之前寫過：

最近工作辦公電腦換了 Mac，剛好有機會實踐一下。

安裝非常簡單：

sudo port install nginx

sudo brew install nginx

brew search nginx

安裝完成會輸出以下提示：我是使用 port 安裝的：

nginx has the following notes:
    A set of sample configuration files has been installed in /opt/local/share/nginx/examples.
    
    Additionally, the files nginx.conf, mime.types, fastcgi.conf have been copied to /opt/local/etc/nginx if they didn't
    exist yet.
    Adjust these files to your needs before starting nginx.
 

which nginx
/opt/local/sbin/nginx

/opt/local/share/nginx/examples 目錄下是配置示例檔案；

/opt/local/etc/nginx 實際使用的配置檔案 在這個目錄下；

編輯配置&重新載入配置：

sudo vi nginx.conf 
sudo nginx -s reload

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

events {
    worker_connections  1024;
}

    default_type  application/octet-stream;

    #access_log  logs/access.log  main;

    sendfile        on;

    server {

        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            root   share/nginx/html;
            index  default.htm index.html index.htm;
        }

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   share/nginx/html;
 

}

    }


    # another virtual host using mix of IP-, name-, and port-based configuration

    #    server_name  somename  alias  another.alias;

    #    location / {

    #        index  index.html index.htm;
    #    }
    #}
}
 

常用命令

nginx  啟動，可能需要許可權，使用 sudo nginx

nginx -V 檢視Nginx的版本號

大V顯示的是非常詳細的資訊，小v只顯示第一行：

nginx version: nginx/1.11.10
built with OpenSSL 1.0.2k  26 Jan 2017
TLS SNI support enabled
configure arguments: --prefix=/opt/local --with-cc-opt='-I/opt/local/include -Os' --with-ld-opt='-L/opt/local/lib -Wl,-headerpad_max_install_names' --conf-path=/opt/local/etc/nginx/nginx.conf --error-log-path=/opt/local/var/log/nginx/error.log --http-log-path=/opt/local/var/log/nginx/access.log --pid-path=/opt/local/var/run/nginx/nginx.pid --lock-path=/opt/local/var/run/nginx/nginx.lock --http-client-body-temp-path=/opt/local/var/run/nginx/client_body_temp --http-proxy-temp-path=/opt/local/var/run/nginx/proxy_temp --http-fastcgi-temp-path=/opt/local/var/run/nginx/fastcgi_temp --http-uwsgi-temp-path=/opt/local/var/run/nginx/uwsgi_temp --with-ipv6 --with-http_flv_module --with-http_mp4_module --with-http_secure_link_module --with-http_ssl_module

nginx -s quit 正常停止或關閉Nginx

nginx -s stop 快速停止或關閉Nginx

nginx -s reload 重新載入配置檔案

nginx -t 測試nginx.conf配置檔案是否正確

nginx -s stop 和 -s quit 有什麼區別呢？

quit 是一種優雅的退出方式。優雅在哪裡呢？

Quit is a graceful shutdown. Nginx finishes serving the open connections before shutdown

Stop is a quick shutdown where is terminates in between serving the connection

當nginx收到quit訊號後，首先停止接受連線，不再接受新的連線請求了；然後程序如果還在服務中（也就是還有訪問請求沒有處理並響應完成），那麼就不會關閉該程序，直到程序完成服務為止。當所有未完成的請求都處理完成了，再退出。

而接收到 Stop 訊號後就不管那麼多了，直接退出程序。

quit 就好比到下班時間了，手頭還有點工作沒做完，做完了再走；stop 是下班就走。
