CentOS 7.6 安装Nginx及关闭nginx默认配置

article/2025/9/27 17:22:43

我使用的服务器是阿里云的服务器。

配置好后，直接用IP访问网站没有问题，但是使用域名解析访问一直是welcome to nginx！页面，是因为其使用了默认配置，将下文所给配置中第19行注释掉即可！

首先更新一下yum

yum update

1. 安装Nginx

Nginx官网
官网CentOS系统上安装方法

1.1 安装说明

Installation instructions
Before you install nginx for the first time on a new machine, you need to set up the nginx packages repository. Afterward, you can install and update nginx from the repository.

在第一次在新机器上安装nginx之前，需要设置nginx包存储库。之后，您可以从存储库安装和更新nginx。

1.2 安装必备组件

sudo yum install yum-utils

1.3 设置存储库

To set up the yum repository, create the file named with the following contents:
/etc/yum.repos.d/nginx.repo

在/etc/yum.repos.d目录下创建nginx.repo文件，将下面内容写入到该文件中；

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

By default, the repository for stable nginx packages is used. If you would like to use mainline nginx packages, run the following command:

注：默认使用稳定的nginx包存储库，如需修改使用主线存储库，请执行以下命令：

sudo yum-config-manager --enable nginx-mainline

1.4 安装nginx

To install nginx, run the following command:

sudo yum install nginx

When prompted to accept the GPG key, verify that the fingerprint matches , and if so, accept it. 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62

执行以下命令，开始安装nginx：

sudo yum install nginx

当提示接受GPG密钥时，请验证是否与573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62匹配，如果匹配，请接受。

2. 配置Nginx

# 查看Nginx配置信息位置及校验nginx配置信息是否存在错误
nginx -t

Nginx 配置文件nginx.conf中文详解
我的配置：
/etc/nginx中输入vim nginx.conf

user  nginx;
worker_processes  2;
error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;
events {worker_connections  1024;
}
http {include       /etc/nginx/mime.types;default_type  application/octet-stream;log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log  /var/log/nginx/access.log  main;sendfile        on;#tcp_nopush     on;keepalive_timeout  65;#gzip  on;#include /etc/nginx/conf.d/*.conf;server{listen 80;server_name 主机IP地址;location /{root /www;index index.html;}}
}
