|
This section shows how to use Swift Storage from Clients. This example is based on the environment like follows.
------------+--------------------------+------------
| |
eth0|10.0.0.30 eth0|10.0.0.50
+-----------+-----------+ +-----------+-----------+
| [ dlp.srv.world ] | | [ network.srv.world ] |
| (Control Node) | | (Proxy Node) |
| | | |
| MariaDB RabbitMQ | | Swift Proxy |
| Memcached Nginx | | Nginx |
| Keystone httpd | | |
+-----------------------+ +-----------------------+
------------+--------------------------+--------------------------+-----------
eth0|10.0.0.71 eth0|10.0.0.72 eth0|10.0.0.73
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [snode01.srv.world] | | [snode02.srv.world] | | [snode03.srv.world] |
| (Storage Node#1) | | (Storage Node#2) | | (Storage Node#3) |
| | | | | |
| Swift-Account | | Swift-Account | | Swift-Account |
| Swift-Container | | Swift-Container | | Swift-Container |
| Swift-Object | | Swift-Object | | Swift-Object |

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

| [2] | Work on a Client Host from here and later. Install Keystoneclient, Swiftclient on a Client Host first. |
|
[root@client ~]# dnf --enablerepo=centos-openstack-epoxy,epel,crb -y install python3-openstackclient python3-keystoneclient python3-swiftclient
|
| [3] | Login as any user and load environment variables. ( it's just the value for a user added in [1] ) |
|
[cent@client ~]$
vi ~/keystonerc_swift
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default export OS_PROJECT_NAME=swiftservice export OS_USERNAME=swiftuser01 export OS_PASSWORD=userpassword export OS_AUTH_URL=https://dlp.srv.world:5000 export OS_IDENTITY_API_VERSION=3 export PS1='[\u@\h \W(swift)]\$ '
[cent@client ~]$
chmod 600 ~/keystonerc_swift [cent@client ~]$ source ~/keystonerc_swift [cent@client ~(swift)]$ echo "source ~/keystonerc_swift " >> ~/.bash_profile
