Tengine 四层代理：

Tengine 四层代理：

1 ） 安装tengine ( nginx1.9 以上版本 编译以后要支持stream 模块)

1.1 ) tengine(nginx) 一定要是nginx-1.9.X 以上的版本,否则不支持stream功能：
/data/nginx/sbin/nginx -V
Tengine version: Tengine/2.3.2
nginx version: nginx/1.17.3
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-39) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
......

1.2 ） 编译安装tengine-2.3.2 开启的功能略有改变：
wget http://tengine.taobao.org/download/tengine-2.3.2.tar.gz && tar -zxf tengine-2.3.2.tar.gz 
cd tengine-2.3.2
./configure --prefix=/data/nginx  --user=fmw --group=fmw --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre   --with-stream --with-stream=dynamic --with-stream_ssl_module --with-stream_realip_module

# --with-http_concat_modul  这个参数可能因为是开发版本 还没有加入2.3.2版本,静待后面的正式版本.
# --with-stream   --with-stream=dynamic   --with-stream_ssl_module   --with-stream_realip_module
# 这三个开启的就是nginx的stream 功能.

make && make install

2 ） 配置 nginx 的stream 模块 来做TCP代理

2.1 ） 创建配置目录：
mkdir -p /data/nginx/{pid,temp,proxycache
mkdir -p /data/nginx/conf/tcp/ 
###########################  四层代理的配置 #####################################
##  注意： 1 ) nginx 版本要在1.9 以上, tengine 基于那个版本开发的 去官网查
##  注意： 2 ）编译时要加入--with-stream --with-stream_ssl_module   --with-stream_realip_module
##            安装好的可以通过 nginx -V 来查看具体编译的参数. 没有加入的重新编译加入即可.
##  注意： 3 ）主配置文件一定要引入  nginx_stream_modele.so;
vim tcp.conf

stream {
   upstream  redis_host {
    server 10.10.116.206:6379;
  }

  server {
    listen 10.10.4.209:6379;
    proxy_connect_timeout 5s;
    proxy_timeout 5s;
    proxy_pass  redis_host;
  }

}
