一、定位问题

点击浏览器中网址上面锁头出现如下：

然后点击网站安全链接，出现如下：

通过对比，可以看到，该域名因为使用的是 TLS 1.0，所以会出现问题，因为谷歌等大部分浏览器已经开始全面禁止TLS1.0了。所以我们需要升级我们的服务端支持TLS1.2以上。

二、升级TLS1.2

1、原理

在这里插入图片描述

之前架构

之前Tomcat是监听https的8443端口，在tomcat/conf/server.xml中配置如下：

<Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8" 
               connectionTimeout="20000"  
			compression="on"
           compressionMinSize="512"
           compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/csv,application/javascript,application/json,application/xml"
                />
<Connector  protocol="org.apache.coyote.http11.Http11Protocol" URIEncoding="UTF-8" port="8443" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false"     sslProtocol="TLS"  disableUploadTimeout="false" sslEnabledProtocols="TLSv1,TLSv1.1,TLSv1.2" 
    keystoreFile="../ssl3/sggk.jks" keystorePass="sggk123"
    ciphers="TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDH_ECDSA_WITH_AES_256_CBC_SHA,TLS_ECDH_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDH_ECDSA_WITH_AES_128_CBC_SHA,TLS_ECDH_RSA_WITH_AES_128_CBC_SHA,TLS_ECDH_ECDSA_WITH_RC4_128_SHA,TLS_ECDH_RSA_WITH_RC4_128_SHA,TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDH_ECDSA_WITH_3DES_EDE_CBC_SHA,TLS_ECDH_RSA_WITH_3DES_EDE_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA"
  />

虽然看到tomcat配置支持TLSv1.2，但是由于低版本支持不好，所以配置无效。

调整架构

所以我们需要通过nginx反向代理来监听HTTPS:8443端口，然后转发到tomcat的HTTP:8080

2、配置nginx

配置参考如下


worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
	underscores_in_headers on;#表示如果header name中包含下划线，则不忽略
  	#access_log  logs/access.log  main;
 	sendfile        on;
    keepalive_timeout  65;
    gzip  on;
    #服务器的集群  
    upstream  www_test {  #服务器集群名字   
		#ip_hash;
        server    127.0.0.1:8080  ;#服务器配置   weight是权重的意思，权重越大，分配的概率越大。  
        #server    127.0.0.1:9092  weight=1;  
    }  
	

    server {
    	listen       443 ssl;
        server_name  www.test.cn;

	    ssl_certificate      D:/Tomcat 7.0/ssl/www.test.cn.pem;
	    ssl_certificate_key  D:/Tomcat 7.0/ssl/www.test.cn.key;
	
	    ssl_session_cache    shared:SSL:1m;
	    ssl_session_timeout  5m;
		ssl_ciphers  HIGH:!aNULL:!MD5;
		ssl_prefer_server_ciphers  on;
        # 配置静态资源      
		location /pm/v4/{
			alias   "D:/Tomcat 7.0/webapps/pm/v4/";
		}
		location /pm/jslib/{
			alias   "D:/Tomcat 7.0/webapps/pm/jslib/";
		}
		location /pm/css/{
			alias   "D:/Tomcat 7.0/webapps/pm/css/";
		}
		location /pm/images/{
			alias   "D:/Tomcat 7.0/webapps/pm/images/";
		}
		location /pm/temp/{
			alias   "D:/Tomcat 7.0/webapps/pm/temp/";
		}
		location /pm/main4.0/{
			alias   "D:/Tomcat 7.0/webapps/pm/main4.0/";
		}
		
		location /pm{
			add_header Cache-Control 'no-store';
			client_max_body_size 300m;
			proxy_http_version 1.1;
			proxy_set_header Upgrade $http_upgrade;
			proxy_set_header Connection "upgrade";
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_set_header Host $http_host;
			proxy_redirect off;
			proxy_connect_timeout      1;
			proxy_send_timeout         240;
			proxy_read_timeout         240;
			proxy_pass http://www_test/pm;
		}
        
    }
	
}

注意两个ssl证书文件路径
ssl_certificate D:/Tomcat 7.0/ssl/www.test.cn.pem;
ssl_certificate_key D:/Tomcat 7.0/ssl/www.test.cn.key;
证书需要客户提供或者自己去阿里云或者腾讯云申请，它属于nginx专用证书，跟tomcat的不一样
可以参考：nginx配置阿里云/腾讯云申请的免费SSL证书（nginx配置https）

3、配置tomcat

去掉https的配置，只保留http即可

<Connector port="8080" protocol="HTTP/1.1" URIEncoding="UTF-8" 
               connectionTimeout="20000"  
			compression="on"
           compressionMinSize="512"
           compressableMimeType="text/html,text/xml,text/plain,text/javascript,text/csv,application/javascript,application/json,application/xml"
                />
