sudo tar zxvf apache-activemq-5.2.0-bin.tar.gz
sudo mv apache-activemq-5.2.0-bin.tar.gz /usr/local/activemq
启动ActiveMQ
sudo /usr/local/activemq/bin/activemq

10.修改tomcat6帐户
############################
tomcat6:x:106:113::/usr/share/tomcat6:/bin/bash

11.安装red5
cd /opt
sudo wget http://build.xuggle.com/job/red5_jdk6_stable/131/artifact/workingcopy/red5-0.8.RC3-build-hudson-red5_jdk6_stable-131.tar.gz
sudo tar zxvf red5-0.8.RC3-build-hudson-red5_jdk6_stable-131.tar.gz

用户tomcat用户启动red5
sudo su -l tomcat6
./red5.sh(需要root权限)

注：英文照考文档中是以上两行，而我在实际中使用tomcat用户启动red5 server是有很多[Error]提示。使用root启动就没那些Error，即使用sudo ./red5.sh命令启动。

sudo wget http://www.bigbluebutton.org/hudson/job/BBB-Trunk-Config/ws/web//*zip*/web.zip

19.禁用Tomcat6的Security设置
sudo vi /etc/default/tomcat6
把”#TOMCAT6_SECURITY=yes”换成”TOMCAT6_SECURITY=no”

20.安装数据库
mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 35
Server version: 5.0.75-0ubuntu10.2 (Ubuntu)

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

mysql> create database bigbluebutton_dev;
Query OK, 1 row affected (0.08 sec)

mysql> grant all on bigbluebutton_dev.* to ‘bbb’@'localhost’ identified by ’secret’;
Query OK, 0 rows affected (0.05 sec)

mysql> commit;
Query OK, 0 rows affected (0.00 sec)

21.安装BigBlueButton web

-bigbluebutton.web.serverURL参数替换成自己的IP地址”bigbluebutton.web.serverURL=http://192.168.2.125″
重启tomcat6

24.生成数据库
在浏览器的URL输入：http://<your ip_address>:8080/bigbluebutton就会自动生成bigbluebutton_dev数据库的所有表
测试一下:
> mysql -u root
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 56
Server version: 5.0.75-0ubuntu10.2 (Ubuntu)

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

# Location for recordings
recordingsDirectory=/var/bigbluebutton

# These properties are for Asterisk Management Interface (AMI)
ami.host=127.0.0.1
ami.port=5038
ami.username=bbb
ami.password=secret

-改变host=”conf/join-mock.xml”为host=”http://<your ip address:port>/bigbluebutton/conference-session/enter”

34.安装bbb默认主页
cd /var/www
sudo cp /home/user/temp/web.zip ./
sudo unzip -dc web.zip
sudo mv c/web ./bigbluebutton-default
