nginx做proxy时，出现Cannot assign requested address错误

[朱茂海]

现在需要是，所有请求/connect.php文件的，全部反向代理到其它服务器。下面是我写的规则

location =/connect.php

        {

proxy_pass http://10.134.12.42:8082;

 proxy_set_header       Host            $host;

}

但访问/connect.php时出现502，查看10.134.12.42日志发现如下错误：

2013/05/13 17:27:35 [crit] 10928#0: *101812971 connect() to 10.134.12.42:8082 failed (99: Cannot assign requested address) while connecting to upstream, client: 10.134.12.42, server: xxx, request: "GET /connect.php?mod=login&op=init&referer=forum.php%3Fmod%3Dviewthread%26tid%3D225303&statfrom=login HTTP/1.0", upstream: "http://10.134.12.42:8082/connect.php?mod=login&op=init&referer=forum.php%3Fmod%3Dviewthread%26tid%3D225303&statfrom=login", host: "xxx", referrer: "http://xxxx/forum.php?mod=viewthread&tid=225303"

求解，谢谢各位。

这里你把你系统中的临时端口用尽了。建议启用 ngx_proxy 模块的 HTTP 1.1 支持和连接池支持。
