				<content:encoded><![CDATA[<p>EC2特点之一是允许用户随时更新实例状态，用户可以随时加入或删除实例，实例状态的动态变化方便了用户，但是却给防火墙的配置带来了麻烦。</p>
<p>AWS为了弥补EC2这一不足，引入了安全组（Security Group）概念。</p>
<p>安全组其实就是一组规则，用户利用这些规则来决定哪些网络流量会被实例接受，其他则被拒绝。一个用户目前最多可以创建100个安全组。当用户的实例被创建时，如果没有指定安全组，则系统自动将该实例分配给一个默认组（Default Group）。<br />
<strong> </strong></p>
<h2>Web服务器的安全组（Security Group）设定</h2>
<p><strong>1.选择EC2中「Security Groups」后，点击「Create Security Group」；</strong></p>
<p><a href="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Create-Security-Group1.png"><img class="attachment-medium" src="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Create-Security-Group1.png" alt="Create-Security-Group1" width="1429" height="664" /></a></p>
<p><strong>2.红色框内填写对应内容，点击「Create」；</strong></p>
<p><a href="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Security-Group-Configure.png"><img class="attachment-medium" src="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Security-Group-Configure.png" alt="Security-Group-Configure" width="1005" height="549" /></a></p>
<p><strong>3.安全组的名称为「ELB-SG」；</strong></p>
<p><a href="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Name.png"><img class="attachment-medium" src="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Name.png" alt="Name" width="1434" height="659" /></a></p>
<p><strong>4.选择该安全组(ELB-SG),「Outbound(出站)」设定允许所有；</strong></p>
<p><a href="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Outbound.png"><img class="attachment-medium" src="https://www.fuwuqiok.com/wp-content/uploads/2015/07/Outbound.png" alt="Outbound" width="1436" height="662" /></a></p>
<div class="alert alert-success"><strong>上述的安全规则，有其他设定内容，可参考安全组详细设计书。</strong></div>
<p><strong>EC2「Security Groups」中，下记6个安全组的状况确认；</strong></p>
