httpd: apr_sockaddr_info_get() failed for www
httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
Syntax OK
解决办法1
vim /usr/local/apache2/conf/httpd.conf
ServerName www.example.com:80 ServerName localhost:80
解决办法2
vim /etc/hosts
# 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 127.0.0.1 localhost.localdomain localhost www ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
把原来的注释掉，加一行新的，最后的www是主机名
