brew下安装并且使用nginx

使用 brew search nginx命令，搜索nginx

使用 brew install nginx命令，安装nginx

使用 nginx -v 查看ngxin版本：

nginx version: nginx/1.15.11

使用 brew info nginx 查看nginx的详细信息（我们需要知道配置文件的路径）

nginx: stable 1.15.11 (bottled), HEAD
HTTP(S) server and reverse proxy, and IMAP/POP3 proxy server
https://nginx.org/
/usr/local/Cellar/nginx/1.15.11 (25 files, 2MB) *

==> Dependencies
Required: openssl ✔, pcre ✔
==> Options
--HEAD
    Install HEAD version
==> Caveats
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

install: 39,863 (30 days), 101,681 (90 days), 432,120 (365 days)
install_on_request: 37,388 (30 days), 95,854 (90 days), 395,442 (365 days)
build_error: 0 (30 days)

由以上信息我们知道nginx的配置文件的路径在/usr/local/etc/nginx/nginx.conf，默认端口为8080

因为Tomcat默认端口也为8080，同时也避免被骇客攻击，修改端口也是很有必要的。

我们使用vim编辑器来修改默认端口，终端输入 vim /usr/local/etc/nginx/nginx.conf 编辑默认端口。

   server {
 36         listen       8087;
 37         server_name  localhost;
 38         charset utf-8;
 39         #charset koi8-r;

使用 brew services start nginx 命令启动nginx
