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。
名称 | 角色 | 地址 |

centos7-1 | 服务端 | 192.168.142.66 |
centos7-2 | 客户端 | 192.168.142.77 |
安装环境包
[ libevent-2.1.8-stable]# yum install gcc gcc-c++ make -y
安装Libevent软件本体
[ memcached]# tar zxf libevent-2.1.8-stable.tar.gz -C /opt/ [ memcached]# cd /opt/libevent-2.1.8-stable/ //配置并编译安装 [ libevent-2.1.8-stable]# ./configure --prefix=/usr/local/libevent [ libevent-2.1.8-stable]# make && make install
配置、安装Memcached
[ memcached]# tar zxf memcached-1.5.6.tar.gz -C /opt/ [ memcached]# cd /opt/memcached-1.5.6/ [ memcached-1.5.6]# ./configure --prefix=/usr/local/memached --with-libevent=/usr/local/libevent/ [ memcached-1.5.6]# make && make install //建立软链接 [ memcached-1.5.6]# ln -s /usr/local/memached/bin/* /usr/local/bin/
启动服务
[ 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 [ 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 [ memcached-1.5.6]# systemctl stop firewalld.service [ memcached-1.5.6]# setenforce 0
安装Telent用于连接Memcached
[ memcached-1.5.6]# yum install telnet -y //连接memcached [ memcached-1.5.6]# telnet 192.168.142.66 11211 Trying 192.168.142.66... Connected to 192.168.142.66. Escape character is ‘^]‘.
安装LAMP架构
详情请见本人之前的博客,里面有详细部署过程,这里就不在赘述了
博客地址:
数据库中进行提权
[ ~]# mysql -uroot -p mysql> create database sky; mysql> grant all on sky.* to ‘skyuser‘@‘%‘ identified by ‘123123‘; mysql> flush privileges;
测试PHP工具能否连接数据库
```php+HTML
[ htdocs]# vim /usr/local/httpd/htdocs/index.php
<?php
$link=mysql_connect(‘192.168.142.132‘,‘skyuser‘,‘123123‘);
if($link) echo "<h1>Success!!!</h1>";
else echo "Fail!!";
mysql_close();
?>
**安装、配置memcache客户端** ```java [ memcached]# tar zxf memcache-2.2.7.tgz -C /opt/ [ memcached]# cd /opt/memcache-2.2.7/ [ memcache-2.2.7]# /usr/local/php5/bin/phpize //为memcache生成启动脚本 [ memcache-2.2.7]# ./configure --enable-memcache --with-php-config=/usr/local/php5/bin/php-config //编译&安装 [ memcache-2.2.7]# make && make install
修改PHP的配置文件
[ 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
建立测试页面
```php+HTML
[ memcache-2.2.7]# vim /usr/local/httpd/htdocs/index.php
<?php
$memcache = new Memcache();
$memcache->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;
?>
