• 在server节点安装Libevent程序；

[[email protected] ~]# ls

libevent-release-1.4.15-stable.tar.gz  memcached-1.5.10.tar.gz

[[email protected] ~]# tar zxvf libevent-release-1.4.15-stable.tar.gz -C /usr/src/

[[email protected] ~]# cd /usr/src/libevent-release-1.4.15-stable/

[[email protected] libevent-release-1.4.15-stable]# ./autogen.sh

[[email protected] libevent-release-1.4.15-stable]# ./configure --prefix=/usr/local/libevent

[[email protected] libevent-release-1.4.15-stable]# make && make install

[[email protected] libevent-release-1.4.15-stable]# cd

[[email protected] ~]# ln -s /usr/local/libevent/lib/libevent* /usr/lib64/

 

• 在server节点安装Memcached程序；

[[email protected] ~]# tar zxvf memcached-1.5.10.tar.gz -C /usr/src/

[[email protected] ~]# cd /usr/src/memcached-1.5.10/

[[email protected] memcached-1.5.10]# ./configure --prefix=/usr/local/memcached --with-libevent=/usr/local/libevent/

[[email protected] memcached-1.5.10]# make && make install

[[email protected] memcached-1.5.10]# cd

 

• 在server节点配置优化Memcached服务；

[[email protected] ~]# ln -s /usr/local/memcached/bin/* /usr/local/bin/

[[email protected] ~]# memcached -d -m 128m -u root ##启动memcached服务

[[email protected] ~]# netstat -utpln |grep mem

tcp        0      0 0.0.0.0:11211           0.0.0.0:*               LISTEN      10748/memcached

 

 

• 在client节点安装lamp应用平台；

[[email protected] ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

[[email protected] ~]# yum -y install httpd mariadb-server mysql php php-devel php-mysql

 

• 在client节点安装LibMemcached程序；

[[email protected] ~]# ls

libmemcached-1.0.18.tar.gz  memcached-2.2.0.tgz

[[email protected] ~]# tar zxvf libmemcached-1.0.18.tar.gz -C /usr/src/

[[email protected] ~]# cd /usr/src/libmemcached-1.0.18/

[[email protected] libmemcached-1.0.18]# ./configure --prefix=/usr/local/libmemcached --with-memcached=/usr/local/memcached ##需要指定mem扩展组件的安装位置

[[email protected] libmemcached-1.0.18]# make && make install

[[email protected] libmemcached-1.0.18]# cd

 

• 在client节点安装Memcached扩展组件（Memcached api）；

[[email protected] ~]# yum -y install zlib zlib-devel

[[email protected] ~]# tar zxvf memcached-2.2.0.tgz -C /usr/src/

[[email protected] ~]# cd /usr/src/memcached-2.2.0/

[[email protected] memcached-2.2.0]# phpize

[[email protected] memcached-2.2.0]# ./configure --enable-memcached --with-php-config=/usr/bin/php-config --with-libmemcached-dir=/usr/local/libmemcached/ --disable-memcached-sasl

注解：

--enable-memcached ##开启memcached api功能

--with-php-config=/usr/bin/php-config ##指定php扩展命令所在位置

--with-libmemcached-dir=/usr/local/libmemcached/ ##指定上述libmemcached软件的安装位置

--disable-memcached-sasl ##关闭memcached的sasl功能

 

[[email protected] memcached-2.2.0]# make

[[email protected] memcached-2.2.0]# make test

[[email protected] memcached-2.2.0]# make install

Installing shared extensions:     /usr/lib64/php/modules/

[[email protected] memcached-2.2.0]# ls /use/lib/64/php/modules/

curl.so      json.so       mysqli.so  pdo_mysql.so  pdo_sqlite.so  sqlite3.so

fileinfo.so  memcached.so  mysql.so   pdo.so        phar.so        zip.so

[[email protected] memcached-2.2.0]# cd

 

• 在client节点配置php支持Memcached组件；

[[email protected] ~]# vi /etc/php.ini ##末尾追加

extension_dir = /usr/lib64/php/modules/

extension = memcached.so

[[email protected] ~]# systemctl start httpd

[[email protected] ~]# netstat -utpln |grep 80

tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      35528/httpd

[[email protected] ~]# cat <<END >/var/www/html/index.php

<?php

phpinfo();

?>

END

[[email protected] ~]# vi /var/www/html/test.php

<?php

$memcache = new Memcached();

$memcache->addServer('192.168.100.101',11211);

$memcache->set('key','Memcache test sussessful!',0,60);

$result = $memcache->get('key');

unset($memcache);

echo $result;

?>

 

• 测试访问Memcached API功能；
• 

 

[[email protected] ~]# yum -y install telnet

[[email protected] ~]# telnet 192.168.100.101 11211

get key

VALUE key 3932160 25

Memcache test sussessful!
