先下載nginx_tcp_proxy_module模塊。

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

2. 先看看自己原來nginx安裝有哪些模塊（編譯參數）：

   [[email protected]]# /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. 復制一下，進入到nginx的源碼目錄
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. 假定你有兩個服務需要通過Nginx的Tcp（8888）端口進行負載均衡，參考如下配置：
   Shell代碼
   1. tcp {
   3. upstream cluster {
   4. # simple round-robin
   5. server 192.168.0.1:80;
   6. server 192.168.0.2:80;
   8. check interval=3000 rise=2 fall=5 timeout=1000 type=tcp;
   10. #check interval=3000 rise=2 fall=5 timeout=1000 type=ssl_hello;
   12. #check interval=3000 rise=2 fall=5 timeout=1000 type=http;
   13. #check_http_send “GET / HTTP/1.0\r\n\r\n”;
   14. #check_http_expect_alive http_2xx http_3xx;
   15. }
   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增加一條include tcp_proxy/*;

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

基於nginx和tengine的tcp反向代理，負載均衡 安裝和配置
