<h2 id="2谁在使用低代码"><a class="markdownIt-Anchor" href="#2谁在使用低代码"></a> 2.谁在使用低代码？</h2>
<p> 低代码技术显著降低了软件开发的技术门槛，让更多人可以参与到软件开发中，进一步扩大软件开发者的规模，加速信息化建设。都有谁适合使用低代码技术开发软件？</p>
<p> 从事低代码开发人员可以分成两类：服务于企业IT部门或软件的公司的IT技术人员（包含但不限于程序员、项目经理、实施顾问等）；以及来自业务部门，本职工作与IT无关但参与到软件开发中的业务开发者。</p>
<h3 id="低代码赋能it技术人员"><a class="markdownIt-Anchor" href="#低代码赋能it技术人员"></a> 低代码赋能IT技术人员</h3>
<p> 这里的IT技术人员是与“业务开发者”相对的概念，包含但不限于程序员，特指在企业或信息化提供商中，本职工作为企业信息化相关的技术人员。IT技术人员主要集中在企业信息化部门和为企业提供信息化服务（如外包开发、系统集成等）的软件公司中，典型岗位有项目经理、架构师、程序员、测试人员、实施和运维人员、DevOps等。</p>
<p>####整体而言，IT技术人员具备以下特征：</p>
<p> 具备技能：通常具有计算机相关的教育背景，或通过自学的方式掌握了一定的IT技能（如编程语言、数据库管理、配置管理、系统管理等）<br>
考核指标：能否保质保量地满足本单位或客户的信息化需求是核心指标<br>
学习意愿：需要紧跟技术发展趋势，跟随团队和企业技术决策，及时更新技术能力</p>
<h2 id="3赋能业务人员"><a class="markdownIt-Anchor" href="#3赋能业务人员"></a> 3.赋能业务人员</h2>
<p> 在低代码技术被命名之前，国际知名的研究机构们就提出了“业务开发者/平民开发者”的概念。这两个概念与专业开发者对应，专指那些向业务部门汇报有开发能力来辅助业务发展的员工。这些人和向IT部门报告的专业开发者不同，他们的主要工作职责是业务发展，软件开发只是一个辅助性工作，通常不会有相关的考核指标，得到的资源也较为有限。在传统的编码开发时代，业务开发者较为少见，有能力从事辅助性软件开发的业务人员主要集中在数据分析师、软件公司的程序员（程序员的主要工作是开发软件产品或对外交付软件项目，而不是辅助性的软件工具）等具备编程能力的人群。而低代码技术的出现，让更多的业务人员可以成为业务开发者，比如构建订单管理应用的销售主管、人事档案系统的HR、库存盘点APP的库管人员等。</p>
<h3 id="整体而言业务开发者具备以下特征"><a class="markdownIt-Anchor" href="#整体而言业务开发者具备以下特征"></a> 整体而言，业务开发者具备以下特征：</h3>
<p> 具备技能：通常没有计算机相关的教育背景，部分掌握Excel等办公软件的常用功能；<br>
考核指标：能否完成业务目标是核心指标，通常不包含信息化建设相关内容；<br>
学习意愿：不得不参与软件开发，通常没有主动学习IT相关技术的动力和投入；</p>
<h2 id="4对业务开发者的价值"><a class="markdownIt-Anchor" href="#4对业务开发者的价值"></a> 4.对业务开发者的价值</h2>
<p> 与帮助IT技术人员提升软件开发效率不同，低代码对于大多数业务开发者而言，是解决了“能不能开发软件”的问题。这就意味着，业务人员可以根据自身的应用场景，快速构建起对应的软件应用，减少了与IT部门协调确认的沟通成本，在IT部门资源紧缺的背景下，尽快扫清信息化死角。<br>
业务开发者构建的应用主要有以下几类，除数据报表应用的业务逻辑复杂度较高而且通常需要与第三方系统集成，对业务开发者有较高的学习能力要求外，其他应用场景相对简单，更适合业务开发者使用低代码构建。</p>
<h2 id="5低代码的应用价值"><a class="markdownIt-Anchor" href="#5低代码的应用价值"></a> 5.低代码的应用价值</h2>
<p> 低代码开发平台可以显著提升软件开发的效率，可广泛应用于各行业数字化转型升级。具体而言，开发者可以使用低代码开发平台，更简单、更快速地构建个性化应用，打造数字化平台。</p>

<p> Transformer模型的核心思想是使用自注意力机制（Self-Attention Mechanism）来捕捉输入序列中的依赖关系。这种机制允许模型在处理每个输入元素时，都能够关注到输入序列中的所有其他元素，从而能够捕捉到更长的依赖关系。此外，Transformer模型还采用了位置编码（Positional Encoding）来弥补模型本身不具备处理序列顺序的能力。</p>
<p> Transformer模型由两部分组成：编码器（Encoder）和解码器（Decoder）。编码器负责将输入序列转换为一系列向量表示，而解码器则负责根据这些向量表示生成输出序列。这两部分都由多个相同的层堆叠而成，每一层都包含一个多头自注意力子层和一个简单的全连接前馈神经网络。</p>
<p> 由于Transformer模型不依赖RNN的顺序结构，因此它可以实现高效的并行化训练，这使得它在处理大规模数据集时具有显著的优势。此外，Transformer模型的强大表示能力和灵活性使得它在多个NLP任务上都取得了显著的效果，成为了自然语言处理领域的一种主流模型。</p>
<p> 总的来说，Transformer模型是Google研究团队在2017年提出的一种基于自注意力机制的深度学习模型，它的出现为自然语言处理领域的发展带来了革命性的突破。</p>

