This section documents setting up a virtual machine for doing Swift development. The virtual machine will emulate running a four node Swift cluster.
Additional information about setting up a Swift development snapshot on other distributions is available on the wiki at http://wiki.openstack.org/SAIOInstructions.
Much of the configuration described in this guide requires escalated administrator (root) privileges; however, we assume that administrator logs in as an unprivileged user and can use sudo to run privileged commands.
Swift processes also run under a separate user and group, set by configuration option, and referenced as <your-user-name>:<your-group-name>. The default user is swift, which may not exist on your system. These instructions are intended to allow a developer to use his/her username for <your-user-name>:<your-group-name>.
On apt based systems:
sudo apt-get update
sudo apt-get install curl gcc memcached rsync sqlite3 xfsprogs \
git-core libffi-dev python-setuptools
sudo 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 yum based systems:
sudo yum update
sudo yum install curl gcc memcached rsync sqlite xfsprogs git-core \
libffi-devel xinetd python-setuptools \
python-coverage python-devel python-nose \
python-simplejson pyxattr python-eventlet \
python-greenlet python-paste-deploy \
python-netifaces python-pip python-dns \
python-mock
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 Using a partition for storage or Using a loopback device for storage.
If you are going to use a separate partition for Swift data, be sure to add another device when creating the VM, and follow these instructions:
Set up a single partition:
sudo fdisk /dev/sdb sudo mkfs.xfs /dev/sdb1Edit /etc/fstab and add:
/dev/sdb1 /mnt/sdb1 xfs noatime,nodiratime,nobarrier,logbufs=8 0 0Create the mount point and the individualized links:
sudo mkdir /mnt/sdb1 sudo mount /mnt/sdb1 sudo mkdir /mnt/sdb1/1 /mnt/sdb1/2 /mnt/sdb1/3 /mnt/sdb1/4 sudo chown ${USER}:${USER} /mnt/sdb1/* sudo mkdir /srv for x in {1..4}; do sudo ln -s /mnt/sdb1/$x /srv/$x; done sudo mkdir -p /srv/1/node/sdb1 /srv/2/node/sdb2 /srv/3/node/sdb3 \ /srv/4/node/sdb4 /var/run/swift sudo chown -R ${USER}:${USER} /var/run/swift # **Make sure to include the trailing slash after /srv/$x/** for x in {1..4}; do sudo chown -R ${USER}:${USER} /srv/$x/; doneNext, skip to Common Post-Device Setup.
If you want to use a loopback device instead of another partition, follow these instructions:
Create the file for the loopback device:
sudo mkdir /srv sudo truncate -s 1GB /srv/swift-disk sudo mkfs.xfs /srv/swift-diskModify size specified in the truncate command to make a larger or smaller partition as needed.
Edit /etc/fstab and add:
/srv/swift-disk /mnt/sdb1 xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0Create the mount point and the individualized links:
sudo mkdir /mnt/sdb1 sudo mount /mnt/sdb1 sudo mkdir /mnt/sdb1/1 /mnt/sdb1/2 /mnt/sdb1/3 /mnt/sdb1/4 sudo chown ${USER}:${USER} /mnt/sdb1/* for x in {1..4}; do sudo ln -s /mnt/sdb1/$x /srv/$x; done sudo mkdir -p /srv/1/node/sdb1 /srv/2/node/sdb2 /srv/3/node/sdb3 /srv/4/node/sdb4 /var/run/swift sudo chown -R ${USER}:${USER} /var/run/swift # **Make sure to include the trailing slash after /srv/$x/** for x in {1..4}; do sudo chown -R ${USER}:${USER} /srv/$x/; done
Add the following lines to /etc/rc.local (before the exit 0):
mkdir -p /var/cache/swift /var/cache/swift2 /var/cache/swift3 /var/cache/swift4
chown <your-user-name>:<your-group-name> /var/cache/swift*
mkdir -p /var/run/swift
chown <your-user-name>:<your-group-name> /var/run/swift
Note that on some systems you might have to create /etc/rc.local.
On Fedora 19 or later, you need to place these in /etc/rc.d/rc.local.
Check out the python-swiftclient repo:
cd $HOME; git clone https://github.com/openstack/python-swiftclient.gitBuild a development installation of python-swiftclient:
cd $HOME/python-swiftclient; sudo python setup.py develop; cd -Check out the swift repo:
git clone https://github.com/openstack/swift.gitBuild a development installation of swift:

sudo pip install -U xattrInstall swift’s test dependencies:
sudo pip install -r swift/test-requirements.txt
Create /etc/rsyncd.conf:
sudo cp $HOME/swift/doc/saio/rsyncd.conf /etc/ sudo sed -i "s/<your-user-name>/${USER}/" /etc/rsyncd.confHere is the default rsyncd.conf file contents maintained in the repo that is copied and fixed up above:
uid = <your-user-name> gid = <your-user-name> log file = /var/log/rsyncd.log pid file = /var/run/rsyncd.pid address = 127.0.0.1 [account6012] max connections = 25 path = /srv/1/node/ read only = false lock file = /var/lock/account6012.lock [account6022] max connections = 25 path = /srv/2/node/ read only = false lock file = /var/lock/account6022.lock [account6032] max connections = 25 path = /srv/3/node/ read only = false lock file = /var/lock/account6032.lock [account6042] max connections = 25 path = /srv/4/node/ read only = false lock file = /var/lock/account6042.lock [container6011] max connections = 25 path = /srv/1/node/ read only = false lock file = /var/lock/container6011.lock [container6021] max connections = 25 path = /srv/2/node/ read only = false lock file = /var/lock/container6021.lock [container6031] max connections = 25 path = /srv/3/node/ read only = false lock file = /var/lock/container6031.lock [container6041] max connections = 25 path = /srv/4/node/ read only = false lock file = /var/lock/container6041.lock [object6010] max connections = 25 path = /srv/1/node/ read only = false lock file = /var/lock/object6010.lock [object6020] max connections = 25 path = /srv/2/node/ read only = false lock file = /var/lock/object6020.lock [object6030] max connections = 25 path = /srv/3/node/ read only = false lock file = /var/lock/object6030.lock [object6040] max connections = 25 path = /srv/4/node/ read only = false lock file = /var/lock/object6040.lockOn Ubuntu, edit the following line in /etc/default/rsync:
RSYNC_ENABLE=trueOn Fedora, edit the following line in /etc/xinetd.d/rsync:
disable = noOne might have to create the above files to perform the edits.
