ubuntu configure php development environment (apache php)

Configure apache2 multi-site

1. In sites-available Create a site configuration file

sudo cp 000-default.conf meili.com.conf
code meili.com.conf

Edit the content inside

<VirtualHost *:80>
    ServerName meili.com
    # ServerAdmin webmaster@localhost
    DocumentRoot /var/www/meili.com
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

2. Copy the newly created site configuration file in sites-available to the sites-enabled directory (soft links are useless, copying is the safest)

sudo cp meili.com.conf /etc/apache2/sites-enabled/meili.com.conf

3. Modify the hosts file and add a virtual domain name

127.0.0.1   meili.com

4. Restart the Apache server

sudo service apache2 restart
