1、Linux 安装
不管是使用的Windows虚拟机环境该是ubuntu操作系统，咱们都是基于Linux环境的安装。具体操作步骤如下。
1.1、更新Nginx安装包
// 更新包sudo apt-get update
// 下载安装nginxsudo apt-get install nginx1.2、Ubuntu安装之后的文件结构大致为
所有的配置文件都在/etc/nginx下，并且每个虚拟主机已经安排在了/etc/nginx/sites-available下
程序文件在/usr/sbin/nginx
日志放在了/var/log/nginx中
并已经在/etc/init.d/下创建了启动脚本nginx
默认的虚拟主机的目录设置在了/var/www/nginx-default (有的版本 默认的虚拟主机的目录设置在了/var/www, 请参考/etc/nginx/sites-available里的配置)
其实从上面的根目录文件夹可以知道，Linux系统的配置文件一般放在/etc，日志一般放在/var/log，运行的程序一般放在/usr/sbin或者/usr/bin。当然，如果要更清楚Nginx的配置项放在什么地方，可以打开/etc/nginx/nginx.conf 然后通过这种方式安装的，会自动创建服务，会自动在/etc/init.d/nginx新建服务脚本，然后就可以使用一下命令来启动。还有一个好处，创建好的文件由于放在/usr/sbin目录下，所以能直接在终端中使用nginx命令而无需指定路径。
sudo service nginx {start|stop|restart|reload|force-reload|status|configtest|rotate|upgrade}脚本如下：

esac1.3、测试安装是否成功
在命令行中输入：
sudo nginx -t窗口显示：
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful安装成功，则在浏览器输入IP地址，如下图即为安装成功：
1.4、卸载
1.4.1、停止nginx服务
sudo service nginx stop1.4.2、删除nginx，-purge包括配置文件
sudo apt-get --purge remove nginx1.4.3、移除全部不使用的软件包
sudo apt-get autoremove1.4.4、罗列出与nginx相关的软件并删除
dpkg --get-selections|grep nginx
sudo apt-get --purge remove nginx
sudo apt-get --purge remove nginx-common
sudo apt-get --purge remove nginx-core1.4.5、查看nginx正在运行的进程，如果有就kill掉
ps -ef |grep nginx
sudo kill -9 XXX2、mac Docker安装
相比较于Linux安装，使用容器就比较快捷。在我的另一篇博客中我有详细描述使用docker安装Nginx，大家可以进行参考。传送门：https://blog.csdn.net/lly576403061/article/details/129419317?spm=1001.2014.3001.5502
