1. 反向代理

参考：https://www.vpser.net/manage/linux-vps-nginx-reverse-proxy.html
介绍：
反向代理简单来说就是访问 a.com，而显示的是 b.com 的内容。
配置文件：

server
{
    listen          80;
    server_name     a.com;

    location / {
        proxy_pass              http://b.com/;
        proxy_redirect          off;
        proxy_set_header        X-Real-IP       $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

1. typecho 伪静态

介绍：
伪静态通俗来说就是去掉网址中的 index.php
配置规则：

if (!-e $request_filename) {
rewrite ^(.*)$ /index.php$1 last;
}

附：官方文档中的安装方法
链接：http://nginx.org/en/linux_packages.html

RHEL/CentOS

Install the prerequisites:

sudo yum install yum-utils

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

[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

[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

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

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

To install nginx, run the following command:

sudo yum install nginx

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