Please support for more: http://www.webyang.net/Html/web/article_174.html

One: redis installation

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>

is completed, the following installation path appears
/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/
Configure PHP support
#Edit the configuration file and add the following content in the last line

<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>

At this time, phpinfo() can see the redis extension.
Redis small example:

<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>

The reason why we do this is because the company uses Alibaba’s RDS. Occasionally, when the concurrency is high, it will freeze, and the CPU will directly run 100%. RDS has 12g of memory, maximum IOPS 6000, and maximum number of links. 2000. In fact, we are far from reaching this number, so we are considering building a redisqueue for fun, and put some things that are not necessary to be executed in real time into the queue for execution. I originally wanted to set up the queue to be executed directly after a few minutes after the data is stored. I didn't think of a good way. I could only write a script in Linux and run it every few minutes. In fact, relatively speaking, this is not very smart. , there is some waste of resources, do you have any good ideas? Please brainstorm~ The above introduces the Linux installation of redis service and PHP redis extension, including queue content. I hope it will be helpful to friends who are interested in PHP tutorials.
