直播----Mac+Nginx+nginx-rtmp-module-1.2.1服务器搭建

kotlin vs java

下载nginx和nginx-rtmp-module

wget http://nginx.org/download/nginx-1.19.4.tar.gz
git clone https://github.91chifun.workers.dev//https://github.com/arut/nginx-rtmp-module.git (快速通道下载)

生成makefile编译文件

tar -zxvf nginx-1.19.4.tar.gz (解压)
cd nginx-1.19.4
./configure --prefix=/data/server/nginx --with-http_ssl_module --add-module=../nginx-rtmp-module

到这一步的时候碰到如下错误：（注意如果确实pcre,zlib的话，使用homebrew安装就可以了，安装后的目录系统会自动搜索到）

checking for OpenSSL library ... not found
checking for OpenSSL library in /usr/local/ ... not found 
checking for OpenSSL library in /usr/pkg/ ... not found
checking for OpenSSL library in /opt/local/ ... not found

./configure: error: SSL modules require the OpenSSL library.
You can either do not enable the modules, or install the OpenSSL library
into the system, or build the OpenSSL library statically from the source
with nginx by using --with-openssl= option.

原因有可能最后openssl没有安装到系统会自动搜索的那几个目录。我的mac上就不是。按照提示加上路径即可(注意/usr/local/Cellar/[email protected]/1.1.1h是你自己mac电脑上openssl的路径，如果没有安装OpenSSL，则先安装OpenSSL：)：

 brew install openssl

./configure --prefix=/Users/wangqi/ndk/nginx/nginx-1.19.4/bin --add-module=../nginx-rtmp-module-1.2.1/ --with-openssl=/usr/local/Cellar/[email protected]/1.1.1h

如果添加路径后编译成功：

Configuration summary
  + using system PCRE library
  + using OpenSSL library: /usr/local/Cellar/[email protected]/1.1.1h
  + using system zlib library

  nginx path prefix: "/Users/wangqi/ndk/nginx"
  nginx binary file: "/Users/wangqi/ndk/nginx/sbin/nginx"
  nginx modules path: "/Users/wangqi/ndk/nginx/modules"
  nginx configuration prefix: "/Users/wangqi/ndk/nginx/conf"
  nginx configuration file: "/Users/wangqi/ndk/nginx/conf/nginx.conf"
  nginx pid file: "/Users/wangqi/ndk/nginx/logs/nginx.pid"
  nginx error log file: "/Users/wangqi/ndk/nginx/logs/error.log"
  nginx http access log file: "/Users/wangqi/ndk/nginx/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp

编译成功执行make && make install

可能出现如下错误：

 /Library/Developer/CommandLineTools/usr/bin/make -f objs/Makefile
cd /usr/local/opt/[email protected] \
&& if [ -f Makefile ]; then /Library/Developer/CommandLineTools/usr/bin/make clean; fi \
&& ./config --prefix=/usr/local/opt/[email protected]/.openssl no-shared no-threads  \
&& /Library/Developer/CommandLineTools/usr/bin/make \
&& /Library/Developer/CommandLineTools/usr/bin/make install_sw LIBDIR=lib
/bin/sh: ./config: No such file or directory
make[1]: *** [/usr/local/opt/[email protected]/.openssl/include/openssl/ssl.h] Error 127
make: *** [build] Error 2

则需要修改当前目录下auto/lib/openssl/conf文件，执行vim auto/lib/openssl/conf打开文件，替换以下代码：

CORE_INCS="$CORE_INCS $OPENSSL/.openssl/include"
CORE_DEPS="$CORE_DEPS $OPENSSL/.openssl/include/openssl/ssl.h"
CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libssl.a"
CORE_LIBS="$CORE_LIBS $OPENSSL/.openssl/lib/libcrypto.a"

替换成（其实就是去掉了一层路径）：

CORE_INCS="$CORE_INCS $OPENSSL/include"
CORE_DEPS="$CORE_DEPS $OPENSSL/include/openssl/ssl.h"
CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libssl.a"
CORE_LIBS="$CORE_LIBS $OPENSSL/lib/libcrypto.a"

注意：修改完之后需要重新执行一遍 configure，否则修改不生效,如下：

./configure --prefix=/Users/wangqi/ndk/nginx/nginx-1.19.4/bin --add-module=../nginx-rtmp-module-1.2.1/ --with-openssl=/usr/local/Cellar/[email protected]/1.1.1h

make && make install

上面重新执行代码也可以直接执行：nginx -s reload

执行完成后就会在当前目录下生成一个bin文件夹，里面包含了我们编译成功生成的文件,如下四个文件夹：

conf  logs  html  sbin

配置nginx.conf文件:

#进入目录
cd bin/conf/
#打开文件
vim nginx.conf

  
  #user  nobody;
  worker_processes  1;
  
  #error_log  logs/error.log;
  #error_log  logs/error.log  notice;
  #error_log  logs/error.log  info;
  
  #pid        logs/nginx.pid;
 
 
 events {
     #最多支持高并发的数量，最多1024个人观看，可以调整
     worker_connections  1024;
 }
   #rtmp协议
 rtmp {
     server {
          #默认端口
         listen 1935;
          #直播应用名称（自定义）
         application myapp{
             live on;  #代表打开直播
             drop_idle_publisher 5s;#丢弃空闲的发布者，如果连接服务器超过5s则丢弃掉。（因为并发数量很宝贵）
         }
     }
 }
 #代表支持http协议
 http {
     server {
         listen      8081;#服务监听端口
           #以下是分发路径，比如你本地访问http://localhost:8081/stat，则指向下面路径
         location /stat { 
             rtmp_stat all;
             rtmp_stat_stylesheet stat.xsl;
         }
            #http://localhost:8081/stat.xsl
         location /stat.xsl {
             root /Users/wangqi/ndk/nginx/nginx-rtmp-module-1.2.1/;
         }
            #http://localhost:8081/control
         location /control {
             rtmp_control all;
         }
           #http://localhost:8081/rtmp-publisher
         location /rtmp-publisher {
             root /Users/wangqi/ndk/nginx/nginx-rtmp-module-1.2.1/test;
         }
           #http://localhost:8081/
         location / {
             root /Users/wangqi/ndk/nginx/nginx-rtmp-module-1.2.1/test/www;
         }
     }
 }

保存文件，回到nginx-1.19.4目录下，执行.bin/sbin/nginx，其实就是执行我们bin->sbin目录下的nginx文件。
可能报错提示端口被占用（1935和8081端口）

#运行以下，查看占用这两个的进程
sudo lsof -i:1935
sudo lsof -i:8081

#查看占用进程

成功截图

1. 使用第三方软件拉流测试。VLC

1.1: 下载成功安装

安装成功配置拉流地址展示

添加成功，右键点击播放

推流测试:

ffmpeg -re -i 你的视频文件的绝对路径(如/Users/wangqi/ndk/nginx/video.mp4) -vcodec copy -f flv rtmp://localhost:1935/myapp/room(1935是我们上面rtmp的默认进程号，myapp就是我们上面自定义的application名字，room代表房间可随便写，注意这是本地一个rtmp协议)
// 如：ffmpeg -re -i /Users/wangqi/ndk/nginx/video.mp4 -vcodec copy -f flv rtmp://localhost:1935/myapp/room

推流过程

最终效果图，可以看到上面有我们拉流的地址

拉流准备播放完成，在推流过程中就会弹出推流的视频。顺序是先准备拉流，再推。以上是把本地的视频文件推流到服务器然后利用VLC进行播放；
