linux下编译安装memcached服务,linuxmemcached

系统:Ubuntu 13.10
第一步:安装libevent-dev

$aptitude search libevent-dev
$aptitude install libevent-dev

第二步:下载memcached并安装
官网地址:http://memcached.org/

$wget -c http://www.memcached.org/files/memcached-1.4.17.tar.gz
$tar -zxvf memcached-1.4.17.tar.gz
$cd memcached-1.4.17
$./configure --prefix=/usr/local/memcached
$ make
$ sudo make install

第三步:启动memcached

$cd /usr/local/memcached
$./memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211 -P /tmp/memcached.pid

第三步:检查是否安装成功

$ps -aux | grep memcache #法1
$netstat -antu | grep 11211 #法2
$telnet localhost 11211 #法3

常用命令
启动memcached服务

#./memcached -d -m 1024 -u root -l 127.0.0.1 -p 11211 -P /tmp/memcached.pid

关闭memcached服务

#kill `cat /tmp/memcached.pid`

linux 安装PHP的memcached扩展

你先确定一下是memcache还是memcached这两者是有区别的。
telnet成功证明memcache安装成功。
phpinfo显示memcached那这也没问题

可你说
使用官方的测试memcached的PHP文件没用,页面提示500错误
不知你使用的是不是类似这样的代码。
$mem = new Memcache;
$mem->connect("192.168.x.y", 11211)or die ("Could not connect");

$mem->set('key', 'This is a test!', 0, 60);
$val = $mem->get('key');
echo $val;
?>

注意看第一行。。$mem = new Memcache;

如果你的服务器支持是memcached的话就在phpinfo里显示的是memcached
如果是memcache的话那就只会显示memcache

memcached是php的一个扩展。
所以你用new memcache去实例memcached会出500也正常。
 

我以前用linux安装的memcached在java程序中是好用的现在我在windows上安装memcached进程上已经有memcached

先用telnet连接一下windows所在电脑的memcached开放的监听端口,看是否能够联通
