[PHP知识库]01-nginx+rtmp 搭建

编译安装

1. 下载 nginx
2. 下载 rtmp 和 nginx 同一目录
3. 配置 --prefix指定输出路径

./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module

出现如下错误

checking for PCRE library ... found
checking for PCRE JIT support ... found
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=<path> option.

分析：需要 openssl 库支持

4. 下载 openssl 通过链接下载配置未成功，所以使用 brew安装

brew install openssl@1.1

5. 再次配置

需要安装 brew install pcre

./configure --prefix=/usr/local/nginx --add-module=../nginx-rtmp-module --with-openssl=/usr/local/Cellar/openssl@1.1 --with-pcre=/usr/local/Cellar/pcre/8.44

配置成功

  nginx binary file: "/usr/local/nginx/sbin/nginx"

  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"

6. 编译

make -j 16

7. 安装

make install

8. 查看是否安装成功

/usr/local/ 是否包含 nginx

9. 使用，cd /usr/local/nginx/

启动服务

sudo ./sbin/nginx -c ./conf/nginx.conf

关闭服务

sudo ./sbin/nginx -s stop

10. 配置 rtmp 到 nginx

vim /usr/local/nginx/conf/nginx.conf

增加如下文件到最后

rtmp {
    server {
        listen 1935; # 监听端口号
	chunk_size 4000;
# 应用名称 live 推流时需要使用
        application live {
            live on; # 开启实时
	    allow play all;
        }
    }
}

方式二：Mac上搭建直播服务器 Nginx+rtmp（暂未成功）

下载
brew tap denji/nginx 

安装

brew install nginx
brew install rtmp-module

or

brew install nginx --with-rtmp-module

brew reinstall rtmp-nginx-module

brew info nginx

启动ngxin 

服务器根目录：/usr/local/var/www
配置文件:/usr/local/etc/nginx/nginx.conf
全部文件 /usr/local/etc/nginx/servers/.

后台启动 brew services start nginx
nginx 

Run port 80:
 $ sudo chown root:wheel /usr/local/opt/nginx-full/bin/nginx
 $ sudo chmod u+s /usr/local/opt/nginx-full/bin/nginx
Reload config:
 $ nginx -s reload  ## 重新加载配置文件
Reopen Logfile:
 $ nginx -s reopen  ## 再次打开配置文件
Stop process:
 $ nginx -s stop    ## 停止服务器
Waiting on exit process
 $ nginx -s quit    ## 退出服务器

验证

需要使用 ffmpeg , 参考 [02-ffmpeg 安装](./02-ffmpeg 安装/index.md)

• 推流

ffmpeg -i ~/Desktop/D/download/071.flv -f flv rtmp://localhost/live/test

• 拉流

ffplay rtmp://localhost/live/test

推流可能失败

-f flv

推流失败
(主要原因：音频，视频分块了)
解决方案
-re (音视频保持原有速度播放)

清晰度不高

-f flv编码原因
解决方案
-c:v copy
