运用VPS那样容易？不如先搞定VPS设置
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在本文中亚洲云端Asia.Cloud将分五个<span style="color: black;">过程</span>介绍<span style="color: black;">怎样</span>设置VPS，<span style="color: black;">包含</span><span style="color: black;">怎样</span><span style="color: black;">经过</span>SSH<span style="color: black;">拜访</span>登录到VPS、更新主机、创建新用户并修改、启用公钥认证、<span style="color: black;">加强</span>安全。<span style="color: black;">不外</span>，在<span style="color: black;">认识</span>这些细节之前，先得清楚<span style="color: black;">为何</span><span style="color: black;">必须</span>配置新的虚拟主机。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">一般</span>，<span style="color: black;">有些</span>基本主机计划会交由服务商设置<span style="color: black;">运用</span>它所需的所有软件，例如，共享主机中用户可能会立即<span style="color: black;">拜访</span>账户的<span style="color: black;">掌控</span>面板，该<span style="color: black;">掌控</span>面板<span style="color: black;">供给</span>配置所需的所有选项。<span style="color: black;">然则</span>在大<span style="color: black;">都数</span><span style="color: black;">状况</span>下，<span style="color: black;">无</span>机会<span style="color: black;">调节</span>主机的<span style="color: black;">实质</span>设置，<span style="color: black;">由于</span>其他人<span style="color: black;">亦</span>在<span style="color: black;">运用</span>同一台<span style="color: black;">设备</span>。<span style="color: black;">因此</span>借助VPS，用户<span style="color: black;">能够</span><span style="color: black;">得到</span>一个独立的主机环境。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">之后，便轮到VPS设置环节：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">过程</span>1：<span style="color: black;">经过</span>SSH<span style="color: black;">拜访</span>登录VPS</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">除了<span style="color: black;">运用</span>浏览器之外，还<span style="color: black;">能够</span><span style="color: black;">经过</span>多种方式连接到网站。例如，用户<span style="color: black;">能够</span><span style="color: black;">运用</span>文件传输协议（FTP），该协议使其<span style="color: black;">能够</span>上传、下载和编辑主机上的文件。<span style="color: black;">不外</span>，尽管FTP可能<span style="color: black;">特别有</span>用，<span style="color: black;">然则</span>该协议<span style="color: black;">没</span>法<span style="color: black;">运用</span>户向主机发出命令。<span style="color: black;">因此呢</span>，<span style="color: black;">必须</span><span style="color: black;">运用</span>Secure Shell（SSH）<span style="color: black;">拜访</span>，这是另一种协议类型，可<span style="color: black;">供给</span>对远程服务器的<span style="color: black;">拜访</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">经过</span>SSH连接后，就<span style="color: black;">能够</span>向服务器发出命令。SSH还以其强大的加密和身份验证协议而闻名，这使其高度安全。<span style="color: black;">经过</span>学习<span style="color: black;">怎样</span><span style="color: black;">运用</span>SSH，将迈入主机管理的<span style="color: black;">第1</span>步。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">过程</span>2：更新主机</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">软件包本质上是<span style="color: black;">运用</span>Unix的软件。<span style="color: black;">针对</span>任何系统，保持其组件最新都是很<span style="color: black;">要紧</span>的，主机<span style="color: black;">亦</span>不例外。<span style="color: black;">倘若</span><span style="color: black;">运用</span>的软件过时，则会向主机（和网站）开放安全漏洞。<span style="color: black;">另一</span>，可能会<span style="color: black;">错失</span>新功能或改进的性能。这<span style="color: black;">便是</span><span style="color: black;">为何</span>您要做的<span style="color: black;">第1</span>件事<span style="color: black;">便是</span>更新服务器的软件包，并下载所有安全补丁。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">过程</span>3：新用户与权限修改</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">设置VPS时，<span style="color: black;">首要</span>要<span style="color: black;">运用</span>root，该用户是到<span style="color: black;">日前</span>为止<span style="color: black;">始终</span>在<span style="color: black;">运用</span>的帐户。<span style="color: black;">然则</span>，<span style="color: black;">一般</span>最好设置一个<span style="color: black;">拥有</span>超级用户权限的用户帐户。<span style="color: black;">这般</span>做的<span style="color: black;">原由</span>是，<span style="color: black;">倘若</span>不确定自己在做什么， root 帐户可能会<span style="color: black;">导致</span><span style="color: black;">有些</span>严重损害。一个root帐户<span style="color: black;">持有</span>完全<span style="color: black;">拜访</span>所有的系统设置，可能让一个错误的命令<span style="color: black;">导致</span>严重的问题。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">过程</span>4：启用公钥认证</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">公钥认证是一种比常规<span style="color: black;">暗码</span>更安全的技术。<span style="color: black;">运用</span>这种<span style="color: black;">办法</span>，将生成一组“公用”和“专用”密钥。主机将存储公钥，并<span style="color: black;">运用</span>它来认证私钥，<span style="color: black;">仅有</span>用户<span style="color: black;">才可</span>将其<span style="color: black;">做为</span>文件在计算机上<span style="color: black;">拜访</span>。设置公钥身份验证后，则将<span style="color: black;">必须</span>私钥和<span style="color: black;">暗码</span>短语<span style="color: black;">才可</span>登录，可大大<span style="color: black;">加强</span>安全性。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">而要在Windows中生成SSH密钥，<span style="color: black;">能够</span><span style="color: black;">运用</span>PuTTYgen应用程序，该应用程序在较早设置客户端时已安装，用户<span style="color: black;">能够</span>在程序中寻找它并运行。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">过程</span>5：<span style="color: black;">加强</span>安全</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">倘若</span>要<span style="color: black;">保证</span>服务器安全，还<span style="color: black;">必须</span>执行最后一步，那<span style="color: black;">便是</span>为其启用可<span style="color: black;">运用</span>的安全<span style="color: black;">办法</span>。像<span style="color: black;">有些</span>用户<span style="color: black;">能够</span><span style="color: black;">运用</span>iptables程序执行此操作，该程序<span style="color: black;">能够</span>设置规则以限制往返于主机的流量。<span style="color: black;">然则</span>，此过程有点<span style="color: black;">繁杂</span>，<span style="color: black;">因此呢</span><span style="color: black;">咱们</span><span style="color: black;">意见</span>查看<span style="color: black;">相关</span><span style="color: black;">怎样</span>设置iptables和正确配置程序的完整指南。</p>
