goreman搭建etcd——分布式

以你之姓@ 2023-06-25 08:27 6阅读 0赞

本文主要介绍如何使用goreman搭建etcd的本地伪分布式。

首先需要了解goreman的使用，一个能够根据指定文件启动多个进程的工具。参考这里：

好，下面上货。

主要参考：

编写Procfile.learner文件

# Use goreman to run `go get github.com/mattn/goreman`
    # Change the path of bin/etcd if etcd is located elsewhere
    
    etcd1: etcd --name infra1 --listen-client-urls http://127.0.0.1:2379 --advertise-client-urls http://127.0.0.1:2379 --listen-peer-urls http://127.0.0.1:12380 --initial-advertise-peer-urls http://127.0.0.1:12380 --initial-cluster-token etcd-cluster-1 --initial-cluster 'infra1=http://127.0.0.1:12380,infra2=http://127.0.0.1:22380,infra3=http://127.0.0.1:32380' --initial-cluster-state new --enable-pprof
    etcd2: etcd --name infra2 --listen-client-urls http://127.0.0.1:22379 --advertise-client-urls http://127.0.0.1:22379 --listen-peer-urls http://127.0.0.1:22380 --initial-advertise-peer-urls http://127.0.0.1:22380 --initial-cluster-token etcd-cluster-1 --initial-cluster 'infra1=http://127.0.0.1:12380,infra2=http://127.0.0.1:22380,infra3=http://127.0.0.1:32380' --initial-cluster-state new --enable-pprof
    etcd3: etcd --name infra3 --listen-client-urls http://127.0.0.1:32379 --advertise-client-urls http://127.0.0.1:32379 --listen-peer-urls http://127.0.0.1:32380 --initial-advertise-peer-urls http://127.0.0.1:32380 --initial-cluster-token etcd-cluster-1 --initial-cluster 'infra1=http://127.0.0.1:12380,infra2=http://127.0.0.1:22380,infra3=http://127.0.0.1:32380' --initial-cluster-state new --enable-pprof
    #proxy: bin/etcd grpc-proxy start --endpoints=127.0.0.1:2379,127.0.0.1:22379,127.0.0.1:32379 --listen-addr=127.0.0.1:23790 --advertise-client-url=127.0.0.1:23790 --enable-pprof
    
    # A learner node can be started using Procfile.learner

然后执行

goreman -f ./Procfile.learner start

查看端口情况

尝试读写 ok

连接到集群其他节点上并且读取

其实从这里已经能够看出，etcd和zookeeper解决的问题类似，同时，etcd在启动时候的日志也表明了节点之间的关系是通过选举产生的。
