详解centos下搭建redis集群
<p><strong>必备的工具：</strong></p>
<p>
redis-3.0.0.tar</p>
<p>
redis-3.0.0.gem （ruby和redis接口）</p>
<p>
<strong>分析：</strong></p>
<p>
首先，集群数需要基数，这里搭建一个简单的redis集群（6个redis实例进行集群）。</p>
<p>
在一台服务器上操作，因此仅需要6个不同的端口号即可。分别是：7001、7002、7003、7004、7005、7006。</p>
<p>
<strong>步骤：</strong></p>
<p>
1、上传redis-3.0.0.tar到服务器（自己指定自己的软件目录），解压redis-3.0.0.tar。</p>
<p>
2、安装c语言环境（安装centos之后，自带c语言环境）</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_946254">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">yum </code><code class="bash functions">install</code> <code class="bash plain">gcc-c++</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
3、进入到redis-3.0.0目录</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_253454">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">make</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
4、安装redis到/usr/local/redis目录</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_326979">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">make</code> <code class="bash functions">install</code> <code class="bash plain">prefix=</code><code class="bash plain">/usr/local/redis</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
5、查看是否安装成功（出现bin目录即可）</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/f74b1854829658b967a2d5ee5017fe39.jpg"></p>
<p>
6、前端启动redis（进入上图的bin目录）</p>
<p>
./redis-server（开启）</p>
<p>
./redis-cli shutdown（关闭）</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/ba66b9b58972e5c5bf0521402803da1e.jpg"></p>
<p>
7、后端启动</p>
<p>
需要将redis解压之后的源码包中（redis-3.0.0目录下）的redis.conf文件拷贝到bin目录下</p>
<p>
修改redis.conf文件，将daemonize改为yes先要使用vim redis.conf</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/de19e95dc0a7a4bb050a2ef57fac1de2.jpg"></p>
<p>
使用命令后端启动redis</p>
<p>
bin目录下执行 ./redis-server redis.conf</p>
<p>
查看是否启动成功</p>
<p>

<p>
关闭后端启动的方式：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_995654">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">.</code><code class="bash plain">/redis-cli</code> <code class="bash functions">shutdown</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
以上是单独的redis安装，接下来搭建集群！</p>
<p>
<strong>安装ruby</strong></p>

<code class="bash plain">yum </code><code class="bash functions">install</code> <code class="bash plain">rubygems</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
<strong>将以下文件上传到linux系统</strong></p>
<p>
redis-3.0.0.gem （ruby和redis接口）</p>
<p>
进入该目录执行：gem install redis-3.0.0.gem</p>
<p>
将redis-3.0.0包下src目录中的以下文件拷贝到/usr/local/redis/redis-cluster/</p>
<p>
前提：先新建一个redis-cluster目录</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/45c8f6b91bcdfbaa0a029b904fa6da8e.jpg"></p>
<p>
搭建集群最少也得需要3台主机，如果每台主机再配置一台从机的话，则最少需要6台机器。</p>
<p>
端口设计如下：7001-7006</p>
<p>
第一步：复制出一个7001机器</p>
<p>
进入/usr/local/redis/目录执行 cp bin ./redis-cluster/7001 –r</p>
<p>
第二步：如果存在持久化文件，则删除</p>
<div class="jb51code">

<div class="syntaxhighlighterbash" id="highlighter_768758">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">rm</code> <code class="bash plain">-rf appendonly.aof dump.rdb</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
第三步：设置集群参数</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/21687df8d9eb4fc834cfc16cbd0ff4dd.jpg"></p>
<p>
第四步：修改端口</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/3392b83667ef019bf8dcd0a360ed8a42.jpg"></p>
<p>
第五步：复制出7002-7006机器</p>
<p>
给出我桌面系统下的目录结构：</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="详解centos下搭建redis集群" alt="详解centos下搭建redis集群" src="https://zhuji.jb51.net/uploads/img/202305/b8c0de7c5e6e39901ec25d857cc822a1.jpg"></p>
<p>
接下来设置一键启动全部redis或者关闭redis群：</p>
<p>
首先，新建一个文件，可以用vim打开一个不存在的文件，然后保存就存在了。(上图的start-all.sh和shutdow-all.sh就是我新建的)</p>
<p>
start-all.sh：</p>
