OpenStack Dalmatian : Octavia का उपयोग कैसे करें2024/10/24 |
OpenStack लोड बैलेंसिंग को एक सेवा (Octavia) के रूप में स्थापित करें।
यह उदाहरण निम्न प्रकार से पर्यावरण पर आधारित है।

[1] | Octavia क्लाइंट टूल इंस्टॉल करें। |
root@dlp ~(keystone)# apt -y install python3-octaviaclient
|
[2] | किसी भी Openstack उपयोगकर्ता के रूप में लॉगिन करें और लोड बैलेंसर इंस्टेंस बनाएं। किसी भी नोड पर काम करना ठीक है. (नीचे उदाहरण नियंत्रण नोड पर है) |
