|
| [1] | Add a user for using Swift on Keystone Control Node. By the way, if you'd like to use Swift Quickly, it's unnecessarry to add a new user, it's posibble to use with existing admin or swift user on Keystone. |

|
| [2] | Work on a Client from here and later. Install Keystoneclient, Swiftclient on a Client first. |
|
[root@client ~]# yum --enablerepo=centos-openstack-liberty,epel -y install python-keystoneclient python-swiftclient
|
| [3] | Load environment variables first. ( it's just the value for a user added in [1] ) |
|
[root@client ~]#
vi ~/keystonerc_swift
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default export OS_PROJECT_NAME=swiftservice export OS_TENANT_NAME=swiftservice export OS_USERNAME=user01 export OS_PASSWORD=userpassword export OS_AUTH_URL=http://10.0.0.30:35357/v3 export OS_IDENTITY_API_VERSION=3 export OS_AUTH_VERSION=3 export PS1='[\u@\h \W(swift)]\$ '
[root@client ~]#
chmod 600 ~/keystonerc_swift [root@client ~]# source ~/keystonerc_swift [root@client ~(swift)]# echo "source ~/keystonerc_swift " >> ~/.bash_profile
# display status (it's not need to care the Warning below) [root@client ~(swift)]# swift stat

| [4] | Create a Container for saving files. By the way, the same Warings are displayed every time on swift command, if you feel troublesome, add " 2>/dev/null" to the tail of every command to redirect. |

[root@client ~(swift)]# swift post test_container [root@client ~(swift)]# swift list test_container # just created |
| [5] | Upload a file on local to the Container. |
|
# upload test.txt [root@client ~(swift)]# swift upload test_container test.txt test.txt [root@client ~(swift)]# swift list test_container test.txt # just uploaded |
| [6] | Download a file from Swift Storage to local. |
|
[root@client ~(swift)]# swift download test_container test.txt test.txt [auth 0.243s, headers 0.497s, total 0.497s, 0.000 MB/s] [root@client ~(swift)]# total 12 -rw-------. 1 root root 985 Jan 8 2015 anaconda-ks.cfg -rw------- 1 root root 335 Nov 18 23:03 keystonerc_swift -rw-r--r-- 1 root root 10 Nov 18 23:05 test.txt |
| [7] | Delete a file on Swift Storage. |
|
[root@client ~(swift)]# swift delete test_container test.txt test.txt [root@client ~(swift)]# swift list test_container test2.txt # test.txt is just deleted |
| [8] | Delete a Container on Swift Storage. |
