80端口未被占用，Apache却无法启动。

Question

wamp一直是橙色的；
其中Apache点启动没有反应；
1.点测试80端口显示Your port 80 is not actually used.；
2.电脑里也没有Internet信息服务(iis)器；
3.服务里面尝试启动wampapache；提示windows无法启动wampapache服务；

网上实在找不到解决的方法了，求助各位大神

Answer 1

打开apache目录，查看目录下的log.txt或者error.log，里面会有报错信息

Answer 2

1、win + R 输入cmd确定
2、输入netstat -ano|findstr 80回车
查看是否有80端口项，如果有，记录最后面一列上的数字
3、输入tasklist |findstr 上面记录的数字
然后就可以看到是哪个程序占用的80端口

Answer 3

输入netstat -ano|findstr 80回车

查看Apache错误日志后面几行：
