傳統(tǒng)配置文件的弊端

靜態(tài)化配置，例如env文件配置文件無(wú)法區(qū)分環(huán)境配置文件過(guò)于分散歷史版本無(wú)法查看

配置中心如何解決的呢?配置中心的思路是把項(xiàng)目中的配置參數(shù)全部放在一個(gè)集中的地方來(lái)管理，并提供一套標(biāo)準(zhǔn)的接口，當(dāng)各個(gè)服務(wù)需要獲取配置的時(shí)候就來(lái)拉取信息，當(dāng)配置中心有更新的時(shí)候，也能通知其他服務(wù)，實(shí)時(shí)同步最新消息。

微服務(wù)配置中心

配置信息的管理配置信息的查看、讀取、更新等，完善的Api管理界面高可用、權(quán)限管理等功能

主流的配置中心

Apollo是由攜程開(kāi)源的分布式配置中心Spring Cloud ConfigConsul

Consul 配置操作

1.添加配置信息

2.獲取配置信息

GET http://192.168.88.144:8500/v1/kv/mic/pro/pro[    {        "LockIndex":0,        "Key":"mic/pro/pro",        "Flags":0,        "Value":"ewoJImhvc3QiOiIxMjcuMC4wLjEiLAogICJwcm90IjogMzMwNiwKICAidXNlciI6InRlc3QiLAogICJwd2QiOiIxMjcuMC4wLjEiCn0=",        "CreateIndex":473,        "ModifyIndex":473    }]

單點(diǎn)服務(wù)器Consul集群

補(bǔ)充一下單點(diǎn)服務(wù)器Consul集群的步驟，我的虛擬機(jī)ip 192.168.88.144,配置3個(gè)節(jié)點(diǎn), Consul v1.12.1

server01@server01-virtual-machine:~$ consul versionConsul v1.12.1
wget https://releases.hashicorp.com/consul/1.12.1/consul_1.12.1_darwin_arm64.zipunzip consul_1.12.1_darwin_arm64.zipmv consul /usr/local/bin/consul
