memcached是一套分布式的高速缓存系統,通常只是當作快取系統使用,所以使用memcached的應用程式在寫回較慢的系統時(像是後端的資料庫)需要額外的程式碼更新memcached內的資料。(reference from wiki)
預計完成的安裝環境
- libevent (memcached requirement)
- Memcached 1.4.15 Server, download it
- PHP Memcached extension 2.10, download it
Memcached Server
In MAMP:
brew install libevent
tar -zxvf memcached-1.4.15.tar.gz
cd memcached-1.4.15/
./configure --prefix=/Applications/MAMP/bin/php/php5.4.4/bin/php # depend on your PHP version
make
make install
Memcached Server Commands
- memcached -d -m 50 -p 11211 -u root # start memcached daemon, m: how many mega bytes you want, p: port
- killall memcached # stop memcached daemon
PHP Memcached extension
In MAMP
brew install libmemcached
tar -zxvf memcached-2.1.0.tgz
cd memcached-2.1.0/
/Applications/MAMP/bin/php/php5.4.4/bin/phpsize # to build PHP extension
./configure -enable-memcache -with-php-config=/Applications/MAMP/bin/php/php5.4.4/bin/php-config # depend on your PHP version
make
make install
You will see this message "/Applications/MAMP/bin/php/php5.4.4/lib/php/extensions/no-debug-non-zts-20100525/" if success
add "extension=memcached.so" to your php.ini and restart your web server
In Ubuntu
$ sudo apt-get install memcached
$ sudo apt-get install php5-memcached
$ sudo /etc/init.d/apache2 restart
Memcached Test Script
```<h2><span style="color: #3366ff;">Error "configure: error: Cannot find php_session.h" on MAMP</span></h2>
<ul>
<li><span style="line-height: 22px;"><a href="http://www.php.net/downloads.php" target="_blank">Download PHP source code depending on your PHP version</a></span></li>
<li>Unzip/tar the php source archive and move it to "/Applications/MAMP/bin/php/php5.4.4/include"</li>
<li>Rename the php source directory to just php (so then it will look like "/Applications/MAMP/bin/php/php5.4.4/include/php")</li>
<li>Run "./configure" under "/Applications/MAMP/bin/php/php5.4.4/include/php" to create header files</li>
</ul>
