1.下载

2.将压缩文件解压到指定文件夹

解压后的目录如下:

\

其中etcd.exe是服务端,etcdctl.exe是客户端

二、简单实用

1.点击etcd.exe运行etcd服务

2.客户端是有etcdctl来执行命令的

1)帮助文档

\

在安装目录命令提示符中执行 etcdctl help 可以查看etcdctl的基本命令如下:

NAME:

etcdctl - A simple command line client for etcd.

USAGE:

etcdctl [global options] command [command options] [arguments...]

COMMANDS:

backup backup an etcd directory

cluster-health check the health of the etcd cluster

mk make a new key with a given value

mkdir make a new directory

rm remove a key or a directory

rmdir removes the key if it is an empty directory or a key-value pair

get retrieve the value of a key

ls retrieve a directory

set set the value of a key

setdir create a new directory or update an existing directory TTL

update update an existing key with a given value

updatedir update an existing directory

watch watch a key for changes

exec-watch watch a key for changes and exec an executable

user user add, grant and revoke subcommands

role role add, grant and revoke subcommands

help, h Shows a list of commands or help for one command

GLOBAL OPTIONS:

--debug output cURL commands which can be used to reproduce the request

--no-sync don't synchronize cluster information before sending request

--output simple, -o simple output response in the given format (simple, `extended` or `json`) (default: "simple")

--discovery-srv value, -D value domain name to query for SRV records describing cluster endpoints

--insecure-discovery accept insecure SRV records describing cluster endpoints

--peers value, -C value DEPRECATED - "--endpoints" should be used instead

--endpoint value DEPRECATED - "--endpoints" should be used instead

--endpoints value a comma-delimited list of machine addresses in the cluster (default: "http://127.0.0.1:2379,http://127.0.0.1:4001")

--help, -h show help

--version, -v print the version

2)查看版本号 etcdctl --version

\

3)由于文档中建议API version的版本设为3

设置版本set ETCDCTL_API=3

\

即可设置API version,设置成功后etcdctl help查看版本3和2命令和功能方面有不少的差别

3)通过put和get 存取值

\

存取key为hello,value为world

\

获取key为hello的值
