nginx check_http_send type=http 查检测不到后端TOM的存活

原因:定位到../conf/server.xml中

 <Connector port="8020" protocol="org.apache.coyote.http11.Http11NioProtocol"

               executor="tomcatThreadPool"

               connectionTimeout="20000"

               URIEncoding="UTF-8"

               enableLookups="false"

               redirectPort="8443"

               disableUploadTimeout="true" />

修改上面代码为:

 <Connector port="8020" protocol="HTTP/1.1"

                connectionTimeout="20000"

                redirectPort="8443" />

问题解决
