靜態啓動
需要三臺物理機或虛擬機
$ etcd --name infra0 --initial-advertise-peer-urls http://10.0.1.10:2380 \ --listen-peer-urls http://10.0.1.10:2380 \ --listen-client-urls http://10.0.1.10:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://10.0.1.10:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra0=http://10.0.1.10:2380,infra1=http://10.0.1.11:2380,infra2=http://10.0.1.12:2380 \ --initial-cluster-state new $ etcd --name infra1 --initial-advertise-peer-urls http://10.0.1.11:2380 \ --listen-peer-urls http://10.0.1.11:2380 \ --listen-client-urls http://10.0.1.11:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://10.0.1.11:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra0=http://10.0.1.10:2380,infra1=http://10.0.1.11:2380,infra2=http://10.0.1.12:2380 \ --initial-cluster-state new $ etcd --name infra2 --initial-advertise-peer-urls http://10.0.1.12:2380 \ --listen-peer-urls http://10.0.1.12:2380 \ --listen-client-urls http://10.0.1.12:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://10.0.1.12:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra0=http://10.0.1.10:2380,infra1=http://10.0.1.11:2380,infra2=http://10.0.1.12:2380 \ --initial-cluster-state new
2. etcd服務發現
在任意設備上執行，如果不加size，則默認爲3 $ curl -w "\n" https://discovery.etcd.io/new?size=3
$ etcd --name infra0 --initial-advertise-peer-urls http://10.0.1.10:2380 \ --listen-peer-urls http://10.0.1.10:2380 \ --listen-client-urls http://10.0.1.10:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://10.0.1.10:2379 \ --discovery https://discovery.etcd.io/3e86b59982e49066c5d813af1c2e2579cbf573de $ etcd --name infra1 --initial-advertise-peer-urls http://10.0.1.11:2380 \ --listen-peer-urls http://10.0.1.11:2380 \ --listen-client-urls http://10.0.1.11:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://10.0.1.11:2379 \ --discovery https://discovery.etcd.io/3e86b59982e49066c5d813af1c2e2579cbf573de $ etcd --name infra2 --initial-advertise-peer-urls http://10.0.1.12:2380 \ --listen-peer-urls http://10.0.1.12:2380 \ --listen-client-urls http://10.0.1.12:2379,http://127.0.0.1:2379 \ --advertise-client-urls http://10.0.1.12:2379 \ --discovery https://discovery.etcd.io/3e86b59982e49066c5d813af1c2e2579cbf573de
3. dns服務發現
該方式目前還沒有嘗試，所以不予以貼出，有興趣可以去官網查看！
注意：其中的ip地址需要根據自己的實際情況進行修改，127.0.0.1:2379不需要修改，否則會報錯：bind: address already in use
