当确定集群的成员个数及其信息，可以使用静态模式(Static)部署集群，具体步骤如下：
一、机器信息
| hostname | ip | 系统版本 |
|---|---|---|
| infra0 | 172.17.0.2 | CentOS Linux release 7.4.1708 (Core) |
| infra1 | 172.17.0.3 | CentOS Linux release 7.4.1708 (Core) |
| infra2 | 172.17.0.4 | CentOS Linux release 7.4.1708 (Core) |
二、下载etcd二进制包
wget https://github.com/coreos/etcd/releases/download/v3.2.10/etcd-v3.2.10-linux-amd64.tar.gz tar -xf etcd-v3.2.10-linux-amd64.tar.gz sudo mv etcd-v3.2.10-linux-amd64/etcd* /usr/local/bin/ etcd --version -------------------------------- etcd Version: 3.2.10 Git SHA: 694728c Go Version: go1.8.5 Go OS/Arch: linux/amd64 -------------------------------- etcdctl --version ------------------------------ etcdctl version: 3.2.10 API version: 2- ------------------------------
三、启动节点
1.infra0节点执行命令
NODE_INFRA0_IP=172.17.0.2
NODE_INFRA1_IP=172.17.0.3
NODE_INFRA2_IP=172.17.0.4
mkdir -p /data/etcd/data_dir
nohup etcd --name infra0 --data-dir /data/etcd/data_dir \
--initial-advertise-peer-urls http://${NODE_INFRA0_IP}:2380 \
--listen-peer-urls http://${NODE_INFRA0_IP}:2380 \
--listen-client-urls http://${NODE_INFRA0_IP}:2379,http://127.0.0.1:2379 \
--advertise-client-urls http://${NODE_INFRA0_IP}:2379 \
--initial-cluster-token etcd-cluster-1 \
--initial-cluster infra0=http://${NODE_INFRA0_IP}:2380,infra1=http://${NODE_INFRA1_IP}:2380,infra2=http://${NODE_INFRA2_IP}:2380 \
--initial-cluster-state new >> /data/etcd/etcd.log 2>&1 &
2.infra1节点执行命令
NODE_INFRA0_IP=172.17.0.2
NODE_INFRA1_IP=172.17.0.3
NODE_INFRA2_IP=172.17.0.4
mkdir -p /data/etcd/data_dir
nohup etcd --name infra1 --data-dir /data/etcd/data_dir \
--initial-advertise-peer-urls http://${NODE_INFRA1_IP}:2380 \
--listen-peer-urls http://${NODE_INFRA1_IP}:2380 \
--listen-client-urls http://${NODE_INFRA1_IP}:2379,http://127.0.0.1:2379 \
--advertise-client-urls http://${NODE_INFRA1_IP}:2379 \
--initial-cluster-token etcd-cluster-1 \
--initial-cluster infra0=http://${NODE_INFRA0_IP}:2380,infra1=http://${NODE_INFRA1_IP}:2380,infra2=http://${NODE_INFRA2_IP}:2380 \
--initial-cluster-state new >> /data/etcd/etcd.log 2>&1 &
3.infra2节点执行命令
NODE_INFRA0_IP=172.17.0.2
NODE_INFRA1_IP=172.17.0.3
NODE_INFRA2_IP=172.17.0.4
mkdir -p /data/etcd/data_dir
nohup etcd --name infra2 --data-dir /data/etcd/data_dir \
--initial-advertise-peer-urls http://${NODE_INFRA2_IP}:2380 \
--listen-peer-urls http://${NODE_INFRA2_IP}:2380 \
--listen-client-urls http://${NODE_INFRA2_IP}:2379,http://127.0.0.1:2379 \
--advertise-client-urls http://${NODE_INFRA2_IP}:2379 \
--initial-cluster-token etcd-cluster-1 \
--initial-cluster infra0=http://${NODE_INFRA0_IP}:2380,infra1=http://${NODE_INFRA1_IP}:2380,infra2=http://${NODE_INFRA2_IP}:2380 \
--initial-cluster-state new >> /data/etcd/etcd.log 2>&1 &
四、检查集群状态
etcdctl cluster-health #在任意节点执行 member 9198227ac1a2c055 is healthy: got healthy result from http://172.17.0.3:2379 member 983274ac8c0149ec is healthy: got healthy result from http://172.17.0.2:2379 member ab3fbede047aa1ac is healthy: got healthy result from http://172.17.0.4:2379 cluster is healthy
