一：redis安裝

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 compile Redis with:
are 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擴充：
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>

安裝完成之後，出現下面的安裝路徑
/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
配置php支援
#編輯配置文件，在最後一行添加以下內容

<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>

這時候phpinfo()就可以看到redis擴充了。
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>

之所以搞這些，是因為公司用阿里的RDS，偶爾瞬間並發高的時候會卡死，CPU直接百分百，RDS是12g的內存，最大IOPS 6000，最大鏈結數2000，實際我們遠遠沒有達到這個數，所以考慮搞個redis隊列玩玩，把一些沒必要實時執行的東西放到隊列中執行。本來想設定在資料存入幾分鐘後直接執行隊列的，沒想到好的方法，只能在linux寫個腳本固定每個幾分鐘跑一次了，其實相對來說，這種並不是很智能，存在一些資源浪費，大家有什麼好的想法嗎？求腦力激盪~

以上就介紹了linux安裝redis服務以及php redis擴展，包括了隊列方面的內容，希望對PHP教程有興趣的朋友有所幫助。
