Apache2 restart failed on ubuntu

Question

when i am trying to restart apache server from ubuntu, its showing as fail... i typed the command as, $service apache2 restart

it shows,

• Restarting web server apache2 [fail]

when i checked in log file, in var/apache2/errorlog the description provided is,

[mpm_prefork:notice] [pid 1263] AH00163: Apache/2.4.7 (Ubuntu) PHP/5.5.9-1ubuntu4.5 configured -- resuming normal operations

Answer 1

It is most likely because you are not using sudo when running the command, try:

sudo service apache2 restart
