生成keystore

keytool -genkeypair -alias "server" -keyalg "RSA" -validity "365" -keystore "/app/webapp/tomcat/https/server.keystore"

[webapp@machina https]$ pwd
/app/webapp/tomcat/https
[webapp@machina https]$ keytool -genkeypair -alias "server" -keyalg "RSA" -validity "365" -keystore "/app/webapp/tomcat/https/server.keystore"
Enter keystore password:  
Re-enter new password: 
What is your first and last name?
  [Unknown]:  10.13.22.102
What is the name of your organizational unit?
  [Unknown]:  ai
What is the name of your organization?
  [Unknown]:  ai
What is the name of your City or Locality?
  [Unknown]:  gz
What is the name of your State or Province?
  [Unknown]:  gd
What is the two-letter country code for this unit?
  [Unknown]:  cn
Is CN=10.13.22.102, OU=ai, O=ai, L=gz, ST=gd, C=cn correct?
  [no]:  yes

Enter key password for <server>
        (RETURN if same as keystore password):  
Re-enter new password: 

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

    <!--
    <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" />
    -->
 

改為：

    <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS" 
               keystoreFile="/app/webapp/tomcat/https/server.keystore" keystorePass="123456"/>
 

保存：
:wq

修改https的tomcat裏的默認端口8443（也可不改，用默認的）。
這裏修改為18003。共修改三處。另外兩處是註釋裏的，可不修改。

    <Connector port="18002" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

    <Connector port="18002" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="18003" />

    <Connector port="18003" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
               clientAuth="false" sslProtocol="TLS"
               keystoreFile="/app/webapp/tomcat/https/server.keystore" keystorePass="123456"/>

    <Connector port="8009" protocol="AJP/1.3" redirectPort="18003" />

修改tomcat的web.xml，強制http跳轉到https

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

</welcome-file-list>後面加上這樣一段：

    <login-config>    
        <!-- Authorization setting for SSL -->    
        <auth-method>CLIENT-CERT</auth-method>    
        <realm-name>Client Cert Users-only Area</realm-name>    
    </login-config>    
    <security-constraint>    
        <!-- Authorization setting for SSL -->    
        <web-resource-collection >    
            <web-resource-name >SSL</web-resource-name>    
            <url-pattern>/*</url-pattern>    
        </web-resource-collection>    
        <user-data-constraint>    
            <transport-guarantee>CONFIDENTIAL</transport-guarantee>    
        </user-data-constraint>    
    </security-constraint>
