cd /opt/red5/dist
./red5.sh > start.log &

Install/update applications in the /opt/red5/dist/webapps folder .  For changes to take effect, Red5 must be restarted:

1. Check if red5 is running:
ps aux | grep red5

2. Go to its folder and shut red5 down:
cd /opt/red5/dist
./red5-shutdown.sh

3. See if it’s still running or not:
ps aux | grep red5

4. Restart it, and also make it output the logs into a file of your choice:
./red5.sh > start.log &

export JAVA_OPTS=”-Xrs -Xms128M -Xmx256M -Dsun.rmi.dgc.client.gcInterval=300000 -Dsun.rmi.dgc.server.gcInterval=360000 -Djava.net.preferIPv4Stack=true -XX:+ExplicitGCInvokesConcurrent -XX:+UseConcMarkSweepGC -Xverify:none”

Assuming red5 was installed in /opt/red5/dist admin will often need to restart it or check if it’s running.

Make sure Red5 restarts: restart.sh

#!/bin/bash
#Restart the process
#First see if running
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v restart | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
cd /opt/red5/dist
if [ -z "$PID" ]
then
#not running
echo “Red5 was not running at `date`” >> /opt/red5/dist/run-restart.log
else
echo “Red5: $PID”
#shutdown
/opt/red5/dist/red5-shutdown.sh
sleep 6
#make sure
kill $PID >> null
sleep 2
fi
#start
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “On request restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log

Mare sure Red5 process is running, if not start it: running.sh

#!/bin/bash
#set environment
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v running | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
if [ -z "$PID" ]
then
#Restart the process
cd /opt/red5/dist
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “Restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log
else
#do nothing
echo “Red5 is already running with PID=$PID at `date`” >> /opt/red5/dist/run-checked.log
fi

]]> http://www.videochat-scripts.com/red5-linux-server-optimizations-and-tools/feed/ 0 Install Red5 0.9 on Linux Ubuntu http://www.videochat-scripts.com/install-red5-0-9-on-linux-ubuntu/ http://www.videochat-scripts.com/install-red5-0-9-on-linux-ubuntu/#comments Wed, 07 Oct 2009 14:34:25 +0000 VideoChat Scripts http://www.videochat-scripts.com/?p=146 This post shows how to install latest Red5 from trunk on Linux Ubuntu.

For other linux flavors (i.e. Centos) see this comprehensive tutorial Install Red5 and JDK on Centos.

This installation was done from windows so we used  WinSCP and PuTTy (free software)  and was inspired from online tutorials.
This installation was done fluently: if you go to other folders and do other tasks during the installation make sure you return to the right folder before resuming.

First installed required packages one by one:
apt-get install subversion
apt-get install java-package
apt-get install sun-java6-jdk
apt-get install ant

Used arrows to browse to the Ok and confirm on jdk installation dialogs.

Verified installed java version:
java -version

Downloaded latest Red5:
mkdir -p ~/svn/red5
cd ~/svn/red5
svn co http://red5.googlecode.com/svn/java/server/trunk red5

Build Red5 with Ant:
export JAVA_HOME=/usr/lib/jvm/java-6-sun/
export ANT_HOME=/usr/share/ant/
cd ~/svn/red5/red5
/usr/share/ant/bin/ant

Installed Red5:
mkdir /usr/share/red5
cp -R dist/* /usr/share/red5/
cd /usr/share/red5
chmod 755 red5.sh
chmod 755 red5-shutdown.sh

Started Red5:
./red5.sh > start.log &

Verified opened ports:
netstat -ant

To install a new rtmp application you need to:

  1. Copy application to /usr/share/red5/webapps (i.e. /usr/share/red5/webapps/videowhisper as explained on VideoWhisper RTMP Applications)
  2. Shutdown red5
    cd /usr/share/red5
    ./red5-shutdown.sh
  3. Restart red5
    ./red5.sh

An alternative to doing the red5 installation yourself would be to order red5 installation .

If you don’t have the time and experience to run your own server or vps, you should use managed red5 hosting .

Updated for JDK 1.6.20 .
Updated for ANT 1.8.1 .

Here is how we installed latest Red5 and JDK on a server with Linux CentOS . These hints can help you install on many linux VPS or Dedicated enviroments.  We mainly do software development and work from windows, so we use WinSCP and PuTTy (free software). We browsed a lot of tutorials and web pages to get instructions that installed latest versions.

