1. Nginx簡介
Nginx是和Apache相似的, 以前實驗室的網絡是不受限制的, 而宿捨的網絡很多國外網站都打不開, 宿捨和實驗室都處於校園網, 這個就可以通過代理在宿捨通過實驗室網絡浏覽網頁. 這樣利用Nginx忘了算是正向代理還是反向代理了????
2. 下面是修改了的配置文件
# /etc/nginx/nginx.conf

# This is the main Nginx configuration file.

3. 主要修改的地方
目前現狀：只有1個機器能上網(web),其他機器不能
方法：能上網的做一個代理web服務器中轉，其他機器連接它即可。采用nginx
Nginx配置如下：
server{
resolver x.x.x.x;
listen 82;
location / {
proxy_pass http://$http_host$request_uri;
}
}
注意項：
1. 不能有hostname
2. 必須有resolver, 即dns，即上面的x.x.x.x，換成你們的DNS服務器ip即可
3 . $http_host和$request_uri是nginx系統變量，不要想著替換他們，保持原樣就OK。
查看dns方法
cat /etc/resolv.conf
4. 代理使用
在linux, 我記得在當時是用的chrome浏覽器的一個插件, 填下代理服務器IP和端口就可以了.
在需要訪問外網的機器上執行以下操作之一即可：
1. export http_proxy=http://yourproxyaddress：proxyport
2. gedit ~/.bashrc
export http_proxy=http://yourproxyaddress：proxyport
yourproxyaddress也就是你的Nginx服務器的ip了，proxyport就是上面配置中的82，可以根據自己的需要修改。
舉例：
-
worker_processes 1;
-
master_process off;
-
daemon off;
-
#pid /var/run/nginx.pid;
-
-
events {
-
worker_connections 768;
-
# multi_accept on;
-
}
-
-
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"';
-
-
access_log /var/log/nginx/access.log;
-
error_log /var/log/nginx/error.log;
-
-
sendfile on;
-
-
server {
-
resolver 10.57.220.2;
-
listen 82;
-
access_log logs/host.access.log main;
-
-
location / {
-
proxy_pass http://$http_host$request_uri;
-
}
-
-
-
}
-
}
