🌅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.

# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
### Default server configuration
#
server {listen 80 default_server;listen [::]:80 default_server;# SSL configuration## listen 443 ssl default_server;# listen [::]:443 ssl default_server;## Note: You should disable gzip for SSL traffic.# See: https://bugs.debian.org/773332## Read up on ssl_ciphers to ensure a secure configuration.# See: https://bugs.debian.org/765782## Self signed certs generated by the ssl-cert package# Don't use them in a production server!## include snippets/snakeoil.conf;root /var/www/html;# Add index.php to the list if you are using PHPindex index.html index.htm index.nginx-debian.html;server_name _;location / {# First attempt to serve request as file, then# as directory, then fall back to displaying a 404.try_files $uri $uri/ =404;}# pass PHP scripts to FastCGI server##location ~ \.php$ {# include snippets/fastcgi-php.conf;## # With php-fpm (or other unix sockets):# fastcgi_pass unix:/run/php/php7.4-fpm.sock;# # With php-cgi (or other tcp sockets):# fastcgi_pass 127.0.0.1:9000;#}# deny access to .htaccess files, if Apache's document root# concurs with nginx's one##location ~ /\.ht {# deny all;#}
}# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
# listen 80;
# listen [::]:80;
#
# server_name example.com;
#
# root /var/www/example.com;
# index index.html;
#
# location / {
# try_files $uri $uri/ =404;
# }
#}
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。
