這篇文章主要介紹了Nginx反向代理websocket配置實例,本文是專案需求配置成功後的總結,需要的朋友可以參考下
最近有一個需求，就是需要使用nginx 反向代理websocket，經過查找一番資料，目前已經測試通過，本文只做一個記錄
##複製代碼 代碼如下:
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
複製程式碼
程式碼如下：wget http://tengine.taobao.org/download/tengine-2.0.3.tar.gz
套件
複製程式碼 程式碼如下:yum -y install pcre*
yum -y install zlib*
yum -y install openssl*
複製程式碼
程式碼如下:tar -zxvf tengine-2.0.3.tar.gz cd tengine-2.0.3 ./configure --prefix=安装目录 make sudo make install
#複製程式碼
程式碼如下:
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.
worker_rlimit_nofile 65535;
events {
use epoll;
worker_connections 65535;
}

#websocket 需要加下这个
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
include /home/apps/tengine/conf/test.com;
}
複製程式碼
程式碼如下：upstream test.com {
server 192.168.1.5:9000;
}
server {
listen 80;
server_name test.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location ^~ /websocket {
proxy_pass http://test.com;
proxy_redirect off;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
上面nginx .conf 設定中的map $http_upgrade $connection_upgrade 的作用，參考http://www.ttlsa.com/nginx/using-nginx-map-method/
#此作用主要是根據客戶端請求中$ http_upgrade 的值，來建構改變$connection_upgrade 的值，也就是根據變數$http_upgrade 的值建立新的變數$connection_upgrade，所建立的規則就是{} 裡面的東西，請見配置：
##複製程式碼
程式碼如下:
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
