在网上看了不少安装red5-server的方法，在我电脑上都好像安装不成功，本来是很简单的事，因为刚接触，结果费了不少时间。这里整理出Ubuntu 16.04 成功安装的方法，以便给搭建一个参考。
（一）安装JDK
1. 终端输入：apt-cache search openjdk
运行结果：
linuxidc@linuxidc:~/test/RTMP$ sudo apt-cache search openjdk

Sorry, try again.

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
linuxidc@linuxidc:~$ java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-8u121-b13-0ubuntu1.16.04.2-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
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
linuxidc@linuxidc:~$ $JAVA_HOME
linuxidc@linuxidc:~$ echo export JAVA_HOME="/usr/lib/jvm/java-8-openjdk-amd64/">>~/.bashrc
linuxidc@linuxidc:~$ $JAVA_HOME
linuxidc@linuxidc:~$ source .bashrc
linuxidc@linuxidc:~$ echo $JAVA_HOME
/usr/lib/jvm/java-8-openjdk-amd64/
（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
FTP地址：ftp://ftp1.linuxidc.com
用户名：ftp1.linuxidc.com
密码：
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：:5080/ 出现下面界面表示安装成功。
