🌅1. 问题描述

在启动nginx服务的时候显示内容如下:

<code>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:

<code>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:

<code>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. 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 PHP

index 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。
