配置nginx动静分离全步骤

1、目的

高并发环境下，大量请求从服务器后端获取资源，给后台服务器造成了巨大的压力。因此，在发布代码时，需要将后端的静态资源放到nginx，形成动态文件和静态文件分离。静态文件就从nginx服务器上获取，动态文件就从后端服务器获取。

2、服务器加载静态资源的链路方式

（1）用户请求接口：

可以在hosts文件夹下设置：

192.168.52.130 gulimall.com

IP地址：代表nginx所在的服务器ip

域名代表要访问的接口；

（2）192.168.52.130服务器，接收到了80端口的请求，需要对gulimall.com这个域名进行处理。

配置文件如下：

[root@localhost conf]# vim nginx.conf 


user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;
    upstream gulimall{
      server 10.49.103.92:88; ##对gulimall进行处理，路由到服务器的网关
    }

    server{                        ##解析域名，映射到80端口
        listen 80;
        server_name gulimall.com
        location / {
                proxy_set_header Host $host;
                proxy_pass http://gulimall;
        }
    }


    include /etc/nginx/conf.d/*.conf;
}

 cp default.conf gulimall.conf

cat gulimall.conf

server {
    listen       80;
    server_name  gulimall.com;

    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;

    location /static/{
	root /usr/share/nginx/html;
    }

    location / {
	proxy_set_header Host $host;
	proxy_pass http://gulimall;
    }
    

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

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

docker restart nginx;

gulimall.com经过nginx路由到了服务器的网关服务，网关对gulimall.com进行断言

        - id: gulimall_host_route
          uri: lb://gulimall-product
          predicates:
            - Host=gulimall.com,item.gulimall.com

经过nacos，路由到了gulimall-product服务，gulimall-product的服务，再从nginx进行获取静态文件，而不用从后端服务器获取。

nginx服务器存储静态文件的地址：

 gulimll-product的html里边只需要：

<img src="/static/index/img/top_find_logo.png" alt="">
即可获取到nginx的静态资源。
