curl finds no route to host?

[TPeters]

I am doing the self-paced course RH294 . With two exercises (Ch.3 final Lab and Ch.4 lab exercise 2) I ran into this problem:

after installing and starting a web service, from the classroom web termicaI I cannot reach servera.lab.example.com with curl: "No route to host". This despite the fact that I can ping it, open a shell to it, and install the package on it with Ansible.

Anyone else have the same problem?

What might be the cause?

From what I can see, chapter 3 final lab (data review) uses serverb not servera and for exercise 2 of chapter 4 (control handlers) it doesn't open the firewall, as it is more about proving the function of the handlers rather than actually building another web server, so I don't think a response is expected and no curl test is asked for.

Hello @TPeters !

Thanks for reaching out !

For ch3s07 - you need to open a firefox browser and try to reach to serverb webserver : use the web_user and web_pass credentials to login and see that it is working fine : 

[TPeters]

Chetan (and pjentw), thank you for your response. Only now I find time to attend this again.

Indeed I ran it against serverb which is in the inventory, not servera. I did the curl myself because the lab-grade failed.

 I try to run the data-review again, but it now fails at another check:

[student@workstation ~]$ lab start data-review

I cannot copy content from the serverb console, but I looked and indeed there is no /var/www/html directory even though `yum info httpd` says the httpd package has been installed.

This problem did not occur the first time I ran this main.yml .

[TPeters]

Follow up:

I logged in on the serverb . From `rpm -q --whatprovides /var/www` I learned that it comes from the httpd-filesystem packakes. `yum info httpd-filesystem` says it was installed. `rpm install httpd-filesystem` says it has nothing to do. So I did `rpm reinstall httpd-filesysytem` and that created the /var/www/html/ .

To be continued.

[TPeters · Accepted solution]

Apparently `lab finish` removes (a.o.) the /var/www/* , but does not remove the httpd-filesystem package, possibly because other packages depend on it So serverb is left in an inconsistent state.

I now managed to run the `lab grade data-review` successfully, so consider this issue solved.

Hello @TPeters !

I see that you have figured out the issue yourself - great !

Let me know if you need any help or you have a question / feedback on this.

[satishmane]

check the permissions on firewall and the files as well in the playbook

Hello, i have run this chapter 3, s7. And successful completed the script and ran also successful. debug output: "serverb.lab.example.com(IP) has been customized by Ansible" but the grade from lab data-review. it saids reachable is fail. I have tested with curl and browser with web_pass / web_user with no problem. Am I something missed?
