1.将有故障的etcd节点remove出集群:
ETCDCTL_API=3 /opt/etcd/bin/etcdctl –cacert=/opt/etcd/ssl/ca.pem –cert=/opt/etcd/ssl/server.pem –key=/opt/etcd/ssl/server-key.pem –endpoints=”https://192.168.233.91:2379,https://192.168.233.93:2379,https://192.168.233.94:2379″ –write-out=table member list

/opt/etcd/bin/etcdctl –cacert=/opt/etcd/ssl/ca.pem –cert=/opt/etcd/ssl/server.pem –key=/opt/etcd/ssl/server-key.pem –endpoints=”https://192.168.233.91:2379,https://192.168.233.93:2379,https://192.168.233.94:2379″ member remove 故障节点的id
2、来到故障节点
rm -rf /var/lib/etcd/default.etcd/member/
修改etcd配置文件,将下面new修改为:
vim /opt/etcd/cfg/etcd
修改前:
ETCD_INITIAL_CLUSTER_STATE=”new”
修改后:
ETCD_INITIAL_CLUSTER_STATE=”existing”
3、重新加入etcd集群：
/opt/etcd/bin/etcdctl –cacert=/opt/etcd/ssl/ca.pem –cert=/opt/etcd/ssl/server.pem –key=/opt/etcd/ssl/server-key.pem –endpoints=”https://192.168.233.91:2379,https://192.168.233.93:2379,https://192.168.233.94:2379″ member add etcd-2 –peer-urls=https://192.168.233.94:2380
4、重启etcd故障节点
