Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80

ubuntu上安装Apache2时出现错误

Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80  

端口被占用形成

在root权限下键入命令：

# netstat -lnp | grep 80

从图中能够看出nginx占用了进程

键入命令

#pkill -9 nginx

杀死nginx的全部进程

再次启动Apache成功
