Apache2 is not working - php

Question

I use Linux Mint. When I try to restart apache displays next message. Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details. Here the next error tex that displays systemctl status `apache2.service
:

Answer 1

In the log it is shown that port 80 (of apache2 is used by another application):-
May 31 14:40:49 alpha-To-be-filled-by-O-E-M apache2[23986]: (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
To resolve this stop the existing running application and try to start apache2.
To check the running application on port 80:-
sudo lsof -i:80
Take the pid of the running application and kill the application using below command:-
sudo pkill -9 <pid of running application>
Run the apache2 application again:-
sudo service apache2 start

Answer 2

export APACHE_PID_FILE=/var/run/apache2/apache2$SUFFIX.pid
Add this line in your /etc/apache2/envvars file
if there is no suffix then you have to add
#for supporting multiple apache2 instances
if [ "${APACHE_CONFDIR##/etc/apache2-}" != "${APACHE_CONFDIR}" ] ; then
SUFFIX="-${APACHE_CONFDIR##/etc/apache2-}"
else
SUFFIX=
fi
UPDATE
no listening sockets available. You are facing this issue because another application/service acquired port 80 on your Ubuntu Server.
Now you need to Kill the process which acquired port 80. You can find that easily with following command :-
sudo netstat -ltnp | grep ':80'
This will return something like :-
tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 1588/aolserver4-nsd
for above case Process number 1588 acquired port 80 , you need to kill that process 1588.
sudo kill -9 1588
Now you can start your apache
Solution 2
go to /etc/apache2/ports.conf and uncomment Listen 80

**If your Apache2 is not working and it returns like this **

don't worry I have a solution for you
firstly check-in your machine is there Nginx service is running in your system using
sudo systemctl status nginx.service
if it is running stop the service using
sudo systemctl stop nginx.service
and then check port 80 is there any process running on that port using
sudo lsof -i tcp:80
output:
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
anydesk 950 root 22u IPv4 39398 0t0 TCP bitcot-Latitude-7480:35993->hosted.by.datacamp.co.uk:http (ESTABLISHED)
kill the process using
sudo kill 950
Now your apache2 is ready, To start service open a new terminal Ctrl + Ail + T and start service using
sudo systemctl start apache2
here you go
