我刚刚选择 nginx 作为我的网络服务器，并且我确实遵循了本教程：https://github.com/groovemonkey/hands_on_linux-self_hosted_wordpress_for_linux_beginners

但是，我无法连接到我的网络服务器。

当我这样做时，$ sudo nginx我得到以下回复：

nginx: [warn] duplicate MIME type "text/html" in /etc/nginx/nginx.conf:34
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

$ sudo netstat -plten | grep 80给出以下结果：

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      0          70851       9943/nginx -g daemo
tcp6       0      0 :::80                   :::*                    LISTEN      0          70850       9943/nginx -g daemo

这是我的 nginx.conf：

user  www-data;
worker_processes  auto;

pid /run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       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"';
    error_log  /var/log/nginx_error.log error;
    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # no sslv3 (poodle etc.)
    ssl_prefer_server_ciphers on;

    # Gzip Settings
    gzip on;
    gzip_disable "msie6";
    gzip_vary on;
    gzip_min_length 512;
    gzip_types text/plain text/html application/x-javascript text/javascript application/javascript text/xml text/css application/font-sfnt;

    fastcgi_cache_path /usr/share/nginx/cache/fcgi levels=1:2 keys_zone=microcache:10m max_size=1024m inactive=1h;

    include /etc/nginx/conf.d/*.conf;
    #include /etc/nginx/sites-enabled/*;
}

这是我的 site.conf （位于 /etc/nginx/conf.d/ 中）：

系统是Linux Mint 18.3 Sylvia。

现在 nginx 能够绑定端口（忘记替换 default.conf），但我仍然收到 Connection Refused 的消息。这与 PHP/FastCGI 有关吗？

答案1

只需尝试终止或终止现有的 nginx 进程即可。并重新开始。现在您已经有了以守护进程模式运行的 nginx 进程。并且这个进程阻塞了80端口。
