我目前正在尝试使用以下教程在 Centos 7 上安装 Apachehttps://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-centos-7。
当我输入以下命令systemctl start httpd.service启动 Apache 时，出现以下错误：Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.
有人能帮助我了解这里出了什么问题吗？另外请记住，在服务器和 Linux 方面我完全是个菜鸟，因为我以前从未使用过它们。
我还输入了以下命令systemctl status httpd.service并得到以下返回：
httpd.service - The Apache HTTP Server

如果这些有帮助的话。
答案1
地址已在使用中：AH00072：make_sock：无法绑定到地址 [::]:80 / 0.0.0.0:80
另一个进程已在监听默认 HTTP 端口 80，因此 Apache 无法使用它，因此无法启动。要调查以下命令可能有用：
sudo netstat -tnlp | grep :80
或者
ss -tnlp | grep :80
