Linux下安装Memcache

Memcache是一个开源项目，它是一个高性能的分布式的内存对象缓存系统，通过在内存里维护一个统一的巨大的Hash表，能够用来存储各种格式的数据。

1: 还是下载

Memcache是用C编写的，要用到C的libevent来处理接口点击下载memcached-1.4.0.tar.gz
下载libevent-2.0.13-stable.tar.gz下载memcache-3.0.6.tgz

我下载到了/root/Downloads

2:解压编译

a：先安装libevent

#cd /Downloads
#tar zvxf libevent-2.0.13-stable.tar.gz
#cd libevent-2.0.13-stable
#./configure --prefix=/usr
#make
#make install

查看下安装是否成功

# ls -al /usr/lib | grep libevent

b. 安装memcached

#cd ..
#tar zxvf memcached-1.4.0.tar.gz
#cd memcached-1.4.0
# ./configure –with-libevent=/usr
# make
# make install

c. 安装memcache

#cd ..
#tar vxzf memcache-3.0.6.tgz
#cd memcache-3.0.6
#/usr/local/php/bin/phpize
#./configure –enable-memcache –with-php-config=/usr/local/php/bin/php-config –with-zlib-dir
#make
#make install
#gvim /etc/php5/apache2/php.ini

修改php.ini中的extension_dir = “./”

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

添加

extension=memcache.so

3: 启动和关闭

#/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重启apache
sudo /etc/init.d/apche2 restart

4：测试

< ？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sudosudo apt-get install memcached启动
memcached -d -m 128 -p 11211 -u root -l 127.0.0.1太轻松了。。。Linux安装xdebug.（Debian,Ubuntu）Linux（CentOS）系统各个目录的作用详解相关资讯 Linux安装 memcache
