问题描述
我目前使用 WordOps (wordops.net) 运行服务器。使用 WordOps，您可以自动安装 Nginx。
今天早上我试图在我的服务器上安装 mautic，我按照复制和粘贴教程进行了操作，但直到最后我才注意到该教程是针对 Apache 的。我的所有站点立即都获得了 HTTP 500 错误状态。于是，我卸载了 Apache 并再次启动了 Nginx，然后一切都恢复了正常。但是，我决定在它之后使用命令“apt-get upgrade -y”，然后 Nginx 停止工作。因此，我尝试完全卸载 Nginx 并使用 WordOps 重新安装。但后来我得到这个错误

当我尝试使用 apt-get install Nginx-full 安装 Nginx 时出现此错误

当我使用 apt-get install Nginx-extras 时出现此错误

我有点绝望哈哈 任何帮助将不胜感激
解决方法
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)
表示有一个进程已经在使用端口 80，这是 Web 服务器用来提供 http 内容的端口。该进程可能是 apache、nginx 或您正在运行的任何其他服务。
检查 nginx/apache 的状态，如果它停止检查哪个服务正在监听端口 80：
sudo netstat -tupan | grep -i list
您将显示与此类似的输出：
tcp6 0 0 :::22 :::* LISTEN 574/sshd
tcp6 0 0 :::443 :::* LISTEN 12431/apache2
tcp6 0 0 :::111 :::* LISTEN 1/init
tcp6 0 0 :::80 :::* LISTEN 12431/apache2
表示pid为12431的进程正在监听80和443端口。这个进程叫做apache2。 如果没有显示名字，可以用ps查找：
ps aux | grep 12431
输出将如下所示：
root 12431 0.0 2.3 238408 22796 ? Ss Mar10 10:04 /usr/sbin/apache2 -k start
这意味着进程 '/usr/sbin/apache2' 是您正在寻找的进程。
一旦你发现是什么进程阻止了 nginx 启动，你应该用 kill 命令或 systemctl（或你正在使用的任何东西）终止它。
端口被释放后，您可以再次尝试启动 nginx。
