[原]Nginx流媒体支持配置
robinson_0612发表于 2017-01-16 17:04:46
Nginx是一个短小精悍，且性能超强的Web服务器，同时也可以用作反向代理服务器以及邮件服务器。除此之外Nginx也可以用于搭建一个简易的流媒体服务器。基于此，本文描述了在Nginx 1.8之上构建一个简易的流媒体服务器，同时通过反向代理的方式将其代理至流媒体服务器。
有关Nginx相关的基础知识
Linux 6下安装编译安装Nginx
Nginx 概述及日常管理
Nginx基于IP，端口，域名配置虚拟主机
Linux 下配置nginx到php的连接
一、当前的运行环境及安装文件
1、当前的运行环境
# more /etc/redhat-release
CentOS release 6.5 (Final)
# /u01/app/nginx/sbin/nginx -v
nginx version: nginx/1.8.1
2、安装文件下载
http://download.csdn.net/detail/robinson_0612/9738948
3、安装文件位置
# pwd
/u01/soft
# ls
yamdi-1.9.tar.gz nginx_mod_h264_streaming-2.2.7.tar.gz nginx-1.8.1二、安装及重新编译Nginx
1、安装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/bin
2、安装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
###注释掉158-161行
157 /* TODO: Win32 */
158 /* if (r->zero_in_uri)
159 {
160 return NGX_DECLINED;
161 }
162 */
###否则出现如下错误
# 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: 在函数‘ngx_streaming_handler’中:
/usr/local/src/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c:158: 错误：
‘ngx_http_request_t’没有名为‘zero_in_uri’的成员
make[1]: *** [objs/addon/src/ngx_http_h264_streaming_module.o] 错误 1
make[1]: Leaving directory `/usr/local/src/nginx-1.8.1'
make: *** [build] 错误 2
3、查看nginx当前已编译的模块以及添加模块

# make
# /u01/app/nginx/sbin/nginx -s stop
# cp /u01/app/nginx/sbin/nginx /u01/app/nginx/sbin/nginx.bk.0116
### 替换nginx 二进制文件
# cp /u01/soft/nginx-1.8.1/objs/nginx /u01/app/nginx/sbin/nginx
# service nginx start
Starting nginx: [ OK ]
# /u01/app/nginx/sbin/nginx -V
nginx version: nginx/1.8.1
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC)
built with OpenSSL 1.0.1e-fips 11 Feb 2013

configure arguments: --prefix=/u01/app/nginx

--add-module=/u01/soft/nginx_mod_h264_streaming-2.2.7三、Nginx配置文件摘录(供参考)

###反向代理端的配置
# /opt/nginx/sbin/nginx -v
nginx version: nginx/1.5.13
# more /opt/nginx/conf/conf.d/http-www.conf
upstream stream_srv {
server 10.24.249.21:9091 max_fails=3 fail_timeout=30s;
keepalive 32;
}
server {
listen 80;
server_name www.abc.com;
access_log /log/nginx/http-access.log;
error_log /log/nginx/http-error.log;
location /stream {
proxy_set_header Host $host;
proxy_set_header x-for $remote_addr;
proxy_set_header x-server $host;
proxy_set_header x-agent $http_user_agent;
proxy_pass http://stream_srv;
}
}
###测试
http://www.abc.com/stream/test.mp4四、Nginx模块动态增加
NGINX 1.9.11开始增加加载动态模块支持，从此不再需要替换nginx文件即可增加第三方扩展。
目前官方只有几个模块支持动态加载，第三方模块需要升级支持才可编译成模块。
# ./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
如上可看出官方支持5个动态模块编译，需要增加第三方模块，使用参数--add-dynamic-module=即可。
NGINX动态模块语法，此配置方法和Apache httpd大同小异
load_module
Default: —
配置段: main
说明：版本必须>=1.9.11
示例：
load_module modules/ngx_mail_module.so;
