Hello,Stackers First question: I built a swift cluser,two proxy server , one nginx server ---load balance for two swift proxy server,and two storage server 1.when I stop swift proxy service on one proxy server The command " swift -V 2 -A http://172.18.56.195:5000/v2.0 -U service:glance -K pass list" can not list all containers. like this,before I stop the proxy service ,there are five containers. root at proxy:~# swift -V 2 -A http://172.18.56.195:5000/v2.0 -U service:glance -K pass list 1 2 myfile test test3 once I stop one proxy server ,there are only 3 . root at proxy:~# swift -V 2 -A http://172.18.56.195:5000/v2.0 -U service:glance -K pass list 1 2 test the nginx.conf like this worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; client_max_body_size 10024M; upstream swift { server 172.18.56.199:8080; server 172.18.56.235:8080; } server { listen 8080; server_name authserver; location / { proxy_pass http://authserver/; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } } Question 2: Because of the nginx problem ,so I change to use pound ,but when I execute the command swift -V 2 -A http://172.18.56.195:5000/v2.0 -U service:glance -K pass stat and swift -V 2 -A http://172.18.56.195:5000/v2.0 -U service:glance -K pass list It runs successfully but can not execute post or upload the error like this root at proxy:~# swift -V 2 -A http://172.18.56.195:5000/v2.0 -U service:glance -K pass post 3 Container PUT failed: http://172.18.56.194:80/v1/AUTH_aadcbf03cf904eb68742478c9ae38eb4/3 501 Not Implemented This method may not be used. the pound.conf like this User "root" Group "root" ListenHTTP Address 172.18.56.194 Port 80 End Service #HeadRequire "(Host: your_host.com|Host: www.your_host.com)" BackEnd Address 172.18.56.235 Port 8080 End BackEnd Address 172.18.56.199 Port 8080 End End Cheers Wenna -------------- next part -------------- An HTML attachment was scrubbed...
