EC2 Ubuntu - nginx：[emerg] 绑定（）到 0.0.0.0:80 失败（98：未知错误）

Question

运行

sudo nginx

命令后出现此错误

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Unknown error)
nginx: [emerg] bind() to [::]:80 failed (98: Unknown error)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Unknown error)

nginx: [emerg] bind() to [::]:80 failed (98: Unknown error)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Unknown error)
nginx: [emerg] bind() to [::]:80 failed (98: Unknown error)
nginx: [emerg] still could not bind()

这是我在 AWS EC2 上的安全设置：

在我的 Django 项目中，我为 nginx 创建了一个配置文件：(nginx.conf) （我还使用

uwsgi

作为第二个运行良好的网络服务器）

# the upstream components nginx needs to connect to
upstream dcohort {
        server unix:///tmp/dcohort.sock;
}

server {
        listen               80;
        listen               [::]:80;
        server_name          *.amazonaws.com;

        access_log off;
        error_log  /home/ubuntu/dcohort/logs/nginx_error.log;

        location / {
                include     /etc/nginx/uwsgi_params;
                uwsgi_pass  dcohort;
        }
}

然后将配置导入到

/etc/nginx/nginx.conf

http {
        include /home/ubuntu/dcohort/config/nginx.conf;
        # ...
}

您检查过/etc/nging/sites-enabled吗？它包含指向可用站点的链接，通常是由于您的配置冲突引起的错误，例如在不同的配置中多次使用端口 80，您应该删除或更新其中一个端口
