二、Kubernetes_V1.10集群部署-master-etcd

 

1.ETCD集群服务器：

（1）172.18.6.39

（2）172.18.6.40

（3）172.18.6.41

1.安装etcd

# yum -y install etcd

2.发布证书

cp -a /etc/kubernetes/ssl /etc/etcd/

3.添加配置文件

（1）节点[172.18.6.39]

3.启动服务

# systemctl start etcd
# systemctl enable etcd

4.查看etcd集群状态

# etcdctl   --ca-file=/etc/etcd/ssl/ca.pem   --cert-file=/etc/etcd/ssl/server.pem   --key-file=/etc/etcd/ssl/server-key.pem   --endpoints=https://172.18.6.39:2379,https://172.18.6.40:2379,https://172.18.6.41:2379   cluster-health
member 166097e900c8cd52 is healthy: got healthy result from https://172.18.6.41:2379
member afe1cb78e6e4ef23 is healthy: got healthy result from https://172.18.6.40:2379
member e61819fce46c79f2 is healthy: got healthy result from https://172.18.6.39:2379
cluster is healthy