First, we made sure we have all prerequisites to install the rpm:

yum install rpm-build redhat-rpm-config

Allow required ports (not necessary if already opened): 3690 (svn), 5080, 1935, 1936, 8088.  See more details at the end of this tutorial.


JAVA INSTALLATION

We installed latest JDK from http://java.sun.com/javase/downloads/index.jsp .

Use uname -a to see if you need to download a 64 bits version.

Went to root/tmp folder for downloads:
cd /root/tmp

We got Java SE Development Kit, JDK 6 Update 13. We selected linux multilanguage, right clicked > properties on the jdk-6u13-linux-i586-rpm.bin and downloaded it with wget url on the server. It downloaded with a big name with parameters (ls to see after download). We use WinSCP so we right clicked, refreshed from there and then renamed the new file that showed up in the root home directory.
You can also rename it from shell. Make sure you use mv “old_long_name” new_name for the long name as it uses special characters.

Make sure you install JDK and not JRE.

Made it executable and executed it:

chmod a+x jdk-6u13-linux-i586-rpm.bin
./jdk-6u13-linux-i586-rpm.bin

Press space or enter to scroll terms and when it asks you type yes and hit enter.
If needed confirm Java DB update, yes ENTER.

We installed it on multiple servers and had to change some shortcuts on ones that already had an older java, so it runs the new one. Usually if preinstalled it’s located in a java or jdk folder in /usr or /usr/local .

Make sure  the shortcuts in /usr/local point to the new locations (/usr/local/jdk to /usr/java/jdk1.6.0_14 and /usr/local/jre to /usr/java/jdk1.6.0_14/jre) .
ln -s /usr/java/latest /usr/local/jdk
ln -s /usr/java/latest/jre /usr/local/jre

Also /usr/bin/java shortcut should point to /usr/java/latest (not /etc/alternatives/java):
rm /usr/bin/java
ln -s /usr/java/latest/bin/java /usr/bin/java

export JAVA_HOME=/usr/java/latest/

Make sure this is the one used if you also have older versions installed:
java –version


ANT INSTALLATION

Downloaded ant (can be done from any mirror – see http://ant.apache.org/bindownload.cgi), unpacked it, moved it to a good location and added variable, shortcut. 

Get ANT

wget http://www.apache.org/dist/ant/binaries/apache-ant-1.8.1-bin.tar.gz
tar zxvf apache-ant-1.8.1-bin.tar.gz
mv apache-ant-1.8.1 /usr/local/ant

If older  ANT is preferred get latest from http://archive.apache.org/dist/ant/binaries/ .
i.e. ANT 1.7.1
wget http://www.apache.org/dist/ant/binaries/apache-ant-1.7.1-bin.tar.gz
tar zxvf apache-ant-1.7.1-bin.tar.gz
mv apache-ant-1.7.1 /usr/local/ant

Configure
export ANT_HOME=/usr/local/ant
ln -s /usr/local/ant/bin/ant /usr/local/bin/ant

Replace old ant
rm /usr/bin/ant
ln -s /usr/local/ant/bin/ant /usr/bin/ant

Checked ant version:
ant –version

If this can’t find java, make sure you run export JAVA_HOME=/usr/java/latest/.

Error: JAVA_HOME is not defined correctly.
We cannot execute /usr/local/jdk/bin/java

SUBVERSION INSTALLATION

yum install subversion

If that doesn’t work maybe this can help:

Fix: Install perl uri:
wget ftp://rpmfind.net/linux/dag/redhat/el2.1/en/i386/dag/RPMS/perl-URI-1.17-1.el2.rf.noarch.rpm
rpm –i perl-URI-1.17-1.el2.rf.noarch.rpm

Fix: This time got  “Error: Cannot retrieve repository metadata (repomd.xml) for repository: atrpms. Please verify its path and try again” .
Solution: yum –disablerepo=atrpms install subversion .

RED5 BUILD AND INSTALLATION

Then we downloaded Red5:
svn co http://red5.googlecode.com/svn/java/server/trunk red5

Update1: This downloads latest Red5. On this installation (update1) Red5 0.9 was downloaded.

If latest trunk has bugs or does not work fine with your required software you can download other versions from http://red5.googlecode.com/svn/java/server/tags/ .

Example:
svn co http://red5.googlecode.com/svn/java/server/tags/0_8_0/ red5
or
svn co http://red5.googlecode.com/svn/java/server/tags/0_9rc1/ red5

Built red5 :
cd red5
ant prepare
ant dist

On upgrade, copy webapps to new build.

cp -rf /opt/red5/dist/webapps/* /root/tmp/red5/dist/webapps/

Then rename old red5 (backup).

