Linux下安裝Memcache

Memcache是一個開源項目，它是一個高性能的分布式的內存對象緩存系統，通過在內存裡維護一個統一的巨大的Hash表，能夠用來存儲各種格式的數據。

1: 還是下載

Memcache是用C編寫的，要用到C的libevent來處理接口

點擊下載memcached-1.4.0.tar.gz

下載libevent-2.0.13-stable.tar.gz

下載memcache-3.0.6.tgz

我下載到了/root/Downloads

2:解壓編譯

a：先安裝libevent

1. #cd /Downloads
2. #tar zvxf libevent-2.0.13-stable.tar.gz
3. #cd libevent-2.0.13-stable
4. #./configure --prefix=/usr
5. #make
6. #make install

查看下安裝是否成功

1. # ls -al /usr/lib | grep libevent

b. 安裝memcached

1. #cd ..
2. #tar zxvf memcached-1.4.0.tar.gz
3. #cd memcached-1.4.0
4. # ./configure –with-libevent=/usr
5. # make
6. # make install

c. 安裝memcache

1. #cd ..
2. #tar vxzf memcache-3.0.6.tgz
3. #cd memcache-3.0.6
4. #/usr/local/php/bin/phpize
5. #./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir
6. #make
7. #make install
8. #gvim /etc/php5/apache2/php.ini

修改php.ini中的extension_dir = “./”

1. extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-2007xxxx/”

添加

1. extension=memcache.so

3: 啟動和關閉

#/usr/local/bin/memcached -d -m 128 -u root -l 127.0.0.1 -p 11211 -c 256 -P /var/temp/memcached.pid

#kill `cat /var/temp/memcached.pid` 或者#killall memcached

重啟apache

sudo /etc/init.d/apche2 restart

4：測試

< ?php
$mem = new Memcache;
$mem->connect(“127.0.0.1″, 11211);
$mem->set(‘key’, ‘This is a test!’, 0, 60);
$val = $mem->get(‘key’);
echo $val;
?>

5: Ubuntu/debian 。

直接sudo

sudo apt-get install memcached

啟動

memcached -d -m 128 -p 11211 -u root -l 127.0.0.1

太輕松了。。。
