解决docker安装OpenWebUI 报错 500_500: open webui: server connection error
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]# lscache 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 sqlite2.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 12:34:55Enter \".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;06. 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?

[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/bashroot@69d9b2ad6b44:/app/backend# lsdata dev.sh open_webui requirements.txt start.sh start_windows.batroot@69d9b2ad6b44:/app/backend# ./start.sh 3. 访问open-webui
