apache 做代理 报如下错误:The proxy server received an invalid response from an upstream

 
阅读更多

网站配置是apache+tomcat,tomcat没有报错,apache报错是:

The proxy server received an invalid response from an upstream server. 
The proxy server could not handle the request GET /. 
Reason: Error reading from remote server

解决的方法:

For circumstances where mod_proxy is sending requests to an origin server that doesn't properly implement keepalives or HTTP/1.1, there are two environment variables that can force the request to use HTTP/1.0 with no keepalive. These are set via the SetEnv directive. 
These are the force-proxy -request-1.0 and proxy -nokeepalive notes.

当mod_proxy向一个没有正确实现持久连接(KeepAlive)或HTTP/1.1的原始服务器发送请求的时候,可以通过设置两个环境变量来发送不带持久连接(KeepAlive)的HTTP/1.0请求。这两个变量是通过SetEnv指令设置的。 
以下是force-proxy -request-1.0和proxy -nokeepalive的例子:

编辑 httpd.conf增加这两行:

SetEnv force-proxy-request-1.0.1
SetEnv proxy-nokeepalive 1

之后重启下 apache 服务
