1、申请全球DNS 域名

2、根据域名申请https证书

3、vi  server.xml

1、8443 改为443，设置证书配置
修改区域
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true">
        <SSLHostConfig>
            <Certificate certificateKeystoreFile="conf/localhost-rsa.jks"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>

修改为
<Connector port="443" protocol="org.apache.coyote.http11.Http11NioProtocol"
               maxThreads="150" SSLEnabled="true">
        <SSLHostConfig>
            <Certificate certificateKeystoreFile="/usr/local/java/tomcat8/conf/key/2018sslcert_GlobalSign_pwdBJCA.....pfx"
                         certificateKeystorePassword="123456"
                         certificateKeystoreType="PKCS12"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>
    
注释：certificateKeystoreFile 为证书路径，certificateKeystorePassword 为证书生成时设置的密码，certificateKeystoreType为类型，pfx 格式证书类型就是PKCS12



2、设置把8080端口改为80，设置访问80端口重定向到443端口
修改前
    <Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

修改为
<Connector port="80" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="443" />

3、8009重定向到443
修改前
<!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
修改后
 <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" protocol="AJP/1.3" redirectPort="443" />

4、vi  web.xml

在 </welcome-file-list>下面插入如下内容即可

<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> 

注：设置完第4步骤访问80 端口才会自动重定向到443，（前3步骤只是加入了全球服务器证书，可以通过443访问了）。

5、重启服务

../bin/shutdown.sh

../bin/start.sh
