Linux搭建流媒體技術
1. 確定JDK的版本：
rpm -qa | grep jdk
rpm -qa | grep gcj
可能的結果是：
libgcj-4.1.2-42.el5
java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
2.然後解除安裝：
yum -y remove java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
如果這中方法不行，可以使用如下的方法解除安裝：
1）解除安裝系統自帶的jdk版本：
檢視自帶的jdk：
#rpm -qa|grep gcj
可能看到如下類似的資訊：
libgcj-4.1.2-44.el5
java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
使用rpm -e --nodeps 命令刪除上面查詢的內容：
#rpm -e –nodeps java-1.4.2-gcj-compat-1.4.2.0-40jpp.115
2）解除安裝rpm安裝的jkd版本
檢視安裝的jdk：
#rpm -qa|grep jdk
可能看到如下類似的資訊：
jdk-1.6.0_22-fcs
解除安裝：
#rpm -e --nodeps jdk-1.6.0_22-fcs
3）找到jdk安裝目錄的_uninst子目錄
·在shell終端執行命令./uninstall.sh即可解除安裝jdk
一、安裝
0、安裝java
yum install java-1.7.0-openjdk
1、下載
選擇red5-server-1.0.6-RELEASE-server.tar.gz，解壓到 /usr/local/red5
2、設定為可執行
- cd /usr/local/red5
- chmod +x *.sh
3、安裝
./red5.sh
4、編輯配置檔案
找到：/usr/local/red5/conf/red5.properties
編輯內容：修改IP地址和埠號

找到/usr/local/red5/webapps/live/WEB-INF/red5-web.properties檔案，增加IP地址。
如：
webapp.contextPath=/live
webapp.virtualHosts=192.168.1.160
二、新增服務啟動項
1、編輯啟動指令碼
vi /etc/init.d/red5
- #!/bin/bash
- # For RedHat and cousins:
- # chkconfig: 2345 85 85
- # description: Red5 flash streaming server
- # processname: red5
- # Created By: Sohail Riaz ([email protected])
- PROG=red5
- RED5_HOME=/usr/local/red5
- DAEMON=$RED5_HOME/$PROG.sh
- PIDFILE=/var/run/$PROG.pid
- # Source function library
- . /etc/rc.d/init.d/functions
- [ -r /etc/sysconfig/red5 ] && . /etc/sysconfig/red5
- RETVAL=0
- case "$1" in
- start)
- echo -n $"Starting $PROG: "
- cd $RED5_HOME
- $DAEMON >/dev/null 2>/dev/null &
- RETVAL=$?
- if [ $RETVAL -eq 0 ]; then
- echo $! > $PIDFILE
- touch /var/lock/subsys/$PROG
- fi
- [ $RETVAL -eq 0 ] && success $"$PROG startup" || failure $"$PROG startup"
- echo
- ;;
- stop)
- echo -n $"Shutting down $PROG: "
- killproc -p $PIDFILE
- RETVAL=$?
- echo
- [ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/$PROG
- ;;
- restart)
- $0 stop
- $0 start
- ;;
- status)
- status $PROG -p $PIDFILE
- RETVAL=$?
- ;;
- *)
- echo $"Usage: $0 {start|stop|restart|status}"
- RETVAL=1
- esac
- exit $RETVAL
2.將啟動指令碼新增到服務
- chmod +x /etc/rc.d/init.d/red5
- chkconfig --add red5
- chkconfig red5 on
3.設定CentOS防火牆
開啟5080、1935等埠
4.啟動red5
/etc/init.d/red5 start
5.測試Red5
在瀏覽器中訪問 http://yourip:5080
這裡我們訪問Red5自帶的幾個demo來測試Red5是否好用
Red5 多媒體服務佔用埠 5080，RTMP 佔用埠 1935，如果不能訪問，請檢查防火牆是否允許這兩個埠。
6.直播地址
rtmp://yourip/live/流地址
在配置檔案中按內網ip設定，在頁面檔案中按公網ip設定或相對路徑設定即可
