K8S集群中etcd启动的问题。

我的master节点是192.168.237.144，两个node节点分别是192.168.237.143和192.168.237.146
创建 etcd配置文件

cat > /opt/etcd/cfg/etcd.conf << EOF

master节点的ETCD_NAME="etcd-1"，node节点分别为2和3，ip也换了
systemd管理 etcd

cat > /usr/lib/systemd/system/etcd.service << EOF

master节点和node节点都有上述文件。
启动并设置开机启动（3个节点都有）

systemctl daemon-reload 
systemctl start etcd 
systemctl enable etcd

在执行第二句systemctl start etcd 的时候报了如下错：

[root@k8snode2 ~]# systemctl daemon-reload 
[root@k8snode2 ~]# systemctl start etcd 
Job for etcd.service failed because the control process exited with error code. See "systemctl status etcd.service" and "journalctl -xe" for details.
[root@k8snode2 ~]# 

有人知道是怎么回事吗？

你去查查你部署的etcd部署目录下的日志，有什么报错提示

单独执行看下报什么错误，再根据报错信息排查问题
source /opt/etcd/cfg/etcd.conf

/opt/etcd/bin/etcd
--cert-file=/opt/etcd/ssl/server.pem
--key-file=/opt/etcd/ssl/server-key.pem
--peer-cert-file=/opt/etcd/ssl/server.pem
--peer-key-file=/opt/etcd/ssl/server-key.pem
--trusted-ca-file=/opt/etcd/ssl/ca.pem
--peer-trusted-ca-file=/opt/etcd/ssl/ca.pem
--logger=zap
