centos6.5 Memcache的安装

Memcache的安装
1.分别下载memcached和libeventWget http://memcached.org/files/memcached-1.4.25.tar.gzwget https://cloud.github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
2.先安装libevent：
# tar zxvf libevent-2.0.21-stable.tar.gz# cd libevent-2.0.21-stable
# ./configure --prefix=/usr
# make
# make install 3.测试libevent是否安装成功ls -al /usr/lib |grep libevent 4.安装memcached，同时需要安装中指定libevent的安装位置：
# tar zxvf memcached-1.2.0.tar.gz
# cd memcached-1.2.0
# ./configure --with-libevent=/usr
# make
# make install 5.测试是否成功安装memcached：
# ls -al /usr/local/bin/mem* 6.启动memcached/usr/local/bin/memcached -d -m 10 -u memcache -p 11211 -c 256 -P /tmp/memcached.pid
-d选项是启动一个守护进程，
-m是分配给Memcache使用的内存数量，单位是MB
-u是运行Memcache的用户，我这里是root，
-l是监听的服务器IP地址-p是设置Memcache监听的端口，最好是1024以上的端口，
-c选项是最大运行的并发连接数，默认是1024，按照你服务器的负载量来设定，
-P是设置保存Memcache的pid文件测试：#Telnet localhost 11211Trying 127.0.0.1...Connected to localhost.Escape character is '^]'.#set test 0 0 10#test_valueSTORED#get testVALUE test 0 10test_valueEND#quitConnection closed by foreign host. 7.关闭memcachedkill `cat /tmp/memcached.pid`安装memcache的php扩展 1.下载memcache:wget http://pecl.php.net/get/memcache-2.2.7.tgz 2.安装PHP的memcache扩展tar vxzf memcache-2.2.7.tgz
cd memcache-2.2.7
/usr/local/php/bin/phpize （yum安装的php执行/usr/bin/phpize）
./configure –enable-memcache --with-php-config=/usr/local/php/bin/php-config --with-zlib-dir （yum安装的php执行 ./configure --enable-memcache --with-php-config=/usr/bin/php-config --with-zlib-dir)
make
make install 若没有phpize命令 yum install php-devel 3.上述安装完后会有类似这样的提示：Installing shared extensions: /usr/lib64/php/modules/ 4.修改/etc/php.iniextension_dir = "/usr/lib64/php/modules/"extension=memcache.so 5.重新启动apache，启动memcachedservice httpd restart运行下面的php文件，如果有输出hello world!,表示环境搭建成功<?php$mem = new Memcache;$mem->connect('127.0.0.1',11211);$mem->set('test','hello world!',0,10);$val = $mem->get('test');echo $val;?>
