{
    expires 7d;
    valid_referers none blocked server_names  *.test.com ;

编辑虚拟配置文件允许ip和不允许ip访问这是针对目录的

[[email protected] ~]# vim /usr/local/nginx/conf/vhost/test.com.conf
location /admin/
{
    allow 192.168.133.1;
    allow 127.0.0.1;
    deny all;
}

编辑虚拟配置文件这是针对正则的

location ~ .*(abc|image)/.*.php$
{
        deny all;
}

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[[email protected] ~]# /usr/local/nginx/sbin/nginx -s reload

[[email protected] ~]# mkdir /data/wwwroot/test.com/upload     ##做一个模拟创建一个upload目录
[[email protected] ~]# echo "111" > /data/wwwroot/test.com/upload/1.php     ##在upload里面创建个PHP文件
[[email protected] ~]# curl -x127.0.0.1:80 test.com/upload/1.php     ##测试访问upload/1.php是被拒绝的
<html>
<head><title>403 Forbidden</title></head>
<body bgcolor="white">
<center><h1>403 Forbidden</h1></center>
<hr><center>nginx/1.14.0</center>
</body>
</html>

根据user_agent限制配置虚拟文件

[[email protected] ~]# vim /usr/local/nginx/conf/vhost/test.com.conf

if ($http_user_agent ~ ‘Spider/3.0|YoudaoBot|Tomato‘)
{
      return 403;
}

Nginx解析php相关配置

技术分享图片

因为现在配置虚拟文件里还不能解析php所以配置

[[email protected] ~]# vim /usr/local/nginx/conf/vhost/test.com.conf

需要添加的内容

location ~ .php$
    {
        include fastcgi_params;
        fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /data/wwwroot/test.com$fastcgi_script_name;
    }

做个PHP

[[email protected] ~]# vim /data/wwwroot/test.com/3.php
<?php                     ##添加到3.php里边
phpinfo();

做一下测试

[[email protected] ~]# curl -x127.0.0.1:80 test.com/3.php     ##不能解析直接显示源码
<?php
phpinfo();

之前做了配置没有重新加载所以上边的解析没有成功下面加载

[[email protected] ~]# /usr/local/nginx/sbin/nginx -t
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[[email protected] ~]# /usr/local/nginx/sbin/nginx -s reload

**加载完成后在做测试可以解析php

写个新的配置文件

[[email protected] ~]# cd /usr/local/nginx/conf/vhost/   ##进入vhost
[[email protected] vhost]# vim proxy.conf            ##编辑添加内容
server              添加这些东西
{
    listen 80;
    server_name ask.apelearn.com;

    location /
    {
        proxy_pass      http://121.201.9.155/;
        proxy_set_header Host   $host;
        proxy_set_header X-Real-IP      $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
