ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-00"
ETCD_ADVERTISE_CLIENT_URLS="http://192.168.1.103:2379"

 

3. 配置启动命令

cat /usr/lib/systemd/system/etcd.service

[Unit]
 
Description=Etcd Server
 
After=network.target
 
After=network-online.target
 
Wants=network-online.target
 
[Service]
 
Type=notify
 
WorkingDirectory=/var/lib/etcd/
 
EnvironmentFile=-/etc/etcd/etcd.conf
 
User=etcd
 
ExecStart=/bin/bash -c "GOMAXPROCS=$(nproc) /usr/bin/etcd --name=\"${ETCD_NAME}\" \
--data-dir=\"${ETCD_DATA_DIR}\" \
--listen-peer-urls=\"${ETCD_LISTEN_PEER_URLS}\" \
--listen-client-urls=\"${ETCD_LISTEN_CLIENT_URLS}\" \
--advertise-client-urls=\"${ETCD_ADVERTISE_CLIENT_URLS}\" \
--initial-cluster-token=\"${ETCD_INITIAL_CLUSTER_TOKEN}\" \
--initial-cluster=\"${ETCD_INITIAL_CLUSTER}\" \
--initial-cluster-state=\"${ETCD_INITIAL_CLUSTER_STATE}\""
 
Restart=on-failure
 
LimitNOFILE=65536
 
[Install]
 
WantedBy=multi-user.target
