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 ,希望對需要的朋友有所幫助！

前言

對于應用程序運行的環(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動不同于生產服務器所使用的緩存驅動。

痛點

• .env 配置不能區(qū)分多環(huán)境(開發(fā)，測試，生產)
• .env 配置共享太麻煩(團隊局域網環(huán)境)

• 配置不能實時管理，增刪改配置

• 自動化部署配置 .env 文件過于繁瑣

Nacos 簡介

Nacos 是阿里巴巴最新開源的項目，核心定位是 “一個更易于幫助構建云原生應用的動態(tài)服務發(fā)現(xiàn)、配置和服務管理平臺”，項目地址：nacos.io/zh-cn/

應用

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

使用示例

1. 注冊賬號，開通服務這些就不說了
2. .env 添加配置項 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

配置項說明

NACOS_ENDPOINT= #nacos節(jié)點 如使用阿里云服務 即:acm.aliyun.comNACOS_DATA_ID= #項目ID 可以填項目名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)分服務器 server-A server-BNACOS_ACCESS_KEY= #阿里云access_key 建議使用子賬號access_keyNACOS_SECRET_KEY= #阿里云secret_key 建議使用子賬號secret_key

總結

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