本文就简：
Step 1: Install Nginx
首先请保证你的apt源的完整性以及速度
Nginx is available in Ubuntu’s default repositories, so the installation is rather straight forward.（因为Nginx能够在Ubuntu的仓库中找到，所以安装过程就很直接了）
sudo apt-get update
sudo apt-get install nginx
Step 2: Adjust the Firewall
We can list the applications configurations that ufw knows how to work with by typing（键入以下命令就能得到一个应用列表，这个列表中的应用是ufw知道如何自配的）
sudo ufw app list
You should get a listing of the application profiles:
Output
Available applications:
Nginx Full
Nginx HTTP
Nginx HTTPS
OpenSSH
As you can see, there are three profiles available for Nginx（对于NGINX来说我们有三种模式可供选择）
Nginx Full: This profile opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic)
Nginx HTTP: This profile opens only port 80 (normal, unencrypted web traffic)
Nginx HTTPS: This profile opens only port 443 (TLS/SSL encrypted traffic)
You can enable this by typing:
sudo ufw allow 'Nginx HTTP'#或者选择Full也行
Step 3: Check your Web Server
e can check with the systemd init system to make sure the service is running by typing:
systemctl status nginx
lockey@ubuntu-lockey:~/.jupyter$ cat /var/www/html/index.html
<h1>gooooooooooooooooooood!</h1>
lockey@ubuntu-lockey:~/.jupyter$ curl localhost
<h1>gooooooooooooooooooood!</h1>
lockey@ubuntu-lockey:~/.jupyter$
Step 4: Manage the Nginx Process（管理NGINX程序）
To stop your web server, you can type:
sudo systemctl stop nginx
To start the web server when it is stopped, type:
sudo systemctl start nginx
To stop and then start the service again, type:
sudo systemctl restart nginx
If you are simply making configuration changes, Nginx can often reload without dropping connections. To do this, this command can be used:
sudo systemctl reload nginx
By default, Nginx is configured to start automatically when the server boots. If this is not what you want, you can disable this behavior by typing:
sudo systemctl disable nginx
To re-enable the service to start up at boot, you can type:
sudo systemctl enable nginx
Step 5: Get Familiar with Important Nginx Files and Directories（熟悉NGINX的重要配置文件以及网站目录）
Content（网站内容）
- /var/www/html: The actual web content, which by default only consists of the default Nginx page you saw earlier, is served out of the /var/www/html directory. This can be changed by altering Nginx configuration files.
Server Configuration（服务器配置）
- /etc/nginx: The Nginx configuration directory. All of the Nginx configuration files reside here.
- /etc/nginx/nginx.conf: The main Nginx configuration file. This can be modified to make changes to the Nginx global configuration.
- /etc/nginx/sites-available/: The directory where per-site “server blocks” can be stored. Nginx will not use the configuration files found in this directory unless they are linked to the sites-enabled directory (see below). Typically, all server block configuration is done in this directory, and then enabled by linking to the other directory.
- /etc/nginx/sites-enabled/: The directory where enabled per-site “server blocks” are stored. Typically, these are created by linking to configuration files found in the sites-available directory.
- /etc/nginx/snippets: This directory contains configuration fragments that can be included elsewhere in the Nginx configuration. Potentially repeatable configuration segments are good candidates for refactoring into snippets.
Server Logs（服务器日志）
- /var/log/nginx/access.log: Every request to your web server is recorded in this log file unless Nginx is configured to do otherwise.
- /var/log/nginx/error.log: Any Nginx errors will be recorded in this log.
