测试三
root@node-1:/opt/kolla-ansible/ansible/roles/skyline/templates# curl -X GET -H "X-Auth-Token: $Token" -H "Cookie: $Cookie" -H "Content-Type: application/json" http://192.168.27.253:9999/api/openstack/regionone/octaviav2
"v2"
通过测试可知调用skyline-console地址http://192.168.27.253:9999/api/openstack/regionone/octavia/访问octavia-api时，skyline的nginx会将http://192.168.27.253:9999/api/openstack/regionone/octavia重定向成http://192.168.27.253:9876//，导致资源访问失败。
修复方案：
将https://opendev.org/openstack/kolla-ansible/src/branch/master/ansible/roles/skyline/templates/nginx.conf.j2第184行
location {{ skyline_nginx_prefix }}/{{ openstack_region_name | lower }}/octavia {
改为：
location {{ skyline_nginx_prefix }}/{{ openstack_region_name | lower }}/octavia/ {
