php - nginx 和 php-fpm 502 错误

Question

我为这个问题寻找了许多解决方案。但是，他们都没有帮助我解决它。/var/log/nginx/error.log 中显示的错误如下:

2017/04/21 16:08:16 [error] 29233#0: *319 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: ..., server: ..., request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "..."

Nginx 配置如下:

server {

    listen 443;
    server_name ... ...;

    ssl on;
    ssl_certificate /etc/nginx/ssl/....cer;
    #ssl_client_certificate /etc/nginx/ssl/....cer;
    ssl_certificate_key /etc/nginx/ssl/....key;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2; 

    root /var/www/drupal7; ## <-- Your only path reference.

    location = /favicon.ico {

    }

    location = /robots.txt {
            allow all;
            log_not_found off;

    }

    location / {

    }

    location /adore-djatoka {

#            proxy_redirect http://...:8080/adore-djatoka /adore-djatoka;
            #proxy_redirect off;
    }

    location @rewrite {
            # You have 2 options here
            # For D7 and above:
            # Clean URLs are handled in drupal_environment_initialize().
            rewrite ^ /index.php;
            # For Drupal 6 and bwlow:
            # Some modules enforce no slash (/) at the end of the URL
            # Else this rewrite block wouldn't be needed (GlobalRedirect)
            #rewrite ^/(.*)$ /index.php?q=$1;
    }

    # For Munin
    location /nginx_status {
            stub_status on;
            access_log off;
            allow 127.0.0.1;
            deny all;
    }

    location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_intercept_errors on;
            fastcgi_pass 127.0.0.1:9000;
            #fastcgi_pass php-fpm;
    }

    # Fighting with Styles? This little gem is amazing.
    # This is for D7 and D8
    location ~ ^/sites/.*/files/styles/ {
            try_files $uri @rewrite;
    }

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
            expires max;
            log_not_found off;
    }

}

如果需要，我也可以发布 php-fpm 配置文件。

谢谢，

试试 替换 你的 PHP 块

location ~ \.php$ {
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    #NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $request_filename;
    fastcgi_intercept_errors on;
    fastcgi_pass 127.0.0.1:9000;
    #fastcgi_pass php-fpm;
}

通过这个，取决于你的 PHP 版本，
对于 PHP 5 :

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php5-fpm.sock;
}

或为 PHP 7 :

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
}

对于 PHP 7.4

location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}

等等等等。您可以随时查看 sock可在 /run/php/ 中找到:

ls -la /run/php

然后只需在 Nginx 配置中指定要使用的版本。
不要忘记在这些配置更改后重新启动/重新加载 nginx(以 root 身份):

# check for config errors
nginx -t

# make sure the command above doesn't yield any errors.
# Then reload nginx
service nginx reload
