InstallingBigBlueButtonHow to install BigBlueButton like a real developer. :-)UpdatedFeb 15, 2011This guide has been updated for 0.71a and is currently DRAFT - if you are unable to complete these instructions, please post tobigbluebutton-setupand well correct any errors.This guide shows you how to install BigBlueButton from source on Ubuntu 10.04.x 32-bit.In most cases, youll want to install frompackages, but if you want to really understand how BigBlueButton is setup, go through the step-by-step instructions below and youll become familiar with each component.To start, youll need a computer running Ubuntu 10.04 32-bit or 64-bit, either a physical machine or a virtual machine (VM). When you boot your Ubuntu VM, it needs to have a network IP that you can access from another computer (such as the host computer running the VM).Also ensure that port 80 (HTTP), port 1935 (RTMP), and port 9123 (desktop sharing) are open on your server. Port 80 must not be already in use by another server (such as apache2).The instructions below assumes you are running a Ubuntu 10.04 VM with root access.Log in as rootLog in as root to avoid having to type sudo in front of most of the commands required to install BigBlueButton.sudo -iCheck if you have a internet connectionping If you get an error saying your eth0 is not connected, check if the VM is using eth1:ifconfig -aIf it shows the following:eth1 Link encap:Ethernet HWaddr 00:0c:29:dd:b4:51 inet addr:54 Bcast:55 Mask: inet6 addr: fe80:20c:29ff:fedd:b451/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4080349 errors:0 dropped:0 overruns:0 frame:0 TX packets:3932137 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1216680270 (1.2 GB) TX bytes:822963271 (822.9 MB) Interrupt:19 Base address:0x2000lo Link encap:Local Loopback inet addr: Mask: inet6 addr: :1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:12938 errors:0 dropped:0 overruns:0 frame:0 TX packets:12938 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:40299608 (40.2 MB) TX bytes:40299608 (40.2 MB)Make it use eth0 insteadvi /etc/udev/rules.d/70-persistent-net.rulesThis will show:# This file was automatically generated by the /lib/udev/write_net_rules# program, run by the persistent-net-generator.rules rules file.# You can modify it, as long as you keep each rule on a single# line, and change only the value of the NAME= key.# PCI device 0x1022:0x2000 (pcnet32)SUBSYSTEM=net, ACTION=add, DRIVERS=?*, ATTRaddress=00:0c:29:23:d1:b3, ATTRtype=1, KERNEL=eth*, NAME=eth1# PCI device 0x1022:0x2000 (pcnet32)SUBSYSTEM=net, ACTION=add, DRIVERS=?*, ATTRaddress=00:0c:29:dd:b4:51, ATTRtype=1, KERNEL=eth*, NAME=eth0Swap the two entries by editing NAME=eth1 to NAME=eth0 and vice versa.Reboot your machine. Check if you manage to connect to the internet. Make sure the VMs network adapter is using a Bridged connection instead of NAT. On the VMWare player this is enabled in the Devices menu at the top.More info can be found here/showthread.php?t=221768Update and Upgrade your VMOnce you have internet connection, update and upgrade your VM.apt-get updateapt-get upgradeInstall MySQLapt-get install mysql-serverWhen prompted, enter a password for the MySQL root account and keep this handy.Install Tomcatapt-get install tomcat6Confirm that tomcat is runninghttp:/:8080/To determine your ip:ifconfigsee ifconfig -a command above for output.

FreeSWITCH allows BigBlueButton to be integrated with a PBX system and when configured properly, can accept incoming calls from a SIP trunking provider. Since FreeSWITCH isnt in the Ubuntu repositories we need to add it to our sources. To do this:apt-get install python-software-propertiesadd-apt-repository ppa:freeswitch-drivers/freeswitch-nightly-drivers apt-get updateapt-get install freeswitch freeswitch-lang-enConfigure FreeSWITCHcd /opt/freeswitch/tar xzvf /tmp/bbb/freeswitch-config.tar.gzchown -R freeswitch:daemon confchmod -R 755 confsed -i s/FREESWITCH_ENABLED=false/FREESWITCH_ENABLED=true/g /etc/default/freeswitchConfigure NginxBe sure to replace with your IP or domain.cat /tmp/bbb/nginx-bigbluebutton.conf | sed s/5/ /etc/nginx/sites-available/bigbluebuttonEnable the bigbluebutton nginx configln -s /etc/nginx/sites-available/bigbluebutton /etc/nginx/sites-enabled/bigbluebuttonInstall OpenOfficeapt-get install Start openoffice as a serviceservice bbb-openoffice-headless startDisable Security settings for TOMCAT6sed -i s/#TOMCAT6_SECURITY=yes/TOMCAT6_SECURITY=no/ /etc/default/tomcat6 Setup the databasemysql -u root -pThis is an important step.
