整体架构思路
etcd 启动
etcd --name=node1 \
--listen-client-urls http://127.0.0.1:2379 \
--advertise-client-urls http://127.0.0.1:2379 \
--listen-peer-urls http://127.0.0.1:2380 \
--initial-advertise-peer-urls http://127.0.0.1:2380 \
--initial-cluster node1=http://127.0.0.1:2380,node2=http://127.0.0.1:2480,node3=http://127.0.0.1:2580 \
--initial-cluster-state new --initial-cluster-token token-1
etcd --name=node2 \
--listen-client-urls http://127.0.0.1:2479 \
--advertise-client-urls http://127.0.0.1:2479 \
--listen-peer-urls http://127.0.0.1:2480 \
--initial-advertise-peer-urls http://127.0.0.1:2480 \
--initial-cluster node1=http://127.0.0.1:2380,node2=http://127.0.0.1:2480,node3=http://127.0.0.1:2580 \
--initial-cluster-state new --initial-cluster-token token-1
etcd --name=node3 \
--listen-client-urls http://127.0.0.1:2579 \
--advertise-client-urls http://127.0.0.1:2579 \
--listen-peer-urls http://127.0.0.1:2580 \
--initial-advertise-peer-urls http://127.0.0.1:2580 \
--initial-cluster node1=http://127.0.0.1:2380,node2=http://127.0.0.1:2480,node3=http://127.0.0.1:2580 \
--initial-cluster-state new --initial-cluster-token token-1
添加一个节点
etcdctl --endpoints=127.0.0.1:2379,127.0.0.1:2479,127.0.0.1:2579 member add node4 --peer-urls=http://127.0.0.1:2180
etcd --name node4 --listen-client-urls http://127.0.0.1:2179 \
--advertise-client-urls http://127.0.0.1:2179 \
--listen-peer-urls http://127.0.0.1:2180 \
--initial-advertise-peer-urls http://127.0.0.1:2180 \
--initial-cluster-state existing \
--initial-cluster node1=http://127.0.0.1:2380,node2=http://127.0.0.1:2480,node3=http://127.0.0.1:2580,node4=http://127.0.0.1:2180 \
--initial-cluster-token token-1
