<VirtualHost *:8001># The ServerName directive sets the request scheme, hostname and port that# the server uses to identify itself. This is used when creating# redirection URLs. In the context of virtual hosts, the ServerName# specifies what hostname must appear in the request's Host: header to# match this virtual host. For the default virtual host (this file) this# value is not decisive as it is used as a last resort host regardless.# However, you must set it for any further virtual host explicitly.#ServerName www.example.comServerAdmin webmaster@localhostDocumentRoot /var/www/html# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,# error, crit, alert, emerg.# It is also possible to configure the loglevel for particular# modules, e.g.#LogLevel info ssl:warnErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined# For most configuration files from conf-available/, which are# enabled or disabled at a global level, it is possible to# include a line for only one particular virtual host.
