使用官方源安装nginx

基于服务器：CentOS
1、配置官方源

vi /etc/yum.repos.d/nginx.repo

输入如下内容（参考https://nginx.org/en/linux_packages.html）：

[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

2、清除epel源的影响（如果存在epel源则注释掉，没有请忽略）

mv /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel.repo.bak

3、yum重新生成缓存

yum clean all
yum makecache

4、yum安装nginx

yum install -y nginx

5、启动nginx

systemctl start nginx

6、查按nginx相关文件

[root@localhost ~]# rpm -qc nginx  #查询nginx配置文件
/etc/logrotate.d/nginx
/etc/nginx/conf.d/default.conf
/etc/nginx/fastcgi_params
/etc/nginx/mime.types
/etc/nginx/nginx.conf
/etc/nginx/scgi_params
/etc/nginx/uwsgi_params

7、访问测试，输出”Welcome to nginx!“则说明部署OK

[root@localhost ~]# curl http://127.0.0.1
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
    }
</style>
</head>
<body>
<h1>Welcome to nginx!</h1>
