Mencached的基本架构搭建
Mencached基本部署
Mamcached概述
memcached是一套分布式的高速缓存系统,运行在内存中。memcached缺乏认证以及安全管制,这代表应该将memcached服务器放置在防火墙后。

实验准备
实验步骤
memcached服务端
1、安装环境包
[root@localhost libevent-2.1.8-stable]# yum install gcc gcc-c++ make -y
2、安装Libevent软件本体
挂载软件包,并到挂载目录下解压
[root@localhost memcached]# tar zxf libevent-2.1.8-stable.tar.gz -C /opt/
[root@localhost memcached]# cd /opt/libevent-2.1.8-stable/
//配置并编译安装
[root@localhost libevent-2.1.8-stable]# ./configure \
--prefix=/usr/local/libevent
[root@localhost libevent-2.1.8-stable]# make && make install
3、配置、安装Memcached
[root@localhost memcached]# tar zxf memcached-1.5.6.tar.gz -C /opt/
[root@localhost memcached]# cd /opt/memcached-1.5.6/
[root@localhost memcached-1.5.6]# ./configure \
--prefix=/usr/local/memached \
--with-libevent=/usr/local/libevent/
[root@localhost memcached-1.5.6]# make && make install
//建立软链接
[root@localhost memcached-1.5.6]# ln -s /usr/local/memached/bin/* /usr/local/bin/
启动服务
[root@localhost memcached-1.5.6]# memcached -d -m 32m -p 11211 -u root
//“-d”:以守护进程的方式运行(后台运行)
//“-m”:指定最大使用内存大小
//“-p”:指定端口
//“-u”:指定用户
[root@localhost memcached-1.5.6]# netstat -atnp | grep 11211
tcp 0 0 0.0.0.0:11211 0.0.0.0:* LISTEN 12591/memcached
tcp6 0 0 :::11211 :::* LISTEN 12591/memcached
#关闭防火墙和安全功能
[root@localhost memcached-1.5.6]# systemctl stop firewalld.service
[root@localhost memcached-1.5.6]# setenforce 0
4、安装Telent用于连接Memcached
[root@localhost memcached-1.5.6]# yum install telnet -y
//连接memcached
[root@localhost memcached-1.5.6]# telnet 192.168.142.66 11211
Trying 192.168.142.66...
Connected to 192.168.142.66.

客户端
安装LAMP架构
详情见本人博客 LAMP架构之Discuz论坛(实操部分)https://blog.51cto.com/14449528/2447886
论坛搭建部分可不做
1、数据库中进行提权
[root@localhost ~]# MySQL -uroot -p
mysql> create database sky;
mysql> grant all on sky.* to 'skyuser'@'%' identified by '123123';
mysql> flush privileges;
2、测试PHP工具能否连接数据库
[root@localhost htdocs]# vim /usr/local/httpd/htdocs/index.php
Success!!!";
else echo "Fail!!";
mysql_close();
?>
3、安装、配置memcache客户端
[root@localhost memcached]# tar zxf memcache-2.2.7.tgz -C /opt/
[root@localhost memcached]# cd /opt/memcache-2.2.7/
[root@localhost memcache-2.2.7]# /usr/local/php5/bin/phpize //为memcache生成启动脚本
[root@localhost memcache-2.2.7]# ./configure \
--enable-memcache \
--with-php-config=/usr/local/php5/bin/php-config
//编译&安装
[root@localhost memcache-2.2.7]# make && make install
修改PHP的配置文件
[root@localhost memcache-2.2.7]# vim /usr/local/php5/php.ini
//736行后添加
extension_dir = "/usr/local/php5/lib/php/extensions/no-debug-zts-20131226/"
extension = memcache.so
4、建立测试页面
[root@localhost memcache-2.2.7]# vim /usr/local/httpd/htdocs/index.php
connect('192.168.142.136',11211); //memached服务端地址
$memcache->set('key',Memcache test Successfull!!!',0,60);
$result = $memcache->get('key');
unset($memcache);
echo $result;
?>
