nginx使用stream实现透传

nginx配置如下：

 1 # For more information on configuration, see
 2 #   * Official English Documentation: http://nginx.org/en/docs/
 3 #   * Official Russian Documentation: http://nginx.org/ru/docs/
 4 user nginx;
 5 worker_processes auto;
 6 error_log /var/log/nginx/error.log;
 7 pid /run/nginx.pid;
 8 
 9 # Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
10 include /usr/share/nginx/modules/*.conf;
11 worker_rlimit_nofile 65535;
12 events {
13     use epoll;
14     worker_connections 51200;
15     multi_accept on;
16 }
17 
18 stream {
19     upstream ldap {
20         server 22.104.1.1:389;
21         server 22.104.1.2:389;
22         server 22.104.1.8:389;
23     }
24     server {
25         listen 8389;
26         proxy_pass ldap;
27     }
28 }

如果，nginx版本不支持stream，可修改nginx配置，在第一行添加如下内容：

load_module /usr/lib64/nginx/modules/ngx_stream_module.so
