原始的 nginx 配置

upstream service_test {

     server 127.0.0.1:8080;

}

server

{

  listen    80;

  server_name test.com;

  index index.html index.php;

  root /tmp/test.com;

  error_page 404 http://test.com/404.html;

  error_page 502 http://test.com/502.html;

  error_page 500 http://test.com/500.html;

  location ~* \.(gif|jpg|jpeg|png|css|js|ico|txt|svg|woff|ttf|eot)$

  {

    rewrite ^(.*)$ /static$1 break;

    root /tmp/test.com; #

    expires 1d;

  }

  location ~* \.(html|htm)$

  {

    rewrite ^(.*)$ /static$1 break;

    roo /tmp/test.com; #

    expires 900s;

  }

  location / {

     proxy_pass http://service_test;

     include /opt/conf/nginx/proxy.conf;

  }

修改后的 Nginx 配置

upstream service_test {

     server 127.0.0.1:8080;

}

server

{

  listen    80;

  server_name test.com;

  index index.html index.php;

  root /tmp/test.com;

  error_page 404 http://test.com/404.html;

  error_page 502 http://test.com/502.html;

  error_page 500 http://test.com/500.html;

  location ~* \.(gif|jpg|jpeg|png|css|js|ico|txt|svg|woff|ttf|eot)$

  {

    rewrite ^(.*)$ /static$1 break;

   root /tmp/test.com; #

    expires 1d;

  }

  location ~* \.(html|htm)$

  {

    rewrite ^(.*)$ /static$1 break;

    roo /tmp/test.com; #

    expires 900s;

  }

  set $flag 0;

  if ($request_uri ~* "^/fuck/\w+\.html$") {

      set $flag "${flag}1";

  }

  if ($remote_addr !~* "192.168.0.50|192.168.0.51|192.168.0.56") {

    set $flag "${flag}2";

  }

  if ($flag = "012") {

    rewrite ^ /index.html permanent;

  }

  location / {

     proxy_pass http://service_test;

     include /opt/conf/nginx/proxy.conf;

  }

在实现需求的过程中出现的问题

把 if 指令 和 proxy_pass 都放在 location 下面的话,if 指令里面的内容不会执行,只会执行 proxy_pass。

location / {   if ($remote_addr !~* "192.168.0.50|192.168.0.51|192.168.0.56") {      rewrite ^ /index.html permanent;   }   proxy_pass http://service_test;   include /opt/conf/nginx/proxy.conf;}

if 指令下面使用 proxy_pass 指令问题

像下面这样使用会报错,错误的方式:

   if ($remote_addr ~* "192.168.0.50|192.168.0.51|192.168.0.56") {

     proxy_pass http://test.com/fuck;

   }

正确的方式:

   if ($remote_addr ~* "192.168.0.50|192.168.0.51|192.168.0.56") {

     proxy_pass http://test.com$request_uri;

   }

或是

   if ($remote_addr ~* "192.168.0.50|192.168.0.51|192.168.0.56") {

     proxy_pass http://test.com;

   }

如果你是直接另外启动一个 location 的话,比如启动如下 location :

 location /fund {     if ($remote_addr !~* "192.168.0.50|192.168.0.51|192.168.0.56") {

       rewrite ^ /index.html permanent;

    }  }

这样的方式也是不支持的,当用 IP 192.168.0.50 访问的时候,没有达到我们的业务需求,会报错 400
