92 | 部署到 Zeabur 93 |
94 | 95 | [![Deployed on Zeabur](https://zeabur.com/deployed-on-zeabur-dark.svg)](https://zeabur.com?referralCode=deanxv&utm_source=deanxv) 96 | 97 | > Zeabur 的服务器在国外,自动解决了网络的问题,~~同时免费的额度也足够个人使用~~ 98 | 99 | 1. 首先 **fork** 一份代码。 100 | 2. 进入 [Zeabur](https://zeabur.com?referralCode=deanxv),使用github登录,进入控制台。 101 | 3. 在 Service -> Add Service,选择 Git(第一次使用需要先授权),选择你 fork 的仓库。 102 | 4. Deploy 会自动开始,先取消。 103 | 5. 添加环境变量 104 | 105 | `API_SECRET:123456` [可选]接口密钥-修改此行为请求头校验的值(多个请以,分隔)(与openai-API-KEY用法一致) 106 | 107 | 保存。 108 | 109 | 6. 选择 Redeploy。 110 | 111 |
112 | 113 | 114 |
115 | 116 |
117 | 部署到 Render 118 |
119 | 120 | > Render 提供免费额度,绑卡后可以进一步提升额度 121 | 122 | Render 可以直接部署 docker 镜像,不需要 fork 仓库:[Render](https://dashboard.render.com) 123 | 124 |
