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.confserver { listen 80; server_name kevin.com www.kevin.com; access_log /data/nginx/logs/www.kevin.com-access.log main; error_log /data/nginx/logs/www.kevin.com-error.log; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } return 301 https://$server_name$request_uri;}https反向代理的配置[root@external-lb01 ~]# cat /data/nginx/conf/vhosts/443-www.kevin.com.confupstream scf_cluster { ip_hash; server 192.168.10.20:9020; server 192.168.10.21:9020; }upstream portal_cluster { ip_hash; server 192.168.10.20:9040; server 192.168.10.21:9040; }upstream file_cluster{ ip_hash; server 192.168.10.20:9020; }upstream workflow_cluster{ ip_hash; server 192.168.10.20:9020; server 192.168.10.21:9020; }upstream batch_cluster{ server 192.168.10.20:9020; server 192.168.10.21:9020; }server { listen 443; server_name www.kevin.com; ssl on; ssl_certificate /data/nginx/conf/ssl/kevin.cer; ssl_certificate_key /data/nginx/conf/ssl/kevin.key; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_session_cache shared:SSL:1m; ssl_session_timeout 5m; ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4:!DH:!DHE; ssl_prefer_server_ciphers on; access_log /data/nginx/logs/www.kevin.com-access.log main; error_log /data/nginx/logs/www.kevin.com-error.log; error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } rewrite /portal-pc https://www.kevin.com break; location / { proxy_pass http://portal_cluster/portal-pc/; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_redirect off; } location /scf { proxy_pass http://scf_cluster/scf; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_redirect off; } location /msdp-file { proxy_pass http://file_cluster/msdp-file; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_redirect off; } location /upload { proxy_pass http://file_cluster/upload; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_redirect off; } location /activiti-workflow-console { proxy_pass http://workflow_cluster/activiti-workflow-console; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_redirect off; } location /batch-framework-web { proxy_pass http://batch_cluster/batch-framework-web; proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504 http_404; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto http; proxy_redirect off; } }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）

================================================================================
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。

一、nginx配置https，tomcat也配置https1）nginx配置httpsupstream https_tomcat_web { server 127.0.0.1:8443; } 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 https://https_tomcat_web; //是https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https配置,配置文件server.xml<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_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 $proxy_add_x_forwarded_for; client_max_body_size 100m; client_body_buffer_size 256k; proxy_connect_timeout 60; proxy_send_timeout 30; proxy_read_timeout 30; proxy_buffer_size 8k; proxy_buffers 8 64k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } } 2）tomcat的http配置,配置文件server.xml<Service name="Catalina"> <Connector port="8001" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="443" /> //在这里重新定向到了443端口 <Connector port="8091" protocol="AJP/1.3" redirectPort="443" /> ..................省略.................... </Service> 重启nginx，tomcat，https就配置好了。 |
=====================Nginx非80端口代理转发配置=======================
注意：nginx使用非80端口转发时，proxy_set_header配置中的$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）。
