centos - WARNING: Module not found [ssl] -

i trying install geoserver on centos folling installation documentation in geoserver website, have got error "warning: module not found [ssl]" after line "geoserver data dir /usr/share/geoserver/data_dir", can problem me?

this warning , not prevent operation. believe error common geoserver bundle comes jetty.

if need configure https support, i'd recommend investigating tomcat or wildly.
