Instructions for compiling and running the EtherPad open source release

How we can install Etherpad on Open SUSE Linux?

I just want to help you out… If you want to pay me nothing that is fine too! 😉

Here are some simple steps to install Etherpad on Open SUSE Linux…..

SUSE Linux is different from RedHat, CentOS or Ubuntu. General Package Managers / Setup Tool won’t work on SUSE, It support Zypper or YaST.

First check your server architecture

# uname -a

# cd /usr/local

Java 1.6 (tested with 1.6.0_20)
Scala 2.7 (tested with 2.7.7)
MySQL Server 5.1 (tested with 5.1.59)
mysql-connector-java (tested with 5.1.18)

Create username ‘etherpad’ with password ‘password’

# useradd -r -m etherpad
# passwd etherpad

Install Java

# uname -a
I am using 32-bit here…
# wget
# sh jdk-6u20-linux-i586-rpm.bin

# java -version

Install fastjar

# zypper install fastjar
# yast –install fastjar
# yast2 –install fastjar

Download Scala

# wget
# tar xvzf

Install MySQL

# zypper install mysql-server
# service mysqld start
# chkconfig mysqld on

Download MySQL Java Connector


# zypper install mysql-connector-java


# wget
# tar xvzf mysql-connector-java-5.1.18.tar.gz

Install MER­CU­R­IAL .. OR GIT

# zypper install mercurial

# zypper install git

Make sure port 9000 must be open on IPTABLES / Firewall

# /etc/sysconfig/iptables

-A RH-Firewall-1-INPUT -p tcp -m state –state NEW -m tcp –dport 9000 -j ACCEPT

Various scripts make assumptions about environment variables:

JAVA should be set to the java executable.
JAVA_HOME should be set to the main jdk directory.
SCALA should be set to the scala executable.
SCALA_HOME should be set to the main scala distribution directory.
PATH should contain $JAVA, $SCALA, and mysql
MYSQL_CONNECTOR_JAR should be set to the mysql-connector JAR file included in the mysql-connector download.
For example, this sets up the environment on my machine:

# touch myENV
# vi myENV

export JAVA_HOME=/usr/java/jdk1.6.0_20/
export JAVA=$JAVA_HOME/bin/java
export SCALA_HOME=/usr/local/scala/
export SCALA=$SCALA_HOME/bin/scala
export MYSQL_CONNECTOR_JAR=/usr/local/mysqlconnector/mysql-connector-java-5.1.18-bin.jar

# cat myENV >> /etc/profile

Download EtherPad

# hg clone etherpad

Some Changes in etherpad source for your server…


# cd /usr/local
# cd etherpad/trunk/etherpad
# cp etc/ data/











Database Setup
The scripts assume mysqld is running on localhost. Once mysqld is running, you can set up the etherpad database by running the following command inside ajcode/etherpad/.

# bin/
This will create a database called “etherpad” with the password “password”, and grant privileges to the user “etherpad”.

All the tables will be set up the first time etherpad is run.

EtherPad compiles all its Java and Scala libraries into a single JAR. To build this jar, you can run the following command inside ajcode/etherpad/.

# bin/
If you modify anything in ajcode/infrastructure, you will most likely need to kill the server, rebuild the jar, and re-launch the server before your change takes effect.

Code inside ajcode/etherpad/src can be modified while the server is running, and the changes will automatically get picked up.

To run the etherpad web server, execute the following command inside ajcode/etherpad/.

# bin/
The first time you run this, it should print out lots of messages about database migrations and finally print:

HTTP server listening on http://youdomain:9000/
At this point, you should be able to visit http://youdomain:9000/ in your web browser and create a new pad.

Thanks to Pauleira!

If you have error related to JVM

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

Fix using

# export _JAVA_OPTIONS=’-Xms32m -Xmx56m -Xss128k -XX:PermSize=32m -XX:MaxPermSize=64m’

Red5 figure out audio/video out of sync issue

Hits: 4232  

I had worked Red5 WebCam application that lets users to record video clips from their webcams. The users could talk while they record clips.

I was using PHP with Zend Gdata for uploading recorded video clips to YouTube. But I had issue in FLV files generated by Red5 server, the clip’s audio / video content was out of sync. 🙁

Code to upload Red5 FLV to YouTube

Then after few searches I got… FFMpeg might be a good option to solve this issue to convert clip from FLV to MP4. 🙂


I have to add -itsoffset 00:00:01.16 before the -i, because flash player prompts user to allow or deny webcam access during the process the video begins to record. these are seconds of recording where nothing is recorded. To audio video sync add the itsoffset that tell ffmpeg to wait a second before it starts the the transcoding.

FFMpeg syntax to sync the audio and video using MP4 file:



$myVideoEntry = new Zend_Gdata_YouTube_VideoEntry();

$file= 'tmp/'.$fileName.".flv";

// convert FLV file to MP4 using -vcodec libx264

$mp4file= 'tmp/'.$fileName.".mp4"; 

exec("/usr/bin/ffmpeg -y -itsoffset 00:00:01.166000 -i ".$file." -s 640x480 -y -strict experimental -acodec aac -ab 128k -ac 2 -ar 48000 -vcodec libx264 -r 24 -g 48 -b 520000 -threads 64 ".$mp4file);

$file = $mp4file;

$file = realpath($file);  



Other Command
# /usr/bin/ffmpeg -i “svnlabs.flv” -s 640×480 -y -strict experimental -acodec aac -ab 128k -ac 2 -ar 48000 -vcodec libx264 -vpre medium -vpre ipod640 -r 24 -g 48 -b 520000 -threads 64 “svnlabs.mp4”
