nginx rtmp 服务搭建

环境：

centos7.4 64位

下载nginx和rtmp-module：

cd /home/yourname

wget http://nginx.org/download/nginx-1.15.8.tar.gz

tar xvf nginx-1.15.8.tar.gz

wget https://github.com/arut/nginx-rtmp-module/archive/master.zip

unzip master.zip

安装依赖：

yum install openssl-devel

编译：

cd nginx-1.15.8

./configure --add-module=../nginx-rtmp-module-master --prefix=/opt/nginx-install

make

make install

启动：

cd /opt/nginx-install/

vim conf/nginx.conf

修改一下端口

增加rtmp配置，参考https://github.com/arut/nginx-rtmp-module的文档，这个配置文件里有http 的配置，如果在nginx.conf上修改的花，可以只加上rtmp的配置。
