nginx-rtmp-moudle安装与配置

2016/06/23技术

Github：https://github.com/arut/nginx-rtmp-module
此项目很久没更新了，不过基本使用没什么问题，亲测nginx1.10.1上会有一点小bug
这里再给一个fork后近期有过更新的项目 https://github.com/sergey-dryabzhinsky/nginx-rtmp-module

1.安装依赖包

1
2
3

yum install -y gcc gcc-c++
yum install -y openssl-devel pcre-devel zlib-devel
yum install git

由于之前将yum源全部删除只保留了系统更新的北理源，这里最好连外网安装一下EPEL便于一些软件的安装，校内源有提供

1	yum install epel-release

这里涉及到使用shell登录校园网，可看博客里的shell登录校园网

2.与nginx一起安装编译

cd /usr/local/
wget http://nginx.org/download/nginx-1.10.1.tar.gz
tar -zvxf nginx-1.10.1.tar.gz
git clone git://github.com/sergey-dryabzhinsky/nginx-rtmp-module.git
git clone git://github.com/gnosek/nginx-upstream-fair.git
cd nginx-1.10.1
./configure --add-module=../nginx-rtmp-module --add-module=../nginx-upstream-fair --with-http_ssl_module
make
make install

ps.这里一起安装了一个之后负载均衡可能会用到的nginx-upstream-fair https://github.com/gnosek/nginx-upstream-fair

3.将nginx添加到服务

1 2	cd /etc/init.d/ vim nginx

5.设置权限，启动nginx

1
2
3

chmod 755 nginx
chkconfig --add nginx
service nginx start

6.为便于转码和多码率推流建议安装一下ffmpeg
由于yum官方源和EPEL都没有这货，只能另外添加一个源
