MacOS 下 Nginx 安装记录

之前写过：

CentOS6.5下Nginx1.7.4安装记录

CentOS 6.5 下 Tengine 安装记录

最近工作办公电脑换了 Mac，刚好有机会实践一下。

安装非常简单：

sudo port install nginx

或者使用：

sudo brew install nginx

使用brew可能还需要：

brew search nginx

port 和 brew 是 Mac 下两大包管理工具，使用它们安装软件非常的方便，类似 CentOS下的 yum ，Ubuntu 下的 apt-get 。

安装完成会输出以下提示：我是使用 port 安装的：

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.

查看可执行文件 目录：

which nginx
/opt/local/sbin/nginx

/opt/local/share/nginx/examples 目录下是配置示例文件；

/opt/local/etc/nginx 实际使用的配置文件 在这个目录下；

编辑配置&重新加载配置：

sudo vi nginx.conf 
sudo nginx -s reload

配置文件 示例：我改了下端口和默认文档

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

        location = /50x.html {

	}

        #}
    }


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

    #server {

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

常用命令

nginx  启动，可能需要权限，使用 sudo nginx

nginx -V 查看Nginx的版本号

大V显示的是非常详细的信息，小v只显示第一行：

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 正常停止或关闭Nginx

nginx -s stop 快速停止或关闭Nginx

nginx -s reload 重新加载配置文件

nginx -t 测试nginx.conf配置文件是否正确

nginx -s stop 和 -s quit 有什么区别呢？

quit 是一种优雅的退出方式。优雅在哪里呢？

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

当nginx收到quit信号后，首先停止接受连接，不再接受新的连接请求了；然后进程如果还在服务中（也就是还有访问请求没有处理并响应完成），那么就不会关闭该进程，直到进程完成服务为止。当所有未完成的请求都处理完成了，再退出。

而接收到 Stop 信号后就不管那么多了，直接退出进程。

quit 就好比到下班时间了，手头还有点工作没做完，做完了再走；stop 是下班就走。
