2. 更新配置文件

tee /etc/etcd/etcd.conf <<-'EOF'
ETCD_NAME=etcd03
ETCD_DATA_DIR="/var/lib/etcd/etcd03"
ETCD_LISTEN_PEER_URLS="http://192.168.2.46:2380"

ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.2.46:2380"
ETCD_ADVERTISE_CLIENT_URLS="http://192.168.2.46:2379"
ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster1"
ETCD_INITIAL_CLUSTER="etcd01=http://192.168.2.44:2380,etcd02=http://192.168.2.45:2380,etcd03=http://192.168.2.46:2380"

3. 更新启动

systemctl daemon-reload
systemctl start etcd
systemctl enable etcd

4. 校验状态

etcdctl member list 
etcdctl cluster-health

本文内容总结：1. 使用yum安装etcd，2. 更新配置文件，3. 更新启动，4. 校验状态，
