Note: conf/htpasswdFileThe content can be generated using the htpasswd tool provided by apache.

3) view Nginx running status

Enter the http: // 192.168.8.1/NginxStatus/address, and enter the verification account password. The following content is displayed:

Active connections: 328

Server accepts handled requests

9309 8982 28890

Reading: 1 Writing: 3 Waiting: 324

The first line indicates the number of currently active connections.

The third number in the third row indicates the total number of requests received from Nginx running to the current time. If the number reaches the upper limit, the upper limit must be increased.

The fourth line is the Nginx queue status.

Proxy dns resolution

Server {

Listen 8080;

Location /{

Proxy_pass http: // $ http_host $ request_uri;

Access_log off;

}

}

In addition, you also need to use resolver to specify the DNS server in the http field, otherwise the "nginx 502 bad gateway" error will occur. I use the DNS service provided by Google:

Resolver 8.8.8.8;

After modification, restart the nginx Server:

Nginx-s reload

Finally, modify the browser proxy settings and access www.ip.cn to see that the IP address has changed.

------------------------------------------------------------------------------

Add several lines in nginx. conf to support several websites:

Server {

Listen 80;

Server_name www.3js.com.cn;

Location /{

Proxy_pass http://block.3js.com.cn: 81;

}

}

Example:

Server {listen 80; server_name www.3js.com.cn; location/{proxy_passhttp: // block.3js.com.cn: 81 ;}}

Server {listen 80; server_name www1.3js.com.cn; location/{proxy_passhttp: // block.3js.com.cn: 82 ;}}

Server {listen 80; server_name www2.3js.com.cn; location/{proxy_passhttp: // block.3js.com.cn: 83 ;}}
