windows安装

linux安装

源码安装

yum安装

版本一般比较老

docker命令安装

确认有docker环境

docker run --name etcd -d -p 2379:2379 -p 2380:2380 -e ALLOW_NONE_AUTHENTICATION=yes bitnami/etcd:3.3.11 etcd 

docker-compose安装

确认有docker-compose 环境

docker-compose.yaml

version: "3"
services:
  etcd:
    container_name: etcd
    hostname: etcd
    image: bitnami/etcd:3
    deploy:
      replicas: 1
      restart_policy:
        condition: on-failure
    # ports:
    #   - "2379:2379"
    #   - "2380:2380"
    #   - "4001:4001"
    #   - "7001:7001"
    privileged: true
    volumes:
      - "~/DockerConfig/etcd/data:/bitnami/etcd/data"
    environment:
      - "ETCD_ADVERTISE_CLIENT_URLS=http://0.0.0.0:2379"
      - "ETCD_LISTEN_CLIENT_URLS=http://0.0.0.0:2379"
      - "ETCD_LISTEN_PEER_URLS=http://0.0.0.0:2380"
      - "ETCD_INITIAL_ADVERTISE_PEER_URLS=http://0.0.0.0:2380"
      #参数指不用密码可以连接
      - "ALLOW_NONE_AUTHENTICATION=yes"
      - "ETCD_INITIAL_CLUSTER=node1=http://0.0.0.0:2380"
      - "ETCD_NAME=node1"
      - "ETCD_DATA_DIR=/opt/bitnami/etcd/data"
    ports:
      - 2379:2379
      - 2380:2380
    networks:
      - etcdnet
  etcdkeeper:
    image: deltaprojects/etcdkeeper
    container_name: etcdkeeper
    ports:
      - 8088:8080
    networks:
      - etcdnet 
networks:
  etcdnet:
    name: etcdnet

启动服务

docker-compose up -d

向etcd写入数据

docker exec -it etcd /bin/bash
etcdctl set /name haima4
etcdctl get /name

访问 etcdkeeper

etcdkeeper 查看数据
http://192.168.2.47:8088/etcdkeeper/

打开后连接服务地址

192.168.2.47:2379 # 宿主主机地址加端口号
或者 etch的容器名称加端口号
etcd:2379 # etch的容器名称

以上都了是在etcdkeeper容器内可以访问到的etcd服务地址

常用操作

// 设置或更新值
etcdctl put name 张三
// 获取值
etcdctl get name
// 只要value
etcdctl get name --print-value-only
// 获取name前缀的键值对
etcdctl get --prefix name
// 获取所有的键值对
etcdctl get "" --from-key
// 删除键值对
etcdctl del name
// 监听键的变化
etcdctl watch name
