nginx err_connection_refused，有人可以帮助我吗？

如何解决nginx err_connection_refused，有人可以帮助我吗？

用php，mysql等安装了旧站点，一切正常，但无法从LAN外部访问我的站点。做了大量的更改，并为启用了Nginx网站和php7.4尝试了至少100次配置，但没有任何帮助：/。我收到502或连接被拒绝的错误。在ubuntu 20.04上运行

检查此默认容器：

    server {
    listen 80; 
    root /var/www; 
    index index.html index.php index.htm index.nginx-debian.html;
    server_name localhost;
    location / {
        try_files $uri $uri/ =404;
    }
    
location ~ [^/]\.php(/|$) {
    fastcgi_split_path_info ^(.+?\.php)(/.*)$;
    #fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
    fastcgi_pass 127.0.0.1:9000;
    include snippets/fastcgi-php.conf;  
        #fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
}
}

和php www.conf（均已测试）：

...
;listen = /var/run/php/php7.4-fpm.sock
listen = 0.0.0.0:9000
...

netstat -lntp：

你们有什么暗示吗，我可能会错过吗？

最诚挚的问候和抱歉，我的英语不好

解决方法

使用错误日志配置文件，例如：

server {
error_log /path/server.error.log;

listen 80; 
root /var/www; 
index index.html index.php index.htm index.nginx-debian.html;
server_name local...

然后，重新启动nginx并检查server.error.log文件。 通过这些更改，您可以了解正在发生的事情，

它看起来像nginx don t see yuor php-fpm so,FIND php-fpm on harddisk and try put the pass into nginx.conf as fastcgi_pass to make it looks like: fastcgi_pass Unix：/ var / run / php / php7。*-fpm.sock;`

,

sudo tail -f /var/log/php7.*-fpm.log
ngnix.conf => php-fpm socet?
location ~ \.php$ {
fastcgi_pass unix:/var/run/php7.0-fpm.sock;
include fastcgi_params;
} 

https://saribzhanov.ru/tehno/nastraivaem-rabotu-php-fpm-na-port-ili-na-soket/ 位置/ { ...

location ~ [^/]\.php(/|$) {
    ...

    fastcgi_pass    127.0.0.1:9000;
    fastcgi_index   index.php;
    include         /etc/nginx/fastcgi_params;
}

} 但是

netstat -tulpn | grep 9000

... /etc/php/7.3/fpm/pool.d/www.conf =>听= 127.0.0.1:9000

/etc/php/7.3/fpm/pool.d/www.conf =>听= /var/run/fastcgi.sock

listen.allowed_clients = 127.0.0.1 =>未出现

和在nginx.conf中 位置 / { ...

location ~ [^/]\.php(/|$) {
    ....

    fastcgi_pass    unix:/var/run/php/php7.3-fpm.sock;
    fastcgi_index   index.php;
    include         /etc/nginx/fastcgi_params;
}

} 看看“ fastcgi_pass” nginx.conf 位置 / { fastcgi_pass Unix：/var/run/php/php7.3-fpm.sock; //127.0用php7。*-fpm.sock替换！看起来像nginx看不到php-fpm
