Apache virtual host
Why do you need to use virtual hosts:
First of all, it's a host, and it has an operating system.
We also need IP addresses, but for those small sites, it is extremely wasteful. So we expect to be able to virtualize multiple hosts on one host and be able to serve many different sites
# #
Apache:
Central host: section2
Virtual host: 3
The same IP hostname is different
Www.magedu.com
Www.a.org
Definition of virtual host: first cancel the central host, that is, comment DocumentRoot
1. Writing method based on IP,Host
HOST
IP1:80
IP2:80
2. Based on port:
HOST
IP:80
IP:8080
3. Based on domain name:
*: 80
ServerName cannot be the same
# #
Specific implementation method: based on IP authentication
1. Cancel the central host # DocumentRoot
2 、 cd / etc/httpd/conf.d;;vim virtual.conf
3 、
ServerName hello.magedu.com
DocumentRoot "/ www/magedu.com"
ServerName www.a.org
DocumentRoot "/ www/a.org"
4. Httpd-t checks whether there are any grammar errors.
5. Mkdir-pv / www/ {magedu.com,a.org} create a directory
6. Cd magedu.com;; vim index.html
7. Editing
MageEdu
Magedu.com
8. Ip addr add 192.168.9.248 dev eth0 add another IP address to the host
9. Ip addr show shows
# #
Port-based authentication:
1. Add and edit the configuration file under conf.d; you will find that you already have 247 IP but the port is different.
ServerName www.b.net
DocumentRoot "/ WWW/b.net"
2. Edit the main configuration file / etc/httpd/conf/httpd.conf
Listen 80
Listen 8080
3. Edit / www/b.net/index.html
4. Restart it.
#
Name-based virtual host
0 、 vim / etc/httpd/conf/httpd.conf
1. NameVirtualHost *: 80 uncomment means all IP on port 80
3 、 vim / etc/httpd/conf/virtual
4. Add NameVirtualHost 192.168.9.248 to the first line
ServerName www.a.org
DocumentRoot "/ www/a.org"
ServerName www.b.gov
DocumentRoot "/ www/b.gov"
# 333333333
You can also customize the location and format of the specified log.
ServerName www.b.gov
DocumentRoot "/ www/b.gov"
CustomLog/var/httpd/magedu.com/access_log combined
As long as you have permission, this directory will be created automatically after restart.
# 33
Ask a.org to deny access to the address 192.168.9.226
ServerName www.a.org
DocumentRoot "/ www/a.org"
Options none
AllowOverride none
Order deny,allow
Deny from 192.168.9.226
Save httpd-t to check for syntax errors to restart
# # #
A.org needs to enter a user name and password to log in.
ServerName www.a.org
DocumentRoot "/ www/a.org"
CustomLog / var/log/httpd/a.org/access_log combined
Options none
AllowOverride authconfig
AuthType basic
AuthName "Restrict area."
AuthUserFile "/ etc/httpd/.htpasswd"
Required valid-user
Save;; httpd-t check for syntax errors
Htpasswd-c-m / etc/httpd/.htpasswd tom add tom user
Add more users and remove-c.
Htpasswd-m / etc/httpd/.htpasswd hadoop
# # #
If you access a virtual host that does not exist at all:
ServerName _ default_
DocumentRoot "/ www/default"
Mkdir / www/default
Vim / www/default/index.html
Default
Restart notice that default should be kept on top when editing.
