CouchDB on Amazon EC2


https://github.com/iriscouch/build-couchdb (from http://wiki.apache.org/couchdb/Installing_on_Ubuntu)

  • Setup new instance: Ubuntu 11.10
  • ssh to new box
  • run the following to build couchdb from source (packages available via "sudo aptitude install couchdb" are too old):
sudo apt-get install git
sudo apt-get install make gcc zlib1g-dev libssl-dev rake
git clone git://github.com/iriscouch/build-couchdb
cd build-couchdb
git submodule init
git submodule update
rake
couchdb

ubuntu@ip-10-128-141-191:~/build-couchdb$ couchdb
Apache CouchDB 1.0.1 (LogLevel=info) is starting.

Alternatives

http://wiki.apache.org/couchdb/Getting_started_with_Amazon_EC2

  • sudo apt-get update && sudo apt-get -y upgrade
  • sudo apt-get install erlang libmozjs-dev libicu-dev libcurl4-gnutls-dev make subversion automake autoconf libtool help2man
  • Fetch, build, and run CouchDB:
    • svn checkout http://svn.apache.org/repos/asf/couchdb/trunk couchdb
    • cd couchdb
    • ./bootstrap
    • ./configure
    • ./configure
    • make && sudo make install
    • sudo adduser --system --home /usr/local/var/lib/couchdb --no-create-home --shell /bin/bash --group --gecos 'CouchDB account' couchdb
    • sudo chown -R couchdb.couchdb /usr/local/var/{lib,log}/couchdb
    • (Optional) Enable direct web access. NOTE: This step makes your CouchDB instance available for everyone. See the FaQ for some (but not all) security options.
      • sudo vim /usr/local/etc/couchdb/local.ini 
      • Search for "bind_address", uncomment it, and change it to 0.0.0.0
      • Save and exit
    • (Alternative option) Set up port forwarding to access your DB, for example with SSH.
      • ssh -L 5984:localhost:5984 -l ubuntu <public DNS name>
      • Leave that session open as long as you need the proxy to work
      • Your new DB URL will be http://127.0.0.1:5984/ instead.
    • sudo -i -u couchdb couchdb 
    • Test it by going to http://<public dns name>:5984/_utils/
