搭建nginx https 反向代理 http tomcat服务实践。

Nginx安装

1、 配置conf，开启443端口，ssl

	其中最为关键的就是 ssl_certificate 和 ssl_certificate_key 这两项配置，其他的按正常配置。proxy_set_header X-Forwarded-Proto https 一定要配置好，不然重定向有问题，会重定向到http。
	
	多注意下面配置
	proxy_set_header Host $host:$server_port;
	proxy_set_header X-Real-IP $remote_addr;
	proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
	proxy_set_header X-Forwarded-Proto https;
	sub_filter_once off;
	sub_filter_types *;

关键配置如下：

server {
      listen       443 ssl;
       server_name  localhost;
	 # 配置证书
       ssl_certificate      server.crt;
       ssl_certificate_key  server.key.unsecure;

       ssl_session_cache    shared:SSL:1m;
       ssl_session_timeout  5m;

       ssl_ciphers  HIGH:!aNULL:!MD5;
       ssl_prefer_server_ciphers  on;
	# 代理配置，
	location /xxx/ {
		proxy_redirect off;
		proxy_set_header Host $host:$server_port;
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
		proxy_set_header X-Forwarded-Proto https;
		client_body_buffer_size 128k;
		proxy_buffer_size  4k;
		proxy_buffers 4 32k;
		proxy_busy_buffers_size 64k;
		proxy_temp_file_write_size 64k;
		proxy_connect_timeout 3;
		proxy_send_timeout 30;
		proxy_read_timeout 30;
		sub_filter_once off;
		sub_filter_types *;
		proxy_pass http://127.0.0.1:8080/xxx/;
	}

   }

Tomcat安装配置

配置支持https 关键配置，修改tomcat server.xml文件。

a： 添加重定向端口redirectPort="443" 和代理端口proxyPort="443"；否则tomcat https请求重定向，代理有问题

    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="443" 
			   proxyPort="443"
			   />

b：host中加value节点RemoteIpValve 属性如下。    否则你在 Tomcat 中的应用在读取 getScheme () 方法以及在 web.xml 中配置的一些安全策略会不起作用。

<Valve className="org.apache.catalina.valves.RemoteIpValve"
                  remoteIpHeader="x-forwarded-for"
                  remoteIpProxiesHeader="x-forwarded-by"
                  protocolHeader="x-forwarded-proto"
            />

个人测试完整配置如下

Nginx

#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;

events {
    worker_connections  1024;
}

http {
 	client_max_body_size 20m;
	client_header_buffer_size 40k;
	open_file_cache max=200 inactive=2h;
	open_file_cache_valid 3h;
	open_file_cache_min_uses 1;
	sendfile on;
	tcp_nopush on;
	tcp_nodelay on;
	keepalive_timeout 60;
	types_hash_max_size 2048;
	server_tokens off;

	# server_names_hash_bucket_size 64;
	# server_name_in_redirect off;

	include mime.types;

    #gzip  on;

	# http配置
    #include nginx_http.conf;


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

	upstream mastery_server {                                                         
		server 127.0.0.1:8081;                                                
		keepalive 2000;
	}
    # HTTPS server
    #
	
	server {
        listen       443 ssl;
        server_name  localhost;

        ssl_certificate      server.crt;
        ssl_certificate_key  server.key.unsecure;

        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;

        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;
		
		location /Mastery/ {
			proxy_redirect off;
			proxy_set_header Host $host:$server_port;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_set_header X-Forwarded-Proto https;
			client_body_buffer_size 128k;
			proxy_buffer_size  4k;
			proxy_buffers 4 32k;
			proxy_busy_buffers_size 64k;
			proxy_temp_file_write_size 64k;
			proxy_connect_timeout 3;
			proxy_send_timeout 30;
			proxy_read_timeout 30;
			sub_filter_once off;
			sub_filter_types *;
			proxy_pass http://127.0.0.1:8080/Mastery/;
		}

    }

}
