Mac搭建nginx+rtmp服务器
记录下安装rtmp的过程
一、安装Homebrew
确认已经安装了Homebrew，可以通过brew -v查看版本的方式查看是否已经安装过，这个不用过多解释。
~ brew -v
Homebrew 2.1.15
Homebrew/homebrew-core (git revision fcd3; last commit 2019-10-31)
如果没有安装，可以通过下面命令安装：
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
自然卸载命令：
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
如果无法安装，也可以尝试下下面的方法：
/bin/bash -c "$(curl -fsSL https://cdn.jsdelivr.net/gh/Homebrew/install@HEAD/install.sh)"
二、安装nginx
安装过程我也是网上查来的，如果可以正常的安装，我也就不写这篇笔记了，首先安装您可能搜到的步骤进行安装：
brew tap homebrew/nginx
结果我遇到了下面的报错：
Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).
==> Updated Formulae
abyss docker2aci libhttpseverywhere subversion
amqp-cpp emscripten mypy tup
chronograf grpc packmol znapzend
dnscrypt-proxy influxdb rancher-cli
Error: homebrew/nginx was deprecated. This tap is now empty as all its formulae were migrated.
最终在这篇博客找到了原因，根查原因是因为homebrew/nginx的git路径变了。因此需要使用denji/nginx命令来解决这个问题。
通过下面的命令再试试：
~ brew tap denji/nginx
Updating Homebrew...
==> Tapping denji/nginx
Cloning into '/usr/local/Homebrew/Library/Taps/denji/homebrew-nginx'...
remote: Counting objects: 72, done.
remote: Compressing objects: 100% (72/72), done.
remote: Total 72 (delta 1), reused 28 (delta 0), pack-reused 0
Unpacking objects: 100% (72/72), done.
Tapped 62 formulae (162 files, 130.2KB)
到此，继续执行下面的命令：
~ brew install nginx-full --with-rtmp-module
==> Installing nginx-full from denji/nginx
Error: Cannot install denji/nginx/nginx-full because conflicting formulae are installed.
nginx: because nginx-full symlink with the name for compatibility with nginx
Please `brew unlink nginx` before continuing.
Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.
还是会报错，仔细看错误提示需要“brew unlink nginx”。那么我们先执行再说：
~ brew unlink nginx
接下来配置config，在 /usr/local/etc/nginx 下的nginx.conf
rtmp {
server {
listen 1935;
ping 30s;
notify_method get;
application myapp {
live on;
record off;
max_connections 1024;
}
#增加对HLS支持开始
application hls {
live on;
hls on;
hls_path /usr/local/var/www/hls;
hls_fragment 5s;
}
#增加对HLS支持结束
}
}
三、启动nginx
到此结束，我们启动下nginx：
~ nginx
或者是重启：
~ nginx -s reload
浏览器访问下：http://localhost:8080，看结果是否如下图呢：

那么 安装过程到此完成了。
如果遇到端口被占用的问题，可以自己搜索下解决，目前安装过程就到此为止了。
