Nginx反向代理websocket配置实例
最近有一个需求，就是需要使用nginx反向代理websocket，经过查找一番资料，目前已经测试通过，本文只做一个记录
注：看官方文档说Nginx在1.3以后的版本才支持websocket反向代理，所以要想使用支持websocket的功能，必须升级到1.3以后的版本，因此我这边是下载的Tengine的最新版本测试的
1.下载tengine最近的源码
wgethttp://tengine.taobao.org/download/tengine-2.0.3.tar.gz
2.安装基础的依赖包
yum-yinstallpcre* yum-yinstallzlib* yum-yinstallopenssl*
3.解压编译安装
tar-zxvftengine-2.0.3.tar.gzcdtengine-2.0.3./configure--prefix=安装目录makesudomakeinstall
nginx.conf的配置如下：
userappsapps; worker_processes 4;#这个由于我是用的虚拟机，所以配置的4，另外tengine可以自动根据CPU数目设置进程个数和绑定CPU亲缘性 #worker_processesauto #worker_cpu_affinityauto
error_log logs/error.log;
pid logs/nginx.pid;
