在5G流行的今天流媒体，成为不少开发人员的必备功课，所以自己搭建流媒体服务器也是必须的，今天就以Mac环境为模板，从零开始搭建一个本地流媒体服务器。 首先需要安装 1.安装Homebrew 打开终端, 查看是否已经安装了Homebrew, 直接终端输入命令

man brew

2.如果Mac已经安装了, 会显示一些命令的帮助信息. 此时 输入Q退出即可, 直接进入第二步 如果尚未安装，执行

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

这里有时会提示我们只需要等待便可

Downloading Command Line Tools (macOS Mojave version 10.14) for Xcode

error: RPC failed; curl 56 LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 60
fatal: the remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core failed!
Failed during: /usr/local/bin/brew update --force

3.需要brew update一下

Error: homebrew/nginx was deprecated. This tap is now empty as all its formulae were migrated.

MacBook-Pro:~ jiayuan$ brew tap homebrew/nginx Error: homebrew/nginx was deprecated. This tap is now empty as all its formulae were migrated.

4.安装成功

HEAD is now at bcc5f042b Merge pull request #6143 from letmaik/letmaik/HOMEBREW_CURL_RETRIES Already up-to-date. ==> Installation successful!

5.安装之后先更新一下 brew update

6.这里会提示一个错误

To restore the stashed changes to /usr/local/Homebrew run: 'cd /usr/local/Homebrew && git stash pop' Usage: brew install [options] formula

Install formula.

formula is usually the name of the formula to install, but it can be specified in several different ways.

Unless HOMEBREW_NO_INSTALL_CLEANUP is set, brew cleanup will be run for the installed formulae or, every 30 days, for all formulae.

7.需要先安装nginx

brew install nginx

会提示更新xcode如果不需要刻意删除，然后会提示

8.这里会提示xcode更新的问题没有安装的会提示安装 ==> Installing nginx-full from denji/nginx Error: Your Xcode (10.1) is too outdated. Please update to Xcode 10.2.1 (or delete it). Xcode can be updated from the App Store.

如果版本过低的话需要先将系统更新至10.2以上，在更新xcode，没有安装也没事主要是使用里面的xcode command line tool，但是版本需要更新至10.2以上

brew unlink nginx 这里是链接一下nginx

更新之后再次安装rtmp

brew install nginx-full --with-rtmp-module

会提示这个错误，需要多尝试几下

curl: (7) Failed to connect to github.com port 443: Operation timed out
Error: An exception occurred within a child process:
DownloadError: Failed to download resource "rtmp-nginx-module--patch"
Download failed: https://github.com/sergey-dryabzhinsky/nginx-rtmp-module/compare/v1.1.7.10..504b9ee.diff

如果安装成功会出现下面这段提示
To have launchd start denji/nginx/nginx-full now and restart at login: brew services start denji/nginx/nginx-full Or, if you don't want/need a background service you can just run: nginx

然后配置一下nginx端口rtmp服务在配置文件中

# 文件路径:/usr/local/etc/nginx/nginx.conf
vim /usr/local/etc/nginx/nginx.conf

主要是添加以下内容

#配置 rtmp server
rtmp{
     server{
#指定服务器端口
            listen 1935;
            chunk_size 4000;
#指定流应用
            application live
            {
                    live on;
                    record off;
                    allow play all;
            }
    }
}

然后启动nginx，如果已经启动过则是

nginx -s -reload

安装FFmpeg

brew install ffmpeg

最后下载一个vlc进行屏幕录制，然后使用第三方播放器就行测试（我这里使用的是腾讯的）
