增加504超时错误

根据你所使用的网关类型，你应该使用以下这些东西:

proxy_read_timeout 600s;

检查文件: http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_read_timeout

如果是 fastcgi超时错误，则需要增加 fastcgi_read_timeout。

# /etc/nginx/conf.d/example.com.conf
server {


location ~ \.(php)$ {
fastcgi_pass unix:/var/run/php74-example.com.sock;
fastcgi_read_timeout 300s;

上游超时

# tail -f example.com.error.log
