nginx，tomcat发布第一次访问不到问题

 

导致第一次空白页面,要么是超时，要么是http的头过大，nignx文件连接数过小

 

 

tomcat

maxHttpHeaderSize="102400"

 

 

严重: Error processing request

org.apache.coyote.http11.HeadersTooLargeException: An attempt was made to write more data to the response headers than there was room available in the buffer. Increase maxHttpHeaderSize on the connector or write less data into the response headers.

at org.apache.coyote.http11.AbstractOutputBuffer.checkLengthBeforeWrite(AbstractOutputBuffer.java:547)

 

 

 

nginx日志信息：

 upstream sent too big header while reading response header from upstream
