Nginx反向代理websocket配置实例

代码如下:

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

代码如下:

wget http://tengine.taobao.org/download/tengine-2.0.3.tar.gz

代码如下:

yum -y install pcre*
yum -y install zlib*
yum -y install openssl*

代码如下:

tar -zxvf tengine-2.0.3.tar.gz cd tengine-2.0.3 ./configure --prefix=安装目录 make sudo make install

代码如下:

user apps apps;
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_processes auto
# worker_cpu_affinity auto

error_log  logs/error.log;

pid        logs/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.
