centos7下搭建ffmpeg+nginx

今天研究了在centos7下搭建ffmpeg和nginx 做一个备忘


ffmpeg官方搭建引导

https://trac.ffmpeg.org/wiki/CompilationGuide/Centos

Get the Dependencies

Get the dependencies. These are required for compiling, but you can remove them when you are done if you prefer (except make; it should be installed by default and many things depend on it).

# yum install autoconf automake bzip2 cmake freetype-devel gcc gcc-c++ git libtool make mercurial pkgconfig zlib-devel

In your home directory make a new directory to put all of the source code into:

mkdir ~/ffmpeg_sources

Compilation & Installation

Tip: If you do not require certain encoders you may skip the relevant section and then remove the appropriate ./configure option in FFmpeg. For example, if libvorbis is not needed, then skip that section and then remove –enable-libvorbis from the Install FFmpeg section.

NASM

An assembler used by some libraries. Highly recommended or your resulting build may be very slow.

cd ~/ffmpeg_sources
curl -O -L http://www.nasm.us/pub/nasm/releasebuilds/2.13.02/nasm-2.13.02.tar.bz2
tar xjvf nasm-2.13.02.tar.bz2
cd nasm-2.13.02
./autogen.sh
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install

Yasm

An assembler used by some libraries. Highly recommended or your resulting build may be very slow.

cd ~/ffmpeg_sources
curl -O -L http://www.nasm.us/pub/nasm/releasebuilds/2.13.02/nasm-2.13.02.tar.bz2
tar xjvf nasm-2.13.02.tar.bz2
cd nasm-2.13.02
./autogen.sh
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install

Yasm

An assembler used by some libraries. Highly recommended or your resulting build may be very slow.

cd ~/ffmpeg_sources
curl -O -L http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xzvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install

libx264

H.264 video encoder. See the H.264 Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with –enable-gpl –enable-libx264.

cd ~/ffmpeg_sources
git clone --depth 1 http://git.videolan.org/git/x264
cd x264
PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --enable-static
make
make install

Warning: If you get Found no assembler. Minimum version is nasm-2.13 or similar after running ./configure then the outdated nasm package from the repo is installed. Run yum remove nasm && hash -r and x264 will then use your newly compiled nasm instead. Ensure environment is able to resolve path to nasm binary.

libx265

H.265/HEVC video encoder. See the H.265 Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with –enable-gpl –enable-libx265.

cd ~/ffmpeg_sources
hg clone https://bitbucket.org/multicoreware/x265
cd ~/ffmpeg_sources/x265/build/linux
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="$HOME/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source
make
make install

libfdk_aac

MP3 audio encoder.

Requires ffmpeg to be configured with –enable-libmp3lame.

cd ~/ffmpeg_sources
curl -O -L http://downloads.sourceforge.net/project/lame/lame/3.100/lame-3.100.tar.gz
tar xzvf lame-3.100.tar.gz
cd lame-3.100
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin" --disable-shared --enable-nasm
make
make install

libopus

Opus audio decoder and encoder.

Requires ffmpeg to be configured with –enable-libopus.

cd ~/ffmpeg_sources
curl -O -L https://archive.mozilla.org/pub/opus/opus-1.2.1.tar.gz
tar xzvf opus-1.2.1.tar.gz
cd opus-1.2.1
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install

libogg

Ogg bitstream library. Required by libtheora and libvorbis.

cd ~/ffmpeg_sources
curl -O -L http://downloads.xiph.org/releases/ogg/libogg-1.3.3.tar.gz
tar xzvf libogg-1.3.3.tar.gz
cd libogg-1.3.3
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install

libvorbis

Vorbis audio encoder. Requires libogg.

Requires ffmpeg to be configured with –enable-libvorbis.

cd ~/ffmpeg_sources
curl -O -L http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.5.tar.gz
tar xzvf libvorbis-1.3.5.tar.gz
cd libvorbis-1.3.5
./configure --prefix="$HOME/ffmpeg_build" --with-ogg="$HOME/ffmpeg_build" --disable-shared
make
make install

libvpx

VP8/VP9 video encoder and decoder. See the VP9 Video Encoding Guide for more information and usage examples.

