一、查看集群节点
[root@linux-node1 ~]# etcdctl --endpoints=https://192.168.56.11:2379 --ca-file=/opt/kubernetes/ssl/ca.pem --cert-file=/opt/kubernetes/ssl/etcd.pem --key-file=/opt/kubernetes/ssl/etcd-key.pem member list
435fb0a8da627a4c: name=etcd-node2 peerURLs=https://192.168.56.12:2380 clientURLs=https://192.168.56.12:2379 isLeader=false
6566e06d7343e1bb: name=etcd-node1 peerURLs=https://192.168.56.11:2380 clientURLs=https://192.168.56.11:2379 isLeader=true
65421783297483vb: name=etcd-node3 peerURLs=https://192.168.56.13:2380 clientURLs=https://192.168.56.13:2379 isLeader=false
二、删除节点
etcdctl member remove 65421783297483vb
三、再次查看集群，此节点已删除
[root@linux-node1 ~]# etcdctl --endpoints=https://192.168.56.11:2379 --ca-file=/opt/kubernetes/ssl/ca.pem --cert-file=/opt/kubernetes/ssl/etcd.pem --key-file=/opt/kubernetes/ssl/etcd-key.pem member list
435fb0a8da627a4c: name=etcd-node2 peerURLs=https://192.168.56.12:2380 clientURLs=https://192.168.56.12:2379 isLeader=false
6566e06d7343e1bb: name=etcd-node1 peerURLs=https://192.168.56.11:2380 clientURLs=https://192.168.56.11:2379 isLeader=true
修改配置文件etcd.conf，修改参数ETCD_INITIAL_CLUSTER并移除节点信息，重启etcd服务
