Nginx流媒體支援配置

Nginx是一個短小精悍，且效能超強的Web伺服器，同時也可以用作反向 Proxy伺服器以及郵件伺服器。除此之外Nginx也可以用於搭建一個簡易的流媒體伺服器。基於此，本文描述了在Nginx 1.8之上構建一個簡易的流媒體伺服器，同時通過反向 Proxy的方式將其代理至流媒體伺服器。

1、當前的運行環境# more /etc/redhat-release CentOS release 6.5 (Final)# /u01/app/nginx/sbin/nginx -vnginx version: nginx/1.8.12、安裝檔案下載http://download.csdn.net/detail/robinson_0612/97389483、安裝檔案位置# pwd/u01/soft# lsyamdi-1.9.tar.gz      nginx_mod_h264_streaming-2.2.7.tar.gz      nginx-1.8.1

二、安裝及重新編譯Nginx

1、安裝yamdi# tar -xf yamdi-1.9.tar.gz # cd yamdi-1.9# make && make install        gcc -O2 -Wall yamdi.c -o yamdi        install -m 0755 -o root yamdi /usr/local/bin2、安裝nginx_mod_h264_streaming# cd /u01/soft# tar -xf nginx_mod_h264_streaming-2.2.7.tar.gz # vim /u01/soft/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c###注釋掉158-161行    157   /* TODO: Win32 */    158 /*  if (r->zero_in_uri)    159   {    160     return NGX_DECLINED;    161   }    162 */      ###否則出現如下錯誤# make In file included from /usr/local/src/nginx_mod_h264_streaming-2.2.7/src/ngx_http_h264_streaming_module.c:2:/usr/local/src/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c: 在函數‘ngx_streaming_handler’中:/usr/local/src/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c:158: 錯誤：‘ngx_http_request_t’沒有名為‘zero_in_uri’的成員make[1]: *** [objs/addon/src/ngx_http_h264_streaming_module.o] 錯誤 1make[1]: Leaving directory `/usr/local/src/nginx-1.8.1'make: *** [build] 錯誤 23、查看nginx當前已編譯的模組以及添加模組# /u01/app/nginx/sbin/nginx -Vnginx version: nginx/1.8.1built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) built with OpenSSL 1.0.1e-fips 11 Feb 2013TLS SNI support enabledconfigure arguments:         --prefix=/u01/app/nginx --sbin-path=/u01/app/nginx/sbin/nginx --conf-path=/u01/app/nginx/conf/nginx.conf         --error-log-path=/u01/app/nginx/logs/error.log --http-log-path=/u01/app/nginx/logs/access.log                              --pid-path=/u01/app/nginx/nginx.pid --lock-path=/u01/app/nginx/nginx.lock         --http-client-body-temp-path=/u01/app/nginx/tempcache/client_temp         --http-proxy-temp-path=/u01/app/nginx/tempcache/proxy_temp         --http-fastcgi-temp-path=/u01/app/nginx/tempcache/fastcgi_temp         --http-uwsgi-temp-path=/u01/app/nginx/tempcache/uwsgi_temp         --http-scgi-temp-path=/u01/app/nginx/tempcache/scgi_temp --user=nginx --group=nginx         --with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module         --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module         --with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module         --with-http_stub_status_module --with-http_auth_request_module --with-mail --with-mail_ssl_module         --with-file-aio --with-http_spdy_module --with-ipv6###將nginx_mod_h264_streaming模組添加到nginx      # cd /u01/soft/nginx-1.8.1# ./configure  \--prefix=/u01/app/nginx --sbin-path=/u01/app/nginx/sbin/nginx                                                \--conf-path=/u01/app/nginx/conf/nginx.conf --error-log-path=/u01/app/nginx/logs/error.log                         \--http-log-path=/u01/app/nginx/logs/access.log --pid-path=/u01/app/nginx/nginx.pid                                \      --lock-path=/u01/app/nginx/nginx.lock --http-client-body-temp-path=/u01/app/nginx/tempcache/client_temp      \--http-proxy-temp-path=/u01/app/nginx/tempcache/proxy_temp                                                   \--http-fastcgi-temp-path=/u01/app/nginx/tempcache/fastcgi_temp                                               \--http-uwsgi-temp-path=/u01/app/nginx/tempcache/uwsgi_temp                                                   \--http-scgi-temp-path=/u01/app/nginx/tempcache/scgi_temp --user=nginx --group=nginx                          \--with-http_ssl_module --with-http_realip_module --with-http_addition_module --with-http_sub_module          \--with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module               \--with-http_gzip_static_module --with-http_random_index_module --with-http_secure_link_module                \--with-http_stub_status_module --with-http_auth_request_module --with-mail --with-mail_ssl_module            \--with-file-aio --with-http_spdy_module --with-ipv6                                                          \--add-module=/u01/soft/nginx_mod_h264_streaming-2.2.7      ###使用add-module添加模組# make# /u01/app/nginx/sbin/nginx -s stop# cp /u01/app/nginx/sbin/nginx /u01/app/nginx/sbin/nginx.bk.0116### 替換nginx 二進位檔案# cp /u01/soft/nginx-1.8.1/objs/nginx /u01/app/nginx/sbin/nginx# service nginx startStarting nginx:                                            [  OK  ]# /u01/app/nginx/sbin/nginx -Vnginx version: nginx/1.8.1built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) built with OpenSSL 1.0.1e-fips 11 Feb 2013TLS SNI support enabledconfigure arguments: --prefix=/u01/app/nginx      ................--add-module=/u01/soft/nginx_mod_h264_streaming-2.2.7

四、Nginx模組動態增加

NGINX 1.9.11開始增加載入動態模組支援，從此不再需要替換nginx檔案即可增加第三方擴充。目前官方只有幾個模組支援動態載入，第三方模組需要升級支援才可編譯成模組。# ./configure --help | grep dynamic  --with-http_xslt_module=dynamic            enable dynamic ngx_http_xslt_module  --with-http_image_filter_module=dynamic    enable dynamic ngx_http_image_filter_module  --with-http_geoip_module=dynamic           enable dynamic ngx_http_geoip_module  --with-mail=dynamic                        enable dynamic POP3/IMAP4/SMTP proxy module  --with-stream=dynamic                      enable dynamic TCP proxy module  --add-dynamic-module=PATH                  enable dynamic external module如上可看出官方支援5個動態模組編譯，需要增加第三方模組，使用參數--add-dynamic-module=即可。NGINX動態模組文法，此配置方法和Apache httpd大同小異        load_module        Default: —        配置段: main        說明：版本必須>=1.9.11        樣本：                load_module modules/ngx_mail_module.so;
