腾讯云（六）80 和 443端口反向代理 tomcat和nginx的配置

一、缘起

由于一个服务器需要部署多个小程序服务端，而小程序必须要使用https协议，需要使用443端口，所以需要将443端口做反向代理。

二、nginx 配置

注意点：
1.ssl_certificate 和 ssl_certificate_key 都是指 nginx/con/ 下的相对位置
1.5 证书和秘钥文件都要放在nginx/con/ 下
2.ssl_certificate_key 后面的空格只能有一个，否则找不到文件
3.一个服务 需要3部分 upstream 、server （80）、server （443），需要增加应用，这3个配置复制一份即可

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
	
	# 服务1
	upstream community {
        server 127.0.0.1:8080;
    }
	
	server {
        listen       80;
        server_name  www.moonknightsoft.com;
		rewrite ^(.*) https://$server_name$1 permanent;
    }
	
	server {
        listen       443 ssl;
        server_name  www.moonknightsoft.com;
        # 注意 这里的位置都是指 nginx/con/ 下的相对位置 
		ssl_certificate      1_www.moonknightsoft.com_bundle.crt;
		# 注意 下边这行空格只能有一个
        ssl_certificate_key 2_www.moonknightsoft.com.key;
		ssl_session_cache  shared:SSL:1m;
        ssl_session_timeout 5m;		
        ssl_ciphers HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers on;
		
		location / {
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_set_header Host $http_host;
			proxy_set_header X-Forwarded-Proto https;
			proxy_redirect off;
			proxy_connect_timeout      240;
			proxy_send_timeout         240;
			proxy_read_timeout         240;
			proxy_pass http://community;
		}
    }
	
	# 服务2 （多个服务配置多份即可）
	upstream teacher {
        server 127.0.0.1:8082;
    }
	
    server {
		listen       80;
		server_name  teacher.moonknightsoft.com;
		rewrite ^(.*) https://$server_name$1 permanent;
    }
	
	server {
        listen       443 ssl;
        server_name  teacher.moonknightsoft.com;
	ssl_certificate      1_teacher.moonknightsoft.com_bundle.crt;	
        ssl_certificate_key 2_teacher.moonknightsoft.com.key;
	ssl_session_cache  shared:SSL:1m;
        ssl_session_timeout 5m;
        ssl_ciphers HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers on;

		location / {
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_set_header Host $http_host;
			proxy_set_header X-Forwarded-Proto https;
			proxy_redirect off;
			proxy_connect_timeout      240;
			proxy_send_timeout         240;
			proxy_read_timeout         240;
			proxy_pass http://teacher;
        }
    }
}

三、tomcat 配置

nginx配置了 ssl 证书了，tomcat 就无需配置ssl证书了。tomcat只要做好应用的配置即可。
注意点：
1.proxyPort=“443” 必须要
2.Valve RemoteIpValve 必须要
