Solr4.6 Expected content type application/octet-stream but got text/html 解决办法
自从用nginx-1.2.3为solr4.6做负载均衡之后,只要是删除操作,就报如下堆栈:
org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Expected content type application/octet-stream but got text/html. <html>
<head><title>411 Length Required</title></head>
<body bgcolor="white">
<center><h1>411 Length Required</h1></center>
<hr><center>nginx/1.2.3</center>
</body>
</html>

不仅删除操作不成功,写操作虽然单元测试通过,但是上solr管理界面上查,并没有真正的写进去。
问题显然出在Nginx上,因为没有打通Nginx之前,所有CRUD单元测试都是正常的。返回结果也提示是Nginx-1.2.3把这个请求拦截了。
根据提示,我修改了nginx.conf的配置文件:
default_type application/octet-stream; ——>default_type text/html;
重启nginx, ./nginx -s reload。删除操作报同样的错误。
最终怀疑nginx的版本的问题,是不是我的solr太新了,4.6是当前solr的最新版本,会不会跟比较老的nginx-1.2.3不兼容?
于是上nginx官网download最新的nginx-1.5.9的代码包。放到服务器上,编译安装好之后。停掉老的1.2.3,重新配置1.5.9。
启动nginx-1.5.9,重新执行删除和写的单元测试,没有报异常。去solr4.6的管理界面查看数据,没有问题。
分享下我的解决办法,至于真正的原因,我也不是很清楚,慢慢的熟悉solr4.6吧。希望有经验的大神回复下,指出异常的根本原因。
