| [2] | This is Client's settings. Install Keystoneclient, Swiftclient first. |
|
# install from EPEL OpenStack, EPEL [root@client ~]# yum --enablerepo=openstack-havana,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_USERNAME=user01
export OS_PASSWORD=userpassword export OS_TENANT_NAME=swiftservice export OS_AUTH_URL=http://10.0.0.30:35357/v2.0/ 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
