(98)Address already in use: make_sock: could not bind to address 80 [resolved] (2012-10-11 09:04)

以前遇到一个问题：

sudo /etc/init.d/apache2 start
 * Starting web server apache2                                                                                                      
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

其实就是80端口被占用的原因，解决办法如下：

sudo fuser -k -n tcp 80

sudo /etc/init.d/apache2 start
