安装Nginx服务程序，报错80端口被占用

Starting nginx (via systemctl):  Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.

# netstat -ltunp

tcp6       0      0 :::80                   :::*                    LISTEN      812/httpd

# kill 812

# netstat -ltunp

已经杀掉占用80端口进程
