这篇文章主要介绍了Nginx 搭建域名访问环境的详细过程,通过示例代码讲解了Nginx 搭建转发网关进行负载均衡的相关操作,感兴趣的朋友跟随小编一起看看吧

1.Nginx配置文件

server {
    listen       80;
    server_name  www.gulimall.com;
    #charset koi8-r;
    #access_log  /var/log/nginx/log/host.access.log  main;
    location / {
        proxy_pass http://192.168.232.1:10001;
    }
    #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;
    #}
}

让所有的请求都转到，商品服务

2.Nginx 搭建转发网关进行负载均衡

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 192.168.232.1:88;
	}
    include /etc/nginx/conf.d/*.conf;
}

gulimall.conf

server {
    listen       80;
    server_name  www.gulimall.com;
    location / {
        proxy_pass http://gulimall;
    }
}

网关 application.yml

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

有个坑

因为nginx代理给网关的时候会 丢掉请求头里的host ，所以网关的匹配规则没有匹配上导致404

需要配置Nginx

在gulimall.conf

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

3.实现动静分离

 location /static {
        root   /usr/share/nginx/html;
		autoindex on;  #开启文件目录结构在网页显示
    }

注意路径会拼成， /usr/share/nginx/html/static

4.还有一个坑

这个匹配规则不要放前面，因为这些请求都是从上往下匹配的，匹配到了，就不往下匹配了，然而往nginx发送的域名都是 www.gulimall.com 所以，都会走第一个匹配，下面这些就匹配不上，就找不到那个接口就404了。

做好两点：

1.请求接口 http://域名/api/xxx

2.请求页面 http://域名

转发给网关，通过网关路由到对应的服务 !
