其实网上有很多安装的教程，这里简单放一些参考链接：

但应该有很多人和我一样，按照教程改了 tomcat 的 server.xml 后，启动是报错 Connector attribute SSLCertificateFile must be defined when using SSL with APR

以下是我成功的配置：

<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
               maxThreads="150" scheme="https" secure="true"
               sslProtocol="TLS"
               keystoreFile="${your jks file path}" 
               keystorePass="${your password}"
               clientAuth="false"/>

关键点：把 protocol=“HTTP/1.1” 改成 protocol=“org.apache.coyote.http11.Http11Protocol”，然后增加一个 sslProtocol=“TLS”
