Redis-cli连接
<p>本文主要介绍创建ECS并开通白名单后,如何在ECS上安装Redis-cli客户端,并通过Redis-cli客户端访问Redis实例。Redis-cli是Redis自带的客户端,因此使用Redis-cli工具需要先安装Redis。</p>
<p><span style="font-size:18px"><strong>前提条件</strong></span></p>
<ol>
<li>您已成功创建Redis实例,可参考<a href="https://pinganyun.com/ssr/help/database/Redis/Getting_Started.Create_Redis" target="_blank">创建Redis实例</a>,且实例处于运行中。</li>
<li>您已成功创建ECS,可参考<a href="https://pinganyun.com/ssr/help/database/Redis/Getting_Started.Create_ECS" target="_blank">创建ECS</a>,且实例处于运行中。</li>
<li>您已成功开通白名单,可参考<a href="https://pinganyun.com/ssr/help/database/Redis/Getting_Started.Create_Whitelist" target="_blank">开通白名单</a>。</li>
</ol>
<p><span style="font-size:18px"><strong>注意事项</strong></span></p>
<p>ECS的操作系统请选择CentOS 7.x、RedHat Linux 7.x、Oracle Linux 7.x及以上的版本。</p>
<p><span style="font-size:18px"><strong>操作步骤</strong></span></p>
<p>1. 登录ECS,可参考<a href="https://pinganyun.com/ssr/help/compute/ecs/Quick_Start.Linux_Quick_Start.Login_Instance" target="_blank">登录Linux云主机</a>。</p>

<p> a. 若您ECS的操作系统不包含gcc编译环境,请执行以下命令安装。</p>
<table border="0" cellpadding="0" cellspacing="0">
<tbody>
<tr>
<td style="background-color:#f7f8fa; vertical-align:top">
<p><span style="font-family:Consolas">yum install gcc</span></p>
</td>
</tr>
</tbody>
</table>
<p> b. 执行以下命令下载Redis安装包,<a href="https://redis.io/download" target="_blank">下载地址</a>。</p>
