yum安装etcd
yum install etcd yum list installed |grep -i etcd
node1 etcd 配置
cp /etc/etcd/etcd.conf /etc/etcd/etcd.conf.bak cd /etc/etcd/ [[email protected] etcd]# egrep ^[A-Z] ./etcd.conf ETCD_DATA_DIR="/var/lib/etcd/node1.etcd" ETCD_LISTEN_PEER_URLS="http://192.168.216.130:2380" ETCD_LISTEN_CLIENT_URLS="http://192.168.216.130:2379,http://127.0.0.1:2379" ETCD_NAME="node1" ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.216.130:2380" ETCD_ADVERTISE_CLIENT_URLS="http://192.168.216.130:2379" ETCD_INITIAL_CLUSTER="node1=http://192.168.216.130:2380,node2=http://192.168.216.132:2380,node3=http://192.168.216.134:2380" ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster" ETCD_INITIAL_CLUSTER_STATE="new"
node2 etcd 配置
cp /etc/etcd/etcd.conf /etc/etcd/etcd.conf.bak cd /etc/etcd/ [[email protected] etcd]# egrep ^[A-Z] ./etcd.conf ETCD_DATA_DIR="/var/lib/etcd/node2.etcd" ETCD_LISTEN_PEER_URLS="http://192.168.216.132:2380" ETCD_LISTEN_CLIENT_URLS="http://192.168.216.132:2379,http://127.0.0.1:2379" ETCD_NAME="node2" ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.216.132:2380" ETCD_ADVERTISE_CLIENT_URLS="http://192.168.216.132:2379" ETCD_INITIAL_CLUSTER="node1=http://192.168.216.130:2380,node2=http://192.168.216.132:2380,node3=http://192.168.216.134:2380" ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster" ETCD_INITIAL_CLUSTER_STATE="new"
node3 etcd 配置
cp /etc/etcd/etcd.conf /etc/etcd/etcd.conf.bak cd /etc/etcd/ [[email protected] etcd]# egrep ^[A-Z] ./etcd.conf ETCD_DATA_DIR="/var/lib/etcd/node3.etcd" ETCD_LISTEN_PEER_URLS="http://192.168.216.134:2380" ETCD_LISTEN_CLIENT_URLS="http://192.168.216.134:2379,http://127.0.0.1:2379" ETCD_NAME="node3" ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.216.134:2380" ETCD_ADVERTISE_CLIENT_URLS="http://192.168.216.134:2379" ETCD_INITIAL_CLUSTER="node1=http://192.168.216.130:2380,node2=http://192.168.216.132:2380,node3=http://192.168.216.134:2380" ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster" ETCD_INITIAL_CLUSTER_STATE="new"
修改 etcd.service
[[email protected] 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
启动 etcd
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 &
