第一步

  <Connector executor="tomcatThreadPool"
               port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

改：

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

第二步

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

改：

<Connector port="8009" protocol="AJP/1.3" redirectPort="443"    />

第三步

    <!--
    <Connector port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol"
               maxThreads="150" SSLEnabled="true" >
        <UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
        <SSLHostConfig>
            <Certificate certificateKeyFile="conf/localhost-rsa-key.pem"
                         certificateFile="conf/localhost-rsa-cert.pem"
                         certificateChainFile="conf/localhost-rsa-chain.pem"
                         type="RSA" />
        </SSLHostConfig>
    </Connector>
    -->

改：

<Connector port="443" protocol="org.apache.coyote.http11.Http11Nio2Protocol" maxThreads="150" SSLEnabled="true" defaultSSLHostConfigName="默认域名" >   
	<UpgradeProtocol className="org.apache.coyote.http2.Http2Protocol" />
	  <SSLHostConfig hostName="域名1" >   
		<Certificate certificateKeystoreFile="conf/域名1-tomcat.pfx" certificateKeystorePassword="域名1密码" type="RSA"/>   
	  </SSLHostConfig>   
	  	  <SSLHostConfig hostName="域名2">   
		<Certificate certificateKeystoreFile="conf/域名2-tomcat.pfx" certificateKeystorePassword="域名2密码" type="RSA"/>   
	  </SSLHostConfig>   
</Connector>

第四步

修改host

      <Host name="域名1"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
	    <Context  path="" reloadable="true" docBase="webapps下项目名称"/>

      </Host>
	  <Host name="域名2"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />
		<Context  path="" reloadable="true" docBase="webapps下项目名称"/>

      </Host>

记得开放80和443端口
