遇到这个情况。说明80port被占用。也就是你系统已有了80port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，也就是还有一个容器而已

比方我机器上就有nginx占用。那么 ./usr/local/nginx/nginx -s stop

然后再起  service httpd start

就可以

当然还有一种办法就是改动httpd默认port80,但不推荐
