nginx(https)反向代理tomcat(http)的实现教程

nginx和tomcat都动了配置

nginx.conf 配置如下：

画重点：proxy_set_header X-Forwarded-Proto $scheme; 另外因为ngrok也需要80端口，新增了ip分别绑定在不同ip上。

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;


# Load dynamic modules. See /usr/share/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;


events {
    worker_connections 1024;
}


http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for" "$host"';


    access_log  /var/log/nginx/access.log  main;
    #access_log off;
    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;


    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;
    charset utf-8;


    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;


   upstream tomcat {
        server 127.0.0.1:8080;
   }
   # resolver      8.8.8.8;


    server {
        listen       172.31.xx.228:80;
        server_name  *.ngrok.bob.kim;


        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;
 
        location / {
             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-Nginx-Proxy true;
             proxy_set_header Connection "";
             client_max_body_size 50m;   
             client_body_buffer_size 128k; 
             proxy_connect_timeout 90; 
             proxy_read_timeout 90;
             proxy_buffer_size 4k;       
             proxy_buffers 6 128k;        
             proxy_busy_buffers_size 256k;
             proxy_temp_file_write_size 256k;
             proxy_redirect  off; 
             proxy_pass http://172.31.xx.229:80;
       
       } 
    }


    server {
        listen       172.31.xx.228:80;
        server_name  bob.kim;
        rewrite ^(.*) https://$server_name$1 permanent;
    }




# Settings for a TLS enabled server.


    server {
        listen     172.31.xx.228:443;
        server_name  bob.kim;
        ssl on;


        ssl_certificate "/etc/pki/nginx/bobkim.pem";
        ssl_certificate_key "/etc/pki/nginx/private/bobkim.key";
        ssl_session_timeout  5m;
        ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;


        # Load configuration files for the default server block.
        include /etc/nginx/default.d/*.conf;


        location / {
             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 $scheme;
             proxy_set_header X-Scheme $scheme; 
             proxy_set_header X-SSL-Protocol $ssl_protocol;
             proxy_set_header X-HTTPS-Protocol $ssl_protocol;
             proxy_set_header X-Nginx-Proxy true;
             proxy_set_header Connection "";
             proxy_redirect  off;
             proxy_pass http://tomcat;
        }
    }


}



tomcat  server.xml配置在最后添加如下：

<Valve className="org.apache.catalina.valves.RemoteIpValve"  
                  remoteIpHeader="x-forwarded-for"  
                  remoteIpProxiesHeader="x-forwarded-by"  
                  protocolHeader="x-forwarded-proto"/>



完整的配置
