Apache CouchDB README.Unix
==========================
A high-level guide to Unix-like systems, inc. Mac OS X and Ubuntu.
Dependencies
------------
You will need the following installed:
* Erlang OTP (>=R13B2) (http://erlang.org/)
* ICU (http://icu.sourceforge.net/)
* OpenSSL (http://www.openssl.org/)
* Mozilla SpiderMonkey (1.8) (http://www.mozilla.org/js/spidermonkey/)
* libcurl (http://curl.haxx.se/libcurl/)
* GNU Make (http://www.gnu.org/software/make/)
* GNU Compiler Collection (http://gcc.gnu.org/)
It is recommended that you install Erlang OTP R12B-5 or above where possible.
Ubuntu
~~~~~~
See
http://wiki.apache.org/couchdb/Installing_on_Ubuntu
for updated instructions on how to install on Ubuntu.
Debian-based Systems
~~~~~~~~~~~~~~~~~~~~
You can install the build tools by running:
sudo apt-get install build-essential
You can install the other dependencies by running:
sudo apt-get install erlang libicu-dev libmozjs-dev libcurl4-openssl-dev
Be sure to update the version numbers to match your system's available packages.
Mac OS X
~~~~~~~~
You can install the build tools by running:
open /Applications/Installers/Xcode\ Tools/XcodeTools.mpkg
You can install the other dependencies by running:
sudo port install icu erlang spidermonkey curl
You will need MacPorts installed to use the `port` command.
Installing
----------
Once you have satisfied the dependencies you should run:
./configure
This script will configure CouchDB to be installed into `/usr/local` by default.
If you wish to customise the installation, pass `--help` to this script.
If everything was successful you should see the following message:
You have configured Apache CouchDB, time to relax.
Relax.
To install CouchDB you should run:
make && sudo make install
You only need to use `sudo` if you're installing into a system directory.
Try `gmake` if `make` is giving you any problems.
If everything was successful you should see the following message:
You have installed Apache CouchDB, time to relax.
Relax.
First Run
---------
You can start the CouchDB server by running:
sudo -i -u couchdb couchdb
This uses the `sudo` command to run the `couchdb` command as the `couchdb` user.
When CouchDB starts it should eventually display the following message:
Apache CouchDB has started, time to relax.
Relax.
To check that everything has worked, point your web browser to:
http://127.0.0.1:5984/_utils/index.html
From here you should run the test suite.
Security Considerations
-----------------------
You should create a special `couchdb` user for CouchDB.
On many Unix-like systems you can run:
adduser --system \
--home /usr/local/var/lib/couchdb \
--no-create-home \
--shell /bin/bash \
--group --gecos \
"CouchDB Administrator" couchdb
On Mac OS X you can use the Workgroup Manager to create users:
http://www.apple.com/support/downloads/serveradmintools1047.html
You must make sure that:
* The user has a working POSIX shell
* The user's home directory is `/usr/local/var/lib/couchdb`
You can test this by:
* Trying to log in as the `couchdb` user
* Running `pwd` and checking the present working directory
Change the ownership of the CouchDB directories by running:
chown -R couchdb:couchdb /usr/local/etc/couchdb
chown -R couchdb:couchdb /usr/local/var/lib/couchdb
chown -R couchdb:couchdb /usr/local/var/log/couchdb
chown -R couchdb:couchdb /usr/local/var/run/couchdb
Change the permission of the CouchDB directories by running:
chmod 0770 /usr/local/etc/couchdb
chmod 0770 /usr/local/var/lib/couchdb
chmod 0770 /usr/local/var/log/couchdb
chmod 0770 /usr/local/var/run/couchdb
Running as a Daemon
-------------------
SysV/BSD-style Systems
~~~~~~~~~~~~~~~~~~~~~~
You can use the `couchdb` init script to control the CouchDB daemon.
On SysV-style systems, the init script will be installed into:
/usr/local/etc/init.d
On BSD-style systems, the init script will be installed into:
/usr/local/etc/rc.d
We use the `[init.d|rc.d]` notation to refer to both of these directories.
You can control the CouchDB daemon by running:
/usr/local/etc/[init.d|rc.d]/couchdb [start|stop|restart|status]
If you wish to configure how the init script works, you can edit:
/usr/local/etc/default/couchdb
Comment out the `COUCHDB_USER` setting if you're running as a non-superuser.
To start the daemon on boot, copy the init script to:
/etc/[init.d|rc.d]
You should then configure your system to run the init script automatically.
You may be able to run:
sudo update-rc.d couchdb defaults
If this fails, consult your system documentation for more information.
A `logrotate` configuration is installed into:
/usr/local/etc/logrotate.d/couchdb
Consult your `logrotate` documentation for more information.
It is critical that the CouchDB logs are rotated so as not to fill your disk.
Mac OS X
~~~~~~~~
You can use the `launchctl` command to control the CouchDB daemon.
You can load the configuration by running:
sudo launchctl load \
/usr/local/Library/LaunchDaemons/org.apache.couchdb.plist
You can stop the CouchDB daemon by running:
sudo launchctl unload \
/usr/local/Library/LaunchDaemons/org.apache.couchdb.plist
You can start CouchDB by running:
sudo launchctl start org.apache.couchdb
You can restart CouchDB by running:
sudo launchctl stop org.apache.couchdb
You can edit the launchd configuration by running:
open /usr/local/Library/LaunchDaemons/org.apache.couchdb.plist
To start the daemon on boot, copy the configuration file to:
/Library/LaunchDaemons
Consult your system documentation for more information.
