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
:

After I have removed and reinstalled apache2 shows next message:

Answer
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
