Install couchdb 0.9.0 and Erlang R13B from sources on ubuntu Jaunty 9.04

I wanted to play with CouchDB 0.9.0 on Ubuntu Jaunty, and to do this I had to compile it from sources, and to be in sync with CouchDBX I compiled as well erlang 13B.
This is the transcript of what I did.

Erlang

Dependencies

install some dev packages

sudo apt-get install build-essential m4 libssl-dev libncurses-dev

note: if you need support for odbc, jinterface or wx you need to install their dependencies

Compiling

wget http://erlang.org/download/otp_src_R13B.tar.gz
tar zxf otp_src_R13B.tar.gz
cd otp_src_R13B
./configure
make
sudo make install

CouchDB

Dependencies

sudo apt-get install libcurl4-openssl-dev libicu-dev libmozjs-dev

Compiling

wget http://apache.mirroring.de/couchdb/0.9.0/apache-couchdb-0.9.0.tar.gz
tar zxf apache-couchdb-0.9.0.tar.gz
cd apache-couchdb-0.9.0
./configure --sharedstatedir=/var/local --localstatedir=/var/local
make
sudo make install

System configuration

You need to create a user for couchdb

sudo useradd -d /var/local/lib/couchdb couchdb
sudo chown couchdb. /var/local/lib/couchdb
sudo chmod 750 /var/local/lib/couchdb

I prefer to have the logs in /var/log/couchdb and the pid in /var/run/couch.pid so let's edit the configuration file
in /usr/local/etc/couchdb/local.ini
edit the file so the log section looks as follows

[log]
file = /var/log/couchdb/couch.log

to edit the pid location we need to edit the file in /usr/local/etc/default/couchdb
this is how my file looks like

COUCHDB_USER=couchdb
COUCHDB_STDOUT_FILE=/dev/null
COUCHDB_STDERR_FILE=/dev/null
COUCHDB_PID_FILE=/var/run/couchdb.pid
COUCHDB_RESPAWN_TIMEOUT=5
COUCHDB_OPTIONS=

It's time to setup the init.d script

sudo cp -v /usr/local/etc/init.d/couchdb /etc/init.d/couchdb

we need to amend/etc/init.d/couchdb to set the permission of the pid file when the daemon starts

you need to find the section

    if test -n "$COUCHDB_PID_FILE"; then
        command="$command -p $COUCHDB_PID_FILE"
    fi

and change it to

    if test -n "$COUCHDB_PID_FILE"; then
        touch $COUCHDB_PID_FILE
        chown $COUCHDB_USER. $COUCHDB_PID_FILE
        command="$command -p $COUCHDB_PID_FILE"
    fi

again we need to edit /etc/init.d/couchdb because the stop command won't work as it is
you need to find the "stop_couchdb" function at the line

    command="$COUCHDB -d"

and change it to

    command="$COUCHDB -d"
    if test -n "$COUCHDB_PID_FILE"; then
        command="$command -p $COUCHDB_PID_FILE"
    fi

As a last step we want to create the directory for the logs

sudo mkdir /var/log/couchdb
sudo chown couchdb. /var/log/couchdb

And consequently set the log rotation in /etc/logrotate.d/couchdb

/var/log/couchdb/*.log {
        daily
        missingok
        rotate 52
        compress
        delaycompress
        notifempty
        create 640 couchdb adm
        sharedscripts
        postrotate
                [ ! -f /var/run/couchdb.pid ] || kill -USR1 `cat /var/run/couchdb.pid`
        endscript
}

And now is time to have some fun

/etc/init.d/couchdb start
curl 127.0.0.1:5984
curl 127.0.0.1:5984/test
curl -X PUT 127.0.0.1:5984/test
curl 127.0.0.1:5984/test
curl 127.0.0.1:5984/test/baz
curl -X PUT -d '{"foo":"bar"}' 127.0.0.1:5984/test/baz
curl 127.0.0.1:5984/test/baz

Note: I just finished checking this installation process with the release candidate of couchdb 0.9.1 and it works fine
