apache安装似乎失败了？

安装了apache2，指定的启动命令是： /usr/local/apache2/bin/apachectl start
我在终端里面以root用户运行是没有问题的，进程里面有4个http相关进程
but在webmin里面的apache里面电机启动apache的时候却提示：启动apache失败 : Apache does not appear to be running :
点第二次的时候提示：
启动apache失败 : Apache does not appear to be running :
httpd (pid 10085) already running

手工在终端启动：
derek@love:/usr/local/apache2/bin> sudo /usr/local/apache2/bin/apachectl start
口令：
derek@love:/usr/local/apache2/bin>
derek@love:/usr/local/apache2/bin>
derek@love:/usr/local/apache2/bin> ps -ef |grep httpd

derek 10194 9708 0 20:41 pts/1 00:00:00 grep httpd
derek@love:/usr/local/apache2/bin>

似乎是没有问题哈？用浏览器打开也没有问题。。不过有点奇怪的就是 即使我关闭apache，浏览器还是能够打开。
