我在使用 Apache 时遇到问题。我刚刚安装了 Centos，想要创建一个自己的网络服务器。我正在遵循“centos 7.2 的完美服务器“并在我的机器上遇到了这个错误
[root@server01 /]# sudo systemctl start httpd
Job for httpd.service failed because the control process exited with error code. See "systemctl status httpd.service" and "journalctl -xe" for details.

这是我的虚拟主机文件的示例
有人可以帮我解决这个问题吗？
运行sudo netstat -nap | grep :80回报

现在再次运行此命令systemctl status httpd.service我仍然遇到相同的错误
[root@server01 /]# systemctl status httpd.service

问题仍然阻止我启动
运行命令nmap 192.168.0.1返回
Starting Nmap 6.40 ( http://nmap.org ) at 2016-11-06 15:52 PST

为什么端口 80 或端口 443 根本不显示？
答案1
您已经在端口 80 上运行某些内容。此命令将为您识别它
sudo netstat -nap | grep ':80 .*LISTEN'
答案2
我会说使用 nmap 来查看正在运行哪些服务以及在哪个端口上运行。 nmap 结果看起来像这样......
$ nmap 192.168.50.25
...
PORT STATE SERVICE
22/tcp open ssh
25/tcp open smtp
80/tcp open http <~ make sure service is http
443/tcp open https
如果除 http 之外的其他内容正在使用端口 80，您可以更改 apache 配置并将其指向不同的端口，或者将使用端口 80 的服务更改为其他端口。这是安装 nmap 的指南
答案3
首先你应该使用命令：
netstat -natup |grep 80
你应该让我们知道哪个服务正在运行，如果端口80被其他服务使用，你必须杀死它。
如果这样还不能解决问题，可以检查httpd.conf的权限，检查是否有以下命令：
listen [::]:80
因为我们可以知道您的系统日志中的错误
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:80
有时这个问题是由 ipv6 引起的，所以你应该在你的conf中添加该命令
listen [::]:80 ipv6only=off default_server;
然后重启httpd服务就可以了
