Apache does not start: Unable to open logs error is why

Apache does not start: unable to open logs

Reason Record:

1:80 port is accounted for, I encountered the situation is the QQ music 80 ports occupy, turn off the corresponding program on OK

2: Problems with configuration parameters I allowoverride the value behind the allow so it goes wrong and should be with all

3.Apache default 80 port is occupied to report this error

Use Netstat-ano to view the PID of the application of listening 80 in the local address, to find the corresponding process in Task Manager, and close this process.
The process I found here is actually a process called pear.exe, and I don't know if it listens to port 80. Why, it looks a little old.

There is said that the computer does not configure the domain name, configuration parameters have a servername xxx.xxx.xxx:80, modified to IP (this machine with 127.0.0.1), start successfully.
