不小心在 nginx 上安装了 apache答案

【问题标题】：Accidentally installed apache over nginx不小心在 nginx 上安装了 apache
【发布时间】：2021-03-26 04:26:28
【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，我尝试在我的服务器上安装 mautic，我按照复制和粘贴教程进行操作，但直到最后我才注意到该教程是针对 Apache 的。我的所有网站立即获得 HTTP 500 错误状态。因此，我卸载了 Apache 并再次启动了 nginx，然后一切恢复正常。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 再次安装。但是后来我得到了这个错误

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

 nginx: [emerg] unknown directive "more_set_headers" in /etc/nginx/nginx.conf:41

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

【解决方案1】：

nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)

表示已有进程使用端口 80，该端口是 Web 服务器用于提供 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，如果它已停止，请检查哪个服务正在侦听端口 80：

sudo netstat -tupan | grep -i list

您将显示类似于此的输出：

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

这意味着 pid 为 12431 的进程正在侦听端口 80 和 443。该进程称为 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' 是您要查找的进程。

一旦您发现阻止 nginx 启动的进程，您应该使用 kill 命令或 systemctl（或您正在使用的任何东西）终止它。

释放端口后，您可以尝试再次启动 nginx。
