我的版本爲Centos Release 5.5 (Final)
使用這個命令可以知道你的Linux版本
cat /etc/redhat-release
1.要安裝libevent庫。
cd /usr/local/src
curl -O http://monkey.org/~provos/libevent-1.4.10-stable.tar.gz
tar xzvf libevent-1.4.10-stable.tar.gz
cd libevent-1.4.10-stable
./configure --prefix=/usr/local
make
make install
2.接下來就是安裝memcached
cd /usr/local/src
wget http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz
tar xzvf memcached-1.4.5.tar.gz
cd memcached-1.4.5
./configure
make
make install
memcached 是在/usr/local/bin/memcahced下
安裝完畢後，用下面這個命令以用戶root來運行memcache
memcached -u root -d -m 64 -l 192.168.0.101 -p 11211
root 爲所執行的用戶
64 爲緩存大小64M
192.168.0.101 爲所在的服務器IP地址
11211 是所在端口
要關閉memcache
pkill memcached
3.接下來是安裝php-pecl-memcache
http://pecl.php.net/package/memcache
這個詳細配置可查看php的源碼安裝
http://www.uusnn.com.cn/index.php/archives/148
查看memcache的運行情況，可以用memcache.php來查看。
4.memcached測試
$mc = new memcache();
//用addServer比用connect要好
$mc->addServer('192.168.0.101', 11211) or die ("Could not connect");
$mc->set('uusnn','ttt');
//$mc->delete('uusnn');
$a = $mc->get('uusnn');
print_r($a);
5.推薦使用方式
The directives are used by the MemcachePool constructor so you can instantiate
several pools with different settings by using ini_set() creativly. For example
ini_set('memcache.protocol', 'binary');
$binarypool = new MemcachePool();
$binarypool->addServer(...)
ini_set('memcache.protocol', 'ascii');
ini_set('memcache.redundancy', '2');
$redundantpool = new MemcachePool();
$redundantpool->addServer(...)
ini_set('memcache.redundancy', '1');
The new interface looks like
class MemcachePool() {
bool connect(string host, int tcp_port = 11211, int udp_port = 0, bool persistent = true, int weight = 1, int timeout = 1, int retry_interval = 15)
bool addServer(string host, int tcp_port = 11211, int udp_port = 0, bool persistent = true, int weight = 1, int timeout = 1, int retry_interval = 15, bool status = true)
bool setServerParams(string host, int tcp_port = 11211, int timeout = 1, int retry_interval = 15, bool status = true)
