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

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

Answer 1

Most likely, because you are not using sudo when running the command, try:

sudo service apache2 restart 

Answer 2

• In linux / ubuntu we can restart the application server: -

   sudo service apache2 restart 

• Differently

   sudo service apache2 reload
