Linux配置Apache服务报错could not bind to address

Linux下配置Apache服务
使用systemctl start httpd.service失败，错误信息如下

12月 03 01:03:18 localhost.localdomain systemd[1]: Starting The Apache HTTP Server...
12月 03 01:03:18 localhost.localdomain httpd[3607]: (99)Cannot assign requested address: AH00072: make_sock: could not bind to address 192.168.3.4:80

怎么回事

你查看一下，是否有其余程序占用了80端口(netstat -lntup | grep 80）
还有，去查系统日志 /var/log/messages 看看更具体的报错信息，看看报错说啥来定位。

我给你配置啊
