MAC 上編譯安裝nginx-rtmp-module 流媒體服務器

記錄踩坑過程

下載nginx和nginx-rtmp-module

wget http://nginx.org/download/nginx-1.15.3.tar.gz
git clone https://github.com/arut/nginx-rtmp-module

生成makefile

tar -zxvf nginx-1.15.3.tar.gz
cd nginx-1.15.3
./configure --prefix=/data/server/nginx --with-http_ssl_module --add-module=../nginx-rtmp-module

報如下錯誤：

checking for PCRE library ... not found
checking for PCRE library in /usr/local/ ... not found
checking for PCRE library in /usr/include/pcre/ ... not found
checking for PCRE library in /usr/pkg/ ... not found
checking for PCRE library in /opt/local/ ... not found

去掉http_rewrite模塊：

./configure --prefix=/usr/local/nginx --with-http_ssl_module --add-module=../nginx-rtmp-module --without-http_rewrite_module

到這一步的時候碰到如下錯誤：

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.

執行一下openssl,看是否openssl已經安裝。

openssl

如果沒有安裝，執行下面的命令進行安裝：

 brew install openssl

有可能最后openssl沒有安裝到系統會自動搜索的那幾個目錄。我的mac上就不是。查找openssl 安裝目錄：

brew info openssl

按照提示加上路徑即可：

./configure --prefix=/Users/username/nginx --with-http_ssl_module --add-module=../nginx-rtmp-module --with-openssl=/usr/local/opt/openssl@1.1

成功后出現如下提示：

  + using OpenSSL library: /usr/local/opt/openssl@1.1
  + using system zlib library

make

執行make生成二進制文件：

 make

報如下錯誤：

 /Library/Developer/CommandLineTools/usr/bin/make -f objs/Makefile
cd /usr/local/opt/openssl@1.1 \
&& if [ -f Makefile ]; then /Library/Developer/CommandLineTools/usr/bin/make clean; fi \
&& ./config --prefix=/usr/local/opt/openssl@1.1/.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/openssl@1.1/.openssl/include/openssl/ssl.h] Error 127
make: *** [build] Error 2

執行如下的命令，修改一個文件

vim auto/lib/openssl/conf

把下面的幾行中的.openssl去掉，然后保存

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

改成

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

注意：修改完之后需要重新執行一遍 configure，否則修改不生效。

再次make成功

make install

執行make install 安裝nginx和nginx-rtmp-module到指定目錄：

make install

修改配置文件

修改安裝目錄下面的conf/nginx.conf文件，添加rtmp配置：

rtmp {
    server {
        listen 1935;

        application mytv {
            live on;
        }
    }
}

啟動服務

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

使用ffmpeg推流

ffmpeg -re -i /Users/username/test_sps_1.mp4 -vcodec libx264 -acodec aac -f flv rtmp://localhost:1935/mytv/home

ffplay 播放

ffplay -i. rtmp://localhost:1935/mytv/home

打印debug日志

如果需要調試查看debug log,做下面兩部操作：

添加--with-debug選項

  ./configure --prefix=/Users/username/nginx --with-http_ssl_module --add-module=../nginx-rtmp-module --with-debug --with-openssl=/usr/local/opt/openssl@1.1

修改配置文件nginx.conf中的日志配置項：

#error_log  logs/error.log  info;

修改為

 error_log  logs/error.log  debug;
