本文介绍如何将Tomcat服务器从8080端口迁移至443端口，并启用HTTPS服务。通过修改server.xml文件中的Connector标签即可实现端口切换。若遇到启动失败错误，需使用root权限启动Tomcat。

因为小程序用到https和443端口
之前已经成功配置了ssl证书，现在开始更改端口

之前的配置server.xml：

<Connector port="8080" protocol="HTTP/1.1" SSLEnabled="true"
    maxThreads="150" scheme="https" secure="true"
    keystoreFile="conf/baidu.com.jks"
    keystorePass="48os1yb85ss2h"
    clientAuth="false" sslProtocol="TLS" />

更改为：

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
    maxThreads="150" scheme="https" secure="true"
    keystoreFile="conf/baidu.com.jks"
    keystorePass="48os1yb85ss2h"
    clientAuth="false" sslProtocol="TLS" />

对就是这么简单，只改一个端口，（之前我改了很多地方的端口，越改越乱，到最后发现原来只改这里的就可以了）

注意：你改完后，重启tomcat发现：

这时候你要淡定：

你要用root用户去启动你的tomcat
