保存富文本文字内容太多,提示nginx 414 Request-URI Too Large及tomcat报错

作项目时碰到富文本的内容太多,提交请求时,请求头过长报错,先是nginx报错,
缘由是请求头的长度超出了nginx限制了,增长client_header_buffer_size和large_client_header_buffers的值,
若是nginx.conf文件不存在这两个参数,新增便可.

贴一下个人nginx.conf配置,倒数两行就是须要增长的参数.

user  root;
worker_processes  2;

pid  /var/run/nginx.pid;

events {
    worker_connections  4096;
}


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

    sendfile        on;
    tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;
    gzip_disable "msie6";
    gzip_proxied any;
    gzip_comp_level 6;
    gzip_buffers 16 16k;

    gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript
    image/jpeg image/gif image/png image/bmp image/x-icon;

    client_header_buffer_size 512k;
    large_client_header_buffers 4 512k;

    include /usr/local/nginx/tomcat*.conf;
}

配置完nginx.conf重启后,没有继续报错Request-URI Too Large错误了,可是看请求没有响应,查看了下tomcat的日志,发现报错java.lang.IllegalArgumentException: Request header is too large
,网上查了下,是请求头超出了tomcat默认的head大小,处理办法：在server.xml中增长maxHttpHeaderSize

<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"  maxPostSize="0" maxHttpHeaderSize ="102400"/>

可是加完仍是报相同的错,因而maxHttpHeaderSize又加了两个0,就解决了,客户上传的文档太大了,你们根据本身的需求调整tomcat和nginx的参数大小.

后面使用nginx上传图片时,提示413 Request Entity Too Large 错误
解决办法: 在nginx设置文件上传最大大小为2MB, 根据实际状况调整

client_max_body_size 2m;
