案例说明：
前面一层nginx+Keepalived部署的LB,后端两台web服务器部署了多实例的tomcat，通过https方式部署nginx反向代理tomcat请求。配置一如下：

1）LB层的nginx配置访问http强制转到https[root@external-lb01 ~]# cat /data/nginx/conf/vhosts/80-www.kevin.com.conf
server { listen 80;
server_name kevin.com www.kevin.com;

}https反向代理的配置[root@external-lb01 ~]# cat /data/nginx/conf/vhosts/443-www.kevin.com.conf

}以上配置中，需要注意：访问https://www.kevin.com 要求和访问http://192.168.10.20:9040/portal-pc/ 结果一致
访问https://www.kevin.com/portal-pc 要求和访问https://www.kevin.com 结果一致
2）后端两台机器192.168.10.20和192.168.10.21的tomcat配置。两台配置一致，这里以192.168.10.20配置为例：[root@bl2-app01 ~]# cat /data/release/projects/tomcat_app_9020/conf/server.xml
...... <Connector port="9020" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"/>
...... <Connector port="9029" protocol="AJP/1.3" redirectPort="8443" />
[root@bl2-app01 ~]# cat /data/release/projects/tomcat_portal_9040/conf/server.xml
......<Connector port="9040" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="4443" URIEncoding="UTF-8"/>
...... <Connector port="9049" protocol="AJP/1.3" redirectPort="4443" />
..... |
===============================================================================
配置二：也可以采用如下proxy_redirect配置（指定修改被代理服务器返回的响应头中的location头域跟refresh头域数值）（注意下面proxy_redirect里由http -> https的代理返回设置）

}======================温馨提示========================上面启用了proxy_redirect配置（http->https），配置中就不需要"proxy_set_header Host $host;"，即不需要"添加发往后端服务器的请求头"的配置了
|
================================================================================
如上，配置了80端口的http访问强制跳转为443端口的https访问方式：
1）如果域名配置为https的访问方式，则上面配置一和配置二都可以。
2）如果域名配置为http的访问方式，则如上配置一后，访问的结果都只会跳转到https的首页，故这种情况下需如上配置二。

}
} 如果想要访问http://bpm.kevin.com的结果不强制跳转为https://www.kevin.com，则需要启用proxy_redirect的配置：
[root@external-lb01 ~]# cat /data/nginx/conf/vhosts/bpm.kevin.com.conf

<Connector port="8001" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
<Connector port="8091" protocol="AJP/1.3" redirectPort="8443" />
//添加以下内容
<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" scheme="https" secure="false" keystoreFile="cert/gotom.pfx" keystoreType="PKCS12" keystorePass="214261272770418" clientAuth="false" SSLProtocol="TLSv1+TLSv1.1+TLSv1.2" ciphers="TLS_RSA_WITH_AES_128_CBC_SHA,TLS_RSA_WITH_AES_256_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_128_CBC_SHA256,TLS_RSA_WITH_AES_256_CBC_SHA256" />

配置好后重新启动nginx，tomcat，就可以https访问了，这也是现在比较常见采用的配置方式 。
二、nginx采用https，tomcat采用http1）nginx配置httpsupstream https_tomcat_web { server 127.0.0.1:8001;
} server { listen 443;
server_name www.test.com;
index index.html;
root /var/www/html/test;
ssl on;
ssl_certificate /etc/nginx/go.pem;
ssl_certificate_key /etc/nginx/go.key;
ssl_session_timeout 5m;
ssl_protocols SSLv2 SSLv3 TLSv1.2;

ssl_prefer_server_ciphers on;
location ~ ^/admin {
proxy_pass http://https_tomcat_web; //是http的
proxy_redirect off;
proxy_set_header Host $host;

}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
} 2）tomcat的http配置,配置文件server.xml<Service name="Catalina">
<Connector port="8001" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" /> //在这里重新定向到了443端口
<Connector port="8091" protocol="AJP/1.3" redirectPort="443" />
..................省略....................

重启nginx，tomcat，https就配置好了。 |
=====================Nginx非80端口代理转发配置=======================
注意：nginx使用非80端口转发时，proxy_set_header配置中的$host后面一定要跟端口！如下篇配置（proxy_set_header Host $host:8080; ）。否则访问会有问题！（当https访问时，已配置了http强转https，则$host后面不需加443端口）。
