 proxy_pass        http://127.0.0.1:8191/server-front/;  这个直接跳转到server-front端口试试先

 proxy_pass        http://127.0.0.1:18082 类似这样

http://120.71.4.179:8191/server-front，也出不来

您把这个 / 代理到 http://120.71.4.179:18082  server-front的端口

回复第5楼
能写具体一点吗？示列代码给一下。server-front没有开这个端口18082

http://120.71.4.179:18002  这个也访问不了，那就看下server-front 的日志吧，看看提示什么

2023/12/06 17:56:48 [crit] 1856#0: *202 open() "/usr/local/nginx/logs/2023-12-06-TYJSsite-access.log" failed (13: Permission denied) while logging request, client: 218.84.72.86, server: 192.168.0.232, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8191/server-front/", host: "120.71.4.179"

nginx日志，这块问题出在哪里？怎么修改

server-front，日志也没有报错啊

配置文件application，prod，redis3个也没有设置模板文件的配置，是这个问题吗？

配置文件application，prod，redis 设置模板文件的配置，配置错了。现在白屏，如何处置？
