Etherpad

Revision 12 as of 2010-01-29 14:53:48

Clear message

Install packages

Install pre-requisite packages for getting and building Etherpad.

sudo apt-get install sun-java6-jdk scala mysql-server mysql-client libmysql-java mercurial

Etherpad will not build or run with openjdk-6-jdk or openjdk-6-jre. It also is best to use Sun's jar since fastjar seems to have some issues.

Get Etherpad code

There are no releases of Etherpad at the moment, so we grab directly from mercurial.

hg clone https://etherpad.googlecode.com/hg/ etherpad

If you are running this command from behind an office firewall, you might run into a bug in Python for HTTPS from behind a proxy (http://bugs.python.org/issue1424152). Clone from the http URL instead.

hg clone http://etherpad.googlecode.com/hg/ etherpad

You will need to patch the etherpad code to build on Ubuntu:

(As of Dec. 23, 2009 the patching instructions above are either incomplete or do not provide any explanation on what to do. Typing the first command directly into the command line produces a "not found" error. Please revise these instructions to be more clear in a step-by-step fashion rather than assuming a user should know what to do.) Yes and Update would be nice Smile :)

Configure Environment

Configure MySQL

Set the variable "mysql" in the db setup script, to the name of your mysql client executable.

Run the db setup script.

$ cd trunk/etherpad
$ sudo bin/setup-mysql-db.sh

Note if you had setup a password for the root account on the mysql server, then this won't work directly. You can edit the setup-mysql-db.sh as needed to fix this. For example

- echo "create database ${db};" | ${mysql} -u root
+ echo "create database ${db};" | ${mysql} --user=root --password=secret
#and same for the other instances of ${mysql}

Compiling Etherpad

From trunk/etherpad:

$ bin/rebuildjar.sh

Running Etherpad

$ bin/run-local.sh
