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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

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

?
