假如项目通过自动化部署在了docker容器里面：教程在这里vue使用docker+node+nginx+linux自动化部署_1024小神的博客-CSDN博客

怎么将nginx通过域名绑定到这个容器呢？

例如我们将一个二级域名绑定second.1024shen.com/#/ 到我们的服务

我们需要先在域名解析里面添加我们的这个二级域名：主机记录就是二级域名，像普通的www其实也是二级域名的范畴了，哈哈哈哈

然后添加一个新的nginx配置文件：一般都在/etc/nginx/sites-available这个里面：

添加的配置内容如下：

需要修改两个地方：一个二级域名，一个容器的端口

# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

# Default server configuration
#
server {
	listen 80;
	listen [::]:80;

	# SSL configuration
	#
	# listen 443 ssl default_server;
	# listen [::]:443 ssl default_server;
	#
	# Note: You should disable gzip for SSL traffic.
	# See: https://bugs.debian.org/773332
	#
	# Read up on ssl_ciphers to ensure a secure configuration.
	# See: https://bugs.debian.org/765782
	#
	# Self signed certs generated by the ssl-cert package
	# Don't use them in a production server!
	#
	# include snippets/snakeoil.conf;

	# root /var/www/second;

	# Add index.php to the list if you are using PHP
	index index.html index.htm index.nginx-debian.html;
    
    # second.1024shen.com就是二级域名
	server_name second.1024shen.com;

	location / {
		# First attempt to serve request as file, then
		# as directory, then fall back to displaying a 404.
        # http://127.0.0.1:9090/这个就是容器的本地ip:端口
		proxy_pass http://127.0.0.1:9090/;
		# try_files $uri $uri/ =404;
	}

	# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
	#
	#location ~ \.php$ {
	#	include snippets/fastcgi-php.conf;
	#
	#	# With php7.0-cgi alone:
	#	fastcgi_pass 127.0.0.1:9000;
	#	# With php7.0-fpm:
	#	fastcgi_pass unix:/run/php/php7.0-fpm.sock;
	#}

	# deny access to .htaccess files, if Apache's document root
	# concurs with nginx's one
	#
	#location ~ /\.ht {
	#	deny all;
	#}
}


# Virtual Host configuration for example.com
#
# You can move that to a different file under sites-available/ and symlink that
# to sites-enabled/ to enable it.
#
#server {
#	listen 80;
#	listen [::]:80;
#
#	server_name example.com;
#
#	root /var/www/example.com;
#	index index.html;
#
#	location / {
#		try_files $uri $uri/ =404;
#	}
#}

 然后还要为这个配置创建一个软连接：

linux创建软连接命令： ln -s [dir1] [dir2]  ，dir1是真实的文件夹/文件夹，dir2是dir1的软链接。

将软连接放在/etc/nginx/sites-enabled下面，软连接相当于快捷方式，连接到second文件地址：

然后使用nginx -t 测试一下nginx配置是否正确：

nginx -t

如果没有问题，就重新加载配置： 

 nginx -s reload

 恭喜你，现在已经成功了，打开二级域名访问一下：
