Remove Lucid/ppa instructions from SAIO guide
Lucid won't EOL until May of 2014; but I stopped trusting that ppa a long time ago. Besides with the requires for dnspython and mock where they're at you almost can't install swift from source on any stock distro and expect tests to pass with system packages - so we're looking at pypi for depends regardless. While I'm in there: * more explanation of <your-user-name> and a helpful find/sed for configs * group the "setup ~/.bashrc" stuff with the "setup ~/bin" stuff * some updates/fixes from my experience installing on CentOS * remove region warnings from remakerings Change-Id: Ie2e6b06959ab699d853e07e5b7e8cda7036a44fe

This section documents setting up a virtual machine for doing Swift development.
|
||||
The virtual machine will emulate running a four node Swift cluster.
|
||||
|
||||
* Get either Ubuntu 12.04 LTS (Precise Pangolin) or Ubuntu 10.04 LTS (Lucid Lynx) server image.
|
||||
* Get an Ubuntu 12.04 LTS (Precise Pangolin) server image or try something Fedora/CentOS.
|
||||
|
||||
* Create guest virtual machine from the Ubuntu image.

* Create guest virtual machine from the image.

Additional information about setting up a Swift development snapshot on other distributions is
|
||||
available on the wiki at http://wiki.openstack.org/SAIOInstructions.

||||
Installing dependencies and the core code
|
||||
-----------------------------------------
|
||||
* On Ubuntu,
|
||||
----------------------------
|
||||
What's in a <your-user-name>
|
||||
----------------------------
|
||||
|
||||
Much of the configuration described in this guide requires escalated root
|
||||
privileges; however, we assume that administrator logs in an unprivileged
|
||||
user. Swift processes also run under a separate user and group, set by
|
||||
configuration option, and refered as <your-user-name>:<your-group-name>.
|
||||
The default user is `swift`, which may not exist on your system.
|
||||
|
||||
Perform the following commands as root.
|
||||
|
||||
-----------------------
|
||||
Installing dependencies
|
||||
-----------------------
|
||||
|
||||
* On apt based systems,
|
||||
|
||||
#. `apt-get install python-software-properties`
|
||||
#. `add-apt-repository ppa:swift-core/release`
|
||||
#. `apt-get update`
|
||||
#. `apt-get install curl gcc git-core memcached python-coverage python-dev
|
||||
python-nose python-setuptools python-simplejson python-xattr sqlite3
|
||||
xfsprogs python-eventlet python-greenlet python-pastedeploy
|
||||
python-netifaces python-pip`
|
||||
#. `pip install mock`
|
||||
#. `pip install dnspython`
|
||||
#. Install anything else you want, like screen, ssh, vim, etc.
|
||||
#. `apt-get install curl gcc memcached rsync sqlite3 xfsprogs git-core python-setuptools`
|
||||
#. `apt-get install python-coverage python-dev python-nose python-simplejson
|
||||
python-xattr python-eventlet python-greenlet python-pastedeploy
|
||||
python-netifaces python-pip python-dnspython python-mock`
|
||||
|
||||
* On Fedora,
|
||||
* On yum based systems,
|
||||
|
||||
#. `yum install xinetd rsync`
|
||||
#. `yum install memcached`
|
||||
#. `yum install python-netifaces python-nose python-mock python-dns`
|
||||
#. `yum install git gcc`
|
||||
#. `yum install curl gcc memcached rsync sqlite xfsprogs git-core xinetd python-setuptools`
|
||||
#. `yum install python-coverage python-devel python-nose python-simplejson
|
||||
python-xattr python-eventlet python-greenlet python-pastedeploy
|
||||
python-netifaces python-pip python-dnspython python-mock`
|
||||
|
||||
This installs all necessary dependencies, and you could use your guest user
|
||||
or root for starting process. But you must first config it correctly
|
||||
(`user = <your-user-name>`) in object-server.conf or proxy.conf, and then use
|
||||
it to be used in every place where this manual calls for
|
||||
`<your-user-name>:<your-group-name>`.
|
||||
|
||||
Ensure that you are installing the version of Swift that corresponds to
|
||||
this document. If not, enable the correct update repositories.
|
||||
This installs necessary system dependencies; and *most* of the python
|
||||
dependencies. Later in the process setuptools/distribute or pip will
|
||||
install and/or upgrade some other stuff - it's getting harder to avoid.
|
||||
You can also install anything else you want, like screen, ssh, vim, etc.
|
||||
|
||||
Next, choose either :ref:`partition-section` or :ref:`loopback-section`.

Starting memcached
|
||||
------------------
|
||||
|
||||
On Fedora, make sure that memcached runs, running this if necessary:
|
||||
On non-Ubuntu distros you need to ensure memcached is running:
|
||||
|
||||
* `service memcached start`
|
||||
* `chkconfig memcached on`
|
||||
|
||||
or:
|
||||
|
||||
* `systemctl enable memcached.service`
|
||||
* `systemctl start memcached.service`
|
||||
|
||||
If this is not done, tokens of tempauth expire immediately and accessing
|
||||
Swift with curl becomes impossible.
|
||||
The tempauth middleware stores tokens in memcached. If memcached is not
|
||||
running, tokens cannot be validated, and accessing Swift becomes impossible.
