I verified step 1: use etcdctl add user apisix and grant all privilege on /apisix/* command like ```shell etcdctl --endpoints=http://127.0.0.1:2379 user add apisix etcdctl --endpoints=http://127.0.0.1:2379 role add apisix etcdctl --endpoints=http://127.0.0.1:2379 user grant-role apisix apisix etcdctl --endpoints=http://127.0.0.1:2379 role grant-permission apisix --prefix=true readwrite /apisix/ etcdctl --endpoints=http://127.0.0.1:2379 auth enable ``` step 2: edit apisix/conf/config.yaml, add the user to apisix the config.yaml like ```yaml etcd: host: - "http://127.0.0.1:2379"; prefix: "/apisix" user: apisix password: abc123 ``` step 3: curl metrics command like ```shell http://127.0.0.1:9080/apisix/prometheus/metrics ``` step 4: error.log I get the error.log like ```nginx 2021/04/28 14:00:16 [error] 57379#1168662: *12753 [lua] http.lua:913: request_uri(): unread data in buffer, client: ::1, server: , request: "GET /apisix/prometheus/metrics HTTP/1.1", host: "localhost:9080" 2021/04/28 14:00:16 [error] 57379#1168662: *12753 lua entry thread aborted: runtime error: /usr/local/Cellar/apisix/apisix/core/etcd.lua:92: attempt to index field 'header' (a nil value) stack traceback: coroutine 0: /usr/local/Cellar/apisix/apisix/core/etcd.lua: in function 'get_format' /usr/local/Cellar/apisix/apisix/core/config_etcd.lua:75: in function 'getkey' ...cal/Cellar/apisix/apisix/plugins/prometheus/exporter.lua:310: in function 'handler' /usr/local/Cellar/apisix/apisix/api_router.lua:130: in function 'handler' ...al/Cellar/apisix//deps/share/lua/5.1/resty/radixtree.lua:720: in function 'dispatch' /usr/local/Cellar/apisix/apisix/api_router.lua:165: in function 'match' /usr/local/Cellar/apisix/apisix/init.lua:292: in function 'http_access_phase' access_by_lua(nginx.conf:209):2: in main chunk, client: ::1, server: , request: "GET /apisix/prometheus/metrics HTTP/1.1", host: "localhost:9080" ``` by the way, when I switched to apisix 2.5, I got a similar error starting apisix, which seems to be a problem with apisix and etcd interaction. -- This is an automated message from the Apache Git Service.
