重点关注：http 服务中的 server(虚拟主机配置)

主要结构是：

http    {

    ...

    server    {
        #    监听的端口号
        listen                  8091;
        #    服务器名字，默认为    localhost    
        server_name         localhost;

        location    /    {
            #    代码位置
            #    当用root配置的时候，root后面指定的目录是上级目录
            #    并且该上级目录必须含有和location后指定的名称的同名目录，否则404
            #    root末尾的"/"加不加无所谓
            root    /Users/abc/project/React/;
                    #    index字段声明了解析的后缀名的先后顺序
                    index    index.html

        }

        #    404页面跳转到404.html，相对于上面的root目录
                    error_page        404                                                        /404.html;
                    #    403页面跳转到403.html，相对于上面的root目录
                    error_page        403                                                        /403.html;
                    #    50x页面跳转到50x.html
                    error_page            500    502    503    504        /50x.html;
                    location    =    /50x.html    {
                                    root            html;
                    }

    }

    ...

}

测试配置是否有错误

nginx -t #测试配置是否有错误

如果没有错误，则会提示：
