本文只涉及 Linux 上的安装。
二进制安装
- 下载二进制安装包
#ETCD_VER=v3.4.28
ETCD_VER=v3.5.10
DOWNLOAD_URL=https://github.com/etcd-io/etcd/releases/download
INSTALL_DIR=/tmp
rm -f ${INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz
rm -rf ${INSTALL_DIR}/etcd-download-test && mkdir -p /tmp/etcd-download-test
curl -L ${DOWNLOAD_URL}/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz -o ${INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz
下载地址示例:
https://github.com/etcd-io/etcd/releases/download/v3.5.10/etcd-v3.5.10-linux-amd64.tar.gz
- 解压二进制安装包
tar xzvf ${INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz -C ${INSTALL_DIR}/etcd-download-test --strip-components=1
- 删除二进制安装包
rm -f ${INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz
- 版本检查
${INSTALL_DIR}/etcd-download-test/etcd --version
${INSTALL_DIR}/etcd-download-test/etcdctl version
- 启动 etcd
${INSTALL_DIR}/etcd-download-test/etcd
- 往 etcd 写读数据
${INSTALL_DIR}/etcd-download-test/etcdctl --endpoints=localhost:2379 put foo bar
${INSTALL_DIR}/etcd-download-test/etcdctl --endpoints=localhost:2379 get foo
Docker 安装

etcd 主要使用 Google 容器注册表(gcr.io)下的 gcr.io/etcd-development/etcd 仓库来存储其容器镜像。作为次要选项,它还使用 Quay.io 下的 quay.io/coreos/etcd 仓库。这两个注册表都提供 etcd 容器镜像,可用于在类似 Kubernetes 的容器化环境中部署 etcd。

使用证书
假设 CACert 证书文件为 etcd-6ecm89rt-CAcert,Cert 证书文件为 etcd-6ecm89rt-Cert,私钥文件为 etcd-6ecm89rt-Key,etcd 的访问地址为 https://192.168.10.17:2023,取 key 为 foo 的值:文章来源地址https://www.toymoban.com/news/detail-757070.html
etcdctl --endpoints=https://192.168.10.17:2023 \
--cacert=etcd-6ecm89rt-CAcert \
--cert=etcd-6ecm89rt-Cert \
--key=etcd-6ecm89rt-Key \
get foo
