理解并调通nginx的流程(实战篇)

从default文件构建配置文件，理解并调通nginx的流程

具体的参数配置文档：juejin.cn/post/697172…

我们可以在nginx.conf的文件中发现：其实是对conf.d文件中的配置文件有引用

所以我们可以直接在conf.d的文件中新增xxxxx.conf的文件，用来增加nginx的配置文件

我们之前在sites-available和sites-available文件中都发现了default的默认配置文件，可以将这个default复制一份到conf.d的文件夹下，然后重命名为waws.conf文件

操作如下：

• 拷贝文件到conf.d文件夹下

  • cp sites-available/default conf.d
    复制代码

  • 

• 将default复制一份叫waws.conf

  • cp default waws.conf
    复制代码

  • 

• 对waws.conf进行编辑

    # 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.

    # In most cases, administrators will remove this file from sites-enabled/ and
    # leave it as reference inside of sites-available where it will continue to be
    # updated by the nginx packaging team.
    #
    # This file will automatically load configuration files provided by other
    # applications, such as Drupal or WordPress. These applications will be made
    # available underneath a path with that package name, such as /drupal8.

    # Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

    # Default server configuration
    #
    server {
    	listen 3010 default_server;           # 只是对端口进行下修改
    	listen [::]:3010 default_server;
    
    	# 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/html;
    
    	# Add index.php to the list if you are using PHP
    	index index.html index.htm index.nginx-debian.html;
    
    	server_name _;
    
    	location / {
    		# First attempt to serve request as file, then
    		# as directory, then fall back to displaying a 404.
    		try_files $uri $uri/ =404;
    	}
    
    	# pass PHP scripts to FastCGI server
    	#
    	#location ~ \.php$ {
    	#	include snippets/fastcgi-php.conf;
    	#
    	#	# With php-fpm (or other unix sockets):
    	#	fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
    	#	# With php-cgi (or other tcp sockets):
    	#	fastcgi_pass 127.0.0.1:9000;
    	#}
    
    	# 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;
    #	}
    #}
    复制代码

• 然后我们保存文件，校验新生成的nginx配置文件的正确性

  • /usr/sbin/nginx -t
    复制代码

  • 

  • 出现上面的successful字段证明配置文件没有问题，报错自行修改配置文件

• 在重新启动nginx,加载配置文件

  • /usr/sbin/nginx -s reload
    复制代码

  • 

• 执行完毕后，我们去浏览器看效果

  • 

我们可以看到在default的下面有这样一个配置项的段：我们可以对他进行改造进行，进行复用

server {
    # 监听端口
	listen 80;
	listen [::]:80;

    # 和前面的80端口请求时候，对应多个x.x.x.x:80，可以通过server_name进行区分
	server_name example.com;

    # 访问路径
	root /var/www/example.com;
    # 访问返辉的数据是index.html
	index index.html;

    # 匹配请求路径，执行相对应的操作
	location / {
		try_files $uri $uri/ =404;
	}
}
