基于nginx和tengine的tcp*，负载均衡 安装和配置

先下载nginx_tcp_proxy_module模块。

1. wget https://github.com/yaoweibin/nginx_tcp_proxy_module/archive/master.zip  

2. 先看看自己原来nginx安装有哪些模块（编译参数）：

   [root@111]# /tengine/sbin/nginx -V
   Tengine version: Tengine/2.1.1 (nginx/1.6.2)
   built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC) 
   TLS SNI support enabled

   configure arguments: –prefix=/tengine –user=www –group=www –with-pcre=../pcre –with-http_ssl_module –with-http_stub_status_module –with-openssl=../openssl –with-zlib=../zlib-1.2.8 –with-http_upstream_check_module –with-http_concat_module –with-syslog –with-backtrace_module –with-http_realip_module –add-module=../ngx_cache_purge –add-module=../ngx_http_accounting_module
3. 复制一下，进入到nginx的源码目录
4. patch -p1 < /path/to/nginx_tcp_proxy_module/tcp.patch   
5. ./configure –prefix=/usr/local/nginx –user=www –group=www –with-pcre=../pcre –with-http_ssl_module –with-http_stub_status_module –with-openssl=../openssl –with-zlib=../zlib-1.2.8 –with-http_upstream_check_module –with-http_concat_module –with-syslog –with-backtrace_module –with-http_realip_module –add-module=../ngx_cache_purge –add-module=../ngx_http_accounting_module –add-module=/path/to/nginx_tcp_proxy_module   
6. make   
7.  cp  objs/nginx /usr/local/nginx/sbin/nginx
8.   假定你有两个服务需要通过Nginx的Tcp（8888）端口进行负载均衡，参考如下配置：
   Shell代码  
   1. tcp {  
   2.   
   3.     upstream cluster {  
   4.         # simple round-robin  
   5.         server 192.168.0.1:80;  
   6.         server 192.168.0.2:80;  
   7.   
   8.         check interval=3000 rise=2 fall=5 timeout=1000 type=tcp;  
   9.   
   10.         #check interval=3000 rise=2 fall=5 timeout=1000 type=ssl_hello;  
   11.   
   12.         #check interval=3000 rise=2 fall=5 timeout=1000 type=http;  
   13.         #check_http_send “GET / HTTP/1.0 ”;  
   14.         #check_http_expect_alive http_2xx http_3xx;  
   15.     }  
   16.   
   17.     server {  
   18.         listen 8888; 
   19.         proxy_pass cluster;  
   20.     }  
   21. }  

   /usr/local/nginx/sbin/nginx -s reload

9. /tengine/conf/tcp_proxy/socket.xxx.com

10. nginx.conf增加一条include tcp_proxy/*;

12. cat socket.xxx.com 
13. tcp { 
14.     upstream socket_xxx_com { 
15.         server 1.1.1.1:8888;  
16.  
17.         check interval=3000 rise=2 fall=5 timeout=1000; #check interval=3000 rise=2 fall=5 timeout=1000 type=tcp;
18. }
19.  
20.     server { 
21.         listen 8888; 
22.         proxy_pass socket_xxx_com; 
23.     } 
24. }
