| [2] | Work on a Client from here and later. Install Keystoneclient, Swiftclient on a Client first. |
|
[root@client ~]# yum --enablerepo=centos-openstack-newton,epel -y install python-openstackclient 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_USER_DOMAIN_NAME=default export OS_PROJECT_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 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
