Hi everyone.

I successfully installed OOD 2.0.9  
I have another Apache on port 80. So,

1. I change the “port” in `/etc/ood/config/ood_portal.yml` to the 8181
2. `sudo firewall-cmd --zone=public --add-port=8181/tcp --permanent && sudo firewall-cmd --reload`
3. `sudo /opt/ood/ood-portal-generator/sbin/update_ood_portal`
4. `sudo systemctl try-restart httpd24-httpd.service httpd24-htcacheclean.service`  
but httpd24 wont start and `systemctl status -l httpd24-httpd.service` says:

```auto
httpd-scl-wrapper[6913]: (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
httpd-scl-wrapper[6913]: (98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80

```

How can i effectively change the OOD Apache port?

Hi Mohsen! Sorry about the port trouble. Just a couple quick questions.

After running update\_ood\_portal can you see the changes applied in the config file for httpd in  
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf?

Do you see any entry in that ood-portal.conf file that is trying to use port 80 as well?

```auto
cat /opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf | grep 80

```

The out is just:

```auto
  OIDCSessionInactivityTimeout 28800
  OIDCSessionMaxDuration 28800

```

Thanks for the update. Since I’m not seeing that port being set in the ood\_portal.conf, and you mentioned apache is using port 80 elsewhere, it would help to know what else is using the port.

Could you run:  
`grep -r 80 /opt/rh/httpd24/root/etc/httpd/conf.d/ | grep -v '#'`

Mainly looking to see if there are any particular addresses binding to the port before a global bind, but also to make sure there isn’t some strange duplication going on.

Also, when you set the port initially, did you set the `listen_addr_port: 8181` in `ood_portal.yml` as well?

The output of `grep -r 80 /opt/rh/httpd24/root/etc/httpd/conf.d/ | grep -v '#'` is:

```auto
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf: OIDCSessionInactivityTimeout 28800
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf: OIDCSessionMaxDuration 28800
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf.20210615T162853:<VirtualHost *:80>
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf.20210615T162853: RewriteCond %{HTTP_HOST} !^(172.21.99.43(:80)?)?$ [NC]
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf.20210615T162853: RewriteRule ^(.*) http://172.21.99.43:80$1 [R=301,NE,L]
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf.20210615T162853: OIDCSessionInactivityTimeout 28800
/opt/rh/httpd24/root/etc/httpd/conf.d/ood-portal.conf.20210615T162853: OIDCSessionMaxDuration 28800

```

The result is same with or without `listen_addr_port: 8181` !

Also, visiting `172.21.99.43:8181` shows up OOD portal which is natural but `172.21.99.43:80` :

Just to be sure, the OOD portal is now showing up for you on port `8181`, is that correct?

The default apache page is likely showing because of the default apache config itself at:  
`/opt/rh/httpd24/root/etc/httpd/conf/httpd.conf`

Find the listen directive in that conf and comment it out:  
`#Listen 80`

And that should stop the requests on port `80` from being served after reloading the apache config.

Thank you @travert

Commenting out the default port in `/opt/rh/httpd24/root/etc/httpd/conf/httpd.conf` solved the problem. 👍