On platforms with SELinux in Enforcing mode, either set to Permissive:
sudo setenforce PermissiveOr just allow rsync full access:
sudo setsebool -P rsync_full_access 1Start the rsync daemon
On Ubuntu, run:
sudo service rsync restartOn Fedora, run:
sudo systemctl restart xinetd.service sudo systemctl enable rsyncd.service sudo systemctl start rsyncd.serviceOn other xinetd based systems simply run:
sudo service xinetd restartVerify rsync is accepting connections for all servers:
rsync rsync://pub@localhost/You should see the following output from the above command:
account6012 account6022 account6032 account6042 container6011 container6021 container6031 container6041 object6010 object6020 object6030 object6040
On non-Ubuntu distros you need to ensure memcached is running:
sudo service memcached start
sudo chkconfig memcached on
or:
sudo systemctl enable memcached.service
sudo systemctl start memcached.service
The tempauth middleware stores tokens in memcached. If memcached is not running, tokens cannot be validated, and accessing Swift becomes impossible.
Install the swift rsyslogd configuration:
sudo cp $HOME/swift/doc/saio/rsyslog.d/10-swift.conf /etc/rsyslog.d/Be sure to review that conf file to determine if you want all the logs in one file vs. all the logs separated out, and if you want hourly logs for stats processing. For convenience, we provide its default contents below:
# Uncomment the following to have a log containing all logs together #local1,local2,local3,local4,local5.* /var/log/swift/all.log # Uncomment the following to have hourly proxy logs for stats processing #$template HourlyProxyLog,"/var/log/swift/hourly/%$YEAR%%$MONTH%%$DAY%%$HOUR%" #local1.*;local1.!notice ?HourlyProxyLog local1.*;local1.!notice /var/log/swift/proxy.log local1.notice /var/log/swift/proxy.error local1.* ~ local2.*;local2.!notice /var/log/swift/storage1.log local2.notice /var/log/swift/storage1.error local2.* ~ local3.*;local3.!notice /var/log/swift/storage2.log local3.notice /var/log/swift/storage2.error local3.* ~ local4.*;local4.!notice /var/log/swift/storage3.log local4.notice /var/log/swift/storage3.error local4.* ~ local5.*;local5.!notice /var/log/swift/storage4.log local5.notice /var/log/swift/storage4.error local5.* ~ local6.*;local6.!notice /var/log/swift/expirer.log local6.notice /var/log/swift/expirer.error local6.* ~Edit /etc/rsyslog.conf and make the following change (usually in the “GLOBAL DIRECTIVES” section):
$PrivDropToGroup admIf using hourly logs (see above) perform:
sudo mkdir -p /var/log/swift/hourlyOtherwise perform:
sudo mkdir -p /var/log/swiftSetup the logging directory and start syslog:
On Ubuntu:
sudo chown -R syslog.adm /var/log/swift sudo chmod -R g+w /var/log/swift sudo service rsyslog restartOn Fedora:
sudo chown -R root:adm /var/log/swift sudo chmod -R g+w /var/log/swift sudo systemctl restart rsyslog.service
After performing the following steps, be sure to verify that Swift has access to resulting configuration files (sample configuration files are provided with all defaults in line-by-line comments).
Optionally remove an existing swift directory:
sudo rm -rf /etc/swiftPopulate the /etc/swift directory itself:
cd $HOME/swift/doc; sudo cp -r saio/swift /etc/swift; cd - sudo chown -R ${USER}:${USER} /etc/swiftUpdate <your-user-name> references in the Swift config files:
find /etc/swift/ -name \*.conf | xargs sudo sed -i "s/<your-user-name>/${USER}/"
The contents of the configuration files provided by executing the above commands are as follows:

$HOME/swift/.unittestsNote that the unit tests do not require any swift daemons running.
Start the “main” Swift daemon processes (proxy, account, container, and object):
startmain(The “Unable to increase file descriptor limit. Running as non-root?” warnings are expected and ok.)
The startmain script looks like the following:
#!/bin/bash swift-init main startGet an X-Storage-Url and X-Auth-Token:
curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing' http://127.0.0.1:8080/auth/v1.0Check that you can GET account:
curl -v -H 'X-Auth-Token: <token-from-x-auth-token-above>' <url-from-x-storage-url-above>Check that swift command provided by the python-swiftclient package works:
swift -A http://127.0.0.1:8080/auth/v1.0 -U test:tester -K testing statVerify the functional tests run:
$HOME/swift/.functests(Note: functional tests will first delete everything in the configured accounts.)
Verify the probe tests run:
$HOME/swift/.probetests(Note: probe tests will reset your environment as they call resetswift for each test.)
If all doesn’t go as planned, and tests fail, or you can’t auth, or something doesn’t work, here are some good starting places to look for issues:
