   root@me:~# sudo systemctl status apache2
sudo: unable to resolve host me

   Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled)

I run this command :

sudo systemctl status apache2

I saw this two part from request:

Jul 10 16:08:46 me systemd[1]: Failed to start LSB: Apache2 web server.

and

Jul 10 16:08:47 me apache2[9666]: ERROR: APACHE_PID_FILE needs to be defined in /etc/apache2/envvars

my question are why I have this error and are they something bad for me server , because I have two client in this server?

my version for me apache and linux:

root@me:~# apache2 -v

Server version: Apache/2.4.18 (Ubuntu) Server built: 2017-06-07T19:43:03 root@me:~#

Linux me 4.15.0-24-generic #26~16.04.1-Ubuntu SMP Fri Jun 15 14:35:08 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The first error message returned from your systemctl command is:

sudo: unable to resolve host me

As stated by roaima, the use of sudo is pointless, because you're already root and have all neccessary access rights as such. The sudo command can be used to acquire root rights, while you're logged in as an user.

The second error message returned from your systemctl command is:

/etc/init.d/apache2: 46: .: Can't open /etc/apache2/envvars

The /etc/apache2/envvars file is not available or you should provide access to it. Please check if the file is available first with the ls -l command. If the file exists, you should probably use the chown or chmod command to provide access.

The same question is answered here on stackoverflow . You can find further instructions to create an initial apache envvars configuration file by following the link.
