Ubuntu 16.04，nginx，phpmyadmin-502坏网关

我将此设置用于nginx（默认文件）：

---

当我尝试访问30425时，我得到了502坏网关。所有其他设置都是默认设置（PHP7）。

我不得不替换这个fastcgi_pass 127.0.0.1:9000
要快速通过unix:/var/run/php/php7.3-fpm.sock； 然后它就完美地工作了

完整代码

server{
    listen 80;
    index index.html index.htm index.php;

    server_name 127.0.0.1;

    root /usr/share/phpmyadmin;
    location / {
            #try_files $uri $uri/ = 404;
            autoindex on;
    }


    location ~\.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+);
            try_files $uri $uri/ =404;
            fastcgi_pass unix:/var/run/php/php7.3-fpm.sock;
            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_na$
            fastcgi_param SERVER_NAME $http_host;
            fastcgi_ignore_client_abort on;
    }

}

所以打开日志并阅读它们。看看这个。。。与您的情况相同，从PHP7.3迁移到7.4，但没有更改fastscgi_-pass版本。非常感谢。
