我正在尝试创建一个 Web 服务器，但添加虚拟主机配置后，apache 不会重新启动。它有几个错误，但我已经设法修复了其中的大部分。现在我不知道发生了什么，因为journalctl -xn没有给我任何提示。
这是日志：

我不知道我刚刚做了什么，但是测试“httpd -t”命令@garethTheRed告诉我，我想看看它有什么帮助，所以我尝试了“httpd -H”并执行。然后运行“apachectl restart”给了我同样的错误。但这一次看到“journalctl -xn”时发生了变化。 apache 中仍然存在错误，但它已经在测试页 123 上运行。但是 vhost 尚未工作。
这是之后的输出。

有任何想法吗？

答案1
我遇到了类似的问题，事实证明 Apache 不喜欢 VirtualHost 容器中的 ErrorLog 和 CustomLog 行。我将它们注释掉，服务开始没有问题。
我猜这与 httpd.conf 中的权限有关
答案2
对于将来遇到此问题的任何人，不要禁用 SElinux，学习如何使用它。禁用它几乎就像取消枪支上的所有安全装置一样，因为当您尝试射击时扳机将无法工作。
这是解决这个问题的正确方法：
semanage fcontext -a httpd_sys_rw_content_t "/var/www/html(/.*)?"
将允许 apache 权限读取和写入给定目录。
之后，你应该能够restorecon -Rv /var/www/html
这应该可以解决你的问题。
正如@MADforFUNandHappy 发布的
答案3
尝试完全重新启动系统，看起来它正在尝试终止不再存在的进程。
sudo reboot
当系统完全重新启动后，尝试再次运行该命令。
sudo systemctl restart httpd
这应该可以工作，如果不行，请发布“journalctl -xn”输出。
答案4
对我来说，它是通过在 CentOS7 中禁用 selinux 来实现的
要在重新启动后永久禁用，请执行以下操作：
须藤纳米 /etc/selinux/config
SELINUX=允许或禁用
保存文件
须藤 setenforce 0
并检查
