etcd单机集群
etcd在单机部署集群,可以先弄清楚配置文件参数的意思。起3个集成监听不同的端口号
1. 启动
在/etc/soft/etcd/node1文件夹中,创建脚本start1.sh
etcd --name infra1 --initial-advertise-peer-urls http://127.0.0.1:2381 \ --listen-peer-urls http://127.0.0.1:2381 \ --listen-client-urls http://127.0.0.1:2379 \ --advertise-client-urls http://127.0.0.1:2379 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra1=http://127.0.0.1:2381,infra2=http://127.0.0.1:2382,infra3=http://127.0.0.1:2383 \ --initial-cluster-state new
在/etc/soft/etcd/node2文件夹中,创建脚本start2.sh
etcd --name infra2 --initial-advertise-peer-urls http://127.0.0.1:2382 \ --listen-peer-urls http://127.0.0.1:2382 \ --listen-client-urls http://127.0.0.1:2378 \ --advertise-client-urls http://127.0.0.1:2378 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra1=http://127.0.0.1:2381,infra2=http://127.0.0.1:2382,infra3=http://127.0.0.1:2383 \ --initial-cluster-state new
在/etc/soft/etcd/node3文件夹中,创建脚本start3.sh
etcd --name infra3 --initial-advertise-peer-urls http://127.0.0.1:2383 \ --listen-peer-urls http://127.0.0.1:2383 \ --listen-client-urls http://127.0.0.1:2377 \ --advertise-client-urls http://127.0.0.1:2377 \ --initial-cluster-token etcd-cluster-1 \ --initial-cluster infra1=http://127.0.0.1:2381,infra2=http://127.0.0.1:2382,infra3=http://127.0.0.1:2383 \ --initial-cluster-state new
分别运行三个脚本
2. 检查集群是否启动成功
etcdctl --endpoint "http://127.0.0.1:2379" member list
19ac17627e3e396f: name=infra2 peerURLs=http://127.0.0.1:2382 clientURLs=http://127.0.0.1:2378 isLeader=false 8f65a5fdd9ee42ad: name=infra3 peerURLs=http://127.0.0.1:2383 clientURLs=http://127.0.0.1:2377 isLeader=true e7b968b9fb1bc003: name=infra1 peerURLs=http://127.0.0.1:2381 clientURLs=http://127.0.0.1:2379 isLeader=false
etcdctl cluster-health
member 19ac17627e3e396f is healthy: got healthy result from http://127.0.0.1:2378 member 8f65a5fdd9ee42ad is healthy: got healthy result from http://127.0.0.1:2377 member e7b968b9fb1bc003 is healthy: got healthy result from http://127.0.0.1:2379
3个节点启动完成
