Hello,

I did the install of BigBlueButton as shown on http://docs.bigbluebutton.org/install/install.html. When I run bbb-conf --check, here are the problems I'm getting.

** Potential problems described below **

# Warning: API URL IPs do not match host:

#

# IP from ifconfig: xx.xx.xx.xx

# /var/lib/tomcat7/webapps/demo/bbb_api_conf.jsp: mydomainname.com

#

# Warning: The API demos are installed and accessible from:

#

# Error: Unable to reach default URL for presentation:

#

Note that http://mydomainname.com is just a placeholder and not my actual domain name. I’m fairly new to BigBlueButton so any help will be appreciated. When I go to http://mydomainname.com on my browser, I’m getting the Welcome to Nginx page. When I go the demo page (http://mydomainname.com/demo/demo1.jsp ) I’m getting the 404 not found page. The same applies to when I go to the self-check page (http://mydomainname.com/check) and default URL for presentation (http://mydomainname.com/default.pdf). I tried to use bbb-conf –setip mydomainname.com but I’m still getting the same errors when I use bbb-conf --check. I made sure that the domain name resolves to the IP address in the warning (which is also <ip-address-2>). I’m not sure if it has anything to do with my firewall since I’m able to ping the IP address from an external device. Also, note that I did change the files according to this link http://docs.bigbluebutton.org/install/install.html#configuring-bigbluebutton-behind-a-firewall and I noticed that was when the FreeSWITCH error started happening. I reverted the files back to their defaults and I have been getting the FreeSWITCH error since then.

It might be that you have a public/private IP setup. Can you try using the bbb-install.sh script, see

https://github.com/bigbluebutton/bbb-install

as it can automate the configuration of the network (except any changes to your firewall/security group). It can also setup a Let's Encrypt certificate so you can use

https://mydomainname.com/

Try the above and let us know if it gets you going.

Regards,... Fred

Hello Fred,

I tried to run the following command as shown on the page you sent to me:

wget -qO- https://ubuntu.bigbluebutton.org/bbb-install.sh | bash -s -- -v xenial-200

But I'm getting this message:

bbb-install: You must unisntall apache2 first

I tried uninstalling apache2 on my server by using the following commands:

$ sudo apt-get remove --purge apache2 apache2-utils
$ sudo rm -rf /etc/apache2

I even used dpkg -l | grep -q apache2 to check if there are any apache2 packages and nothing shows up.

Never mind. I got the script to run but I'm still getting the same errors when I run bbb-conf --check.

Hi Alex,

> bbb-install: You must unisntall apache2 first

You need to install BigBlueButton 2.0 on a clean server -- one that does not have prior web applications installed (such as Apache2).

Is it an option for you to start over with a new Ubuntu 16.04 64-bit server that meets the minimal requirements, see

http://docs.bigbluebutton.org/install/install.html#minimum-server-requirements

Otherwise, your likely going to encounter a lot of resource conflicts that introduce subtle errors. See

http://docs.bigbluebutton.org/support/faq.html#we-recommend-running-bigbluebutton-on-port-80

Hello Fred,

Unfortunately, no it is not an option to start on a clean server. Is there another way I could work around these errors on my existing server? Also how do I fix this freeswitch error I got from my first post? The bbb-conf --check in my first post comes from my actual server and everything is the same with the exception of

# Error: FreeSWITCH is listening on IP address <ip-address-1> for SIP calls, but

# The IP address <ip-address-2> set bbb.set.app.ip.

The bbb-conf --check on my second post was from my VM on my desktop. I ran the script on a new virtual machine on my desktop and it works fine although when I uninstall bbb-demo I get the HTTP 404 not found page when I try to join a meeting.

Thank you,

Alex Nyamweya

Hi Alex,

> Unfortunately, no it is not an option to start on a clean server.

It makes it harder for others to volunteer their time to help out on such a setup as the resource conflicts are subtle and may not be immediately apparent.

> I ran the script on a new virtual machine on my desktop and it works fine although when I uninstall bbb-demo I get the HTTP 404 not found page when I try to join a meeting.

That's the correct result. See

http://docs.bigbluebutton.org/install/install.html#404-not-found

I noticed that the error about the red5 log files appeared after I ran bbb-conf --clean. Also I can't get freeswitch to run. When I use systemctl restart freeswitch I get the following error message:

I think I figured it out. I was able to install BigBlueButton on another clean server (this time I didn't install anything before bigbluebutton). It didn't work before because I had it setup as a LAMP server before I installed BigBlueButton. I didn't realize it was conflicting with the LAMP Server installation. Thank you very much for your help Fred! If anything comes up, I'll let you know.
