nginx 10054报错问题解决方案

使用nginx代理，端口8000。tomcat用于后端服务器，端口8080。nginx的error.log中报如下错误：

2018/09/21 09:08:06 [error] 12488#11600: *27 WSARecv() failed (10054: An existing connection was forcibly closed by the remote host) while reading upstream, client: 192.168.11.234, server: 192.168.11.234, request: "POST /kjdp_login HTTP/1.1", upstream: "http://192.168.11.234:8080/login", host: "192.168.11.234:8000", referrer: "http://192.168.11.234:8000/xxxx/yyyy/zzzz.html"

解决步骤：

1.修改tomcat的server.xml配置。配置信息如下：

<Executor name="tomcatThreadPool" namePrefix="req-exec-"
    maxThreads="2048"
    maxHttpHeaderSize="8192"
    minSpareThreads="512"
    maxSpareThreads="1024"
    maxIdleTime="30000"/>
    
    <Connector executor="tomcatThreadPool"
    port="8080"
    protocol="org.apache.coyote.http11.Http11NioProtocol"
    connectionTimeout="10000"
    redirectPort="8443"
    acceptCount="1024"
    enableLookups="false"
    URIEncoding="utf-8"   
    compression="on"/>

2.修改nginx的nginx.conf文件，配置信息如下：

http{}中添加：

　　keepalive_requests 8192;
　　keepalive_timeout 180s 180s;

server{

　　location / {

　　　　proxy_http_version 1.1;

　　}

}
