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 /app/webapp/tomcat/https/server.keystore -destkeystore /app/webapp/tomcat/https/server.keystore -deststoretype pkcs12".
[webapp@machina https]$

修改配置server.xml

[webapp@machina conf]$ pwd
/app/webapp/tomcat/apache-tomcat-7.0.88/conf
[webapp@machina conf]$ vi server.xml

改为：

保存：
:wq

修改https的tomcat里的默认端口8443（也可不改，用默认的）。
这里修改为18003。共修改三处。另外两处是注释里的，可不修改。

修改tomcat的web.xml，强制http跳转到https

[webapp@machina conf]$ pwd
/app/webapp/tomcat/apache-tomcat-7.0.88/conf
[webapp@machina conf]$ vi web.xml

后面加上这样一段：

    
            
        CLIENT-CERT    
        Client Cert Users-only Area    
        
        
            
            
            SSL    
            /*    
            
            
            CONFIDENTIAL
