Attaching screenshot

Hello, @Priyanka
Because version has been changed.
You can try below one,

$ sudo curl -O https://downloads.apache.org/tomcat/tomcat-8/v8.5.61/bin/apache-tomcat-8.5.61.tar.gz

rest steps is same.
You can cross verify of available version by visiting that site (https://downloads.apache.org/tomcat/tomcat-8/v8.5.61/bin/).

Let me know if you are still facing the issue.

I had tried it with latest version as well.
But it is working now.
Thanks!

Good to hear that, :+1:

hi @Tej-Singh-Rana / @Ayman

When same thing is attempted on v9.0.41 I do not get this error.

Can you please investigate and suggest why there is error in version suggested earlier v8.5.61 but this error is not seen when V9.0.41 is chosen.

Am I missing anything ?

Output is provided below

Output of extraction is ommited due to limitation imposed on characters . But this is enough for me to pass the checks at the end if I manually create directory with -8 just for sake of passing.

Hello @Ayman facing couple of issues while performing the followup task

Now run tomcat with default settings Open the http://localhost:8080 tab to see the tomcat web page in web browser

  1. There two download options in the tomcat webpage one with bin and another src
    https://downloads.apache.org/tomcat/tomcat-8/v8.5.63/
    a .Which one should be downloded? both or only the tar file present in bin directory. As per this page both needs to be downloaded
    b. If I just download bin there is no bin folder within it neither it has startup.sh file

  2. I can find the startup.sh file if I download the tar file present in the src path from the above link. However while trying to execute sudo ./startup.sh I am getting an error command not found. I am sure I am missing some steps here since I have tried the same steps in my own centos virtual system, and it give me the same error. So I don’t think this is an issue with the lab but with my steps.

Can you please explain what is going wrong here?

Hello, @praddasg
In lecture, provided a URL to download a package:

http://tomcat.apache.org/download-80.cgi

You have to copy a link of tar file from core binary distribution section:

https://downloads.apache.org/tomcat/tomcat-8/v8.5.63/bin/apache-tomcat-8.5.63.tar.gz

Then install the wget package, if it’s not available on a server.

sudo yum install -y wget

If it’s already available then download the package:

wget <apache-tomcat download path>

Extract it tar file,

tar xvf apache-tomcat-8.5.63.tar.gz

Under the apache-tomcat-8.5.63/bin directory, you will see startup.sh file. Execute it.

./startup.sh

then check it from top of the terminal localhost:8080.

From this URL, https://downloads.apache.org/tomcat/tomcat-8/v8.5.63/
You have to download a tar file(which is apache-tomcat-8.5.63.tar.gz) from the bin directory. Extract it from tar then execute it the same as above.

Hello @Tej-Singh-Rana, thanks for explaining this, I was literally checking the website https://downloads.apache.org/tomcat/tomcat-8/v8.5.63/ and did not find any tar package so went in to the bin folder and the package name ends with deployer, which does not have the startup.sh file. I tried the src folder, it does have the startup.sh file but when I tried executing it, it was giving me error bad command

But if I simply use the path which you mentioned, i can see the details.
https://downloads.apache.org/tomcat/tomcat-8/v8.5.63/bin/apache-tomcat-8.5.63.tar.gz

Note: As of now to test the url, i downloaded in my local machine but yet to try out the process in linux machine. But I think this will work.

Moral of the story, the url actually confused me while looking in the browser.
