最近访问一部分网站时,出现如下图所示 “ 此网站无法提供案例连接,客户端和服务器不支持一般 SSL 协议版本或加密套件 ” 的问题。
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。
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。
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
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)
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"
/>
