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

# 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. These applications will be made
# available underneath a path with that package name, such as /drupal8.

#
# root /var/www/example.com;

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。
