Question

我正在尝试使用命令“etcdctl member add core2 http://172.31.12.183:2380”向我的CoreOS群集添加一个额外的etcd节点，但是这个命令使我的新节点没有启动，因此我的群集不健康。在运行etcdctl member add命令后，如何解决此问题或启动新节点？以下是我运行此命令时的输出以及之后的集群状态：

core@ip-172-31-12-183 ~ $ etcdctl member add core2 http://172.31.12.183:2380
Added member named core2 with ID 4d14f3cb088a2f54 to cluster

ETCD_NAME="core2"
ETCD_INITIAL_CLUSTER="core2=http://172.31.12.183:2380,ec2c8c9d2cf141cf9657e98b260895a5=http://172.31.12.182:2380"
ETCD_INITIAL_CLUSTER_STATE="existing"
core@ip-172-31-12-183 ~ $ etcdctl member list

core@ip-172-31-12-183 ~ $ etcdctl cluster-health
member 4d14f3cb088a2f54 is unreachable: no available published client urls
member aedf0a441a723d8a is unhealthy: got unhealthy result from http://172.31.12.182:2379
cluster is unhealthy

Answer 1

简单地说，您添加成员的步骤是错误的。
与官方docs一样，我假设add a new member to a 1-node cluster的步骤是您的方案：

启动第一个节点
运行etcdctl member add
启动具有群集相关选项的第二个节点

所以根据你的情况：

core2

，运行=＆gt;

etcdctl member add core2 http://172.31.12.183:2380

然后，使用与群集相关的选项启动core2 =＆gt;

./etcd --name core2 --initial-advertise-peer-urls http://172.31.12.183:2380 \
  --listen-peer-urls http://172.31.12.183:2380 \
  --listen-client-urls http://172.31.12.183:2379 \
  --advertise-client-urls http://172.31.12.183:2379 \
  --initial-cluster core2=http://172.31.12.183:2380,ec2c8c9d2cf141cf9657e98b260895a5=http://172.31.12.182:2380 \
  --initial-cluster-state existing

使用“etcdctl member add”时，CoreOS成员节点将无法启动
