What is a virtual host:

1: Domain-based

2: IP-based

3: Port-based

=======================================================

Gca

Domain Name site

www.a.org /var/html/a/

www.b.com /var/html/b/

www.c.cn/var/html/c/

To edit a configuration file, configure the virtual host:

# Vim/application/apache/conf/extra/httpd-vhost

<virtualhost *:80>

ServerAdmin [email protected]

DocumentRoot "/var/html/a"

ServerName www.a.org

Serveralias a.org

Errorlog "Logs/www-error_log"

Customlog "Logs/www-access_log" common

</VirtualHost>

<virtualhost *:80>

ServerAdmin [email protected]

DocumentRoot "/var/html/b"

ServerName www.b.org

Serveralias b.org

Errorlog "Logs/www-error_log"

Customlog "Logs/www-access_log" common

</VirtualHost>

<virtualhost *:80>

ServerAdmin [email protected]

DocumentRoot "/VAR/HTML/C"

ServerName www.c.org

Serveralias c.org

Errorlog "Logs/www-error_log"

Customlog "Logs/www-access_log" common

</VirtualHost>

three hosts configured above, Access # Curl www.a.org wait for three pages to do the test

# vim/application/apache/conf/httpd.conf

Include conf/extra/httpd-vhosts.conf-Open (commented out by default)

Include conf/extra/httpd-mpm.conf

Edit Master configuration Add a container

# vim/application/apache/conf/httpd.conf

<directory "/var/html" >

Options FollowSymLinks

AllowOverride None

Order Allow,deny

</Directory>

Check syntax:

#/application/apache/bin/apachectl-t

Smooth restart, equivalent to reload:

#/application/apache/bin/apachect Graceful
