1.下载并安装etcd
ETCD_VERSION='3.4.13'
wget https://github.com/etcd-io/etcd/releases/download/v${ETCD_VERSION}/etcd-v${ETCD_VERSION}-linux-amd64.tar.gz
tar -xvf etcd-v${ETCD_VERSION}-linux-amd64.tar.gz
mv etcd-v${ETCD_VERSION}-linux-amd64 /opt/etcd
cp -a /opt/etcd/etcd /opt/etcd/etcdctl /usr/bin/
2.创建需要用到的目录
mkdir -p /opt/etcd/data mkdir -p /var/lib/etcd/ mkdir -p /etc/etcd/config/
3.编写配置文件
cat > /etc/etcd/config/etcd.conf <<EOF name: etcd data-dir: /opt/etcd/data listen-peer-urls: http://127.0.0.1:6677 listen-client-urls: http://0.0.0.0:7777 advertise-client-urls: http://127.0.0.1:7777 initial-advertise-peer-urls: http://10.1.1.7:2380 initial-cluster: etcd-1=http://127.0.0.1:2380 initial-cluster-token: etcd-cluster initial-cluster-state: new enable-grpc-gateway: true EOF
4.编写服务文件
cat > /etc/systemd/system/etcd.service <<EOF [Unit] Description=Etcd Server Documentation=https://github.com/coreos/etcd After=network.target [Service] User=root Type=notify ExecStart=/opt/etcd/etcd --config-file /etc/etcd/config/etcd.conf Restart=on-failure RestartSec=10s LimitNOFILE=40000 [Install] WantedBy=multi-user.target EOF
5.配置开机自启并启动
systemctl daemon-reload systemctl enable etcd systemctl restart etcd
