遇到这个情况，说明80端口被占用，也就是你系统已有了80端口暂用，怎么办了

先检查下：

[root@luozhonghua sbin]# netstat -lnp|grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 5619/nginx
unix 2 [ ACC ] STREAM LISTENING 12380 1759/abrtd /var/run/ab rt/abrt.socket
unix 2 [ ACC ] STREAM LISTENING 16831 2143/nautilus /tmp/orbit- root/linc-85f-0-3e753e8283a80

方法是，关闭被占用的程序，一般来说，也就是另一个容器而已

比如我机器上就有nginx占用，那么 ./usr/local/nginx/nginx -s stop

然后再起 service httpd start

即可

当然另一种办法就是修改httpd默认端口80,但不推荐
