nginx转发tomcat之https不生效

1、修改tomcat配置server.xml，让它从请求头中的X-Forwarded-Proto读取

<!-- xpath：//Server/Service/Engine/Value -->

<Valve className="org.apache.catalina.valves.RemoteIpValve"
        remoteIpHeader="X-Forwarded-For"
        protocolHeader="X-Forwarded-Proto"
        protocolHeaderHttpsValue="https"/>

2、nginx.conf增加配置

location / {
    ...  
    proxy_set_header X-Forwarded-Proto  $scheme;
    ...
}
