nginx:nginx:[emerg]"；“上游”；此处不允许在/etc/nginx/sites enabled/www.example.com.conf中使用指令

请问，有人能帮我吗？我必须在反向代理服务器上进行负载平衡，这不是我配置的。 当我配置上游指令时，它给出了一个错误。我已经尝试在http{}和包含的站点设置中设置它

我的nginx.conf

站点内的我的配置文件启用

    server 192.168.0.2;

}
server {

        listen   443 ssl;

        location / {
            proxy_pass  http://example;
        }
    
    
}

server {
    if ($host = www.example.com.br) {
        return 301 https://$host$request_uri;
    }
        listen   80;

您使用了括号

（

而不是大括号

{

。很抱歉，当我粘贴到这里时，将“{”替换为“）”，但在我的配置文件中它是{。您的上游块缺少一个名称。很抱歉，同样的错误。但现在我认为它是okUse

nginx-T

（大写

T

）查看所有包含文件的整个配置。在

上游

语句之前检查是否缺少关闭

}

。
