Nginx設定總結

修改nginx伺服器配置，在conf檔案下的nginx.conf檔。

<code><span>#user nobody;   #运行用户</span><span>#worker_processes 1;    #启动进程数，通常设置成和cpu数目相同</span><span>#error_log /var/log;    #错误日志</span>
events {
    worker_connections <span>1024</span>;<span>#单个后台work process进程最大并发链接数</span>
}

<span>#设定http服务器</span>
http{
     <span>#设定mime类型,类型由mime.type文件定义</span>
    include       /etc/nginx/mime.types;
    default_type  <span>application</span>/octet-stream;
    <span>#设定日志格式</span>
    access_log    /var/<span>log</span>/nginx/access.<span>log</span>;
    sendfile <span><span>on</span></span>;
    <span>#连接超时时间</span><span>#keepalive_timeout  0;</span>
    keepalive_timeout  <span>65</span>;
    tcp_nodelay        <span><span>on</span></span>;

    <span>#集群中的所有后台服务器的配置信息，用于负载均衡</span>
    upstream local_tomcat{
        server <span>192.168</span><span>.0</span><span>.111</span>:<span>80</span>;
        server <span>192.168</span><span>.0</span><span>.109</span>:<span>8080</span>;
    }
    server{
        listen <span>8090</span>;    <span>#当前代理服务器监听端口</span>
        server_name  localhost:<span>80</span>;  <span>#监听后要转到地址</span><span>#charset koi8-r;</span><span>#access_log  logs/host.access.log  main;</span>        location / {    <span>#location表示匹配路径，/表示所有请求</span>
        root   html;  <span>#静态文件存放的路径</span>
        index  index.html index.htm;  <span>#没有主页时，此为主页，可多个</span>
        }

        <span>#error_page  404              /404.html;</span><span># redirect server error pages to the static page/50x.html</span>
        error_page   <span>500</span><span>502</span><span>503</span><span>504</span>  /<span>50</span>x.html;
        location = /<span>50</span>x.html {
            root   html;
        }
    }
}
</code>

常見問題總結：
1. nginx+tomcat影響request值
request.getScheme() //總是 http，而不是實際的http或https
request.isSecure() //總是false（因為總是http）
request.getRemoteAddr() //總是 nginx 請求的 IP，而不是使用者的IP
request.getRequestURL() //總是 nginx 請求的URL 而不是使用者實際請求的 URL
request.getServerName //總是nginx請求的ip
request.getServerPort //總是nginx請求的連接埠
response.sendRedirect( 相對url ) //總是重新導向到 http 上 （因為認為目前是 http 要求）
解決方法：
修改nginx設定：

<code>proxy_<span>set</span>_header Host <span>$host</span>;   <span>#解决getRequestURL、getServerName、getServerPort问题</span>
proxy_<span>set</span>_header X-Real-IP <span>$remote_addr</span>;<span>#把真实的ip发送给转发的web服务器</span>
proxy_<span>set</span>_header X-Forwarded-For <span>$proxy_add_x_forwarded_for</span>;<span>#解决request.getScheme()只能返回http而不是https问题</span></code>

設定tomcat的server.xml的Engine模組，設定一個value

<code><span>< <span>Valve</span><span>className</span>=<span>"org.apache.catalina.valves.RemoteIpValve"</span><span>remoteIpHeader</span>=<span>"X-Forwarded-For"</span><span>protocolHeader</span>=<span>"X-Forwarded-Proto"</span><span>protocolHeaderHttpsValue</span>=<span>"https"</span> /></span></code>
