How to change apache port?

Question

Apache HTTP Server

I have apache on port 80. I want to change it, for example, to 8080...
Changing /etc/apache2/ports.conf here does not help. After restarting apache, the port is restored to 80. I changed it in other places - the same thing ...
Tell me the right option?

Answer 1

here /etc/apache2/ports.conf

NameVirtualHost *:8080
Listen 8080

and here /etc/apache2/sites-available/default
sudo service apache2 restart

Answer 2

sed -i 's/:80>/:8080>/g' /etc/apache2/sites-available/*.vhost
sed -i 's/80/8080/g' /etc/apache2/ports.conf
sed -i 's/:80/:8080/g' /etc/apache2/sites-available/default

/etc/init.d/apache2 restart
