➜  desktop brew install nginx
Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

To have launchd start nginx now and restart at login:
  brew services start nginx
Or, if you don't want/need a background service you can just run:
  nginx
==> Summary
🍺  /usr/local/Cellar/nginx/1.12.0_1: 23 files, 1MB
➜  desktop which nginx
/usr/local/bin/nginx
➜  desktop sudo brew services start nginx

不过试了一下，不是超级用户登陆，而是普通用户登陆，并且监听的端口在1024以下的（例如把默认的8080端口改为了80端口），nginx 开机是启动不了。因此，要 nginx 开机启动的话，需要给予它管理员权限：
sudo chown root:wheel /usr/local/Cellar/nginx/1.2.6/sbin/nginx
sudo chmod u+s /usr/local/Cellar/nginx/1.2.6/sbin/nginx

vagrant up 开启端口报错

==> homestead-7: Checking if box ‘laravel/homestead’ is up to date…
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 27017 is already in use
on the host machine.

To fix this, modify your current project’s Vagrantfile to use another
port. Example, where ‘1234’ would be replaced by a unique host port:

config.vm.network :forwarded_port, guest: 27017, host: 1234

Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn’t allow modifying port forwarding. You could
try ‘vagrant reload’ (equivalent of running a halt followed by an up)
so vagrant can attempt to auto-correct this upon booting. Be warned
that any unsaved work might be lost.
➜ Homestead git:(master) ✗ sudo lsof -n -i4TCP:27017 | grep LISTEN
mongod 526 huixisheng 11u IPv4 0x40824e155718bce3 0t0 TCP 127.0.0.1:27017 (LISTEN)

原因homestead和mongod的端口冲突了
