Php 502坏网关nginx/1.19.1

我已经安装了

nginx版本：nginx/1.19.1

，

php7.4.8（fpm-fcgi）

和

php7.4.8（cli）

我的nginx服务器块配置：

我测试它的“给我”错误

Nginx日志错误：

给我权限被拒绝了，所以

为什么会发生这种情况？

要花很多时间来解决

我通过将etc/nginx/nginx.conf{user nginx}更改为{user www data}来解决其实际权限问题，然后保存并重新启动nginx（sudo systemctl restart nginx）。

user  www-data;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/sites-enabled/*;
}

我还不能发表评论，所以我写这篇文章作为回答。 你所做的只是一种方式。 另一种方法是在

/etc/php/7.4/fpm/pool.d/www.conf

中更改用户：

user = nginx
group = nginx
listen.owner = nginx
listen.group = nginx

就个人而言，我更喜欢为php fpm更改用户，而不是为nginx更改用户

干杯。

套接字

/var/run/php/php7.4-fpm.sock

是否存在？Nginx是否有访问权限？是，套接字存在

user  www-data;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/sites-enabled/*;
}

user = nginx
group = nginx
listen.owner = nginx
listen.group = nginx
