Nginx 反向代理
最近web服务器因需要增加安全防护开通了web防火墙。但是防火墙支持80,8080（也有跟多端口的，但是它贵啊，它贵啊），没办法，只能修改结构了。
最初的服务架构：1对1 服务。及时增加服务，tomcat也不用重启，因为只用它运行了web前端。

第一步：准备nginx 我这里服务器是server2019
下载win nginx 最新版本 nginx-1.20.2 安装到一个可靠目录
进入nginx 的目录html目录下。分别创建zhangsan、lisi 文件夹。每个文件夹下方一个index网页。
index网页内容如下：
注意两个网页不同地方就在请求的域名后跟的路由不同一个是zhangsan、一个是lisi
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="Generator" content="EditPlus®">
<meta name="Author" content="">
<meta name="Keywords" content="">
<meta name="Description" content="">

<script src="http://code.jquery.com/jquery-latest.js"></script>
</head>
<body>
ceshi_1
</body>
<script type="text/javascript">
let serverUrl=location.origin;
$("body").append(serverUrl);
$.get(location.origin+"/lisi/v1/api/led/getAllLedList");
</script>
</html>

<script type="text/javascript">
let serverUrl=location.origin;
$("body").append(serverUrl);
$.get(location.origin+"/zhangsan/v1/api/led/getAllLedList");
</script>
</html>
接下来配置nginx
进入nginx conf 目录下找到 nginx.conf文件，编辑
#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

}

#gzip on;
server {
listen 8888;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;

#location / {
# root html/mine_ceshi1;

}

add_header 'Access-Control-Allow-Origin' $http_origin;

}

}

# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /.ht {
# deny all;
#}
}
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;

# root html;

# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}说明：1. location ^~/zhangsan/v1/ 配置说明张三请求的proxy 端口9001
2. location ^~/lisi/v1/ 配置说明张三请求的proxy 端口12002
至此配置启动完成。
启动nginx 双击ngInx.exe即可
如果需要重新生效配置文件 ngInx -s reload 即可
这个时候分别访问
注意这里为了和现有的80 重复分开我的nginx 用了8888 端口
localhost:8888/zhangsan
localhost:8888/lisi
查看网页数据返回是不是不同了？
哈哈 ，有兴趣的小伙伴试下吧。有问题留言。
