ubuntu6.06.2 LTS安装Darwin Streaming Serve流媒体服务器笔记
一 安装软件
首先上http://dss.macosforge.org/post/previous-releases/下载压缩文件，当前最新版本为6.0.3，但我选择了5.5.5版本，因为这个版本提供了针对linux的安装脚本。下载了DarwinStreamingSrvr5.5.5-Linux.tar.gz文件后，解压缩。
解压命令为：
~/tmp/$ tar -zxvf DarwinStreamingSrvr5.5.5-Linux.tar.gz
然后运行如下命令安装：
~/tmp/DarwinStreamingSrvrlinux-Linux$ chmod +x Install //如果已经有执行权限了这步自然就不用了
~/tmp/DarwinStreamingSrvrlinux-Linux$ sudo ./Install
输出为：

Darwin Streaming Server Setup
Inorder to administer the DarwinStreaming Server you must create anadministrator user [Note: Theadministrator user name cannot containspaces, or single or double quotecharacters, and cannot be more than255 characters long].
Please enter a new administrator user name: keensword007
Youmust also enter a password forthe administrator user [Note: Theadministrator password cannot containspaces, or quotes, either singleor double, and cannot be more than 80characters long].
Please enter a new administrator Password:
Re-enter the new administrator password:
Adding userName keensword007
chown: invalid user: `qtss'
Setup Complete!
从提示信息上看，应该是qtss用户未能创建造成的，查看了一下Install脚本，发现创建用户的脚本是这样的：
if [ $INSTALL_OS = "Linux" ]; then
/usr/sbin/useradd -M qtss > /dev/null 2>&1
else
/usr/sbin/useradd qtss > /dev/null 2>&1
fi
但是useradd并没有-M的命令行参数，应该为-m，将-M修改成-m后，再执行Install脚本。
输出中发现仍有问题，部分输出为：

Installation Complete
Darwin Streaming Server Setup
In order to administer the Darwin Streaming Server you must create an administrator user [Note: The administrator user name cannot contain spaces, or single or double quote characters, and cannot be more than 255 characters long].
服务无法启动Cannot switch to group qtss。查阅网络和书籍，执行如下命令：
root@root:~# grep -n qtss /etc/shadow /etc/passwd /etc/group /etc/gshadow
/etc/shadow:28:qtss:!:14753:0:99999:7:::
/etc/passwd:28:qtss:x:1001:100::/home/qtss:/bin/sh
root@root:~# groups qtss
qtss : users
发现问题为qtss用户组根本就没有建立，建立的qtss用户被默认设置users为初始用户组。于是进行如下修改：
root@root:~# groupadd -g 1001 qtss //建个立用户组qtss，指定GID为1001
root@root:~# usermod -g 1001 qtss //修改qtss用户的初始用户组为1001（即qtss用户组）
启动服务：
root@root:/etc# cd /usr/local/sbin/
root@root:/usr/local/sbin# ls
DarwinStreamingServer streamingadminserver.pl StreamingServerModules
root@root:/usr/local/sbin# ./streamingadminserver.pl
使用如下命令确定服务是否已经启动：
root@root:~# ps aux|grep Darwin
root 7509 0.0 0.0 4036 512 ? Ss 22:07 0:00 /usr/local/sbin/DarwinStreamingServer
qtss 7510 0.0 0.1 29488 3064 ? Sl 22:07 0:00 /usr/local/sbin/DarwinStreamingServer
1000 7772 0.0 0.0 2896 816 pts/1 S+ 23:01 0:00 grep Darwin
如果希望机器启动后自动运行流媒体服务器，输入如下命令：
~/tmp/DarwinStreamingSrvrlinux-Linux$ cd /etc/rc3.d
/etc/rc3.d$ sudo ln -s /usr/local/sbin/streamingadminserver.pl s20streamingserver
。如果要手动启动服务，运行streamingadminserver.pl程序。
二、配置
Darwin Streaming Server采用了web管理模式，可以在本机的浏览器中输入：http://服务器IP:1220 。然后输入在安装流媒体服务器时设置的用户名称和密码。
第一次登录时，接着会出现设置向导。首先是一个如图所示的MP3 广播密码设置对话框，在其“New Password”和“Re-enter New Password”输入自己想设置的密码。然后点击“Next”按钮继续。
为了保证数据传输的安全需要您可以在这里钩选“Secure Administration（SSL）”（安全管理），前提是您已经有了可用的SSL 证书。一般可以不选，如图 所示。直接点击“Next”按钮继续。
接下来要设置的是媒体文件的存放主目录， 其默认的目录为“如图所示。这个目录要记住，在服务器中以后添加媒体文件时就要加在这个目录中。设置完毕点击“Next”按钮继续。
最后设置默认传输端口，如果设置了“Streaming onPort80”则此服务器的访问可以突破防火墙，但如果您在此服务器上同时建有Apache等占用80端口的服务。则建议您不要设置此端口。这里如果您没有什么特殊要求的话，使用缺省配置即可，如图9 所示。直接点击“Finish”按钮。
自此流媒体服务器的设置就告一段落，如果您要作进一步的设置，可以通过此管理页面，在其左侧点击相应的选项，进行设置。也可以通过此对前面所做的设置进行更改。
三、在线播放
流媒体服务器部署完毕后，我们就可以使用自己喜欢的播放器在线播放了。例如，在本机上打开Movie Player, 在地址栏输入:
rtsp://服务器IP/sample_100kbit.mp4
就可以看到一段QuickTime演示视频。
