nginx已经正常运行！

9.配置反向代理

配置文件位置：/etc/nginx/conf.d/default.conf

编辑配置文件，替换里面的内容如下：

# 处理WebSocket连接
map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

server {
    listen       80;
    server_name  localhost;

	# 配置反向代理
    location ^~ /
    {
        proxy_pass http://127.0.0.1:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header REMOTE-HOST $remote_addr;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
        proxy_http_version 1.1;
  
        add_header X-Cache $upstream_cache_status;
    
        # 设置 Nginx 缓存
        set $static_fileG0ZQTXEv 0;
        if ( $uri ~* "\.(gif|png|jpg|css|js|woff|woff2)$" ) {
        	set $static_fileG0ZQTXEv 1;
        	expires 1m;
        }
        if ( $static_fileG0ZQTXEv = 0 ) {
			add_header Cache-Control no-cache;
        }
    }

    #禁止访问的文件或目录
    location ~ ^/(\.user.ini|\.htaccess|\.git|\.env|\.svn|\.project|LICENSE|README.md)
    {
        return 404;
    }
	
	access_log  /var/log/nginx/web.access.log;
    error_log  /var/log/nginx/web.error.log;
}

检查配置文件是不是正常

# 检查配置文件
nginx -t

# 输出下面内容证明配置文件没有错误
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

检查正常后，重载配置生效

# 重新加载nginx配置
nginx -s reload
