一：redis安装

Download, extract and compile Redis with:

<ol>
<li value="1">
<span>$ wget http</span><span>:</span><span>//download.redis.io/releases/redis-3.0.4.tar.gz</span>
</li>
<li>
<span>$ tar xzf redis</span><span>-</span><span>3.0</span><span>.</span><span>4.tar</span><span>.</span><span>gz</span>
</li>
<li>
<span>$ cd redis</span><span>-</span><span>3.0</span><span>.</span><span>4</span>
</li>
<li><span>$ make</span></li>
</ol>

The binaries that are now compiled are available in the src directory. Run Redis with:

<ol><li value="1">
<span>$ src</span><span>/</span><span>redis</span><span>-</span><span>server</span>
</li></ol>

You can interact with Redis using the built-in client:

<ol><li value="1">
<span>$ src</span><span>/</span><span>redis</span><span>-</span><span>cli</span>
</li></ol>

redis> set foo bar
OK
redis> get foo
"bar"

二、php扩展：
更多版本:http://pecl.php.net/package/redis

<ol>
<li value="1">
<span>wget http</span><span>:</span><span>//pecl.php.net/get/redis-2.2.5.tgz</span>
</li>
<li><span>#解压</span></li>
<li>
<span>tar zxvf redis</span><span>-</span><span>2.2</span><span>.</span><span>5.tgz</span>
</li>
<li><span>#进入安装目录</span></li>
<li>
<span>cd redis</span><span>-</span><span>2.2</span><span>.</span><span>5</span>
</li>
<li>
<span>/</span><span>usr</span><span>/</span><span>local</span><span>/</span><span>php</span><span>/</span><span>bin</span><span>/</span><span>phpize</span>
</li>
<li><span>#配置</span></li>
<li>
<span>./</span><span>configure </span><span>--</span><span>with</span><span>-</span><span>php</span><span>-</span><span>config</span><span>=</span><span>/usr/</span><span>local</span><span>/</span><span>php</span><span>/</span><span>bin</span><span>/</span><span>php</span><span>-</span><span>config</span>
</li>
<li><span>#编译安装</span></li>
<li>
<span>make  </span><span>&&</span><span> make install</span>
</li>
</ol>

安装完成之后，出现下面的安装路径
/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
配置php支持
#编辑配置文件，在最后一行添加以下内容

<ol>
<li value="1">
<span>vim </span><span>/</span><span>usr</span><span>/</span><span>local</span><span>/</span><span>php</span><span>/</span><span>etc</span><span>/</span><span>php</span><span>.</span><span>ini  </span>
</li>
<li>
<span>extension</span><span>=</span><span>"redis.so"</span>
</li>
</ol>

这个时候phpinfo()就可以看到redis扩展了。
redis小例子：

<ol>
<li value="1">
<span>$redis </span><span>=</span><span>new</span><span> redis</span><span>();</span>
</li>
<li>
<span>$test</span><span>=</span><span>$redis</span><span>-></span><span>connect</span><span>(</span><span>'127.0.0.1'</span><span>,</span><span>6379</span><span>);</span>
</li>
<li>
<span>var_dump</span><span>(</span><span>$test</span><span>);</span>
</li>
<li><span> </span></li>
<li>
<span>$result </span><span>=</span><span> $redis</span><span>-></span><span>set</span><span>(</span><span>'test'</span><span>,</span><span>"webyang.net"</span><span>);</span>
</li>
<li>
<span>var_dump</span><span>(</span><span>$result</span><span>);</span><span>//结果：bool(true)</span>
</li>
<li><span> </span></li>
<li>
<span>$result </span><span>=</span><span> $redis</span><span>-></span><span>get</span><span>(</span><span>'test'</span><span>);</span>
</li>
<li>
<span>var_dump</span><span>(</span><span>$result</span><span>);</span><span>//结果：string(11) "webyang.net"</span>
</li>
</ol>

之所以搞这些，是因为公司用阿里的RDS，偶尔瞬间并发高的时候会卡死，CPU直接百分百，RDS是12g的内存，最大IOPS 6000，最大链接数 2000，实际我们远没达到这个数，所以考虑搞个redis队列玩玩，把一些没必要实时执行的东西放到队列中执行。本来想设置在数据存入几分钟后直接执行队列的，没想到好的方法，只能在linux写个脚本固定每个几分钟跑一次了，其实相对来说，这种并不是很智能，存在一些资源浪费，大家有什么好的想法吗？求头脑风暴~

以上就介绍了linux安装redis服务以及php redis扩展，包括了队列方面的内容，希望对PHP教程有兴趣的朋友有所帮助。
