启动apache时的问题

[root@samba ~]# /usr/local/apache/bin/apachectl start
(9Address already in use: make_sock: could not bind to address [::]:80
(9Address 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

为何呢？
在http.conf里已经填写了相应的选项啊！！！

Address already in use

是不是已有系统默认的，或者其它东西占用了。

sockstat看看
