下面由Laravel教程欄目給大家介紹Nacos 解決 laravel 多環(huán)境下配置切換的方法 ,希望對(duì)需要的朋友有所幫助！

前言

對(duì)于應(yīng)用程序運(yùn)行的環(huán)境來說，不同的環(huán)境有不同的配置通常是很有用的。例如，你可能希望在本地使用的緩存驅(qū)動(dòng)不同于生產(chǎn)服務(wù)器所使用的緩存驅(qū)動(dòng)。

痛點(diǎn)

• .env 配置不能區(qū)分多環(huán)境(開發(fā)，測(cè)試，生產(chǎn))
• .env 配置共享太麻煩(團(tuán)隊(duì)局域網(wǎng)環(huán)境)

• 配置不能實(shí)時(shí)管理，增刪改配置

• 自動(dòng)化部署配置 .env 文件過于繁瑣

Nacos 簡(jiǎn)介

Nacos 是阿里巴巴最新開源的項(xiàng)目，核心定位是 “一個(gè)更易于幫助構(gòu)建云原生應(yīng)用的動(dòng)態(tài)服務(wù)發(fā)現(xiàn)、配置和服務(wù)管理平臺(tái)”，項(xiàng)目地址：nacos.io/zh-cn/

應(yīng)用

這里主要使用了 Nacos 的配置管理，并沒有使用到動(dòng)態(tài)服務(wù)等功能。原理也很簡(jiǎn)單，通過接口直接修改 .env 文件。Nacos 服務(wù)可以直接使用使用阿里云提供的 應(yīng)用配置管理，無(wú)須安裝。鏈接如下: acmnext.console.aliyun.com/

使用示例

1. 注冊(cè)賬號(hào)，開通服務(wù)這些就不說了
2. .env 添加配置項(xiàng) NACOS_ACCESS_KEY NACOS_SECRET_KEY 等
3. php artisan nacos 0 獲取配置
4. php artisan nacos 1 發(fā)布配置
5. php artisan nacos 2 刪除配置

配置項(xiàng)說明

NACOS_ENDPOINT= #nacos節(jié)點(diǎn) 如使用阿里云服務(wù) 即:acm.aliyun.comNACOS_DATA_ID= #項(xiàng)目ID 可以填項(xiàng)目名NACOS_GROUP= #分組ID 這里可以用于區(qū)分環(huán)境 建議 local production test 等值NACOS_NAMESPACE= # 命名空間 建議用來區(qū)分服務(wù)器 server-A server-BNACOS_ACCESS_KEY= #阿里云access_key 建議使用子賬號(hào)access_keyNACOS_SECRET_KEY= #阿里云secret_key 建議使用子賬號(hào)secret_key

總結(jié)

使用 nacos 后，再也不用擔(dān)心 .env.example 忘記加配置項(xiàng)，共享配置也不是件麻煩事了，自動(dòng)部署也不需要頻繁的改動(dòng)配置了。
