Httpd:could not reliably determine the server ' s fully qualified domain name (RPM)

Ttpd:could not reliably determine the server ' s fully qualified domain name, using 127.0.0.1 for ServerName

The workaround is simple:

#vim/web/apache/conf/httpd.conf (here/web/apahce is the directory where I installed Apache, you should install it by default/usr/local/apache2/icons)

Find #servername www.example.com:80 to remove, and then restart Apache can be all right.

Phenomenon:

bogon:~/webserver/httpd-2.0.59 #/usr/local/apache2/bin/apachectl Start
Httpd:could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
HTTPD (PID 20183) already running

This question should not be set in/etc/httpd/conf/httpd.conf ServerName

Vi/usr/local/apache2/conf/httpd.conf

The simplest, modified httpd.conf file, adds:
ServerName www.example.com:80
I change to:

ServerName www.example.com:80

It's normal to start again!
