nginx tcp模塊安裝

nginx tcp模塊安裝

• nginx版本 選擇版本
• tcp_model https://github.com/yaoweibin/nginx_tcp_proxy_module

初始 nginx 1.12 版本安裝

• 需要安裝OpenSSl

  • 有網絡：sudo apt-get install libssl-dev
  • 下載OpenSSl https://www.openssl.org/source/

• 安裝過程

  make 報錯

  ../libcrypto.a(eng_rsax.o): In function `e_rsax_bn_mod_exp':
  eng_rsax.c:(.text+0x132f): undefined reference to `mod_exp_512'
  ../libcrypto.a(eng_rsax.o): In function `e_rsax_rsa_mod_exp':
  eng_rsax.c:(.text+0x1c08): undefined reference to `mod_exp_512'
  eng_rsax.c:(.text+0x22a8): undefined reference to `mod_exp_512'

  e_rc4_hmac_md5.c:(.text+0x4f1): undefined reference to `rc4_md5_enc'
  

  解決方案 需配置 ./Configure linux-x86_64

  make install 報錯

  cms.pod around line 457: Expected text after =item, not a number
  cms.pod around line 461: Expected text after =item, not a number
  cms.pod around line 465: Expected text after =item, not a number
  cms.pod around line 470: Expected text after =item, not a number
  cms.pod around line 474: Expected text after =item, not a number
  

  make install_sw 解決錯誤。

• 安裝ngixn 1.12版本

  make過程報錯

  官網好多人遇到這個問題，沒找到解決辦法。。

安裝1.8版本的nginx

重新解壓 nginx_tcp_proxy_module-master

sudo patch -p1 < /home/guo/Downloads/nginx_tcp_proxy_module-master/tcp_1_8.patch 

sudo ./configure --add-module=/home/guo/Downloads/nginx_tcp_proxy_module-master --without-http_rewrite_module --with-openssl=/home/guo/Downloads/openssl-1.0.1f --without-http_gzip_module

Make 過程報錯

cms.pod around line 457: Expected text after =item, not a number
cms.pod around line 461: Expected text after =item, not a number
cms.pod around line 465: Expected text after =item, not a number
cms.pod around line 470: Expected text after =item, not a number
cms.pod around line 474: Expected text after =item, not a number

原因是nginx 調用了openssl的man包，而我們安裝openssl的過程中用的是make install_sw 命令，沒有安裝man包。報錯。

https://askubuntu.com/questions/454575/error-255-when-trying-to-install-openssl-1-0-1g-from-source

找到合適的openssl版本,重新安裝.

sudo patch -p1 < /home/guo/Downloads/nginx_tcp_proxy_module-master/tcp_1_8.patch 

sudo ./configure --add-module=/home/guo/Downloads/nginx_tcp_proxy_module-master --without-http_rewrite_module --with-openssl=/home/guo/Downloads/openssl-1.0.2g --without-http_gzip_module

搞定！！

nginx tcp 配置和測試

  tcp {

        upstream cluster {
            # simple round-robin
            server localhost:9200;
            #server 192.168.0.2:80;

            check interval=3000 rise=2 fall=5 timeout=1000;

            #check interval=3000 rise=2 fall=5 timeout=1000 type=ssl_hello;

            #check interval=3000 rise=2 fall=5 timeout=1000 type=http;
            #check_http_send "GET / HTTP/1.0\r\n\r\n";
            #check_http_expect_alive http_2xx http_3xx;
        }

        server {
            listen 8888;

            proxy_pass cluster;
        }
    }

通過9200端口可以訪問本地的ES系統：

curl -XGET 'localhost:9200/_cat/health?v&pretty'

正常訪問。

通過8888端口訪問本地的ES系統：

curl -XGET 'localhost:8888/_cat/health?v&pretty'

正常訪問。查看日誌文件，有一次端口轉發記錄。

其實從1.9版本開始，Nginx自帶Tcp反向代理處理模塊。

stream{
    upstream backend{                                          
        hash $remote_addr consistent;
        server 127.0.0.1:7397 max_fails=3 fail_timeout=10s;    
        server 127.0.0.1:7398 max_fails=3 fail_timeout=10s;
    }

    server{
        listen 1268 ssl;                                       
        ssl_certificate     /home/guogangj/certs/cert1268.pem; 
        ssl_certificate_key  /home/guogangj/certs/key1268.pem; 
        ssl_session_cache    shared:SSL:10m;                   
        ssl_session_timeout  10m;                              
        ssl_ciphers  HIGH:!aNULL:!MD5;                         
        ssl_prefer_server_ciphers  on;                         
        proxy_connect_timeout 20s;                             
        proxy_timeout 5m;                                      
        proxy_pass backend;                                    
    }
}
