解决docker安装OpenWebUI 报错 500
你在访问 Web UI 时遇到 500 错误，可能是由于以下几个原因导致的：
1. OpenAI 配置冲突
从配置中可以看到：
json
"openai": {"enable": true, // 开启"api_base_urls": ["https://api.openai.com/v1"],"api_keys": [""], // 密钥为空"api_configs": {"0":{}}
}
当 openai.enable=true 时，系统会尝试调用 OpenAI 的接口，但你的 api_keys 为空，会导致服务端认证失败。
如果服务端没有正确处理空密钥的情况，会直接抛出 500 错误。
2.解决方案：
如果不需要 OpenAI 功能，保持 enable: false。
"openai": {"enable": false, // 已被你禁用"api_base_urls": ["https://api.openai.com/v1"],"api_keys": [""], // 密钥为空"api_configs": {"0":{}}
}
如果需要 OpenAI，需填写有效的 API 密钥：
json
"openai": {"enable": true,"api_keys": ["sk-your-api-key-here"] // 替换为有效密钥
}
3.关闭OpenAI 功能解决办法
1. 查看容器挂载详情
[root@koji-builder ~]# docker inspect open-webui | grep -A 10 "Mounts""Mounts": [{"Type": "volume","Name": "open-webui","Source": "/var/lib/docker/volumes/open-webui/_data","Destination": "/app/backend/data","Driver": "local","Mode": "z","RW": true,"Propagation": ""}
[root@koji-builder ~]# 2.定位文件位置
[root@koji-builder ~]# cd /var/lib/docker/volumes/open-webui/_data
[root@koji-builder _data]# ls
cache uploads vector_db webui.db
[root@koji-builder _data]# 2. 修改修改 config 表中 openai.enable 字段
如果不修改的话，会报500，因为openwebui使用了openai的api，如果不能访问外网的情况下，需要修改数据库表的openai.enable 字段
1.安装sqlite
yum install sqlite
2.备份数据库和停止 Open WebUI 容器
sudo cp webui.db webui.db.bak
#停止 Open WebUI 容器
docker stop open-webui3. 进入 SQLite 交互模式
[root@koji-builder _data]# sqlite3 webui.db
SQLite version 3.26.0 2018-12-01 12:34:55
Enter ".help" for usage hints.
sqlite>
4. 查看所有表，是否有config 表
sqlite> .tables
alembic_version config group model
auth document knowledge prompt
channel feedback memory tag
channel_member file message tool
chat folder message_reaction user
chatidtag function migratehistory
sqlite> 5. 修改config 表"openai":{"enable"是的修改true
#修改
sqlite> UPDATE config ...> SET data = json_set(...> data, ...> '$.openai.enable', ...> json('false') ...> ) ...> WHERE id = 1;
#-- 验证结果
sqlite> SELECT json_extract(data, '$.openai.enable') FROM config WHERE id = 1;
0
6. 查看config 表中的"openai":{"enable"是的修改false
sqlite> select * from config;

#-- 退出
sqlite> .quit
7. 重启open-webui容器
[root@koji-builder _data]# docker start open-webui
open-webui
如果启动后没有反应需要进容器里启动
[root@koji-builder _data]# docker exec -it open-webui /bin/bash
root@69d9b2ad6b44:/app/backend# ls
data dev.sh open_webui requirements.txt start.sh start_windows.bat
root@69d9b2ad6b44:/app/backend# ./start.sh 3. 访问open-webui
http://ip:3000
