这篇文章主要给大家介绍了关于nginx https反向代理tomcat的2种实现方法,第一种方法是nginx配置https,tomcat也配置https,第二种方法是nginx采用https,tomcat采用http,文中通过示例代码介绍的非常详细,需要的朋友可以参考下。
反向代理
在计算机世界里,由于单个服务器的处理客户端(用户)请求能力有一个极限,当用户的接入请求蜂拥而入时,会造成服务器忙不过来的局面,可以使用多个服务器来共同分担成千上万的用户请求,这些服务器提供相同的服务,对于用户来说,根本感觉不到任何差别。
nginx做前端代理分发,tomcat处理请求。nginx反代tomcat实现https有二个方法。
一、nginx配置https,tomcat也配置https
1、nginx配置https

2、tomcat的https配置,配置文件server.xml
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | <Service name="Catalina"> <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" /> ..................省略.................... </Service> |

配置好后重新启动nginx,tomcat,就可以https访问了,这也是我现在采用的配置方式 。
二、nginx采用https,tomcat采用http
1、nginx配置https

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 | upstream 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_ciphers ALL:!ADH:!EXPORT56:RC4 RSA: HIGH: MEDIUM: LOW: SSLv2: EXP; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4; ssl_prefer_server_ciphers on; location ~ ^/admin { proxy_pass http://https_tomcat_web; //是http的 proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 100m; client_body_buffer_size 256k; proxy_connect_timeout 60; proxy_send_timeout 30; proxy_read_timeout 30; proxy_buffer_size 8k; proxy_buffers 8 64k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } 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
?
1 2 3 4 5 6 7 8 9 10 11 | <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.................... </Service> |

重启nginx,tomcat,https就配置好了。
不管是第一种方法,还是第二种方法,如果通过http,直接访问8001端口,浏览器都会提示你不安全的访问,因为本身是http,确被重定向到了https。
