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-webui

3. 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;
1|{"version":0,"ui":{"default_locale":"","prompt_suggestions":[{"title":["Help me study","vocabulary for a college entrance exam"],"content":"Help me study vocabulary: write a sentence for me to fill in the blank, and I'll try to pick the correct option."},{"title":["Give me ideas","for what to do with my kids' art"],"content":"What are 5 creative things I could do with my kids' art? I don't want to throw them away, but it's also so much clutter."},{"title":["Tell me a fun fact","about the Roman Empire"],"content":"Tell me a random fun fact about the Roman Empire"},{"title":["Show me a code snippet","of a website's sticky header"],"content":"Show me a code snippet of a website's sticky header in CSS and JavaScript."},{"title":["Explain options trading","if I'm familiar with buying and selling stocks"],"content":"Explain options trading in simple terms if I'm familiar with buying and selling stocks."},{"title":["Overcome procrastination","give me tips"],"content":"Could you start by asking me about instances when I procrastinate the most and then give me some suggestions to overcome it?"},{"title":["Grammar check","rewrite it for better readability "],"content":"Check the following sentence for grammar and clarity: \"[sentence]\". Rewrite it for better readability while maintaining its original meaning."}],"enable_signup":false},"ollama":{"enable":true,"base_urls":["http://172.16.104.203:11434"],"api_configs":{"0":{}}},"openai":{"enable":false,"api_base_urls":["https://api.openai.com/v1"],"api_keys":[""],"api_configs":{"0":{}}}}|0|2025-04-14 08:07:08|2025-04-14 08:50:11.453672
sqlite> 
#-- 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
