Warning:
The JKS keystore uses a proprietary format. It is recommended to migrate to PKCS12 which is an industry standard format using "keytool -importkeystore -srckeystore /root/.keystore -destkeystore /root/.keystore -deststoretype pkcs12".

mv /root/.keystore /var/lib/tomcat7/conf/

vi /var/lib/tomcat7/conf/server.xml

<Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
clientAuth="false" sslProtocol="TLS" keystoreFile="/var/lib/tomcat7/conf/.keystore" keystorePass="xxxxx" />

service tomcat7 restart

netstat -nplt | grep 8443 ??（此时为8443端口）

apt-get install authbind
