1. 问题描述
在启动nginx服务的时候显示内容如下：
1 | 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：
1 | 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：
1 | 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】：

将里面的代码模块
1 2 3 | server { listen 80 default_server; listen [::]:80 default_server; |
修改成
1 2 3 | 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
1 | sudo systemctl start nginx |
设置Nginx服务自启动：
1 | sudo systemctl enable nginx |
验证Nginx是否运行：
1 | 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。
