nginx反向代理報錯400
阿新 • • 發佈：2019-01-02
當用nginx做負載均衡的時候，nginx的配置檔案如下：
upstream server_pools {
server 10.0.0.7:80 weight=1;
server 10.0.0.8:80 weight=1;
當客戶端訪問時出現報錯如下：
[[email protected] ~]# curl www.hahaetiantian.org
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>400 Bad Request</title>
</head><body>
<h1>Bad Request</h1>
<p>Your browser sent a request that this server could not understand.<br />
</p>
<p>Additionally, a 400 Bad Request
error was encountered while trying to use an ErrorDocument to handle the request.</p>
</body></html>
[ 檢視日誌報錯並不能找到原因，但是根據400報錯以及對http協議的原理了解得知是因為請求頭的原因，最後在網上找到解決辦法，原因是因為upstream後面的名稱有下劃線使得代理無法識別，修改如下：
upstream server-pools {
server 10.0.0.7:80 weight=1;
server 10.0.0.8:80 weight=1;然後再次訪問結果如下：
[[email protected] ~]# curl www.etiantian.org
