00:00:06,780 --> 00:00:13,250
So let's have a look at the solution
for this lab on Red Hat. And I actually

2
00:00:13,250 --> 00:00:19,719
want to reconfigure it. So sudo vim on
etc HTTP conf Let's get back. So let me

3
00:00:19,719 --> 00:00:26,189
edit the configuration file and in the
configuration file I'm looking for the listen parameter.

4
00:00:26,210 --> 00:00:29,269
Now next and next and
there I can see listen 80.

5
00:00:30,050 --> 00:00:31,230
I'm changing that
to listen 82.

6
00:00:33,929 --> 00:00:39,649
Then we need to do something with ports,
right? What I would recommend is sudo semanage port.

7
00:00:41,689 --> 00:00:45,689
What I would recommend is
you use man semanage port.

8
00:00:47,100 --> 00:00:48,270
That's
giving information.

9
00:00:48,890 --> 00:00:52,189
Many man pages have useful examples
near the end of the man page.

10
00:00:53,259 --> 00:00:54,170
This is
what I need.

11
00:00:54,909 --> 00:00:57,570
Let me copy this and
change it a little bit.

12
00:01:00,979 --> 00:01:06,236
Sudo followed by the Command followed
by TCP. Well, we make that TCP

13
00:01:06,236 --> 00:01:11,493
82, right? And that allows the
web server to bind to port 82.

14
00:01:11,493 --> 00:01:16,750
Then there is one thing
remaining and that is the firewall.

15
00:01:17,230 --> 00:01:22,444
Well, let's use sudo
firewall cmd help grab port

16
00:01:22,444 --> 00:01:27,659
because I never remember
the syntax about it.

17
00:01:28,819 --> 00:01:32,879
Here we can see
add port is portid protocol.

18
00:01:35,760 --> 00:01:41,284
So sudo firewall cmd add
port is 82 TCP and

19
00:01:41,284 --> 00:01:46,810
that should make the web
server available on port 82.

20
00:01:48,010 --> 00:01:52,340
Did I ever restart the
web server? I did not.

21
00:01:52,340 --> 00:01:56,670
So. So sudo systemctl
restart httpd and we're done.

22
00:01:57,109 --> 00:02:03,215
Final check is sudo systemctl status on
httpd and we can see that it is

23
00:02:03,215 --> 00:02:09,319
listening on port 82. And that's what
we wanted. That's the end of the lab.
