**基于Docker搭建Redis集群**

环境：6个节点，三主三从

制作Redis镜像：docker build -f dockerfile -t jiang/redis-cluster:4.0.1 .

dockerfile文件：

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 7 8 9 10 11 </td> 
 <td> <code>FROM redis:4.0.1</code> <code>ENV TZ=Asia</code><code>/Shanghai</code> <code>RUN&nbsp;</code><code>ln</code>&nbsp;<code>-snf&nbsp;</code><code>/usr/share/zoneinfo/</code><code>$TZ&nbsp;</code><code>/etc/localtime</code>&nbsp;<code>&amp;&amp;&nbsp;</code><code>echo</code>&nbsp;<code>$TZ &gt;&nbsp;</code><code>/etc/timezone</code> <code>RUN&nbsp;</code><code>mkdir</code>&nbsp;<code>/usr/local/etc/redis</code>&nbsp;<code>&amp;&amp;&nbsp;</code><code>chown</code>&nbsp;<code>redis:redis&nbsp;</code><code>/usr/local/etc/redis</code> <code>ENV REDIS_C=</code><code>/usr/local/etc/redis</code> <code>RUN&nbsp;</code><code>echo</code>&nbsp;<code>"port 6379"</code>&nbsp;<code>&gt; $REDIS_C</code><code>/redis</code><code>.conf</code> <code>RUN&nbsp;</code><code>echo</code>&nbsp;<code>"cluster-enabled yes"</code>&nbsp;<code>&gt;&gt; $REDIS_C</code><code>/redis</code><code>.conf</code> <code>RUN&nbsp;</code><code>echo</code>&nbsp;<code>"cluster-config-file nodes.conf"</code>&nbsp;<code>&gt;&gt; $REDIS_C</code><code>/redis</code><code>.conf</code> <code>RUN&nbsp;</code><code>echo</code>&nbsp;<code>"cluster-node-timeout 5000"</code>&nbsp;<code>&gt;&gt; $REDIS_C</code><code>/redis</code><code>.conf</code> <code>RUN&nbsp;</code><code>echo</code>&nbsp;<code>"appendonly yes"</code>&nbsp;<code>&gt;&gt; $REDIS_C</code><code>/redis</code><code>.conf</code> <code>CMD [&nbsp;</code><code>"redis-server"</code><code>,&nbsp;</code><code>"/usr/local/etc/redis/redis.conf"</code>&nbsp;<code>]</code> </td> 
 </tr> 
 </tbody> 
</table>

制作Ruby镜像：docker build -f dockerfile2 -t jiang/my\_ruby:2.4 .

dockerfile2文件：

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 </td> 
 <td> <code>FROM ruby:2.4</code> <code>RUN gem&nbsp;</code><code>install</code>&nbsp;<code>redis</code> <code>ADD .</code><code>/redis-4</code><code>.0.1.tgz&nbsp;</code><code>/usr/local</code> <code>RUN&nbsp;</code><code>cd</code>&nbsp;<code>/usr/local</code>&nbsp;<code>&amp;&amp;&nbsp;</code><code>ln</code>&nbsp;<code>-sf redis-4.0.1 redis</code> </td> 
 </tr> 
 </tbody> 
</table>

分别启动6个节点实例:

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 </td> 
 <td> <code>docker run --name redis7000 -p 7000:6379 -d jiang</code><code>/redis-cluster</code><code>:4.0.1</code> <code>docker run --name redis7001 -p 7001:6379 -d jiang</code><code>/redis-cluster</code><code>:4.0.1</code> <code>docker run --name redis7002 -p 7002:6379 -d jiang</code><code>/redis-cluster</code><code>:4.0.1</code> <code>docker run --name redis7003 -p 7003:6379 -d jiang</code><code>/redis-cluster</code><code>:4.0.1</code> <code>docker run --name redis7004 -p 7004:6379 -d jiang</code><code>/redis-cluster</code><code>:4.0.1</code> <code>docker run --name redis7005 -p 7005:6379 -d jiang</code><code>/redis-cluster</code><code>:4.0.1</code> </td> 
 </tr> 
 </tbody> 
</table>

查看6个节点的容器IP

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 6 </td> 
 <td> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>redis7000</code> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>redis7001</code> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>redis7002</code> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>redis7003</code> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>redis7004</code> <code>docker inspect --</code><code>format</code><code>=</code><code>'{ {.NetworkSettings.IPAddress}}'</code>&nbsp;<code>redis7005</code> </td> 
 </tr> 
 </tbody> 
</table>

启动Ruby容器，进入/bin/bash，创建redis集群

<table> 
 <tbody> 
 <tr> 
 <td> 1 2 3 4 5 </td> 
 <td> <code>docker run -it jiang</code><code>/my_ruby</code><code>:2.4&nbsp;</code><code>/bin/bash</code> <code># /usr/local/redis/src/redis-trib.rb create --replicas 1 172.17.0.2:6379 172.17.0.3:6379 172.17.0.4:6379 172.17.0.5:6379 172.17.0.6:6379 172.17.0.7:6379</code> <code>出现下面显示说明集群创建成功：</code> <code>[OK] All nodes agree about slots configuration.</code> <code>[OK] All 16384 slots covered.</code> </td> 
 </tr> 
 </tbody> 
</table>

宿主机上利用redis客户端简单测试：

./redis-cli -c -p 7000
