Installing the Couch(DB)
In my previous post, I talked about some introductory topics regarding CouchDB. In this post I want to walk you through some of the hurdles you need to take when you want to install CouchDB on a freshly installed Ubuntu Linux 9.0.4. Now I don’t want to claim that there isn’t a simpler way for getting CouchDB up and running, which probably should be the case. I just want to put out everything I had to deal with when I tried installing the trunk version (V9.0) of CouchDB. I didn’t install the pre-packaged version (V8.02) as that would be too easy :-). Here goes …
1. Prepare your environment:
sudo aptitude install automake autoconf libtool subversion-tools help2man spidermonkey-bin build-essentialerlang erlang-manpages libicu38 libicu-dev libreadline5-dev checkinstall libmozjs-dev wget
sudo apt-get install libcurl4-gnutls-dev
2. Create a new user for running CouchDB:
sudo adduser –no-create-home –disabled-password –disabled-login couchdb
3. Get the latest source code from the trunk:
svn co http://svn.apache.org/repos/asf/couchdb/trunk couchdb
4. Build and install:?
./configure –bindir=/usr/bin –sbindir=/usr/sbin –localstatedir=/var –sysconfdir=/etc
make && sudo make install
5. Make the CouchDB user, that was created in step 2, the owner of the installed binaries:
sudo chown couchdb:couchdb -R? /var/lib/couchdb /var/log/couchdb
6. Now we’re all set to launch the CouchDB server:
sudo -i -u couchdb couchdb
If everything goes well, you should see something similar as the following output:
sudo: unable to change directory to /home/couchdb: No such file
Apache CouchDB 0.10.0a780291 (LogLevel=info) is starting.
Apache CouchDB has started. Time to relax.
[info] [<0.1.0>] Apache CouchDB has started.
7. In order to verify that CouchDB is up and running, you can install cURL and issue the following command:
sudo apt-get install curl
This should give you the following response:
8. [Optional] Register? CouchDB as a service:
sudo update-rc.d couchdb defaults
sudo /etc/init.d/couchdb start
So far in our setup, we can only access CouchDB from the local Linux (virtual) machine. My personal goal was to access CouchDB from a sample application that I’m developing on another Windows virtual machine that hosts my development environment. In order to accomplish that, some additional steps need to be taken:
1. Open the correct port on the firewall when enabled. You can do this by issuing the following:
sudo iptables -I INPUT 3 -p tcp –dport 5984 -j ACCEPT
2. Go to the local.ini file in the /etc/couchdb/ directory and uncomment the line that specifies the bind_address setting (in the httpd section) by removing the semicolon in front of it (figuring out this one kept me busy for quite some time 😉 ).
3. Change the bind_address setting so that it now specifies 0.0.0.0 instead of 127.0.0.0. After restarting CouchDB, it will now bind to all addresses.
4. We’re done.
As I mentioned before, I’m quite a Linux rookie so it was definitely a challenge figuring this out.
Now I need some relaxation. Till next time.
