Tomcat8.5 / 9 安装ssl证书

Tomcat 8.5 以上版本支持 SNI （ 同IP可以安装多个证书 ）, 至少 jre 7 以上版本

<Connector port="8443"
           protocol="org.apache.coyote.http11.Http11Nio2Protocol"
           maxThreads="150"
           SSLEnabled="true"
           defaultSSLHostConfigName="tomcat.getssl.cn" >
    <SSLHostConfig hostName="tomcat.getssl.cn" >
        <Certificate certificateKeystoreFile="conf/getssl.cn.jks"
					certificateKeystorePassword="123456"
                     type="RSA" />       
    </SSLHostConfig>
    // 其他站点复制多个 SSLHostConfig
</Connector>

使用Apache证书安装SSL

 <Connector port="8443" protocol="org.apache.coyote.http11.Http11AprProtocol"
                          maxThreads="150" SSLEnabled="true">
          <SSLHostConfig>
                       <Certificate certificateKeyFile="conf/ssl/server.key"
                            certificateFile="conf/ssl/server.crt"
                            certificateChainFile="conf/ssl/server.ca-bundle"
                            type="RSA" />
         </SSLHostConfig>
 </Connector>

protocol 可选:

org.apache.coyote.http11.Http11NioProtocol - non blocking Java NIO connector
org.apache.coyote.http11.Http11Nio2Protocol - non blocking Java NIO2 connector
org.apache.coyote.http11.Http11AprProtocol - the APR/native connector.
