Ubuntu lamp solves the coexistence problem of 2 websites

Little brother Contact Lamp not long time, many things are their own 1.1 point groping, a lot of problems hope to make friends
The following 2 scenarios certainly have security issues, and I hope you will criticize that the following scenarios are for informational purposes only.

Programme 1:

Different IP addresses with different sites
Bind the 2nd IP to the NIC:
The two network cards are named Eth0 and eth1 respectively. Where the eth0 is connected to the extranet. IP for 202.118.21http://www.aliyun.com/zixun/aggregation/37104.html ">0.121
This requires adding a virtual NIC eth0:0 and binding IP202.118.210.124
Ludaxing@linux:/$sudo vi/etc/network/interfaces

Add Auto eth0:0
Iface eth0:0 inet Static
Address 202.118.210.124
Netmask 255.255.255.128
Receptacle 202.118.210.0
Broadcast 202.118.210.127
Gateway 202.118.210.126

Modify Apache2 Virtual host settings
ludaxing@linux:/$ sudo vi/etc/apache2/ports.conf
Modify the contents of the inside
Listen 80
Namevirtualhost 202.118.210.121:80
Namevirtualhost 202.118.210.124:80

<virtualhost 202.118.210.121:80>
ServerName www.example.com
Documentroot/var/www/server1
</VirtualHost>

<virtualhost 202.118.210.124:80>
ServerName www.example2.com
Documentroot/var/www/server2
</VirtualHost>

Restart receptacle and Apache. Make configuration effective.

Programme 2:

Through the Apache virtual directory function to achieve
Add the following to the virtual machine settings
Alias/server2 "/var/www/server2"
<directory "/var/www/icons" >
Options Indexes MultiViews
AllowOverride None
Order Allow,deny
Allow from all
</Directory>

Content attributes

1.Options: Defining directory Attributes
Indexes allows directory browsing (browse directory files)
MultiViews multiple views allowing content negotiation (full file name)
All features except MultiView (if no options, default to All)
EXECCGI allows CGI scripts to be executed
Recursively allows server-side include functionality
IncludesNOEXEC allows server-side include functionality, but does not support CGI

2. Set the directive type in the. htaccess file.
Alllowoverride None (set directly in the configuration file without using Htacces)

3. Processing order of access rights
Order Allow,deny: Disable all client access by default
Order Deny,allow: All clients are allowed access by default