<span id="more"></span>
<p>1.创建用户，一定要记住密码</p>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">sudo adduser git</span><br><span class="line">su git</span><br><span class="line">cd ~</span><br></pre></td></tr></table></figure>
<p>2.下载并解压安装包</p>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">wget https://dl.gogs.io/0.11.43/gogs_0.11.43_linux_amd64.zip</span><br><span class="line">unzip gogs_0.11.43_linux_amd64.zip</span><br></pre></td></tr></table></figure>
<p>3.拷贝启动项到系统下</p>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">cp /home/xx/gogs/scripts/init/debian/gogs /etc/init.d/</span><br><span class="line">chmod +x /etc/init.d/gogs</span><br></pre></td></tr></table></figure>

<span id="more"></span>
<p>1.安装 nginx</p>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">apt update</span><br><span class="line">apt install nginx</span><br></pre></td></tr></table></figure>

<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">openssl dhparam -out /var/www/ssl/dhparam.pem 2048</span><br><span class="line">备注：注意观察的话，证书和dhparam.pem的目录和nginx中是保持一致的。</span><br></pre></td></tr></table></figure>
<p>7.查看定时更换任务</p>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">$ crontab -l</span><br><span class="line">0 0 * * * "/home/ubuntu/.acme.sh"/acme.sh --cron --home "/home/ubuntu/.acme.sh" > /dev/null</span><br></pre></td></tr></table></figure>

<p> 数据表明以上几种方式在<code>InnoDB</code>和<code>MyISAM</code>引擎中，查询效率差别很大。</p>
<p> <code>MyISAM</code>把总行数存在磁盘(<code>information_schema.partitions</code>)中，<code>count(*)</code>和<code>count(1)</code>的性能会好很多。</p>
<p> <code>InnoDB</code>获取所有数据，并逐行计算总行数，<code>count(*)</code>和<code>count(1)</code>的性能会差很多。`</p>

<h1 id="3-性能优化"><a class="markdownIt-Anchor" href="#3-性能优化"></a> 3. 性能优化</h1>
<p> 在实际开发过程中，业务系统的数据表均使用<code>InnoDB</code>支持事务。</p>
<p> 该如何优化<code>InnoDB</code>中<code>count</code>的性能？</p>
<ul class="lvl-0">
<li class="lvl-2">
<p>使用<code>redis</code>记录数据行数</p>

<span id="more"></span>
<blockquote>
<p>Nginx：Nginx (“engine x”) ，Nginx (“engine x”) 是俄罗斯人 Igor Sysoev(塞索耶夫)编写的一款高性能的 HTTP 和反向代理服务器。也是一个 IMAP/POP3/SMTP 代理服务器；也就是说，Nginx 本身就可以托管网站，进行 HTTP 服务处理，也可以作为反向代理服务器使用。</p>
</blockquote>
<h1 id="nginx-特点"><a class="markdownIt-Anchor" href="#nginx-特点"></a> nginx 特点</h1>
<ul class="lvl-0">
<li class="lvl-2">
<p>跨平台：Nginx 可以在大多数 Unix like OS 编译运行，而且也有 Windows 的移植版本。</p>
</li>
<li class="lvl-2">
<p>配置异常简单：非常容易上手。配置风格跟程序开发一样，神一般的配置</p>
</li>
<li class="lvl-2">
<p>非阻塞、高并发连接：数据复制时，磁盘 I/O 的第一阶段是非阻塞的。官方测试能够支撑 5 万并发连接，在实际生产环境中跑到 2 ～ 3 万并发连接数.(这得益于 Nginx 使用了最新的 epoll 模型)</p>
</li>
<li class="lvl-2">
<p>事件驱动：通信机制采用 epoll 模型，支持更大的并发连接。</p>
</li>
</ul>
<h1 id="nginx-特性"><a class="markdownIt-Anchor" href="#nginx-特性"></a> nginx 特性</h1>
<p><strong>master/worker 结构：</strong> 一个 master 进程，生成一个或多个 worker 进程</p>
<p><strong>内存消耗小：</strong> 处理大并发的请求内存消耗非常小。在 3 万并发连接下，开启的 10 个 Nginx 进程才消耗 150M 内存（15M*10=150M）</p>
<p><strong>成本低廉：</strong> Nginx 为开源软件，可以免费使用。而购买 F5 BIG-IP、NetScaler 等硬件负载均衡交换机则需要十多万至几十万人民币</p>
<p><strong>内置的健康检查功能：</strong> 如果 Nginx Proxy 后端的某台 Web 服务器宕机了，不会影响前端访问。</p>
<p><strong>节省带宽：</strong> 支持 GZIP 压缩，可以添加浏览器本地缓存的 Header 头。</p>
<p><strong>稳定性高：</strong> 用于反向代理，宕机的概率微乎其微</p>
<p>1、nginx 代理和后端 web 服务器间无需长连接；</p>
<p>2、接收用户请求是异步的，即先将用户请求全部接收下来，再一次性发送后后端 web 服务器，极大的减轻后端 web 服务器的压力</p>
<p>3、发送响应报文时，是边接收来自后端 web 服务器的数据，边发送给客户端的</p>
<p>4、网络依赖型低。NGINX 对网络的依赖程度非常低，理论上讲，只要能够 ping 通就可以实施负载均衡，而且可以有效区分内网和外网流量</p>
<p>5、支持服务器检测。NGINX 能够根据应用服务器处理页面返回的状态码、超时信息等检测服务器是否出现故障，并及时返回错误的请求重新提交到其它节点上</p>
