    这是一个创建于 572 天前的主题,其中的信息可能已经有所发展或是发生改变。

    手贱重启了 openresty,突然站点就 403 forbidden。搞了一天了,真心累,请教同学们。

    配置环境:centos7+openresty(nginx)+php+mysql systemctl status openresty ,systemctl status php-fpm,systemctl status mysql,都是 active status,绿色。

    1. 给 server 那段单独写一个 error_log
    2. 试试把 WAF 相关的配置先注释掉

    看一下 nginx 有没有 web 根路径的读权限,如果有,在根路径下创建一个 xxxx.php 文件,里面随便输出点字符串,然后访问,看能否访问,能,说明你站点 php 逻辑问题,不能,nginx 问题,通过日志把问题,还是找不到,直接上 strace

    livid 的办法是正解。

    开 error_log,debug 级别。就能看到为啥出错了。

    你这边怎么又是 403,另一个帖子 502。listen 127.0.0.1,你是直接 在本地 curl 127.0.0.1 出现 403/502 ?
    如果是访问你的站点的公网地址,前面那一层怎么访问 127.0.0.1 ?
