使用nginx反向代理tomcat服务，走https经常自动跳转到http 解决方案_nginx代理怎么避免跳转

使用nginx反向代理tomcat服务，走https经常自动跳转到http，遇到此种问题，我们需要做两方面设置：

1. nginx中配置

在nginx中 要配置 proxy_set_header X-Forwarded-Proto $scheme;

如下所示：

nginx.conf 文件

        location ^~ /infomation/ {
            proxy_redirect off;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_pass http://serverInformation;
        }

upstream.conf文件

    upstream serverInformation {
        server 192.168.0.150:10100;
    }

2. tomcat中配置

在tomcat server.xml中做如下配置

    <Connector port="10100" protocol="HTTP/1.1"
               connectionTimeout="20000" minSpareTHreads="30"
               redirectPort="8443" URIEncoding="utf-8" />

和

    <Engine name="Catalina" defaultHost="localhost">
 
      <!--For clustering, please take a look at documentation at:
          /docs/cluster-howto.html  (simple how to)
          /docs/config/cluster.html (reference documentation) -->
      <!--
      <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
      <!-- Use the LockOutRealm to prevent attempts to guess user passwords
           via a brute-force attack -->
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <!-- This Realm uses the UserDatabase configured in the global JNDI
             resources under the key "UserDatabase".  Any edits
             that are performed against this UserDatabase are immediately
             available for use by the Realm.  -->
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
 
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
 
        <!-- SingleSignOn valve, share authentication between web applications
             Documentation at: /docs/config/valve.html -->
        <!--
        <Valve className="org.apache.catalina.authenticator.SingleSignOn" />
        -->
 
        <!-- Access log processes all example.
             Documentation at: /docs/config/valve.html
             Note: The pattern used is equivalent to using pattern="common" -->
        <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" />
 
        <Valve className="org.apache.catalina.valves.RemoteIpValve" remoteIpHeader="X-Forwarded-For" protocolHeader="X-Forwarded-Proto" protocolHeaderHttpsValue="https"/>
 
      </Host>
    </Engine>
  </Service>
</Server>
