1、在 K8s 中报错：504 Gateway Time-out nginx/1.17.8。请求超时限制为 60 秒。如图1
Plaintext
504 Gateway Time-out
nginx/1.17.8
3、新建一个 PHP 文件，运行时间超过 120 秒。curl http://127.0.0.1:81/1.php 未报错。如图2
PHP
<?php
sleep(120);
echo 1;
exit;
?>Plaintext
[root@main-6556cd6b98-jfqc9 public]# curl http://127.0.0.1:81/1.php

4、但是 curl https://morefun.xxx.xxx.cn/1.php 报错。如图3
Plaintext
[root@main-6556cd6b98-jfqc9 /]# curl https://morefun.xxx.xxx.cn/1.php

[root@main-6556cd6b98-jfqc9 /]# 5、在 Rancher 中 负载均衡 查看/编辑 YAML。如图4
6、参考网址：https://kubernetes.github.io/ingress-nginx/user-guide/nginx-configuration/annotations/#custom-timeouts 。添加 3 行 nginx.ingress 相关配置项。如图5
Plaintext
nginx.ingress.kubernetes.io/proxy-connect-timeout: "300"
nginx.ingress.kubernetes.io/proxy-read-timeout: "300"
nginx.ingress.kubernetes.io/proxy-send-timeout: "300"
7、curl https://morefun.xxx.xxx.cn/1.php 未报错。符合预期。步骤1响应504的问题也得到解决。如图6
