Dify报错502 Bad gateway解决方案

找到docker-api-1的ip地址

注意：如果有多个ip，选择其中任意一个即可。

docker inspect --format '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' docker-api-1

196.128.0.8196.128.0.4

找到docker-web-1的ip地址

注意：如果有多个ip，选择其中任意一个。

docker inspect --format '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' docker-web-1

196.128.0.6

修改nginx配置文件

vim ${DIFY_HOME}/docker/nginx/conf.d/default.conf
vim ${DIFY_HOME}/docker/nginx/conf.d/default.conf.template

将default.conf和default.conf.template中的http://api:5001替换为http://196.128.0.8:5001，将http://web:3000替换为http://196.128.0.6:3000。

server {
    listen 80;
    server_name _;
    location /console/api {
      proxy_pass http://api:5001;  # 改为proxy_pass http://196.128.0.8:5001;
      include proxy.conf;
    }
    location /api {
      proxy_pass http://api:5001; # 改为proxy_pass http://196.128.0.8:5001;
      include proxy.conf;
    }
    location /v1 {
      proxy_pass http://api:5001; # 改为proxy_pass http://196.128.0.8:5001;
      include proxy.conf;
    }
    location /files {
      proxy_pass http://api:5001; # 改为proxy_pass http://196.128.0.8:5001;
      include proxy.conf;
    }
    location / {
      proxy_pass http://web:3000; # 改为proxy_pass http://196.128.0.6:5001;
      include proxy.conf;
    }
    # placeholder for acme challenge location
    
    # placeholder for https config defined in https.conf.template
    
}

修改.env文件

vim ${DIFY_HOME}/docker/.env

确认EXPOSE_NGINX_PORT=80，与${DIFY_HOME}/docker/nginx/conf.d/default.conf中listen指定的端口一致。

加载nginx配置

# 进入容器
docker exec -it docker-nginx-1 bash
# 加载配置
sbin/nginx -s reload