Requires ffmpeg to be configured with –enable-libvpx.

cd ~/ffmpeg_sources
git clone --depth 1 https://chromium.googlesource.com/webm/libvpx.git
cd libvpx
./configure --prefix="$HOME/ffmpeg_build" --disable-examples --disable-unit-tests --enable-vp9-highbitdepth --as=yasm
make
make install

FFmpeg

cd ~/ffmpeg_sources
curl -O -L https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \
  --prefix="$HOME/ffmpeg_build" \
  --pkg-config-flags="--static" \
  --extra-cflags="-I$HOME/ffmpeg_build/include" \
  --extra-ldflags="-L$HOME/ffmpeg_build/lib" \
  --extra-libs=-lpthread \
  --extra-libs=-lm \
  --bindir="$HOME/bin" \
  --enable-gpl \
  --enable-libfdk_aac \
  --enable-libfreetype \
  --enable-libmp3lame \
  --enable-libopus \
  --enable-libvorbis \
  --enable-libvpx \
  --enable-libx264 \
  --enable-libx265 \
  --enable-nonfree
make
make install
hash -r

Compilation is now complete and ffmpeg (also ffprobe, ffserver, lame, and x264) should now be ready to use. The rest of this guide shows how to update or remove FFmpeg.

Tip: Keep the ffmpeg_sources directory and all contents if you intend to update as shown below. Otherwise you can delete this directory.


nginx搭建引导(来自linux公社)

https://www.linuxidc.com/Linux/2016-09/134907.htm
一. gcc 安装

yum install gcc-c++

二. PCRE pcre-devel 安装

yum install -y pcre pcre-devel

三. zlib 安装

yum install -y zlib zlib-devel

四. OpenSSL 安装

yum install -y openssl openssl-devel

官网下载

1.直接下载.tar.gz安装包,地址:https://nginx.org/en/download.html

2.使用wget命令下载(推荐)。

wget -c https://nginx.org/download/nginx-1.10.1.tar.gz

解压

依然是直接命令:

tar -zxvf nginx-1.10.1.tar.gz
cd nginx-1.10.1

配置

1.使用默认配置

./configure

2.自定义配置(不推荐)

./configure \
--prefix=/usr/local/nginx \
--conf-path=/usr/local/nginx/conf/nginx.conf \
--pid-path=/usr/local/nginx/conf/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--with-http_gzip_static_module \
--http-client-body-temp-path=/var/temp/nginx/client \
--http-proxy-temp-path=/var/temp/nginx/proxy \
--http-fastcgi-temp-path=/var/temp/nginx/fastcgi \
--http-uwsgi-temp-path=/var/temp/nginx/uwsgi \
--http-scgi-temp-path=/var/temp/nginx/scgi

注:将临时文件目录指定为/var/temp/nginx,需要在/var下创建temp及nginx目录

编译安装

make
make install

查找安装路径:

whereis nginx

启动、停止nginx

cd /usr/local/nginx/sbin/
./nginx 
./nginx -s stop
./nginx -s quit
./nginx -s reload

./nginx -s quit:此方式停止步骤是待nginx进程处理任务完毕进行停止。
./nginx -s stop:此方式相当于先查出nginx进程id再使用kill命令强制杀掉进程。

查询nginx进程:

ps aux|grep nginx

重启 nginx

1.先停止再启动(推荐):
对 nginx 进行重启相当于先停止再启动,即先执行停止命令再执行启动命令。如下:

./nginx -s quit
./nginx

2.重新加载配置文件:
当 ngin x的配置文件 nginx.conf 修改后,要想让配置生效需要重启 nginx,使用-s reload不用先停止 ngin x再启动 nginx 即可将配置信息在 nginx 中生效,如下:

./nginx -s reload

启动成功后,在浏览器可以看到这样的页面:

附件:两个配置文件

nginx.conf
mime.types