You could also remove sample applications if you don’t plan to use these:
rm -rf /opt/red5/dist/webapps/live
rm -rf /opt/red5/dist/webapps/vod
rm -rf /opt/red5/dist/webapps/installer
rm -rf /opt/red5/dist/webapps/root/demos
rm -rf /opt/red5/dist/webapps/root/WEB-INF

Moved Red5 from home folder:
cd ..
mv red5 /opt/red5

Started Red5:
cd /opt/red5/dist
./red5.sh > start.log &

The > start.log is to have it output the logs in the file and & is to keep it running in the background.

Verified that Red5 was running:
ps aux | grep red5
This should report a long line with java and many options and this command. Check start.log if it failed to start.

We added these lines to to /etc/rc.d/rc.local so it starts on each server start:
cd /opt/red5/dist
/opt/red5/dist/red5.sh > restart.log &
Make sure your run it from the right folder. The one in /opt/red5 will not work – you must run it from /opt/red5/dist/ .

When Red5 is running you should be able to access http://your-server-domain-or-ip:5080/ .

If it works first thing go to http://your-server:5080/installer/and install admin. Then to http://your-server:5080/admin/register.html and register an username and password. Then you can check application statistics anytime from http://your-server:5080/admin/ with server ip and the registered username, password.

RED 5 RESTART

Restart Red5 anytime you update files in the /opt/red5/dist/webapps folder – where all applications should be installed.

Usually these should work and should be used each time you add a new application.

1. Check if red5 is running:
ps aux | grep red5

2. Go to its folder and shut red5 down:
cd /opt/red5/dist
./red5-shutdown.sh

3. See if it’s still running or not:
ps aux | grep red5

4. Restart it, and also make it output the logs into a file of your choice:
./red5.sh > start.log &

5. Make sure it’s back online:
ps aux | grep red5

We also noticed that red-shutdown.sh sometimes does not close it down to allow restart when webapps are added or updated. This usually occurs when red5 freezes becasue it encounters errors like running out of memory. So we run ps aux | grep red5 to see process id (first number: PID) and then run kill process id if it’s still alive.

ALLOWING PORTS

On some systems root cannot bind ports above the early 1000′s so red5 must be run from another account.

Verify that Red5 is listening on port 5080 if you can’t get http://yourserver:5080/:
netstat -anp | grep 5080

If using iptables enable these ports:
iptables -A INPUT -p tcp -m tcp -—dport 3690 -j ACCEPT
iptables -A INPUT -p tcp -m tcp —-dport 5080 -j ACCEPT
iptables -A INPUT -p tcp -m tcp -—dport 1935 -j ACCEPT
iptables -A INPUT -p tcp -m tcp —-dport 1936 -j ACCEPT
iptables -A INPUT -p tcp -m tcp -—dport 8088 -j ACCEPT

Sometimes ports need to be configured in a hardware firewall. Contact server provider / administrator for more details about enabling ports.

This info provided by a host could also be helpful.

Please be advised that custom iptables rules should be placed in the directory listed below.
/etc/sysconfig/iptables-custom

The software firewall rule is listed as follows:
# cat /etc/sysconfig/iptables-custom/99Red5 *filter

-A INPUT -p tcp -m tcp –dport 1935 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 1936 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 5080 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 8088 -j ACCEPT

COMMIT

RED5 & VIDEOWHISPER

This was done for the installation of VideoWhisper applications. To do that just download the latest videowhisper rtmp application, unzip it on your computer and copy the videowhisper folder and all its contents to/opt/red5/dist/webapps .  As verification, check that you have a /opt/red5/dist/webapps/videowhisper/WEB-INF/ folder on your server. After copying/updating this, restart the Red5 server (as explained above) and you can install the videowhisper video conferencing / live streaming scrips to use the new rtmp application.

The Red5 VideoWhisper RTMP Application has some cool settings, like enabling access with external players / archiving of all video streams as flv files / limiting access to certain domains / setting absolute paths for live streams and recordings to be able to share videos with other applications (i.e. video sharing). Edit all these in WEB-INF/red5-web.properties and restart the Red5 server.

If we forgot to mention something here, or you have any questions about this submit your inquiries on Video Whisper Contact Page or comment below.

An alternative to doing the red5 installation yourself would be to order red5 installation .

If you don’t have the time and experience to run your own server or vps, you should use managed red5 hosting .
