Apache2 installation on Ubuntu 18.04 lts

Update your system to the latest using below mentioned commands.

sudo apt update

sudo apt upgrade

Installing Apache 2 server

Once the system is updated with latest patches , we can install

Apache 2 software using the following command

sudo apt install apache2

Enabling the apache2 service

To check if the service is enabled

sudo systemctl is-enabled apache2.service

If not already enabled we can use the systemctl commmand

as follows:

sudo systemctl enable apache2.service

Start/Stop/Restart commands for apache2 service:

sudo systemctl start apache2.service

sudo systemctl stop apache2.service

sudo systemctl restart apache2.service

To check the status of service:

sudo systemctl status apache2.service

If you are using ufw firewall we need to open a few ports to access

the apache server using following commands :

sudo ufw allow 80/tcp

sudo ufw allow 443/tcp

After opening the ports same can be verified as:

sudo ufw status

The last step after going through all this complete process would be to

test the installation of apache 2 server .

We can do that using curl command as:

curl -I http://ip-address-of-the-server
