🌅1. 问题描述

在启动nginx服务的时候显示内容如下：

sudo systemctl status nginx

问题出现原因：

根据日志显示，Nginx 服务启动失败，主要原因是无法绑定到端口 80。这通常是由于该端口已被

其他进程占用而导致的。

🌊2. 解决方案

要解决此问题，可以执行以下步骤：

确认端口 80 是否被其他进程占用。可以使用以下命令检查：

sudo netstat -tuln | grep :80

该命令会列出正在监听端口 80 的进程。如果有其他进程在使用该端口，显示如下：

打开配置文件：可以将80端口【默认端口】修改为 8080 端口【当然也可以是其他的，不过要记得去防火墙添加规则（即添加端口）】

比如我添加的是 8080 端口，则添加规则如下（红框内容）：

可以使用以下命令打开配置文件：

sudo nano /etc/nginx/sites-available/*

我的配置文件内容如下【版本不同当然配置文件不同】：

### You should look at the following URL's in order to grasp a solid understanding# of Nginx configuration files in order to fully unleash the power of Nginx.# https://www.nginx.com/resources/wiki/start/# https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/# https://wiki.debian.org/Nginx/DirectoryStructure## In most cases, administrators will remove this file from sites-enabled/ and# leave it as reference inside of sites-available where it will continue to be# updated by the nginx packaging team.## This file will automatically load configuration files provided by other# applications, such as Drupal or Wordpress.

将里面的代码模块

server {    listen 80 default_server;    listen [::]:80 default_server;

修改成

server {    listen 8080 default_server;    listen [::]:8080 default_server;

完成修改！【如果其他地方还有 80 的修改成 8080 即可】。

启动Nginx服务

sudo systemctl start nginx

设置Nginx服务自启动：

sudo systemctl enable nginx

验证Nginx是否运行：

sudo systemctl status nginx

如果一切正常，输出应该是“Active: active (running)”或者类似的信息。
