安装nginx

[root@proxy ~]# yum –y install gcc pcre-devel openssl-devel        //安装依赖包
[root@proxy ~]# tar  -xf   nginx-1.12.2.tar.gz
[root@proxy ~]# cd  nginx-1.12.2
[root@proxy nginx-1.12.2]# ./configure   
> --with-http_ssl_module                                //开启SSL加密功能
> --with-stream                                       //开启4层反向代理功能
[root@proxy nginx-1.12.2]# make && make install           //编译并安装

配置

[root@proxy ~]# vim /usr/local/nginx/conf/nginx.conf
stream {
            upstream backend {
               server 192.168.2.100:22;            //后端SSH服务器的IP和端口
               server 192.168.2.200:22;
}
            server {
                listen 12345;                    //Nginx监听的端口
                proxy_connect_timeout 1s;
                proxy_timeout 3s;
                 proxy_pass backend;
             }
