Apache Webserver Install on Linux

This document describe the process of installing Apache on RHEL.

Install Apache and Apache related tools:
```
sudo dnf install httpd httpd-tools
```
Check the version of Apache:
```
httpd -v
```
Start Apache:
```
sudo systemctl start httpd
```
Enable Apache to start at boot:
```
sudo systemctl enable httpd
```

Allow Apache to Make Outgoing Network Connections:

By default, SELinux forbids Apache to make outgoing network connections.

If Apache needs to make requests to an outside network service, then run the following command to allow this action.

setsebool -P httpd_can_network_connect on

Check Apache status and confirm that it’s listening on port 80:
```
sudo systemctl status httpd
```
Set the apache user as the owner of the web directory:
```
sudo chown apache:apache /var/www/html -R
```

Configure firewall to allow traffic to ports: 80 and 443:

sudo firewall-cmd --permanent --zone=public --add-service=http  (1)

sudo firewall-cmd --permanent --zone=public --add-service=https (2)

sudo systemctl reload firewalld (3)

1	Open port 80
2	Open port 443
3	Restart the FW daemon

Confirm Apache accessibility:
1. First create a test page:
  sudu vi /var/www/html/index.html
2. Enter the following html into that file:
  <h1 align="middle">Welcome - this is a test page!</h1>
3. Launch your browser and browse to the Linux server’s DNS name:
4. You should see the test page:
Apache is now installed.
