nginx+tomcat配置

直接上配置文件：
一、nginx的配置
nginx.conf

#user  nobody;
worker_processes 1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';
    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;

    server {
        listen 80;
        server_name www.aaa.cn aaa.cn m.aaa.cn;
        charset utf-8;
        rewrite ^(.*)$ https://$host$1 permanent;
    }


    # HTTPS server
    #
    server {
        listen       443 ssl;
        server_name  www.aaa.cn aaa.cn m.aaa.cn;
        charset utf-8;

        ssl_certificate      cert/1_www.aaa.cn_bundle.crt;
        ssl_certificate_key  cert/2_www.aaa.cn.key;
        ssl_session_cache    shared:SSL:1m;
        ssl_session_timeout  5m;
        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers  on;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

        # access_log  logs/host.access.log  main;
        # error_page  404 /404.html;
        # redirect server error pages to the static page /50x.html;
        #
        proxy_intercept_errors on;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
        error_page   400 401 402 403 404 /40x.html;
        location = /40x.html {
            root html;
        }

        location / {
            proxy_pass http://127.0.0.1:8080;
            add_header 'Access-Control-Allow-Origin' '*';
            add_header 'Access-Control-Allow-Credentials' 'true';
            add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
            add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
            #重新定义或者添加发往后端服务器的请求头
            #给请求头中添加客户请求主机名
            proxy_set_header Host $host;
            #给请求头中添加客户端IP
            proxy_set_header X-Real-IP $remote_addr;
            #将$remote_addr变量值添加在客户端“X-Forwarded-For”请求头的后面，并以逗号分隔。
            #如果客户端请求未携带“X-Forwarded-For”请求头，$proxy_add_x_forwarded_for变量值将与$remote_addr变量相同
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #给请求头中添加客户端的Cookie
            proxy_set_header Cookie $http_cookie;
            #将使用代理服务器的主域名和端口号来替换。如果端口是80，可以不加。
            proxy_redirect off;
            #浏览器对 Cookie 有很多限制，如果 Cookie 的 Domain 部分与当前页面的 Domain 不匹配就无法写入。
            #所以如果请求 A 域名，服务器 proxy_pass 到 B 域名，然后 B 服务器输出 Domian=B 的 Cookie，
            #前端的页面依然停留在 A 域名上，于是浏览器就无法将 Cookie 写入。
            #不仅是域名，浏览器对 Path 也有限制。我们经常会 proxy_pass 到目标服务器的某个 Path 下，
            #不把这个 Path 暴露给浏览器。这时候如果目标服务器的 Cookie 写死了 Path 也会出现 Cookie 无法写入的问题。
            #设置“Set-Cookie”响应头中的domain属性的替换文本，其值可以为一个字符串、正则表达式的模式或一个引用的变量
            #转发后端服务器如果需要Cookie则需要将cookie domain也进行转换，否则前端域名与后端域名不一致cookie就会无法存取
            #取消当前配置级别的所有proxy_cookie_domain指令
            #proxy_cookie_domain off;
            #与后端服务器建立连接的超时时间。一般不可能大于75秒；
            proxy_connect_timeout 30;
        }
    }
}

二、tomcat的配置。
