Centos configures the virtual host virtualhost, allowing the server to support multiple websites and multiple domain names

For Apache, you only need to modify the apache configuration file.

For Apache, you only need to modify the apache configuration file/etc/httpd/conf/httpd. conf.

There is an example file in it. you only need to configure it.

#

# ServerAdmin webmaster@dummy-host.example.com

# DocumentRoot/www/docs/dummy-host.example.com

# ServerName dummy-host.example.com

# ErrorLog logs/dummy-host.example.com-error_log

# CustomLog logs/dummy-host.example.com-access_log common

#

You can add at the bottom of httpd. conf by referring to my configuration:

NameVirtualHost *: 80

ServerAdmin admin@example.com

DocumentRoot/var/www/html

ServerName www.phpddt.com

# ErrorLog/var/log/httpd/phpddt/error_log

# Note: Here I set the daily production log

ErrorLog "| rotatelogs/var/log/httpd/phpddt/error_log % Y _ % m _ % d. log 86400 480"

# CustomLog/var/log/httpd/phpddt/access_log common

CustomLog "| rotatelogs/var/log/httpd/phpddt/access_log % Y _ % m _ % d. log 86400 480" common

ServerAdmin admin@example.com

DocumentRoot/var/www/html/blog

ServerName blog.phpddt.com

ErrorLog/var/log/httpd/blog/error_log

CustomLog/var/log/httpd/blog/access_log common

As shown above, I have configured two virtual hosts with the domain names www.phpddt.com blog.phpddt.com respectively.
Note: service httpd restart takes effect only after apache is restarted)

If the reader does not understand anything, I strongly recommend other related articles:
