（一）安装JDK
1. 终端输入：apt-cache search openjdk
运行结果：
2.这里我们安装openjdk-8-jdk，因为我安装openjdk-9-jdk的时候有出错。
运行安装命令：
sudo apt-get install openjdk-8-jdk
3.测试是否安装成功：java -version
4.配置java_home变量:
运行：echo export JAVA_HOME="/usr/lib/jvm/Java-8-openjdk-amd64/">>~/.bashrc 添加变量
source .bashrc 使变量生效
（二）安装red5
1.下载red5 Linux 安装包：https://github.com/Red5/red5-server/releases ，国外网站，下载很慢
------------------------------------------分割线------------------------------------------
red5-server-1.0.9-M6也可以到Linux公社1号FTP服务器下载
在 2017年LinuxIDC.com/9月/Ubuntu 16.04 安装搭建Red5流媒体服务器/
------------------------------------------分割线------------------------------------------
2.创建目录：
mkdir -p /usr/share/red5
3.设置环境变量：
export RED5_HOME=/usr/share/red5
4.将安装包解压到目录
/usr/share/red5
5. 开始运行red5
cd /usr/share/red5
./red5.sh &
6.结束运行red5
cd /usr/share/red5
./red5-shutdown.sh
安装结束
测试red5是否安装成功：
（1）运行red5
（2）浏览器输入：本地IP:5080
比如我的IP地址为192.168.0.6，则输入：http://192.168.0.6:5080/ 出现下面界面表示安装成功。
