修改 etcd.service
[root@localhost etcd]# cat /usr/lib/systemd/system/etcd.service
[Service]
Type=notify
WorkingDirectory=/var/lib/etcd/
EnvironmentFile=-/etc/etcd/etcd.conf
User=etcd
# set GOMAXPROCS to number of processors
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=\"${ETCD_LISTEN_CLIENT_URLS}\" --initial-advertise-peer-urls=\"${ETCD_INITIAL_ADVERTISE_PEER_URLS}\" --advertise-client-urls=\"${ETCD_ADVERTISE_CLIENT_URLS}\" --initial-cluster=\"${ETCD_INITIAL_CLUSTER}\" --initial-cluster-token=\"${ETCD_INITIAL_CLUSTER_TOKEN}\" --initial-cluster-state=\"${ETCD_INITIAL_CLUSTER_STATE}\""
Restart=on-failure
LimitNOFILE=65536
以上操作在 node1、node2、node3 节点上都需要操作,需要修改对应的ip
依次启动 node1、node2、node3 节点的 etcd
systemctl start etcd.service systemctl status etcd.service systemctl enable etcd.service
验证 etcd
etcdctl cluster-health
etcdctl member list
各个节点配置crontab 定时同步时间，否则可能会出现node1 etcd[1657]: the clock difference against peer f63afbe816fb463d is too hig问题
yum install ntp crontab -e 0 1 * * * /usr/sbin/ntpdate ntp.sjtu.edu.cn >> /var/log/ntpdate.log 2>&1 &
