EvE is not working due to Apache2 server

[digital]

Hi all,

I had an issue initially when upgrading to version 2.0.3-76 whereby Apache Server not starting automatically when Ubuntu Server boots up. I had to start it manually each time. Then I thought upgrading to version 2.0.3-77 will fix the issue but it was not. I tried uninstalling apache2 "sudo apt-get purge apache2" and reinstall EvE-NG with "DEBIAN_FRONTEND=noninteractive apt-get -y install eve-ng" where it also installed the Apache Server again but when i try to open up the GUI i get this error:

What should i do to fix the EvE-NG GUI? I use a bare metal server and i don't want to reinstall everything back from scratch!

Thank you in advance.

Thank you in advance.

Looks like you messed up the installed packages.
When Apache not running, you can make it work by setting up start automatically every time you reboot. not to uninstall the packages.

can you do

apt-get update
apt-get dist-upgrade

See if the issue fixes.

R!

[ecze]

systemctl status apache2
systemctl restart apache2
journalctl -xe

Give here the output please...

Hi ecze & ramindia,

Thanks a lot for your replies. Yes, after i "purged" the apache i did a re-install and tried to "update" & "dist-upgrade" but still the issue was presistant as i described earlier. Anyways, for the sake of helping anyone who may run into this issue, after I did some troubleshooting of the issue, i was able to get the EvE GUI back when i noticed some php linked files were missing in the Apache installation.

2 link files were missing in the "/etc/apache2/mods-enabled" folder: "php7.0.conf" & "php7.0.load" after recovering them and restarting the apache service, I got back the EvE GUI working.


Regardless of fixing the EvE GUI, the apache is still running on manual start, which means i have to run the "/etc/init.d/apache2 start" command each time i boot up my server.

Here are the show commands:

When I upgraded to the version before-last (that is version .76), i used "sudo update-rc.d apache2 enable" command to get the Apache running automatically when the server boots. However, When I upgraded to version .77 this command now has no affect and I'm back to manual start of the Apache service!

It looks like some MySQL and the new CPUlimit feature is causing me some problems.

Any thoughts are very much appreciated.
Thank you all once again!

make sense, with the output your config fixed.

R!
