- Linux Docker 安装Dify本地运行，及部署后运行出现502问题
- Docker 部署Nginx遇到502解决方法之一（需关闭防火墙）
- Dify最新版本安装问题解决（接口/console/api/setup返回502错误）
- 本地部署Dify版本升级过程（官方vs乾坤大挪移）
启动
cd /data/dify/docker docker compose up -d
关闭

查看Nginx等错误日志：
docker logs docker-nginx-1 | grep errors docker logs docker-api-1 | grep errors docker logs docker-web-1 | grep errors docker logs docker-sandbox-1 | grep errors
个人本次502错误的解决方案：
(1)关闭防火墙
service firewalld stop
(2)重启docker
systemctl restart docker
