP addresses 172.24.0.1.
And we have got another system C10 and C20, C10 having the ip address 172.24.0.10
and C20 having the address 172.24.0.20 and we have got a different browsers installed.
elinks, lynx and curl on both the systems and plus another utilities.
So now we will go to the C10 system and we will try to send two ping packets to our one system and we
will see whether the connectivity is there or not.
If the ping in our case when we do this, it is showing that two packets transmitted to receiver that mean
there is connectivity between C10 and our master system on which we are going to implement the Apache
Web server, then we will check the ping connectivity from C20 system.
Again, we will run this command ping -c2 means send two packets to which system 172.24.0.1
again it is showing the communication is there.
Then we will see whether we can connect to our web server or not from C10 system.
So we have got three browsers available.
elinks, we are going to say elinks --dump.
Very useful option.
Please dump the web page http://172.24.0.1.
It will say that connection refused.
Then we will verify with the curl Browsr again curl http and then the address of our system, Master system,
172.24.0.1.
It is also going to say Connection refused.
And then we are going to third browser lynx --dump http://172.24.0.1.
So again, it is saying unable to connect.
So why it is not able to connect.
Although we have installed the packages on Master, now in Master system, we have installed the web server,
but we have not activated that.
That means we have not started the server.
We have only installed that mean on Linux system.
Just installing that package is not sufficient.
Now you have to configure that system.
You have to then start that server.
in linux server is also called Deamon.
So we have to start that Deamon, temporary and permanent.
So from C10, no web connectivity, is there
And then we will check from C20 system also by using elinks dump command and it will again show that connection
refused with curl command with the lynx command.
It is going to show that it is not able to connect.
So it verifies that a ping is working.
But although we have installed a web server, but that is not configured or it is not running.
So in next few videos we will be seeing how to implement a single website on a using Apache website or
how to configure that.
So now let us verify whether that connectivity is there or not.
