Nginx configure proxy for Internet access

1 Nginx introduction Nginx is similar to Apache & amp; 20284;. in the past, the lab network was unrestricted, while many foreign websites in the dormitory could not be opened, and both the dormitory and lab were on the campus network, this allows you to browse the web page in the dormitory through the lab network. nginx introduction Nginx is similar to Apache. in the past, the lab network was unrestricted, while many foreign websites in the dormitory could not be opened, and both the dormitory and lab were on the campus network, this allows you to browse the web page through the lab network in the dormitory through the proxy. in this way, I forget whether it is a forward proxy or a reverse proxy ????

2. the following is the modified configuration file.

3. the current status of the main changes: only one machine can access the Internet (web), and other machines cannot
Method: a proxy web server can be used for Internet access, and other machines can connect to it. Nginx

The Nginx configuration is as follows:

Server {
Resolver x. x;
Listen 82;
Location /{
Proxy_pass http: // $ http_host $ request_uri ;}}
Note: 1. there cannot be hostname2. there must be a resolver, that is, dns, that is, the above x. x. x. x. replace it with your DNS server ip address. $ http_host and $ request_uri are nginx system variables. do not replace them. if they are the same, they are OK.
View dns methods cat/etc/resolv. conf
4. the proxy is used in linux. I remember using a plug-in the chrome browser at that time. just fill in the proxy server IP address and port.
1. export http_proxy = http: // yourproxyaddress: proxyport2. gedit ~ /. Bashrc export http_proxy = http: // yourproxyaddress: proxyportyourproxyaddress is the ip address of your Nginx server. proxyport is the 82 configured above and can be modified as needed.

2. Master_process off;
3. Daemon off;
