php - Ngnix + Apache/php-frm 502 网关错误

Question

尝试在两个不同的服务器上设置 Nginx 作为反向代理和 Apache 2.4.37 / php-frm 7.4.7。收到 502 bad gateway 错误消息，这是 Nginx 服务器的日志。

2021/08/16 15:40:27 [错误] 6550#0: *18 connect() 在连接到上游时失败（111：连接被拒绝），客户端：192.168.0.100，服务器：aaa.bbb，请求：“GET /wp-admin/admin.php?page=followup-emails HTTP/1.1”，上游：“fastcgi://10.0.0.35:9001”，主机：“aaa.bbb”，推荐人：“https://aaa. bbb/wp-admin/"

Nginx 上的配置：10.0.0.41

server {

在 Apache 上配置，10.0.0.35

<VirtualHost *:80>
   ServerName aaa.bbb
   DocumentRoot /var/www/staging/public_html
   LimitRequestFieldSize 1000000000
   LimitRequestLine 1000000000

        <IfModule proxy_fcgi_module>
        <Proxy "fcgi://127.0.0.1:9001/" enablereuse=on max=50>
         ProxySet timeout=1800
        </Proxy>
        <FilesMatch "\.php$">
        <If "-f %{REQUEST_FILENAME}">
            SetHandler "proxy:fcgi://127.0.0.1:9001"
        </If>
        </FilesMatch>
        </IfModule>

</VirtualHost>

网络统计-an | grep :9001 tcp 0 0 127.0.0.1:9001 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:9001 127.0.0.1:38312 已建立

有什么线索吗？
