Prepare two Linux, with a second linux host to take a picture by picture link to show the first host;
Because the host 2 via the host to take the picture link 1 so when others are accessible via a link pictures, is occupied by a host memory space, rather than the host memory space occupied 2
A) set to host a server-based company, once the non-company personnel to access the images via the link, will cause the server memory pressure. Therefore, to set up a non-company personnel can not access the link
Solution, do host a security chain function can effectively prevent non-company personnel to access pictures. To cause memory pressure ------- "This host 2 will even have access to see the picture image link
The first Ip address: 192.168.200.115
A second address value ip: 192.168.200.105
Not only add letters ago Pictures:
Changes index.html Add a picture:
[root@localhost ~]# cd /usr/local/nginx/html/
[root@localhost html]# ls
50x.html index.html
[root@localhost html]# vim index.html
Add image link under paragraph p <img src = "http://192.168.200.115/linux.jpg" / >
After adding pictures
Add the following in order of 1 server host
[root@localhost ~]# vim /usr/local/nginx/html/error.txt

================================================================================
Real machine changes to the hosts file: hosts file is located (C disk windows, system32, drivers, etc in)
File content changes are as follows:
192.168.200.115 www.source.com
192.168.200.105 www.steal.com
=================================================================================
A host, the host browser to access the two comparison
www.source.com need to force a refresh the page press (shift + fn + f5)
www.sttal.com need to force a refresh the page press (shift + fn + f5)
