K8s二进制安装之ETCD错误

etcd v3.4.9

使用member list查询etcd状态或者使用endpoint health查询群集状态时

#etcdctl member list

出现如下信息，切记不是报错信息，只是通过客户端访问的时候需要带上证书访问

{"level":"warn","ts":"2021-02-23T02:42:32.148-0500","caller":"clientv3/retry_interceptor.go:62","msg":"retrying of unary invoker failed","target":"endpoint://client-633d3464-2a3d-432c-a269-01eb26d31ba0/127.0.0.1:2379","attempt":0,"error":"rpc error: code = DeadlineExceeded desc = latest balancer error: all SubConns are in TransientFailure, latest connection error: connection error: desc = \"transport: Error while dialing dial tcp 127.0.0.1:2379: connect: connection refused\""}

Error: context deadline exceeded

#etcdctl endpoint health

正确的访问方法：

#etcdctl --cacert=/opt/etcd/ssl/ca.pem --cert=/opt/etcd/ssl/server.pem --key=/opt/etcd/ssl/server-key.pem \
