操作系统:Funtoo。我已将 NGINX 绑定到端口 81(我想在短时间内将它与我的 Apache 服务器一起运行,以便于转换),并且它侦听该端口(如果我指向另一个端口,使用 wget 我会收到“连接被拒绝”,但使用端口 81 我得到了“连接”),但它从不提供任何类型的 HTML 响应!
当从本地主机在端口上运行 wget 时,我得到:
# wget localhost:81
-2014-04-16 23:56:45- http://localhost:81/
Resolving localhost... 127.0.0.1
Connecting to localhost|127.0.0.1|:81... connected.
HTTP request sent, awaiting response...
在另一台电脑上...
$ wget 192.168.18.42:81
-2014-04-16 23:57:19- http://192.168.18.42:81/
Connecting to 192.168.18.42:81... connected.
HTTP request sent, awaiting response...
此后什么也没有发生。文件是存在的,就是正常的Funtoo nginx.conf。
更新:我可以让它监听端口 80,但它仍然让我感到不安,因为我无法让它在任何端口上工作......
netstat -aWn | grep 81 | grep LISTEN
tcp 60 0 0.0.0.0:81 0.0.0.0:* LISTEN
编辑:配置文件:
user nginx nginx;
worker_rlimit_nofile 6400;
error_log /var/log/nginx/error_log info;
events {
worker_connections 1024;
use epoll;
}
http {
include /etc/nginx/mime.types;
# This causes files with an unknown MIME type to trigger a download action in the browser:
default_type application/octet-stream;
log_format main
'$remote_addr - $remote_user [$time_local] '
'"$request" $status $bytes_sent '
'"$http_referer" "$http_user_agent" '
'"$gzip_ratio"';
client_max_body_size 64m;
# Don't follow symlink if the symlink's owner is not the target owner.
disable_symlinks if_not_owner;
server_tokens off;
ignore_invalid_headers on;
gzip off;
gzip_vary on;
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript text/x-js image/x-icon image/bmp;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
index index.html;
include /etc/nginx/sites-enabled/*;
}
服务器块:
server {
listen *:81;
root /usr/share/nginx/html;
location / {
index index.html;
}
}
答案1
尝试以下服务器块:
server {
listen 81 default_server;
server_name _;
root /usr/share/nginx/html;
location / {
index index.html;
}
}
下划线_
是通配符,而且*:81
可能不会执行您所期望的操作,只需使用端口号即可。
然后使用以下命令测试您的设置nginx -t
:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
重启nginx:
service nginx restart
使用netstat测试:
root@gitlab:~# netstat -napl | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 7903/nginx
tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN 2662/unicorn.
更新
我在测试系统上安装了 nginx。通过 stocknginx.conf
文件并将 1 行更改为/etc/nginx/sites-enabled/default
,我能够从端口 81 检索文件
cat /etc/nginx/sites-enabled/default
server {
listen 81;
server_name localhost;
root /usr/share/nginx/www;
index index.html index.htm;
location / {
try_files $uri $uri/ /index.html;
}
location /doc/ {
alias /usr/share/doc/;
autoindex on;
allow 127.0.0.1;
deny all;
}
}
网络统计输出:
netstat -napl | grep 81
tcp 0 0 0.0.0.0:81 0.0.0.0:* LISTEN 3432/nginx
下载文件:
$ wget localhost:81
文件内容:
$ cat index.html
<html>
<head>
<title>Welcome to nginx!</title>
</head>
<body bgcolor="white" text="black">
<center><h1>Welcome to nginx!</h1></center>
</body>
</html>
更新2
测试端口:
root@gitlab:# nc -vz localhost 81
Connection to localhost 81 port [tcp/*] succeeded!
root@gitlab:# nc -vz localhost 443
nc: connect to localhost port 443 (tcp) failed: Connection refused
答案2
原来是个大问题? Nginx 已将worker_processes 设置为0。我在nginx.conf 的顶部添加了一行设置auto
,一切都很好!
感谢大家的时间和耐心。
答案3
我通过在配置文件/etc/nginx/nginx.conf中添加一个websocket解决了这个问题,你可以在中看到反向代理的整个配置文件https://help.teradici.com/s/article/1050
神奇的部分是添加:
upstream websocket {
server <DESTINATION_IP>:<DEST_PORT>;
}
