CouchDB on Gumstix with OpenEmbedded
Goal
Gumstix, like BeagleBoard, is an embedded platform. I want to run CouchDB on it.
Building CouchDB on Gumstix
STATUS:
- Native build: Works!
- Cross-compile build: haven't tested. See the resources section at the bottom. Looks "simple" enough.
Native Installation
We'll start by building on ARM and later move to a bitbake recipe (if it's possible for me to create one).
opkg install task-sdk-native
nspr sudo opkg install libgnutls26 icu icu-dev curl curl-dev
erlang
USER=root
GUMSTIX=192.168.1.10
cd ~/overo-oe
bitbake erlang
scp ./tmp/deploy/glibc/ipk/armv7a/erlang-libs_*_armv7a.ipk ${USER}@${GUMSTIX}:~/
scp ./tmp/deploy/glibc/ipk/armv7a/erlang_*_armv7a.ipk ${USER}@${GUMSTIX}:~/
On the overo
sudo opkg install ~/erlang*
CouchDB
About 15 mins. Installs executable to /usr/local
wget http://www.ecoficial.com/apachemirror//couchdb/1.0.1/apache-couchdb-1.0.1.tar.gz
tar xf apache-couchdb-1.0.1.tar.gz
cd apache-couchdb-1.0.1
./configure
make && sudo make install
Then configuration
cd ~/
sudo su -
adduser couchdb
vim /etc/passwd
chown couchdb:couchdb /usr/local/var/lib/couchdb/
chown -R couchdb: /usr/local/var/*/couchdb /usr/local/etc/couchdb
chmod 0770 /usr/local/var/*/couchdb
chmod 664 /usr/local/etc/couchdb/*.ini
chmod 775 /usr/local/etc/couchdb/*.d
cd /etc/init.d
ln -s /usr/local/etc/init.d/couchdb couchdb
update-rc.d couchdb defaults
/etc/init.d/couchdb start
ping -c 1 127.0.0.1 # just to make sure that you haven't misconfigured `/etc/networking/interfaces` ... I have
curl http://127.0.0.1:5984/
# {"couchdb":"Welcome","version":"1.0.1"}
# run test suite in firefox at http://127.0.0.1:5984/_utils/couch_tests.html?script/couch_tests.js
Admin Party!!!!
Yes, party because it's working.
Yes, go into the browser and set a password.

Replication
I also have an account on couchone.com which uses http authentication.
To replicate the database I:
- create a new database on my gumstix
- secure it by selecting both one admin and one reader
- replicate it by entering the remote as
http://USER:PASSWORD@mydb.couchone.com - selecting the name of my local database

Appendix
nspr is not available through the Angstrom repository. It can be bitbaked.
